**** BEGIN LOGGING AT Sun Sep 22 03:00:00 2013 Sep 22 03:34:55 just basic junit would work fine for testing Sep 22 03:35:14 you can right click and run as test even Sep 22 03:35:19 just curious what you guys think of cm going into business Sep 22 03:37:07 pfn: How do you setup your tests to be able to run them in Robitium and in Android? Sep 22 03:37:52 I only use plain instrumented tests these days Sep 22 03:38:01 some plain java tests, too Sep 22 03:38:50 pfn: instrumented tests? Sep 22 03:39:21 standard android sdk unit tests Sep 22 03:39:47 look at android.test. * Sep 22 03:43:02 Sorry, I meant roboelectric Sep 22 03:48:59 robolectric just run as plain java tests Sep 22 03:49:09 add the jar to class path and go Sep 22 04:17:42 <^cheeky> hello , i take it that GC_FOR_ALLOC is pretty bad, because, your almost out of memory... i have implemented, image scaling , LRU memory caching, LRU disk caching .. but yet i see a ton of GC_ALLOC .. i am not sure if you have to use soft references and a hash set lessen this, but i tried using BitmapFactory.Options.inBItmap, any advice would be greatly appreciated Sep 22 04:23:28 ^cheeky: http://stackoverflow.com/questions/11260761/is-gc-for-alloc-more-serious-when-investigating-memory-usage Sep 22 04:25:47 <^cheeky> f2prateek: yeah i was reading that link and iam about to read the memory analysis tool , thank you Sep 22 04:26:07 <^cheeky> f2prateek: do you use soft references ? Sep 22 04:26:58 <^cheeky> thank you Sep 22 04:27:10 I used to follow the guides at https://developer.android.com/training/displaying-bitmaps/index.html Sep 22 04:27:19 Now I just use picasso Sep 22 04:27:40 https://github.com/square/picasso Sep 22 04:29:57 <^cheeky> you the second person who mentioned it ..heh Sep 22 04:30:13 <^cheeky> so you actually study the code, or do you just use it in your apps Sep 22 04:31:58 I'm familiar with some parts of the library Sep 22 04:31:59 Nothing wrong with having your implementation, I just got tired of re-writing it for every app Sep 22 04:34:37 <^cheeky> true, blah i dunno i wasted too much time, trying to figure things out, i guess the images load really fast with what i have .. just a lil with seeing GC, i just so badly want to see it work on my code, but yeah right now its smooth with the DISK and MEMOry LRU, just need to preload some of the :) Sep 22 04:34:42 <^cheeky> i am tiiiired Sep 22 05:04:49 anyone wanna see a first screeny of my hackathon project? Sep 22 05:04:49 :P Sep 22 05:06:44 <^cheeky> i dunno you gonne gimme some dirty link :P Sep 22 05:07:29 lol Sep 22 05:28:01 I'm using SimonVT's menudrawer in my application. The menu contains a radiogroup, and on selection of an item from it, I need to change the listview's adapter on the home screen. What is the best way to implement this functionality? Sep 22 05:31:45 Can I do this with fragments that contains listviews in each of them? Sep 22 05:32:17 My first list is of "customers" and the other seconds one contains "orders" Sep 22 05:32:52 What I need to do is to switch between these two lists on selecting a radio button from the drawer menu. Sep 22 05:40:00 anybody? Sep 22 05:51:44 The upcoming BBM for android is supported by which versions of android? Sep 22 05:54:18 <^cheeky> napster: hey , from what i know of fragments .. they are modular .. so you can do what you just described .. use the the fragment manager to switch Sep 22 05:54:34 <^cheeky> but i am not sure Sep 22 05:55:02 ^cheeky: ok, I'm giving it a try now. Sep 22 05:55:30 Ok, time to do feature freeze so I stop dicking around by adding stuff that sounds cool. Sep 22 05:55:46 <^cheeky> napster: just to let you know i havent used .. menu drawers or anything :( Sep 22 05:56:24 not a problem cheeky. I'm experimenting with it. Will let you know the results. Sep 22 05:56:37 <^cheeky> :) k Sep 22 05:57:22 <^cheeky> anyone .. know any good video on android .. you guys could recommend, Sep 22 05:57:51 Video? Sep 22 05:58:25 Aside from the Google IO sessions? Sep 22 05:58:40 <^cheeky> yeah .. just tried, and i cant read anymore lol i am cooking some thai chicken and drinking a corona, want to watch something regarding android, Sep 22 05:59:27 <^cheeky> yeah right now i am watching memory management 2011 Sep 22 05:59:41 <^cheeky> watching that video .. showed me how bad this bloody app is,!!!! Sep 22 05:59:57 <^cheeky> i am leaking memory lol , my heap size keeps growing LOL Sep 22 06:02:55 ^cheeky, Don't remind me about memory Sep 22 06:03:06 I have to give a presentation about how context leaking works andhow to avoid it on Tues. Sep 22 06:03:11 <^cheeky> s0 android and windows are kinda same with regards to code, as in they support so many different phones, and using the apis .. across them is a pain i dunno but it looks like it Sep 22 06:03:36 <^cheeky> 0oo Sep 22 06:03:54 <^cheeky> i wish i could have sit for that, i would like