**** BEGIN LOGGING AT Thu Jan 02 02:59:59 2014 Jan 02 03:00:35 <_genuser_> would you rather an activity does db work on it's own, or passes info back ot main activity and the main activity does the DB work? Jan 02 03:01:03 what kind of db work Jan 02 03:01:49 <_genuser_> creating one activity, so it can show newly retrieved list of items (from web), and existing list for a given group. Jan 02 03:02:10 <_genuser_> thinking of passing it the List in the intent before starting and it can change it and pass it back to MainActivity which can commit to DB. Jan 02 03:02:23 <_genuser_> this allows me to use the second activity as "add" and "edit" screen. Jan 02 03:02:51 you cant pass lists in an intent Jan 02 03:03:10 <_genuser_> I remember. I haven't quite figure that part out yet. Jan 02 03:03:12 <_genuser_> any ideas? Jan 02 03:03:58 <_genuser_> alternatvily, I could pass it the group ID, and second parameter indicating whether it should download the new data or fetch existing from DB for the user. Jan 02 03:04:12 <_genuser_> and then it could do it's own DB work. Jan 02 03:04:17 <_genuser_> *its. Jan 02 03:04:18 I'm trying to build the gstreamer tutorials, and in native_window.h I'm getting error:unknown type name int32_t Jan 02 03:04:34 I'm assuming I'm missing an include directory of some sort? Jan 02 03:20:39 hi all. I'm wanting to create an app that can identify 9 coloured squares of a rubiks cube using a devices camera. I'm wondering if anyone could point me in the right direction for resources and libraries etc. I have no prior experience with image analysis. Jan 02 03:21:23 (btw, I know apps like this exist already) Jan 02 03:21:57 Start reading up on opencv? That would probably be a good place to start. Jan 02 03:23:29 that looks very relevant. thankyou Jan 02 03:24:00 welcome :D Jan 02 03:34:47 hm, disabling gmail fixed my battery problem. Jan 02 03:35:49 g00s: not using an android device fixes my android device battery problems Jan 02 03:35:50 ;0 Jan 02 03:36:21 all of a sudden, beginning today, it started eating up the battery (25%) Jan 02 03:36:42 yeah, to have a good ux you need to disable everything :) Jan 02 03:41:01 <_genuser_> someitmes my phone will just drain battery fast. it's like something gets stuck. Jan 02 03:41:07 <_genuser_> a reboot usually fixes that tho. Jan 02 03:41:20 yeah, tried a reboot Jan 02 03:41:30 <_genuser_> also if you have auto scren brightness selected, instead of saving the battery it actually drains it super fast. Jan 02 03:41:49 <_genuser_> I know you already said it was gmail and it was fixed. just throwing out other culprits. Jan 02 03:42:24 is there a way to reset battery stats ? Jan 02 03:42:29 (without root) Jan 02 03:43:32 lame Jan 02 03:59:11 Hello, I'm deploying an app to my android device which is on the same network as my laptop, but when I try and make a network connection from the android device to my laptop I get a no route to host message Jan 02 03:59:40 Does anyone know how I can debug this problem, and make sure the network settings are correct so that my app on my android device can connect to my computer (I'm doing a client-server app) Jan 02 04:03:44 does it have the network permissions? is your laptop running any sort of firewall? Jan 02 04:04:35 dragorn: no firewall - it has the internet permission Jan 02 04:04:48 A firewall wouldn't return a "no route to host" message Jan 02 04:04:52 it would return a "connection refused" Jan 02 04:04:58 depends on how the firewall is configured Jan 02 04:05:09 well, not really Jan 02 04:05:11 No route to host means that it can't find the local IP Jan 02 04:05:17 so it wouldn't affect that message Jan 02 04:05:18 obviously you know more; good luck then Jan 02 04:06:22 (pro tip: a firewall that drops instead of rejects can definitely cause a no route to host since it effectively