**** BEGIN LOGGING AT Fri Jun 14 02:59:58 2013 Jun 14 03:03:01 is android-studio stable enough to start developing with? anyone use it ? Jun 14 03:03:01 i use it, besides user errors (many) there are no probs Jun 14 03:03:01 :) Jun 14 03:03:31 is the native code support solid? i guess thats all i really care about at the moment Jun 14 03:03:53 since i have no android experience at all Jun 14 03:04:20 Hey guys. Reading a bit / watching google i/o videos...this one is about listview Jun 14 03:04:23 no idea on that front Jun 14 03:04:35 says that if you can go with hasStableViews() == true then you're better off Jun 14 03:04:51 stable ids, do you mean? Jun 14 03:04:52 specifically, inserting new items Jun 14 03:04:56 yeah sorry Jun 14 03:04:57 stable ids Jun 14 03:05:15 out of curiosity, can I insert new items and have a pretty little animation of them sliding in? Jun 14 03:05:47 if it has stable IDs then listview can remember where you're scrolled to so when you update the data set or rotate it's nicer Jun 14 03:05:57 yes Jun 14 03:06:33 alex_PP: you can do that without stable ids too with the inbuilt bundle out no ? Jun 14 03:07:00 as in the save/restore instance Jun 14 03:07:57 with stable IDs listview does it for you Jun 14 03:07:58 is that something I can easily test and play with or is there maybe a video so I can see what to expect? Jun 14 03:08:03 don't think it works woth out Jun 14 03:08:06 unless i'm mistaken Jun 14 03:09:46 ProgramMax, http://graphics-geek.blogspot.com/2013/03/devbytes-layout-transitions.html Jun 14 03:09:55 i think that's the video you want Jun 14 03:10:11 i can't watch youtube at work so i'm not 100% Jun 14 03:10:57 checking, thanks Jun 14 03:11:57 that video has #AndroidDev in it and I first thought of a channel, not a hash tag Jun 14 03:12:49 there's more here Jun 14 03:12:49 https://www.youtube.com/watch?v=atH3o2uh_94&list=PLxLa2tjhVPOZ9KMqanm12_xPDBjKPZWgM Jun 14 03:13:10 chet knows his stuff Jun 14 03:13:10 kk will check next. Thanks Jun 14 03:13:39 his blog is good too, but not updated enough really Jun 14 03:13:45 and romain's Jun 14 03:15:49 watching the first vid Jun 14 03:16:02 he added a param to his xml to have auto-animations Jun 14 03:16:10 but said it came in android 3.1 I think Jun 14 03:16:22 if I have that param in my xml will older devices just ignore it and things are still good? Jun 14 03:19:28 it'll ignore it and there'll be no animation Jun 14 03:19:34 perfect Jun 14 03:19:36 everything else will work the same Jun 14 03:20:21 what about if I did it programmatically instead of through the xml Jun 14 03:25:00 no Jun 14 03:25:01 that'll crash unless you're really careful Jun 14 03:25:39 so I can detect which versino of Android we are on and only use things that wouldn't crash Jun 14 03:25:44 but then it is a bit tricky in the code Jun 14 03:28:38 yeah Jun 14 03:29:08 http://stackoverflow.com/questions/3093365/how-can-i-check-the-system-version-of-android Jun 14 03:38:43 hello. I have a lengthy but important question. had answers, stating here to share and get different views. anyone wants to participate for 150 points bountry ? http://stackoverflow.com/questions/17005837/persistent-foreground-android-service-that-starts-by-ui-and-also-starts-at-boot Jun 14 03:44:17 hey guys, does anyone know how to decode the Base64 string under tag from Google Checkout API? Jun 14 03:54:02 I feel like there is probably some design guide somewhere for Android for specifically this thing I want to do Jun 14 03:54:06 just for this one little bit... Jun 14 03:54:18 want to have a list of available broadcasters that are live right now that you can watch Jun 14 03:54:24 it is sorted by number of viewers Jun 14 03:54:31 so the most popular broadcasters are on top Jun 14 03:55:05 I get the list by an http request that only gives me 50 at a time max, so I will probably have to request the total number, then request batches as people fling around Jun 14 03:55:26 fucking gradle.... Jun 14 03:55:36 then I don't know the appropriate design for refreshing or animating any changes like if someone disconnects... Jun 14 03:55:44 or if two broadcasters swap places