to know Sep 22 06:04:31 Context leaking is easy to avoid. Sep 22 06:04:46 If you need to keep a context around, use the application context. If you don't, then why are you keeping a context around? >_> Sep 22 06:04:47 <^cheeky> *sat Sep 22 06:04:49 <^cheeky> blaah Sep 22 06:05:52 <^cheeky> k .. so n00b question .. :( .. context is what an Activity would be derived from , like how Object is to JAva ? Sep 22 06:05:57 Nilium, Now ELI5 to a bunch of people who need hand holding for the hello world tutorial Sep 22 06:05:58 thats what I have to do Sep 22 06:06:01 with pretty images and wahtnot Sep 22 06:06:11 ELI5? Sep 22 06:06:48 Ah. Sep 22 06:07:11 Wait, how do you get simpler than "don't keep it around if you don't need it, and if you do, use the application context"? Sep 22 06:07:29 Do you have to start making car analogies, which is apparently the only thing programmers can come up with Sep 22 06:13:04 <^cheeky> hmm DDMS , should have memory anlayzer and dominator tree? Sep 22 06:14:47 I think so? Sep 22 06:15:21 <^cheeky> its okay ... ill google it when i get some Zzzz Sep 22 06:15:25 <^cheeky> *after Sep 22 06:15:36 <^cheeky> well i am using AS Sep 22 06:16:30 <^cheeky> i was able to dump the HPROF file , but i didnt get far to open it .. i think there might me having to convert the file Sep 22 07:47:26 does anyone know how to set a max zoom level for a GoogleMap object? Sep 22 07:53:45 sorry but i need to put advertising in my game to potentialize realize profits Sep 22 07:53:54 any recommendations on doing that? Sep 22 07:54:05 <^cheeky> http://stackoverflow.com/questions/10517848/modify-the-max-zoom-level-of-a-google-map-type Sep 22 07:54:10 potentially Sep 22 07:54:17 <^cheeky> CavemanNinja: http://stackoverflow.com/questions/10517848/modify-the-max-zoom-level-of-a-google-map-type Sep 22 07:55:29 http://developer.android.com/training/monetization/ads-and-ux.html#ObtainPubAccountAndSDK Sep 22 07:57:02 admobhttps://developers.google.com/mobile-ads-sdk/?csw=1 Sep 22 07:57:14 ok sweet Sep 22 07:58:51 ^cheeky: thanks but that is for the google maps web api, im trying to do it using android maps api v2 Sep 22 08:01:24 <^cheeky> CavemanNinja: welcome and i am sorry i could have not been much of help but i think some other ip connected could be more of an assistance to you Sep 22 08:01:24 i tried checking the zoom level in an onCameraChangeListener and adjusting the zoom level if it is over my desired maximum but the lsitener is called after animating the zoom out so it looks like it bounces back Sep 22 08:02:09 <^cheeky> oh @ what state does this happen @ Sep 22 08:02:43 <^cheeky> sorry i have no idea .. about animations nor using the maps api.. still new to android dev Sep 22 08:03:27 no worries :) Sep 22 08:05:37 <^cheeky> hmm interesting problem tho Sep 22 08:06:07 <^cheeky> i am new . but you using a activity + fragment Sep 22 08:07:44 Yeah, specifically a MapFragment, it has a GoogleMap object that is the main class used for accessing the GoogleMaps Api Sep 22 08:08:31 the GoogleMap object has getMax/MinZoomLevel methods but no set.. Sep 22 08:08:44 map:cameraZoom Sep 22 08:10:09 you can disable zooming all together if you want Sep 22 08:11:32 No I want to be able to zoom in as much as possible but set a maximum zoom level. Sep 22 08:11:58 i think i may have found an answer ill try it out and report back Sep 22 08:16:31 It seems the best way around this limitation is the disable the maps native zoom controls and define your own. Sep 22 08:21:39 Hi Sep 22 08:25:09 Is it easy to get the camera for the phone, and put an overlay image on top of it in real time? Sep 22 08:30:05 Ok, screw feature freeze, had to add pet mode: https://dl.dropboxusercontent.com/u/31892/Screenshots/psadh.png Sep 22 08:37:59 Could image be blurry when scalling down ? Sep 22 08:56:28 hello. can anyone explain, why "@color/white" does not work? it says unresolved symbol. - android studio 0.2.9 Sep 22 09:01:29 try @android:color/white Sep 22 09:04:30 kjeldahl: Gradle: String types not allowed (at 'android:actionMenuTextColor' with value 'android:color/white'). Sep 22 09:04:51 oh sry, forgot the @ Sep 22 09:07:56 well that works. but e.g. @android:color/red does not Sep 22 09:13:00 That's because red isn't defined. Sep 22 09:13:16 You should go look at R.color, probably. Sep 22 09:20:23 Nilium: R.color contains only the colors that I have defined with . I am wondering because many tutorials say @color/xxx Sep 22 09:29:28 That's not the R.color I'm talking about Sep 22 09:29:33 I mean android.R.color Sep 22 09:49:37 hi Sep 22 10:20:09 hi all can someone help me with the broadcastreceiver ? Sep 22 10:20:13 this is the manifest Sep 22 10:20:34 http://pastebin.com/Fz0CHKGh Sep 22 10:21:26 and this is the java file Sep 22 10:21:27 http://pastebin.com/dwXr4az7 Sep 22 10:21:52 i don't know if i miss something because the application