isn't present on the network and blackholes any traffic to it) Jan 02 04:07:00 Hello, sometimes when I run `gradle installDebug`, it hangs on the 'installDebug" task. A couple lines before it says "waiting until streams are handled...". What could be causing this hang? Jan 02 04:07:19 dragorn: yeah, I think you are right that it can send a different message than connection refused Jan 02 04:07:38 dragorn: but I think "no route to host" means the routing table doesn't have a route to the host, so it can't even attempt to start the connection Jan 02 04:07:45 Sometimes it works Jan 02 04:07:57 so maybe I'm doing something really bone-headed Jan 02 04:08:27 I just have a laptop running a server, an android device running an app, both on the same wifi network (and also connected via USB) Jan 02 04:09:51 cubahero: you'll get a NRTH when arp can't resolve, which could definitely be caused by a deny-all / drop-all firewall configuration. It's academic if a firewall isn't in play here. Sounds more like it doesn't have internet permission or you're mangling the IP and not talking to the right system. If it was me I'd throw a packet sniffer on the router and the laptop acting like a server and see if the packets are even egressing Jan 02 04:10:49 or your wifi doesn't allow inter-client communication (unlikely on a home AP, more likely on a college network or something, no idea what your situation is) Jan 02 04:13:09 dragorn: so, oddly enough Jan 02 04:13:13 I reran it and it worked Jan 02 04:13:17 with no changes... Jan 02 04:26:32 hey everyone Jan 02 04:26:51 it says no adveritsing, but im looking for some people to look at my android game and let me know if it looks pretty good for an android game Jan 02 04:26:57 is ther elike an android-dev social? Jan 02 04:31:22 Hello, i am developing a notepad-like app, a little bit more complex than the tutorial one though, and i wonder if i shall use a orm or write the database access by myself. Jan 02 04:31:28 I've been reading a lot Jan 02 04:31:34 but still in doubt.... Jan 02 04:31:40 any hint is very appreciated. Jan 02 04:42:12 well if anyones interested in a mobile multiplayer fps coop game Jan 02 05:00:04 tripknotix: nothing wrong with asking people to look at your app, I'd say Jan 02 05:01:21 well yeah but i didnt know if it was considered an advertisement, i just released it last monday so im looking for opinions , https://play.google.com/store/apps/details?id=net.RealDefinition.ZombieOpsOnline i mean if they dont get it then they only have screenshots to judge by really Jan 02 05:01:46 would love some feedback but i dunno if thats possible with just screenshots Jan 02 05:03:18 why no video? Jan 02 05:03:48 Hello, I'm wondering if anyone can help me out, or suggest how to go about solving an issue with UnsatisfiedLinkError. I'm getting the UnsatisfiedLinkError crash from specific devices, especially the Galaxy Note 8.0. What would you suggest to fix this problem? The UnsatisfiedLinkError does not show up in most of any other devices Jan 02 05:06:07 what library is missing ? Jan 02 05:07:46 tripknotix: also, your description is very basic... Jan 02 05:10:23 hey, is anybody running n AOSP-based rom on hammerhead here? Jan 02 05:11:08 something15525: does your app crash on that particular config or something? Jan 02 05:11:47 Leeds: no, i was more asking about a question about the camera Jan 02 05:11:52 specifically video recording Jan 02 05:12:01 anybody getting a green line down the left Jan 02 05:12:04 you have a camera app? Jan 02 05:12:05 and weird looking video? Jan 02 05:12:10 Leeds: no, the AOSP camera app Jan 02 05:12:14 this channel is for app development Jan 02 05:12:30 Leeds: oops, my bad Jan 02 05:15:29 <_genuser_> when one activity launches another with startActivityForResult, it listens for the result and reacts