Jun 14 03:55:52 not sure if the moving list would be helpful to users Jun 14 04:32:49 what solution would you guys suggest for a database on a phone that syncs both ways to a central server? Jun 14 04:36:49 hi android dev, i'm working on a custom input method for a languge that has 'x with caron' \u0078\u030c as a letter. i'd like to put it on the keyboard where 'z' is on the latinkeyboard. i'm working from the SoftKeyboard example files in the sdk. I'm having trouble correctly specifying the character and combining diacritic as the value of android:codes and in fact, the result looks wrong when i put the literal xcaron in the val Jun 14 04:37:21 specifically, i'm trying to customize the qwerty.xml file in the example project Jun 14 04:37:47 things were going finely until i encountered the problem of specifying combining diacritics. Jun 14 04:43:11 ok, stackoverflow has someone doing it this way here http://stackoverflow.com/questions/15417028/how-to-map-accented-characters-in-keyboard-xml, but is that standard? no one has upvoted the answer and in the question seems a bit neglected. Jun 14 04:45:53 i guess i have one other related question. if i have a particular ttf in assests, can i set a custom font on my Key elements? Jun 14 04:48:58 maybe on my first question, i want to override createKeyFromXml Jun 14 04:52:20 basically, i'm trying to figure out on the second question whether i can setTypeface on a Key or a KeyView, like I can on other Views Jun 14 04:55:01 am i in the wrong room? Jun 14 04:56:18 channel Jun 14 04:57:37 jcrowgey: you might be asking the wrong question, or asking at the wrong time of day Jun 14 04:59:36 Leeds, fair enough. I'm interested in a) how to specify unicode sequences (ie, a character and combining diacritics) as values for an input method and b) how to set a TypeFace on a custom input method. Jun 14 05:00:39 as to b, i've got no problem creating a TypeFace from a ttf file in assets/, and assigning it to a TextView using setTypeface(tf). but KeyboardView doesn't seem to have the setTypeFace method. Jun 14 05:00:39 yes, I get that Jun 14 05:00:59 well, let me know if you see how i can clarify in a helpful way. Jun 14 05:01:13 custom input methods aren't exactly common things for people to hack with - so it's a relatively obscure question to start with Jun 14 05:01:26 i agree about that. Jun 14 05:01:49 so a bunch of people could say "sorry, dunno about that" - or nobody could answer... same effect Jun 14 05:02:19 i see. well, i'll await any aha moments and post again if i learn more. Jun 14 05:12:26 Hey, how can I start an animation, after a fragment has loaded? Jun 14 05:21:02 hrmmm I just thumbed through the android design guidelines and didn't see any recommended way to handle this Jun 14 05:25:24 the facebook and twitter apps don't auto-refresh. They are pull-down-to-refresh Jun 14 05:25:39 so maybe that's the way I should do it...don't worry about animating items in and out as they change Jun 14 05:39:57 how can you stop an animation, at the end of each animation, while its on repeat? Jun 14 05:46:56 Hello, how do you share an sqlite database between activity? I wan't to set the specific row on a table in a different activity? Jun 14 05:47:45 androidnewb: you database class. init instance of that class in activities Jun 14 05:47:51 you have Jun 14 05:48:52 what do you mean? Jun 14 05:49:07 I can give you my source code Jun 14 05:49:12 no, thanks Jun 14 05:50:22 public class DatabaseClass extends SQLiteOpenHelper { Jun 14 05:50:24 i want to set other rows on table seperately do I have to opendatabase again or what? i have no clue Jun 14 05:51:21 DatabaseClass(Context context) { Jun 14 05:51:21 super(context, DATABASE_NAME, null, DATABASE_VERSION); Jun 14 05:52:38 yup I already did that, I can set my rows in my mainActivity, but when I switch to another activity it will create a new row, I wan't to continue setting the row as in my mainActivity Jun 14 05:53:03 in another activity you instantiate that class again Jun 14 05:53:30 but will that make a new row? Jun 14 05:53:54 it depends on the sql command you provide Jun 14 05:54:49 im using the