doesn't start Sep 22 10:26:40 Hi, anybody with experience using twitter4j? Sep 22 10:26:46 eclipse compile it properly, maybe the problem is that i don't use an onCreate Sep 22 10:26:54 methode Sep 22 10:27:11 I wanna pass a list of Status to my fragment, so I need to pass them in a bundle Sep 22 10:27:33 but if i use i can't use it with Broadcastreceive extends Sep 22 10:27:51 Status is said to be serializable, but when I call putSerializable on my list of status Sep 22 10:27:54 itdoesnt work Sep 22 10:28:40 any idea how i an pass an list of status to my bundle without having to recreate the serialization process myself? Sep 22 10:29:12 Yeah I've used twitter4j Sep 22 10:29:23 I used a content provider to manage my statuses tho Sep 22 10:29:28 http://twitter4j.org/javadoc/twitter4j/ResponseList.html I should be able to seralize it no? Sep 22 10:29:42 it implements serailizable Sep 22 10:29:45 a content provider Sep 22 10:30:21 what are you doing exactly, you create a list of status but then you can't put it in a bundle? Sep 22 10:31:42 yes Sep 22 10:31:47 i get a list of statuses Sep 22 10:31:53 i want to pass this list to my fragment list Sep 22 10:31:56 to display them Sep 22 10:32:06 so i need to pass them in a bundle Sep 22 10:32:14 i mean this is what i thought Sep 22 10:32:55 I would recommend using a content provider, get the statuses, add them to the content provider, then you can easily display then using a cursor in the list fragment Sep 22 10:33:47 hm ok Sep 22 10:33:50 i will check that Sep 22 10:35:13 http://developer.android.com/guide/topics/providers/content-provider-basics.html Sep 22 10:35:22 http://developer.android.com/guide/components/loaders.html Sep 22 10:35:57 i'll dig up my content provider and listfragment Sep 22 10:36:47 https://gist.github.com/jalbasri/6658755 Sep 22 10:36:48 because what i ve seen is like people doing the twitter request directly in the fragment code Sep 22 10:36:54 that way they dont have to pass anything Sep 22 10:37:00 https://code.google.com/p/hilda-twitter/source/browse/samples/TimelineHilda/src/com/hilda/twitter/samples/timeline/fragments/ListFragment.java?spec=svn20&r=20 Sep 22 10:37:05 this is how I understood it Sep 22 10:37:08 thanks Sep 22 10:38:34 It's fairly common to have the fragment capable of fetching the data, or having a local cache you update by some asynchronous means. Sep 22 10:38:59 passing data to display in bundle is actually reasonably rare because android can reconstruct the fragment and pass you stale data Sep 22 10:39:17 if the data is live and changes, this leads to application displaying potentially very old information Sep 22 10:39:22 cant you just have an updateList method in your fragment and pass it the ResponseList obj? Sep 22 10:40:09 so we should basically do the statuses request inside the fragment Sep 22 10:40:14 I also recommend *against* most of android abstractions like contentprovider. CP's primary value is being able to share data with *other* applications. If you are working within one application only, you can directly pass Cursor objects around. Sep 22 10:42:41 anyway, that class you linked seems like it might be doing reasonable things. Sep 22 10:42:46 but content providers make it so easy to have a service data asynchronously and have the ui update as it refreshes. What would be the reasoning not to use them? Sep 22 10:43:34 I find the abstraction clumsy and complicated, that's all. It's not too difficult to send an intent or something similar when your update task finishes, and the receivers of intent reopen the cursor and check the new data. Sep 22 10:44:10 and I was told android comes with some nifty observer-observable abstraction though I forgot what it was called, but it's apparently the same one contentproviders use Sep 22 10:44:37 what about persisting the data once you close? Sep 22 10:45:11 observer-observable it sounds familiar i read something about it months ago but cant recall... Sep 22 10:45:26 close the application? I guess if you have structured data, sqlite data persistence is the favorite choice. Sep 22 10:45:44 and if it can't be recreated cheaply Sep 22 10:49:03 i think the content provider is a good way to abstract the sqlite db + manage the cursors at the same time. Sep 22 10:49:31 but if he doesnt need to persist and its just a single list its probably overkill Sep 22 10:50:58 afaik cursoradapters are perfectly capable of managing the cursors, whatever that means Sep 22 10:51:30 you just hand one of them to the adapter and it takes care of it as long as it holds it. If you fail to close it all properly I'm sure the GC or application's exit or similar event will clean everything up, though that could be poor programming. Sep 22 10:52:49 so is this basically the best way to do it? https://code.google.com/p/hilda-twitter/source/browse/samples/TimelineHilda/src/com/hilda/twitter/samples/timeline/fragments/ListFragment.java?spec=svn20&r=20 