in onActivityResult, correct? Jan 02 05:17:54 I am confused about the android build tools. I have revision 19.0.1 installed, but here it says 0.7.0 was just released: https://android.googlesource.com/platform/tools/build/+/master/changelog.txt Which is it? Jan 02 05:18:13 bricker`LA actually 0.7.3 was just released Jan 02 05:18:29 And how do I install the latest? It keeps telling me Gradle 1.8 is required, but 0.7.0 says Gradle 1.9 is required. Jan 02 05:18:37 That's the android gradle plugin, not build tools Jan 02 05:19:06 SimonVT: oh - how do I install this? Jan 02 05:19:41 I see this http://tools.android.com/tech-docs/new-build-system/user-guide but there are no instructions on installation that I can find Jan 02 05:19:52 You don't install it Jan 02 05:19:57 It's pulled from maven central Jan 02 05:20:10 ohhhhhh Jan 02 05:20:42 SimonVT: now I understand what "'com.android.tools.build:gradle:0.6.3+'" that I copied and pasted actually means Jan 02 05:20:54 SimonVT: can you tell, I've been developing android apps for about 2 days :P Jan 02 05:24:05 ^_^ Jan 02 05:24:24 ahhhh, so much better, thank you! Jan 02 05:33:17 Leeds: are videos that important for games? Jan 02 05:33:33 tripknotix: somewhere between essential and must-have, I'd say Jan 02 05:34:27 o i c... Jan 02 05:34:42 hmmm Jan 02 05:35:09 start a whole franchise and make the movie + sequels ! Jan 02 05:37:44 Now how do I tell `gradle installDebug` to run on a running emulator? Jan 02 05:41:18 hit the bug Jan 02 05:45:48 anyone know of a way to enumerate only the user-imported entries of the certificate store ? Jan 02 05:57:30 finally android studio can import eclipse projects Jan 02 06:00:49 not very well apparently Jan 02 06:01:44 Hello, does anyone know if calling handleMessage inside the override of a subclassed handler call directly, or does it go on message stack? Jan 02 06:02:17 Eeeeeee hasnt it been able to since day one? Jan 02 06:02:23 I know intellij in general could Jan 02 06:02:31 nope Jan 02 06:02:38 Leeds: any recommended screen capture software or is fraps good enough? Jan 02 06:02:41 had to import to eclipse then export Jan 02 06:03:03 tripknotix: I think I'd be looking to use the built-in recording now Jan 02 06:03:04 hey ron_frown Jan 02 06:03:10 it wasn Jan 02 06:03:19 t able to convert to gradle before Jan 02 06:03:21 yo Jan 02 06:03:26 hohoho Jan 02 06:03:46 I say we invent more shit to solve more problems that dont exist Jan 02 06:03:51 thats the java engineer mindset Jan 02 06:04:38 well, i think you had to export eclipse adt project into some gradle thingy first, and then import into AS = i think they made it so AS imports directly now Jan 02 06:04:59 and then reorganize folders Jan 02 06:05:01 ron_frown: with more XML Jan 02 06:05:01 the thing I'm sarcastically referring to is of course gradle Jan 02 06:05:03 it's broken for me Jan 02 06:05:06 always more XML Jan 02 06:05:08 Leeds PRECISELY! Jan 02 06:05:27 put json in your xml .. solved ! Jan 02 06:05:31 I wish java would do the honarable tihng, and just go the fuck away Jan 02 06:05:36 just like its cousin product oracle Jan 02 06:05:40 just go the fuck away Jan 02 06:05:46 lol Jan 02 06:06:03 java can be written decent, but typical usage promotes terrible shit Jan 02 06:06:19 right now, i'm working with one of the most horrendous APIs in existence … JSSE … an abomination Jan 02 06:06:23 what they try to integrate into the newer versions is amazingly shitty Jan 02 06:07:05 hey, don't lump Java in with Oracle Jan 02 06:07:14 ron_frown did you hear about that M# thing from MS ? Jan 02 06:07:22 java and oracle are both shit Jan 02 06:07:27 I deal with oracle on a daily basis Jan 02 06:07:33 worst fucking rdbms I've ever used Jan 02 06:07:38 and I've dealt with mysql etc Jan 02 06:08:28 I do rather enjoy oracle announcing new features