getters and setters to set the values Jun 14 05:55:33 then it depends on sql command inside underlying implementation of these Jun 14 05:55:40 im using values.put I mean. Jun 14 05:56:36 im using just the values.put function that comes with the SDK Jun 14 05:56:55 "ContentValues" needs to be inserted Jun 14 05:56:58 will that make a new row? if I instantiate a new class in diff. activity? Jun 14 05:57:13 it depends on the sql command Jun 14 05:57:33 is this ContentValues a function? Jun 14 05:57:53 also how do you view the .db file in the android device? Jun 14 05:58:01 most of the time, Capitalized things are classes Jun 14 05:58:19 you may login to the device via shell Jun 14 05:58:36 linux shell? im using windows Jun 14 05:58:52 any shell, in windows: "telnet" Jun 14 05:58:58 anyways i'm screwed, keynote is tommrrow Jun 14 05:59:17 android simulator titlebar provides port clue for you Jun 14 05:59:55 I think I don't have much time to learn shellzz Jun 14 06:00:22 I just want to share sqlite database between activities Jun 14 06:00:45 adb -s emulator-5556 shell sqlite3 /data/data/my.company.name/databases/my_database_name "SELECT * FROM TABLE;" Jun 14 06:01:21 but i'm using the android device? Jun 14 06:01:42 I suppose device is protected Jun 14 06:02:02 they say it needs to be rooted first Jun 14 06:02:05 otherwise you could just grab all data off the phone Jun 14 06:02:28 if your app is debuggable you can use "run-as my.company.name" from adb shell Jun 14 06:02:39 for debug purposes you better use local database Jun 14 06:02:46 not android one Jun 14 06:03:05 like sqlfiddle.com websql Jun 14 06:03:45 ok, i will just use the emulator, but my only problem right now is sharing database between activities Jun 14 06:04:28 you use database class instance in activities Jun 14 06:05:17 ok, i look into that Jun 14 06:09:25 if anyone kind enough to save the day, I want to share sqlite database between my mainActivity and Begin.java, here my project code http://rapidgator.net/file/b3a405df2373e4f6fbac9d5dd9b9d555/Integra_two.rar.html Jun 14 06:19:40 hello. I have a lengthy but important question. had answers, stating here to share and get different views. anyone wants to participate for 150 points bountry ? http://stackoverflow.com/questions/17005837/persistent-foreground-android-service-that-starts-by-ui-and-also-starts-at-boot Jun 14 06:22:44 Sircle: is that task so important that you want it to start at boot? Jun 14 06:25:40 hi all, where might I start looking docs-wise if I wanted to create a PIN lock for my app (i.e. whenever it's closed and reopened, or switched back to, a PIN entry should appear before allowing the user to proceed) Jun 14 06:34:59 wow, i just fired up google earth for the first time in a couple of months... it can now 3d-ify all objects? Jun 14 06:35:29 it somehow has some kind of height-map algorithm that can detect heights of objects and render them in 3d instead of flat Jun 14 06:35:35 cars, trees, buildings Jun 14 06:35:38 * pragma- astounded. Jun 14 06:35:45 it does glitch sometimes Jun 14 06:37:07 i'm assuming the best place to put my hook to swap to the pin entry screen is in the lifecycle hooks Jun 14 06:41:29 would be really nice if we could sync our SMS/TXT with the cloud Jun 14 06:43:46 pragma-: this was introduced in google keynote 2013 Jun 14 06:44:25 Sircle, what could possibly be that important? If you mentioned what you're trying achieve, we might be able to suggest an easier way of doing what you want Jun 14 07:50:34 Hello Jun 14 07:51:04 Is it possible to rotate a whole RelativeLayout by 180 degrees? Jun 14 07:51:25 I found android:rotate, but apparently that's only supported in 3.0+, I want something that works at least in 2.2 Jun 14 07:54:17 argoneus: have you checked out http://nineoldandroids.com/ Jun 14 07:56:16 tnzr: will do, thanks Jun 14 08:05:16 hello. I have a lengthy but important question. had answers, stating here to share and get different views. anyone wants to participate for 150 points bountry ? http://stackoverflow.com/questions/17005837/persistent-foreground-android-service-that-starts-by-ui-and-also-starts-at-boot Jun 14 