Sep 22 10:52:51 somehow Sep 22 10:59:06 droidheads, I got a small question for you, is the only Maps API for Android Google Maps? Sep 22 11:04:13 jrm2k6: would have to examine the twitter API definition, see if it has local caching, stuff like that. It's probably well engineered if it's official, and if that's the way they recommend using it. Trusting random source from the internet isn't generally the way to go. Sep 22 11:04:40 alankila: I agree, but I m just talking about the principle itself Sep 22 11:04:58 I feel like it is not a good practice to do asynchronous request in a fragment class Sep 22 11:04:59 no? Sep 22 11:05:09 the fragment class should just received data and display it Sep 22 11:05:24 I have teams that travel collecting data. They are currently using old WinCE devices which has a proprietary data collection form, that syncs with a central server when they're connected to wifi. I'd like to replicate this functionality on android (or hire someone to), taking advantage of the camera and gps would be a bonus. Is there any problem doing so as far as publishing such an app? Any advice? Sep 22 11:05:51 I already explained that you shouldn't put the data in a bundle because that risks getting pretty stale when android recreates the fragment from the bundle when it has to. Sep 22 11:06:07 and that kind of prevents the fragment from displaying realtime updates should there be realtime updates Sep 22 11:06:29 if you think these are good things then by all means stuff everything you want in a bundle or something and construct view from that, but I doubt these are good goals Sep 22 11:06:50 alright Sep 22 11:08:25 jrm2k6: wherever you do the acquisition of the data you could just have a function in the listFragment like updateList(List) and call that with the list you get from twitter, no? Sep 22 11:08:48 and in that function update the list adapter Sep 22 11:08:55 Yep thats true Sep 22 11:08:59 I will check it that way Sep 22 11:09:00 after lunch Sep 22 11:09:01 :D Sep 22 11:12:41 "However, the installation process will start automatically only if the user has configured their Settings to allow the installation of apps from unknown sources." So would I could set it to "unknown sources", install the app, unset it, give them the device -- and still be able to push updates to the application code? Or obtain permission to become a "known source" without my code being public? Sep 22 11:17:14 i am using eclipse, but since the update to 3.8 my android build process seems broken, i get this when trying to launch my app http://pastebin.com/MnC8AeYr Sep 22 11:17:27 also "Build Project" is disabled in the menu Sep 22 11:49:19 Anyone knows if it's possible to cancel all pending AsyncTasks running on the SERIAL_EXECUTOR? I'm doing a HTTP request each time the user presses a key in AutoCompleteTextView to fetch keyword suggestions - but if the user writes fast then it'll take a while before the last request gets through. Sep 22 11:52:01 LtRipley: Update to 3.8? Isn't 4.3 the latest? Sep 22 11:52:50 kakazza: i guess ubuntu is always a little bit behind Sep 22 11:53:07 i am doing some sdk updates now, maybe that was the issue Sep 22 12:10:02 Anyone can tell me what kind of control is this one? ( http://goo.gl/a3unMj ). The Mobile selection ¿button?. I want to create on my own app, a kind of button with pre-defined options Sep 22 12:17:16 I found it, spinners (facepalm) Sep 22 12:31:45 so sdk-updates didn't solve it Sep 22 12:32:26 now that i cleaned my build directories, it basically says that it cannot find R Sep 22 12:32:59 but it doesn't say anything about errors in the xml Sep 22 12:33:09 is there a way to many create the R class? Sep 22 12:33:51 in my gen folder there is only one file, BuildConfig.java Sep 22 12:39:03 LtRipley: There is something wrong with your xml resources Sep 22 12:39:18 When that happens R.java doesn't build Sep 22 12:39:19 it doesn't show any error with the xml Sep 22 12:39:33 i figured that out, but i don't see what would be wrong Sep 22 12:39:34 doesn't mean there isn't a problem Sep 22 12:40:05 that is why i would like to try to build it manually Sep 22 12:41:02 i changed my layout file, but it seems to be correct Sep 22 12:42:43 could it be the order of the builders in my project properies? Sep 22 13:03:16 Could anyone help me with a quick answer? Sep 22 13:03:20 myHandler.handleMessage(myHandler.obtainMessage(0, i, 0)); Sep 22 13:03:20 return; Sep 22 13:03:20 myUri = UriManager.getInstance().getUri(); Sep 22 13:03:20 break; Sep 22 13:03:38 Why would i want to return after obtaining the message? Sep 22 13:03:38 Use pastebin. Sep 22 13:03:45 Sorry about that Sep 22 13:04:00 I don't know, why do you return? Sep 22 13:04:19 i'm reading through someone else's code Sep 22 13:04:26 I can't seem to make sense of this