that litereally every remotely mainstream rdbms has has for 10+ years Jan 02 06:08:40 ahhaaha Jan 02 06:08:40 and touting it like its amazing new functionality Jan 02 06:09:00 that's what Apple does Jan 02 06:09:05 oracle just needs to do the right thing and perform seppuku publically Jan 02 06:09:46 you can hype it if you follow through Jan 02 06:10:25 I like how to seemingly competitive products like oracle and mysql can be so vastly different Jan 02 06:10:28 er Jan 02 06:10:29 mssql Jan 02 06:10:42 mssql can basically run undetected in low usage environments Jan 02 06:10:52 oracle will rape the fuck out of your machine, no matter what its doing Jan 02 06:11:08 oh well Jan 02 06:11:11 enough of that rant Jan 02 06:12:16 what build in recording leeds? Jan 02 06:12:50 http://developer.android.com/tools/help/adb.html#screenrecord etc Jan 02 06:13:03 g00s: Caused by: java.lang.UnsatisfiedLinkError: Couldn't load opvpnutil from loader Jan 02 06:13:34 dck28 are you providing that ? i didn't think android came with openvpn Jan 02 06:13:46 i'm providing it Jan 02 06:14:01 man I dont want to fuck with javascript, but I am gonna need it Jan 02 06:14:24 dck28 hopefully more info in the logcat Jan 02 06:14:25 if web is ever going to be mainstream, google/others better get browsers performing better on mobile devices Jan 02 06:14:40 mainstream as a replacement to a native app Jan 02 06:14:47 g00s: thing is... it works fine for most devices... only a few models are giving me trouble on this.. Jan 02 06:15:00 see the devices are just getting faster Jan 02 06:15:09 eventually the issues will just go away Jan 02 06:15:43 ron_frown the web served its purpose for google; now its all about their megaplatforms Jan 02 06:15:52 internet connected for sure, but open, meh Jan 02 06:16:08 I dont know Jan 02 06:16:10 and fb, etc Jan 02 06:16:22 they are shooting to do stuff like open standard dart Jan 02 06:16:31 dart is significantly faster than javascript vm Jan 02 06:16:44 whether it'll take off is another thing Jan 02 06:16:49 but it shows good intentions Jan 02 06:17:27 good intentions of what exactly :) Jan 02 06:17:43 making the web a better place Jan 02 06:17:55 I think people ar too afraid to shake shit up Jan 02 06:18:02 decision makers are a bunch of pussies Jan 02 06:18:14 the fact that javascript is still the standard web scripting environment Jan 02 06:18:30 it fucking sucks therefore anything that compiles to it, is going to fucking suck at best Jan 02 06:18:41 just gut it. Jan 02 06:19:16 transitive theory of sucking shit Jan 02 06:19:50 i didn't get the impression dart was going anywhere Jan 02 06:20:04 well everyone wants their own shit to take off Jan 02 06:20:31 mozilla basically doesnt want to play nice with anyone... they are touting asm.js which is a micro subset of js that they then optimize the shit out of Jan 02 06:20:34 probably candidate for spring cleaning :) Jan 02 06:20:45 but js is still js Jan 02 06:20:56 people think the new ecmascript is gonna be the fixer Jan 02 06:21:37 I dont really get the recent excitement with js... its slow, its actually not easier to write good code with than a real programming language Jan 02 06:21:56 its obfuscated at best, half assed module loading, no real multi-threading Jan 02 06:22:25 hello i am using configchanges to prevent activity destruction on rotation, etc. However I need to write some state to sqlite tables between activity instances. They say to use onPause but this would be overkill, since I really only need to write to the tables when the activity is going to be destroyed. Is there no other method I can use reliably (since onStop / onDestroy not garunteed to be called?) Jan 02 06:22:42 g00s make your big bucks yet? Jan 02 06:23:36 eh, never looking to make big bucks - just find interesting things to work on ;) Jan 02 06:24:26 hahah Jan 02 06:24:28 yeah I hear you Jan 02 06:25:01 my nosql db? 80%, my craigslist replacement... 