08:08:16 there seems no good reason to keep it running if you just need timer events Jun 14 08:19:53 Sircle, https://developer.android.com/reference/android/app/AlarmManager.html#setRepeating(int, long, long, android.app.PendingIntent) Jun 14 08:19:59 with ELAPSED_REALTIME_WAKEUP Jun 14 08:20:16 and a boot completed listener to set it off again after restart Jun 14 08:21:17 Sircle, https://developer.android.com/reference/android/app/AlarmManager.html#setRepeating(int,%20long,%20long,%20android.app.PendingIntent) Jun 14 08:21:43 bag, i hope your IRC client is cleverer than mine Jun 14 08:21:48 bah* Jun 14 08:30:14 in android studio, where do I find the google libraries such as 'google analytics' ? Jun 14 08:30:39 i mean, is there an "sdk manager" or so? Jun 14 08:31:55 spobat: Tools->Android->SDK Manager Jun 14 08:32:30 exactly what i was looking for, than you! Jun 14 08:32:41 it's also the second icon left to the ? on the toolbar Jun 14 08:33:25 iSee :) Jun 14 08:33:41 do many already use the android studio? Jun 14 08:33:50 It's also what you get when you type "android" in a terminal Jun 14 08:33:57 :) Jun 14 08:34:26 I'm relatively new. Started on eclipse, then gave android studio a try and droppped eclipse instantly Jun 14 08:35:03 :) Jun 14 08:36:31 what widget/view does NumberPicker use for drawing the numbers? Jun 14 08:38:26 nvm Jun 14 08:40:22 if you can tell me how I attach the just downloaded lib to the project that would be cool :p Jun 14 08:40:53 though, I believe it is *somewhere* in "Project Structure" Jun 14 08:41:20 You can toss it in libs/ Jun 14 08:41:24 Or add it through project structure Jun 14 08:41:58 I think in project structure you can add it to external libraries, but don't take my word for that Jun 14 08:42:56 ok Jun 14 08:43:18 for the support lib, the dev guide suggests putting it in libs/ in your project http://developer.android.com/tools/extras/support-library.html#SettingUp Jun 14 08:44:06 that worked, ty :) Jun 14 08:44:26 yay, I helped! Jun 14 08:44:36 * Achillion is giving back. Jun 14 08:44:42 Now, back to work Jun 14 08:59:37 any idea what is causing these errors with ABS ( ActionBarSherlock) ? Jun 14 08:59:39 https://dl.dropboxusercontent.com/u/6559846/Screen%20Shot%202013-06-14%20at%2010.58.32%20AM.png Jun 14 08:59:57 help, I'm using the new drawer layout and I want the list item which corresponds to the current screen to be selected (in blue, just like in the Drive app) and I cannot seem to find how to do that. I've tried setSelected and setChecked (which I learned later requires a CheckedTextView, and after seeing how those look I don't want to use them) Jun 14 09:00:01 I don't know what to do :( Jun 14 09:01:55 spobat: screenshot of the code and not the error isn't very helpful. Why not paste the errors in a pastebin? Jun 14 09:03:01 the error is visible at the bottom. Jun 14 09:03:05 will do, 1 second Jun 14 09:03:17 I want my InputMethodService subclass to run in a thread separate from the rest of the app Jun 14 09:03:32 spobat: well, it says the 2 packages don't exist Jun 14 09:03:47 shouldn't they come with ABS? Jun 14 09:03:54 * Achillion shrugs. Jun 14 09:03:57 I'm not familiar with them Jun 14 09:06:47 spobat: you either need to install them, or find out if they need to be explicitly pointed to Jun 14 09:06:54 I've registered an activity for a protocol using intent-filter in the manifest file. When I send an HTML E-Mail with an Link myscheme://foo/bar the E-Mail doesn't open my application. What could be the cause? Code: http://pastie.org/private/pkyju5orzkhmbgc8hml4lq Jun 14 09:11:34 memoryleak: does it open something? Jun 14 09:11:38 the browser e.g.? Jun 14 09:13:59 hmm Jun 14 09:16:22 timroes: yes, it opens the browser inline and says "Webpage not available" Jun 14 09:16:26 spobat, no, ABS does not come with junit :p Jun 14 09:16:41 timroes: The webpage at email:// might be temporarly.... Jun 14 09:16:45 memoryleak: does it try to open myappsxheme:// or just hello.com whatsoever Jun 14 09:17:09 because it might not detect that the scheme belongs to the url, if its a custom scheme Jun 14 09:17:19 and only link whats behind the