Sep 22 13:04:30 Ask them Sep 22 13:04:38 It shouldn't work but it does... Sep 22 13:04:44 Out of reach right now Sep 22 13:08:03 there is now way that the code after the return is executed, probably it will just run fine if you delete that code Sep 22 13:08:44 try deleting it, run it and then don't think about it anymore : Sep 22 13:09:11 other peoples code not always makes sense Sep 22 13:09:42 What is interesting to me is that eclipse usually flags cases like this as an error Sep 22 13:09:50 i.e unreachable code Sep 22 13:09:55 but no flag here Sep 22 13:10:27 probably it depends on the context where this code is Sep 22 13:10:43 it is impossible for eclipse to find any occurence of dead code Sep 22 13:11:12 DarkSlay3r, paste the full code. I assume it's a switch? Sep 22 13:11:33 in fact there are multiple pages in the java spec defining when a piece of code is considered reachable Sep 22 13:12:09 It's encapsulated in an if statement Sep 22 13:12:28 DarkSlay3r: as sonOfRa said, you need to post the full code Sep 22 13:12:58 anyways, i wouldn't worry too much about it Sep 22 13:13:32 http://codepad.org/MdSoDax8 Sep 22 13:13:55 i actually can't paste everything but this is the relevant bit Sep 22 13:14:18 What i can Sep 22 13:14:37 't seem to figure out is why eclipse thinks this is fine? Sep 22 13:15:14 I don't think he actually has access to the source code, he's just decompiling some app Sep 22 13:15:41 android studio must use java 1.7 or 1.6 is also valid? Sep 22 13:15:43 depends on the decompiler then :) Sep 22 13:16:35 SimonVT: that is a good explaination, i have seen obfuscated javacode that results in decompiled code like that Sep 22 13:16:49 guess proguard is doing that Sep 22 13:17:01 Well you learn something new everyday... Sep 22 13:20:53 which decompiler are you using? Sep 22 13:21:10 This isn't the channel for decompiling apps Sep 22 13:21:38 sorry ;) Sep 22 13:22:09 so i am still trying to figure out why my R class isn't generated in eclipse, is there any way to check my build config to see what is happening? Sep 22 13:22:24 or maybe manually creating the R class? Sep 22 13:22:33 Switch to a proper ide/build system Sep 22 13:22:45 One that actually tells you when there's errors Sep 22 13:23:04 (that's basically anything but eclipse) Sep 22 13:23:16 this sounds very much like a strongly opiniated advice Sep 22 13:23:20 SimonVT: Lint doesn't pick up all errors that prevent R.java from building Sep 22 13:23:34 i've encountered this problem before Sep 22 13:23:45 Your build system should tell you when there's errors Sep 22 13:24:06 so that's why there is my second question how do i actually do it manually? Sep 22 13:24:39 You can build with with gradle, ant or maven Sep 22 13:25:27 i mean: which process is responsible for generating the R class? Sep 22 13:25:52 as far as i know maven and ant are unaware of android Sep 22 13:26:15 I think this is what he means Sep 22 13:26:16 http://stackoverflow.com/questions/4619162/how-to-generate-r-java Sep 22 13:26:23 aapt generates R Sep 22 13:26:33 The official build system is, at the moment, ant Sep 22 13:26:35 Soon to be gradle Sep 22 13:26:42 Someone else made an android plugin for maven Sep 22 13:26:55 DarkSlay3r: thanks Sep 22 13:27:23 All of them will tell you about errors in your resources that causes R generation to fail Sep 22 13:32:17 SimonVT: sorry, i dont get your point Sep 22 13:33:28 Your R isn't being generated because you have errors in your resources Sep 22 13:33:37 i know that Sep 22 13:33:42 What use is an IDE if it doesn't tell you about those errors, but just silently fails Sep 22 13:33:53 well i got the "eclipse suxx' part Sep 22 13:35:23 If you say so Sep 22 13:36:13 eclipse should die in some horrible place Sep 22 13:38:31 ok, i managed to do it, there was actually nothing wrong with my xml Sep 22 13:38:33 Anyone know why ARM advertises 16x FSAA support on their Mali-T6xx line and it doesn't? Sep 22 13:38:46 http://stackoverflow.com/questions/5590933/manually-modiffying-r-java/5591494#5591494 Sep 22 13:39:12 that was the solution Sep 22 13:48:09 <^cheeky> morning /evening if i want to look at my HPROF file, i need eclipse MAT ? Sep 22 13:50:07 LtRipley: What was the problem? Sep 22 13:51:24 Could image be blurry because of scalling down ? Sep 22 13:54:45 bluesm_: depends on if you mean "antialiased" by "blurry" Sep 22 14:00:14 DarkSlay3r: i don't really know Sep 22 14:00:32 DarkSlay3r: maybe eclipse was confused because to many projects where open or something Sep 22 14:05:04 anyone knows what this error means?

Sep 22 14:08:22 I mean it's like double duty when all the strings practically resemble the actual variable name Sep 22 14:08:28 If you want to do any kind of localization, then yes Sep 22 14:08:53 i'm sorry but what do you mean by localization? Sep 22 14:09:21 oh Sep 22 14:09:28 like language changes?