90% Jan 02 06:25:11 my projects are interesting but unfinished Jan 02 06:25:14 collecting dust =) Jan 02 06:26:05 Weird, the Table 2 http://developer.android.com/guide/topics/sensors/sensors_overview.html#sensors-intro shows that Android 4.0 supports the TYPE_GRAVITY sensor. My 4.1.2 android tablet returns null for mSensorManager.getDefaultSensor(Sensor.TYPE_GRAVITY) Jan 02 06:26:37 ron_frown maybe you'll like this gigaom.com/2013/12/14/5-predictions-on-the-future-of-databases-from-a-guy-who-knows-databases/ Jan 02 06:27:32 I agree with a lot of those points Jan 02 06:27:53 I think rdbms's introduce a lot of retarded artificial constraints on stuff that they shouldnt Jan 02 06:27:59 however... Jan 02 06:28:05 nosql hasnt been done right Jan 02 06:28:16 gotta be some sort of hybrid Jan 02 06:28:26 and def about coming back to earth Jan 02 06:30:05 I havent created many databases, but I've examined the source of many, as a hobby Jan 02 06:30:58 lasserix why not onSaveInstanceState Jan 02 06:30:58 I've got 20yr doing db shit... and will be the first one to tell you I think enforcing constraints etc is bs... babysitting devs Jan 02 06:31:12 and sprocs ultimately negatively outweihg their benefits Jan 02 06:31:18 controversial opinions, I know Jan 02 06:32:31 g00s save instance state is called when onpause is called? Jan 02 06:33:41 g00s I have to save a couple thousand long arraylists Jan 02 06:33:47 Guys, if I have BOSCH BMC150 Acceleration sensor, am I supposed to have a gravity sensor? Jan 02 06:34:11 serializing those would (just assuming here) be slower than writing to a sqlite db? Jan 02 06:34:45 lasserix did you see Activity doc "Saving Persistent State" Jan 02 06:35:41 heh "mozilla basically doesnt want to play nice with anyone" :p Jan 02 06:35:43 yeah Jan 02 06:35:51 well normally i would just write it off in onPause Jan 02 06:36:10 but since the activity uses config changes, that would be more than i need to do, since I only really need to when the activity is destroyed Jan 02 06:36:49 i was thinking i could completly do away with even the sqlite tables by using onRetainNonConfigurationInstance Jan 02 06:37:09 Guys, I have an accelerometer Jan 02 06:37:32 Does that thing work as a gravity sensor? Jan 02 06:37:39 but even then it looks like i have to handle the application being destroyed Jan 02 06:37:41 lasserix i thought that was deprecated Jan 02 06:37:46 ohh Jan 02 06:38:00 maybe it is, never used it just thought i could avoid even the writing time to sqlite table Jan 02 06:39:11 ahh so if the activity is destroyed the retained fragment will still have the data? Jan 02 06:39:46 i think so; kinda forgetting Jan 02 06:41:48 It survives configuration changes Jan 02 06:41:58 only config changes Jan 02 06:42:01 that's already handled Jan 02 06:42:26 i need to persist data between activity instances (with config changes on for orientation, etc) Jan 02 06:42:46 however since the writing to the tables can take 60 seconds i didn't want to put it into onpause Jan 02 06:42:57 :O Jan 02 06:42:58 but instead only in onstop (preferably) but someone mentioned that does not always get called Jan 02 06:43:08 yeah catch 22 .. Jan 02 06:43:23 lasserix wut kind of data is this :P Jan 02 06:43:32 lots and lots and lots of strings Jan 02 06:44:15 for instance, 40k strings of the form "1111~2" Jan 02 06:44:50 but i guess if generating them on activity recreated is faster than saving and reloading them might as well just requery Jan 02 06:44:54 hmm Jan 02 06:45:07 form of 1111~2 ? Jan 02 06:45:16 yeah that's pid ~ version Jan 02 06:45:19 something seems crazy here ;) Jan 02 06:45:33 its for content observers on content providers Jan 02 06:45:45 O.O Jan 02 06:46:01 <.< Jan 02 06:46:04 >.