scheme to a regular http url Jun 14 09:17:20 Zharf, what a pity ^^ Jun 14 09:19:39 timroes: trying now to open http://foobar/hello Jun 14 09:19:53 Hi! How to display "insert or edit" Contacts dialog? I succeed only with insert or pick. Jun 14 09:20:23 timroes: Ok, worked like that. Custom schemes are not recognized it seems. Jun 14 09:22:01 yeah but thats a bproblem with the mail app Jun 14 09:22:07 it just doesn't detect custom schemes Jun 14 09:22:19 in general you can use what you wanted to do, e.g. on your own page Jun 14 09:22:29 if you set everything works finde Jun 14 09:25:05 aren't custom schemes discoraged? Jun 14 09:25:36 you're meant to use a website that you can fall back on if your apps isn't present Jun 14 09:49:32 I'm confused about logcat usage. From documentation I thought adb logcat -f path/to/file would send logcat messages to filename. Why is this not working? I am actually interested in doing something like adb logcat -d -f path/to/file Jun 14 09:51:07 why not just redirect? Jun 14 09:51:34 Achillion, I know, but what exacly -f does then? Jun 14 09:52:05 I dont see -f as a logcat option in adb --help Jun 14 09:52:14 only as an option for adb backup Jun 14 09:53:04 and I just realised that "--help" does nothing Jun 14 09:53:05 but online docs suggest -f can be used with logcat: http://developer.android.com/tools/debugging/debugging-log.html Jun 14 09:53:40 hm Jun 14 09:53:48 It might mean that it only works in remote shell Jun 14 09:53:54 with the plain logcat command Jun 14 09:53:59 and not from remote Jun 14 09:55:53 Achillion, you are right! Jun 14 09:56:13 Cool. I love it when that happens :) Jun 14 10:42:58 anybody here familiar with testing content providers? Jun 14 10:43:09 specifically on how to provide a test database with preloaded data Jun 14 10:43:21 (without resorting to ugly hacks) Jun 14 10:49:04 hrnt you want to load a db from assests? Jun 14 10:49:18 lasserix: that would be nice Jun 14 10:49:30 http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/ Jun 14 10:49:41 note: the copy will exist parallel to the internal data of the app, Jun 14 10:49:49 so if you have a big one it'll be twice the space Jun 14 10:50:14 lasserix: yes, that would be the obvious way to open the db Jun 14 10:50:31 also: if you use a database over a certain size (can't remember off top of my head) you have to change the extension so the apk zip tool doesn't throw exception Jun 14 10:50:33 unfortunately it doesn't work here, because the context i get from ProviderTestCase2 does not give access to any asset Jun 14 10:50:48 so basically i can't use getAssets() Jun 14 10:51:11 you dont use getassests Jun 14 10:52:40 lasserix: the article you pasted calls myContext.getAssets() in copyDatabase Jun 14 10:53:28 doh Jun 14 10:53:31 im blind tonight Jun 14 10:53:33 can http post be used to get messages from devices and then use gcm http to send it to multiple devices? Jun 14 10:55:21 if you are using to test can't you just make a dummy app and enable exporting of the content provider? Jun 14 10:55:53 at the moment i am pasting the creation SQL to a java string literal Jun 14 10:55:55 which is pretty stupid Jun 14 10:56:02 considering that java heredoc support is... well :( Jun 14 10:57:28 i'd rather not change the actual application manifest just to work around this issue Jun 14 10:58:06 if you are just testing for now, you can always change it back Jun 14 11:04:12 hi guys. I have a question on WebView. does anyone here knows if I can use SSL Pinning with WebView? Is there a place I can define a custom trust manager or SSLContext object? Jun 14 11:06:57 Hello, I've got one problem with gradle, is there anyone who could help me? I'll be very thankful :) Jun 14 11:07:06 description of problem you can find here: http://stackoverflow.com/questions/17088203/how-to-convert-liveapi-project-into-gradle-project Jun 14 11:10:33 please, is here anyone who could help me, thanks :) Jun 14 11:16:43 hi Jun 14 11:17:12 hi Jun 14 11:18:18 is it possible to add button to PreferenceFragment? Jun 14 11:18:37 can http post be used to get messages from devices and then use gcm http to send it to