Sep 22 14:25:00 <^cheeky> do i have to do any further conversion after i dumped HPROF file in android studio-> DDMS and then tried opening it with eclipse MAT but it gives me a parse error, i also tried converted it using hprof-conv tooll available in the tools folder of my android sdk, but i still get the error Sep 22 14:35:54 LtRipley: everything I use for build is here: github.com/PolishBloodProject, I synced branch jb-4.3. Like you said maybe it is possible that library is missing. I will check it out. Sep 22 14:36:29 I'm trying to compile Android 4.3, device is neo v (haida) Sep 22 14:37:03 Maybe it's more suited for #android-root Sep 22 14:40:22 alankila: http://developer.android.com/guide/practices/screens_support.html#density-independence Sep 22 14:40:34 However, bitmap scaling can result in blurry or pixelated bitmaps, which you might notice in the above screenshots. To avoid these artifacts, you should provide alternative bitmap resources for different densities. Sep 22 14:40:39 alankila: ^ Sep 22 15:16:48 bluesm_: your point being? Sep 22 15:19:13 alankila: That they should correct documentation. And say "scaling up" makes your image blurry or pixelated Sep 22 15:19:41 Oh, indeed. Sep 22 15:19:57 if you provide a low-dpi resource and view it on high-dpi, the lack of information relative to surrounding content is probably apparent Sep 22 15:20:20 <|0xD34D|> bluesm_: they do "However, bitmap scaling can result in blurry or pixelated bitmaps, which you might notice in the above screenshots." Sep 22 15:20:43 downscaling generally risks gamma error and loss of contrast Sep 22 15:20:43 upscaling should be avoided whenever possible. Sep 22 15:21:36 * alankila idly wonders if minor deformation grid could help to optimize contrast of a downscaling algorithm Sep 22 15:22:04 |0xD34D| : Right, but it correct only with up scalling not down scalling Sep 22 15:22:22 |0xD34D|: And "above screenshot" are blurry itself.. Sep 22 15:22:34 the downscaling will add antialiasing and the way these algos work is that they make about 20 % average error in component luminosity because they ignore gamma correction Sep 22 15:22:42 <|0xD34D|> and you said "scaling up" so I showed you were they do mention it for "scaling up" Sep 22 15:22:58 but that's generally not treated as blurriness. It's just a loss of contrast which may or may not occur Sep 22 15:24:19 |0xD34D|: Right but they Should point out where they mention for "scaling up" :) Sep 22 15:24:26 <|0xD34D|> and I do believe you can submit patches to the docs for corrections so you should go take care of that Sep 22 15:25:02 |0xD34D|: You could also provide in "bug reports" add the proposition of better screenshots ? Sep 22 15:25:22 <|0xD34D|> why would I do that? Sep 22 15:25:27 |0xD34D|: This screenshot seems to be blurry itself : http://developer.android.com/images/screens_support/density-test-good.png Sep 22 15:25:39 <|0xD34D|> you are the one complaining so be proactive about it Sep 22 15:26:00 alankila: Could you point me to article about it ? How downscaling works ? Sep 22 15:26:09 alankila: Not to complicated ? Sep 22 15:26:41 alankila: Because I pretty much don't know what "gamma" is. Sep 22 15:30:19 bluesm_: I don't have any articules about it, sorry. Most of the time the method used is called linear interpolation. You can reduce image by up to 50 % in a dimension with it. Sep 22 15:31:43 alankila: My understanding is that if you scalling down by 50% it just connect every two pixels to one, With value that is average of those. Sep 22 15:32:20 gamma is the way a component value is mapped to a physical luminosity. It is easiest to comprehend by asking: what is the average brightness between two colors. If you take rgb value like #000 and #fff, is the average #888? No. It's about #bbb, because the mapping is not linear. Sep 22 15:32:20 unfortunately all our algorithms based on linear interpolation output #888 when asked to generated a midpoint color between the two rather than #bbb. This means that scaling images down tends to make them too dark at edges. Sep 22 15:32:38 yes, well, that is ignoring gamma, but that is the process. Scaling by integer factors is easy, you just average pixels but you should take care to average in linear light. Sep 22 15:34:53 http://www.4p8.com/eric.brasseur/gamma.html is a page that goes at ridiculous depth at it Sep 22 15:38:05 I am personally convinced that we will never be rid of this until we stop using color spaces such as sRGB. This is just the kind of topic that is too difficult for most programmers to comprehend, it seems, or care about. The bug plagues everything that deals with graphics, text rendering, whatever, but since nobody understands it, it's hopeless. Sep 22 15:50:54 I've been thinking about making a kick-ass freetype-based text rendering library though. Just to show what it looks like when you do everything as