> Jan 02 06:46:05 heh Jan 02 06:46:40 i managed to reduce query time from 180 seconds to 20 seconds expanding from 92 to 5000 records but that didn't satisify the higher ups ;! Jan 02 06:46:52 yeah no crap :) Jan 02 06:47:31 so what are all these entries again ? Jan 02 06:47:42 splain moar Jan 02 06:47:45 contact data Jan 02 06:48:08 Are you stealing user data? Jan 02 06:48:12 haha no Jan 02 06:48:18 I think you are Jan 02 06:48:44 if i were stealing it i wouldn't have to keep it current Jan 02 06:48:45 Anyway.. Save your data as it changes Jan 02 06:49:03 i am exploring android build system, i have a question. Example application is Calculator. I see the folder in packages/app/Calculator/Android.mk file, but this "Calculator" is not captured in the core.mk @ build/target/product/Core.mk Jan 02 06:49:19 yeah i had that working but it was causing 40s lag time which was not acceptable by higher ups Jan 02 06:49:28 could someone help me ? Jan 02 06:49:39 hence the catch22 problem of how to deal with when/where to save Jan 02 06:49:48 40s lag time? Jan 02 06:50:10 yeah if i write a table of 40k row entries, i have to read that too Jan 02 06:50:31 so i am switching to using in memory hashmaps, but istill need to keep this data around between activity instances Jan 02 06:50:43 How does that cause lag Jan 02 06:51:40 underlying architecture is not double buffered yet Jan 02 06:52:34 Define lag Jan 02 06:53:02 so far i was being niave and writing to the table as the data changes, Jan 02 06:53:42 but since this took 40s per change (and the changes are throttled) read operatings had to wait Jan 02 06:53:52 *operations Jan 02 06:53:55 for the writing to finish Jan 02 06:54:39 so i am refactoring it now simulating double buffering of the architecture i have to work with, but i kinda assumed calling a 40s sqlite table write everytime onpause was called was also no good Jan 02 06:54:50 So basically all 40k entries are changed every time Jan 02 06:55:03 no Jan 02 06:55:13 but the first time Jan 02 06:55:23 is what the higher ups care about Jan 02 06:55:41 One insert wouldn't take 40s.. A delete wouldn't take 40s.. I see no reason you can't save data as it changes Jan 02 06:56:33 i am moving to that now by using in run time memory data structures Jan 02 06:56:50 none of this is making any sense to me Jan 02 06:57:09 hmm Jan 02 06:57:45 i see your point simonvt, i was hoping to move all sqlite executions outside of the running of the app (ie in onpause) so that it will run (even) faster Jan 02 06:58:29 As for the first time, does querying the data take 40s? Jan 02 06:58:36 yeah Jan 02 06:58:57 well Jan 02 06:58:57 Not with your current implementation Jan 02 06:58:59 20 seconds Jan 02 06:59:02 The actual data you're getting Jan 02 06:59:05 yeah Jan 02 06:59:07 20 seconds Jan 02 06:59:09 Where are you querying it from? Jan 02 06:59:14 rawcontacts Jan 02 06:59:42 And it doesn't take 20 seconds when querying from your apps db? Jan 02 07:00:01 no cause for the content observer i just grab the pid and the dataversion Jan 02 07:00:39 the bottleneck with rawcontacts is (a) no table joins (b) the two dozen or so columns of data per entry Jan 02 07:00:56 (no table joins with tables not in the content provider) Jan 02 07:01:29 i was going to run it in a service Jan 02 07:01:45 but decided that would be determintal to battery life (possibly) Jan 02 07:02:47 anyways thanks for checking me, maybe i am just making it more complicated than it needs to be Jan 02 07:07:09 lasserix maybe you want to start from scratch and explain what you are trying to do. all i got was you had 40k of thingies and its taking too long Jan 02 07:10:40 i have to keep a list of "current state" for the content observer to distinguish what changed from some content providers. for security and speed, current state is