multiple devices? Jun 14 11:18:43 i have this situation....app that shows prefs if this is first run Jun 14 11:19:18 now after choosing prefs i want to start it as service....how? Jun 14 12:24:28 anyone know a good float math library for android to do just vector math? Jun 14 12:25:19 what for? Jun 14 12:25:41 yeah, I'm gonna need some math stuff at some point too Jun 14 12:25:43 doing opengl stuff Jun 14 12:25:51 i will probably roll my own later Jun 14 12:26:02 but just wanted to forget about that for now and continue working on task at hand Jun 14 12:26:05 I found several linear algebra libs, but I dunno if I want to commit to a 3rd party lib Jun 14 12:26:19 yeah exactly, that's why just wanted something simple for now Jun 14 12:26:46 I'm aware of this http://math.nist.gov/javanumerics/jama/ Jun 14 12:26:49 best is to write your own from the start ... as you probably need to understand the calcs fully Jun 14 12:27:16 yeah yeah i can do that, i just wanted to get my camera up and running by breakfast so i can wow my friend :) Jun 14 12:27:48 lol Jun 14 12:28:01 plus i'm not sure i know how to write the most efficient methods to do such Jun 14 12:28:08 in java anyways so Jun 14 12:28:41 it's probably very application specific ;-) Jun 14 12:28:55 The org.apache.commons libraries I *would* rely on though Jun 14 12:28:59 they have some decent math stuff Jun 14 12:29:16 Hey there! Jun 14 12:29:19 yeah Jun 14 12:29:46 Is there a way to determine that the whole app (not just one activity) was in the background? Jun 14 12:30:53 I can only think of hackish ways like have each activity set a time in onStop and compare that time to the next one in onResume and if it's a short time it was the launch of another activity, if it's a longer time the app was in background. Jun 14 12:30:58 Is there a cleaner way to do this? Jun 14 12:31:34 unbert what is this for? Jun 14 12:32:50 For something un-userfriendly. The app should show a splash screen on start, but also if it wasn't shown for 24h. Jun 14 12:33:12 Currently, on a nexus 4, the app stays in RAM all the time so you never see the splash again (unless you quit it with back) Jun 14 12:33:41 So the new requirement is "If the app was in background and the user didn't see a splash screen in the last 24h, restart the app to show the splash". Jun 14 12:34:08 But all this onStart, onResume etc. is per activity, what I need is something for the whole app. Jun 14 12:34:48 won't restarting an app kill the already running process? Jun 14 12:34:48 you do know that splash screens are discouraged right? ;) Jun 14 12:35:02 Yes, I do, but the customer's customer doesn't. Jun 14 12:35:05 appel1: to be fair, he did state it's un-userfriendly Jun 14 12:35:05 Sirolf: no, it will reuse the process if already running Jun 14 12:35:09 I hate them as well. Jun 14 12:35:10 Achillion: true Jun 14 12:35:15 :) Jun 14 12:35:31 If i create an object in a static method, and return that object, that will create garbage right? I'm better off passing the object to return in the arg? Jun 14 12:35:32 Oh, there's a true restart app? :o) Jun 14 12:35:51 I have a BootstrapActivity at the bottom of my ActivityStack and I start that one with cleartop to reboot the app. Jun 14 12:36:18 of course, all of this has to work with Android 2.2 (API 8) ;) Jun 14 12:36:32 unbert could you use a service and broadcast an intent when on create and just check that the last on create >= 24 h? Jun 14 12:37:05 hello...I want to link and load a shared library with android ndk...I used PREBUILT_SHARED_LIBRARY and it links fine, but I get a RuntimeException when trying to run the app...Is it still not possible to load shared libraries without Java's System.loadLibrary? Jun 14 12:37:24 err use an interface for all of your activities (or better yet just use a base activity with the method) and then broadcast oncreate on destroy, see if they are equal then use that as your duration measure Jun 14 12:37:45 Yes, that's the plan I currently have. I was wondering if there's a better solutioin. Jun 14 12:37:55 But why broadcast? Jun 14 12:38:04 lasserix : why would it create garbage? Jun 14 12:38:27 All my