well as possible, and hopefully would yield very favorable comparisons. Sep 22 15:51:18 I think the anti-grain-geometry guy already did it all though Sep 22 16:12:49 Hi, I have an issue with a customeArrayAdapter and a list fragment Sep 22 16:13:02 https://gist.github.com/jrm2k6/6661410 Nothing is inflated but I dont get any error Sep 22 16:13:06 Any idea? Sep 22 16:16:02 is if( row == null ) always false? Sep 22 16:17:15 nope Sep 22 16:17:19 it is going in it Sep 22 16:17:44 is the getView called at all? Sep 22 16:17:48 yep Sep 22 16:17:51 it is called Sep 22 16:18:20 oh I misread your previous answer Sep 22 16:18:21 right Sep 22 16:20:28 <^cheeky> jrm2k6: convertView == null then convertView = getActivity().getLayoutInflater().inflate(R.layout.youritemLayout, parent, false); Sep 22 16:21:06 ^cheeky: where? i mean Sep 22 16:21:09 instead of what? Sep 22 16:21:24 <^cheeky> LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); Sep 22 16:21:48 <^cheeky> i am not 100 % thou.. i am kinda nervouse answering questions here Sep 22 16:21:57 i m will try Sep 22 16:22:09 I have a different approach on inflating as well Sep 22 16:23:15 hmm ^cheeky i m not sure i follow. i m not even using this convertView anywhere except assigning it to row at the beginning of getView Sep 22 16:23:40 replace convertView with row in your case Sep 22 16:23:57 jrm2k6: instead of in onActivityCreated do it in onActivity attached Sep 22 16:25:06 ok i m checking all your solutions Sep 22 16:25:16 I just need to find out the documetation stating those Sep 22 16:26:19 funkbox: onActivityAttached? Sep 22 16:26:46 yees Sep 22 16:28:38 I dont see such a method Sep 22 16:29:18 Hey. I have a question about localization. I'm working on an app that will have support for several different languages. Problem is my boss doesn't know Java, but still would like to have the possibility to add more languages later on. I can't expect him to fire up an installation of Eclipse and recompile the whole project once he's updated the strings.xml file. Sep 22 16:29:55 He does know, however, how to edit an XML file. So I was thinking maybe I should put all the strings in a separate expansion file, and distribute it with the apk file, or is this a bad idea? Sep 22 16:32:51 <^cheeky> jrm2k6: TweetAdapter adapter = new TweetAdapter(getActivity(), R.layout.tweet_detail, testTweet()); to TweetAdapter adapter = new TweetAdapter(testTweet()); then set list adapter and then in your tweet adapter constructor do super(getActivity,0, _data) Sep 22 16:33:05 ihm Sep 22 16:33:13 lemme check Sep 22 16:33:15 <^cheeky> and in the view you get the convertView and give your layout Sep 22 16:33:24 <^cheeky> of your row layout Sep 22 16:33:26 is the android documentation good about this part? Sep 22 16:34:33 alankila: why mapping is not linear ? Sep 22 16:35:04 ^cheeky: I dont have access to get activity in the call to super Sep 22 16:35:59 <^cheeky> jrm2k6: change your constructor to match it Sep 22 16:36:14 ^cheeky: I did Sep 22 16:36:47 <^cheeky> public TweetAdapter(Array Tweet[] _data) Sep 22 16:36:58 but if i follow what you said, it doesnt work, as when i call super() getActivity is not found Sep 22 16:37:13 my adapter doesnt have access to getActivity Sep 22 16:37:30 <^cheeky> yes so make it an inner class of the list fragment Sep 22 16:38:13 hm Sep 22 16:39:55 well, you can also ask the layoutinflater via the static method LayoutInflater.from() Sep 22 16:40:23 LayoutInflater inflater = LayoutInflater.from( parent.getContext() ); Sep 22 16:41:18 Ok i m reading about it buecause i am confused about this layout inflating Sep 22 17:08:00 trying setInstallLocation 2, the process is just killed with no output Sep 22 17:08:06 install location is unchanced Sep 22 17:08:16 changed* Sep 22 17:09:39 the phone's internal memory is full, and it won't do anything now. Sep 22 17:42:03 Anyone knows why in native ARM assembly, some dynamically linked functions are called by jumping directly to the .plt caller of the function, and some jump via an extra indirection/trampoline at the end of the code (for the same function)? Sep 22 17:45:51 bluesm_: the mapping is not linear because of the low precision of 8 bits per component and the desire to encode significant brightness range with it Sep 22 17:46:32 bluesm_: it originally came about because of standards were based on physical hardware and the approximate behavior of the cathode ray tubes afaik Sep 22 17:46:41 or rather, it seems that the code has randomly "long call stubs" vs more direct calls, and I don't see why Sep 22 17:47:04 (I'd expect it to be based on the PC distance, but it isn't) Sep 22 17:49:48 bluesm_: also related is the fact that the eye response to a brightness appears to be logarithmic Sep 22 18:04:59 interesting. http://iloveubuntu.net/smart-scopes-anonymize-images-landing-users-dash-privacy-oriented Sep 22 