activities already extend my own AspectActivity, so I was thinking of rebooting the app in AspectActivity.onResume if the conditions are right. Jun 14 12:38:53 Sirolf, that's what i was wondering: if in the method i have add() { vec3 v = new vec3(); return v; } then i'm creating it in there hence garbaage Jun 14 12:39:15 I guess i should ask, sorry for the noob question, is return new vec3 () any different from the above? Jun 14 12:39:46 not really Jun 14 12:39:47 lasserix: no Jun 14 12:40:21 ahh okay Jun 14 12:40:28 UnbertKant: funny how much development time is spent working around the defaults for how activities behave in Android :) Especially since for most users the default behavior is the expected behavior. Jun 14 12:40:53 then in that case eachcall is going to create a new instance of vec so i should pass the obj to return it Jun 14 12:41:09 if you just call the static method and no reference to the object it returned you'd probably be creating garbage ;) Jun 14 12:41:15 lasserix: I don't understand what that means :) Jun 14 12:42:01 if i have a for loop running a thousand times creating a new object each iteration (same as calling this method) it'll create garbage is what i mean Jun 14 12:42:13 ah Jun 14 12:42:22 depends on what you want to do Jun 14 12:42:25 lasserix: why would it, it'll create a new instance each time. Jun 14 12:42:37 you say you already have a vec on which you want some stuff done? Jun 14 12:42:50 like rotate it Jun 14 12:43:27 then fcourse just pass it as arg and have it returned after work done on it Jun 14 12:44:24 err what I'm wondering about is if i have myAddVector(vec a, vec b) { return new vec ( a.x + b.x, etc etc ) } it's going to be creating that return obj each time, so it's better to pass in the the result such as myAddVector(vec a, vec b, vec result) { result.x = a.x + b.x; etc; return result; } Jun 14 12:44:31 now no objects are being created Jun 14 12:44:40 just to do calculation Jun 14 12:45:15 yeah Jun 14 12:45:36 plus then i can do chained operations too :) Jun 14 12:46:46 lasserix: but what does this have to do with your "will it create garbage" question above? Jun 14 12:47:10 if i were to run this method a million times, it'll create garbage if i dont pass in the object to return Jun 14 12:47:33 basicly if an object has no reference left to it it becomes garbage right? Jun 14 12:47:47 from what i understand yeah, you can test it on and see on the DDMS Jun 14 12:48:02 lasserix: ah, you mean it'll create new objects that will get garbage collected when noone references them? Jun 14 12:48:08 percisely Jun 14 12:48:28 lasserix: I thought you were talking about producing garbage as in bogus data/corrupted memory. Jun 14 12:48:33 ahh Jun 14 12:48:34 lol Jun 14 12:48:43 but it doesnt really matter Jun 14 12:49:28 I mean Jun 14 12:49:37 depends on how you use the vector object fcourse ;-) Jun 14 12:50:43 with the honecomb drag and drop APIs has anyone gotten multitouch working? it seems that the motionevents just stop being sent Jun 14 12:50:56 best practice would probably be to have methods do exactly what you want them to do ... so if you just want an operation on an object ... make a static one with the objects as arg Jun 14 12:53:22 is there any better channel to ask ndk questions? Jun 14 12:54:09 nay Jun 14 12:59:17 Can anyone help me understand a fragment issue I'm having? I'm getting a crash in my Activity that uses a fragment on orientation change, and it's cooking my brain as to why this is happening. I do have code on github for reading...but on mobile so c&p is going to be painful. Jun 14 13:01:57 well, give the codez Jun 14 13:02:10 Stack trace is at http://pastebin.com/HHzDEmBf Jun 14 13:03:35 do you return any view in onCreateView() in your fragment? Jun 14 13:03:56 And code is at http://bit.ly/12tdzvj Jun 14 13:04:28 I do, look at the V1AlertDisplayFragment class Jun 14 13:04:59 My issue is that it looks like on orientation change, the inflater does nothing Jun 14 13:05:59 I do have different XML for the landscape and portrait layouts (also in the github repo) Jun 14 13:07:03 I'm also probably doing this all wrong, so if there's a smarter way, I'm open to suggestions as well. Jun 14 13:09:04 only difference is numCollums ? Jun 14 13:09:52 Yes. Jun 14 13:10:36 mmarker are you finding your old fragment?> Jun 14 13:11:12 so no matter in which orientation you start the app it works, and then crashes on orientation change? Jun 14 13:11:56 mmark are you using replace to swap your fragments in in code? Jun 14 13:12:10 Karlo|w: correct. As long as the orientation doesn't change, I get the correct fragment. As soon as I change, it crashes. Jun 14 13:13:26 inflate R.layout-land. ? Jun 14 13:13:42 lol Jun 14 13:14:12 nnarker you need to do this Jun 14 13:14:41 instead of .replace(R.id.fragment, fragment_ad) add a tag Jun 14 13:14:50 so like .replace(R.id.fragment, fragment_ad, tag_fragment_ad) Jun 14 13:14:51 then Jun 14 13:15:01 instead of instancing like this Jun 14 13:15:03 Fragment fragment_ad = new V1AlertDisplayFragment(); Jun 14 13:15:22 do Fragment fragment_ad = getSupportFragmentManager.findFragmentByTag(tag_fragment_ad) Jun 14 13:15:32 if (fragment_ad == null) { Fragment fragment_ad = new V1AlertDisplayFragment(); } Jun 14 13:15:36 and it should work Jun 14 13:16:08 i could be wrong ihad similar problem many moons ago Jun 14 13:16:46 there is no way to avoid Java's System.loadLibrary if I want to use shared libraries with android ndk? I'd like to have a pure C++ app... Jun 14 13:16:47 i can't remmeber now if that only applies to fragments added to the backstack or not Jun 14 13:19:30 That may work. Currently add the fragment through the onNavigationItemSelected using a beginTransaction/replace/commit type pattern (in V1Display class) Jun 14 13:20:04 So I was assuming Android would do the right thing automatically on orientation change. Jun 14 13:20:14 no never :) Jun 14 13:21:16 So, where would I stuff this code snippet of yours? Jun 14 13:21:27 just where you do the adding now Jun 14 13:21:37 just try and find it by the tag you replace it with Jun 14 13:21:43 if its null, then instance it Jun 14 13:22:07 this is operating on the presumption the fragment is just detached from the activity and then is waiting to be reattached Jun 14 13:22:14 on orientation change Jun 14 13:22:16 Ahh. Need to add tags to my 2 fragments in the XML then Jun 14 13:22:26 you can also use id Jun 14 13:22:27 Let me test it out Jun 14 13:23:05 the point is just to check if the fragmentmanager still holds a reference to the fragment swaped in before the orientation change, if so then rereference, if not instance Jun 14 13:24:21 how would one go about creating the footer that is on all the screens of the Play Music app? Jun 14 13:27:57 Hey all... I am having a «small» issue with an async task that downloads data from a server. Jun 14 13:28:26 good for you ;-) Jun 14 13:28:30 basilisk footer? Jun 14 13:28:40 I once had a <> one ;-) Jun 14 13:28:44 I try to .cancel(true) the task, but it's «stuck» waiting on HTTPUrlConnection.getResponseCode(). What's the «appropriate» way to cancel such? Jun 14 13:29:01 The server *WILL* take some time to respond. Jun 14 13:29:45 lasserix: the one that shows up when the music is playing Jun 14 13:29:49 hey Jun 14 13:30:22 Lachezar: do you set the timeout for url connection? Jun 14 13:30:24 I was hoping/expecting that the .getResponseCode() would throw an InterruptedIOException, but alas: no luck... Jun 14 13:30:41 basilisk: Yes, and it's significant (the server *WILL* take some time to answer). Jun 14 13:31:04 basilisk: I was expecting an InterruptedIOException, but I get none... Jun 14 13:31:37 Lachezar: why would you want to cancel that task? isn't it better to just let it finish in any case? Jun 14 13:31:42 yeah AsyncTask.cancel just sets cancel to true Jun 14 13:31:56 Sirolf: Nope! The owning activity has died... Jun 14 13:32:19 basilisk: Can I somehow 'Thread.interrupt()' an async task? Jun 14 13:32:55 you'll have to run a separate thread that monitors if the task has been cancelled Jun 14 13:33:00 (I guess) Jun 14 13:33:05 but the idea of async is that it's on its own thread right? Jun 14 13:33:48 basilisk: If I run a separate thread, I'd be easier keeping off AsyncTask! Jun 14 13:34:36