18:05:17 looks like they realized it was a mistake Sep 22 18:32:35 alankila: I have to learn much more... Thank you very much for your time to help me understand something :) Sep 22 18:32:49 alankila: Thank you very very much :) Sep 22 18:36:57 alankila: so it means that #222222 isn't two times brighter than #111111 ? Sep 22 18:45:13 Hi. I am trying to build the android app of owncloud using the eclipse ADT as given by google. It fails for many reasons, which I am going through them so I can also learn in the process. While searching around online on how to solve them, I came along a claim that bulding it with java 1.7 has a high failure chance, while if java 1.6 is used, all goes fine. Is this true? Sep 22 18:47:26 Why they don't incorporate GitHub to make issue posts regarding Android Documentation ? Sep 22 18:52:35 Night_Elf: this cahnnel is for app developers Sep 22 18:53:07 you'll have more luck with #android Sep 22 18:54:24 f2prateek: I thought of asking it here too. In #android noone seems to tackle this question, so I guessed here there might be people who can tell if java version matters when developing some app (in this case owncloud), or not. Sep 22 18:55:21 Night_Elf, what does it mean for you that you're building with "java 1.7" exactly? Sep 22 18:57:04 Hey there! Sep 22 18:57:29 Mavrik: When I give the command 'java -version' the output gives: java version "1.7.0_40" Sep 22 18:57:50 Android Studio seems to be fantastic, but what do I have to do to make it find my usb connected Nexus4? I'm on Ubuntu. Sep 22 18:57:59 Night_Elf, and which compiler are you using? Sep 22 18:58:00 Mavrik: It actually is what I downloaded from Oracle site. Sep 22 18:58:28 RedNifre, probably what android developer docs say about setting up udev permissions on ubuntu ;) Sep 22 18:59:01 Mavrik: Is it ant you are refering to ? Sep 22 18:59:52 no. Sep 22 19:00:18 it's which of the JDK distributions that include compilers are you using? Sep 22 19:00:22 Never mind, turns out Android Studio is able to find it when I plug it into a different USB port. Very strange, but now it works :) Sep 22 19:03:14 Mavrik: well, I got all the java sdk pack from Oracle and I installed it systemwide, applying all 'update-alternatives' needed. Sep 22 19:04:03 Night_Elf, does it say "Java HotSpot…" when using "-version" or "OpenJDK …" ? Sep 22 19:04:09 that's how you know for sure Sep 22 19:04:24 if you have Oracle HotSpot, 1.7 shouldn't be a problem Sep 22 19:04:33 just make sure that language level for compiler is set for 1.6 Sep 22 19:05:05 f2prateek: I thought of asking it here too. /away Sep 22 19:05:10 oops Sep 22 19:05:47 Mavrik: Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode) Sep 22 19:07:36 Weird, when I use the new Jellybean feature of specifying the parent activity for the up button in the manifest, I get a "new activity started" animation when pressing up, instead of the expected "activity destroyed animation". Sep 22 20:18:53 i am trying to play a mp3 file with MediaPlayer, and it works fine when it is a raw resource, but when i try to play a file from my app local directory it fails Sep 22 20:19:46 i don't even need to call prepare if i use the raw ressource, it just plays Sep 22 20:19:49 what is the difference? Sep 22 20:22:35 It doesn't have access? Sep 22 20:24:26 i am calling exists() and canRead() and both succeed Sep 22 20:24:40 on the file i am feeding to the MediaPlayer Sep 22 20:25:59 i tried a lot of different versions on setting the datasource, but nothing seems to work Sep 22 20:27:40 why not use the raw resource? Sep 22 20:28:52 jeppy: because i load the files from a http server, so they change Sep 22 20:30:06 maybe convert them to raw yourself? I'm sure you'd rather fix the MediaPlayer issue though... Sep 22 20:30:50 LtRipley: If you're testing canRead etc from your own app, that doesn't mean the MediaPlayer has access. So you probably need to put in on "external" memory (/sdcard) or similar, or provide some kind of contentprovider (not sure about the latter, whether a contentprovider can serve files). Sep 22 20:31:28 because the MediaPlayer is a different app, right Sep 22 20:31:33 yes Sep 22 20:32:02 and can i change the permissions? Sep 22 20:34:26 LtRipley: Maybe this can help: http://www.mail-archive.com/android-developers@googlegroups.com/msg12519.html Sep 22 20:35:19 thanks, that seems to be the answer Sep 22 20:35:34 I have no idea if it will work, but hopefully it does. Sep 22 20:35:58 Here's another one: http://stackoverflow.com/questions/3773262/mediaplayer-cant-play-audio-files-from-program-data-folder Sep 22 20:36:37 we will see :) Sep 22 20:43:55 <^cheeky> joozey: thank you about getContext, but would you not want to get the getApplicationContext().getResources() and pass, since it might be prone to memory leaks Sep 22 20:45:42 kjeldahl: yes, it is playing music now :) Sep 22 20:46:08