usually the pid and the dataversion Jan 02 07:10:48 *for some Jan 02 07:11:01 sometimes this is a list can have 40k entries Jan 02 07:11:39 i need this list between activity instances, Jan 02 07:11:52 the activity uses configchanges for orientation etc Jan 02 07:11:56 god damn it Jan 02 07:11:59 so where to call and how to save this list Jan 02 07:12:00 ELI5 !' Jan 02 07:12:17 pretend i'm your manager, i dont give a fuck about your content observer Jan 02 07:12:25 WHAT ARE YOU TRYING TO DO Jan 02 07:12:44 quickly save a very very large list of strings between activity instances Jan 02 07:13:03 * g00s headdesk Jan 02 07:13:10 as simonvt pointed out, technically this should be easy once i initially write the list Jan 02 07:13:25 40k of anything is not easy on android Jan 02 07:13:30 haha Jan 02 07:13:57 if only the bags under my eyes and lack of vacation really showed through ;p Jan 02 07:14:06 what content observers? what state? Jan 02 07:14:09 why ! Jan 02 07:14:23 in this case its contacts and its for use in the app Jan 02 07:14:36 so you have 40k contacts ? Jan 02 07:14:54 no but rawcontacts.entities contains a dozen or so rows per unique contact Jan 02 07:15:08 ohh, k Jan 02 07:15:15 and while my implementation was working for "normal" people my boss has 5k contacts Jan 02 07:15:33 it would work well for me too ;) Jan 02 07:16:05 yeah, like i said the previous dev took 180 seconds to do just 100 contacts, i got up to 5k in 20 but they were like not good enough! Jan 02 07:16:36 though i have learned exponetially about java so i am happy :) Jan 02 07:17:00 anyways, i recall from my niave days of making my previous apps that serialization on this many strings is slow Jan 02 07:17:04 so you are trying to monitor a change in any entity of any contact ? Jan 02 07:17:12 yeah Jan 02 07:17:27 and when there is a change, then what do you care ? Jan 02 07:17:40 i need to know the change and the app needs to reflect that change Jan 02 07:18:58 "reflect that change" sounds like you are copying state though Jan 02 07:20:16 probably being as specific i can be :/ Jan 02 07:21:43 hmm Jan 02 07:22:33 i dont know much about the Contacts provider Jan 02 07:22:46 newer android versions will give you the URI that changed in the observer Jan 02 07:22:54 so lame, should have been there since API1 Jan 02 07:23:02 what dumbass made that decision ... Jan 02 07:23:04 dont assume cursor.isNull(index) is ever telling the truth! Jan 02 07:23:20 having a problem as well Jan 02 07:23:34 but if its a directory that changed, you can't really know which records Jan 02 07:23:39 its all stupid crap Jan 02 07:23:42 with fragments/contentprovider Jan 02 07:23:44 g00s i was under the impression that was just a directory uri Jan 02 07:24:00 is the new content observer also uri specific? Jan 02 07:24:06 *item uri specific Jan 02 07:24:19 ya Jan 02 07:24:30 http://developer.android.com/reference/android/database/ContentObserver.html#onChange%28boolean,%20android.net.Uri%29 Jan 02 07:24:32 eeeeee what's up? Jan 02 07:24:46 how new? 4.4? Jan 02 07:24:49 hey Jan 02 07:25:05 hmmm Jan 02 07:27:16 uri specificity seems inconsistent Jan 02 07:28:19 but thanks that seems it could be useful! Jan 02 07:34:14 as for databases seems like someone should use a genetic algorithm to develop the best database architecture Jan 02 07:34:54 works for antaneas and human relationships, why not databases? Jan 02 07:42:05 in this answer: http://stackoverflow.com/questions/4255859/touch-and-drag-image-in-android. onDraw() is called basically every tick of the thread, is this an acceptable way to do it or is it acceptable? Jan 02 07:42:59 lasserix what would the fitness criteria for "best" be ? Jan 02 07:43:14 onDraw() redraws a bitmap inside it Jan 02 07:43:27 fitness function for an antenna are simply s/n and sensitivity Jan 02 07:44:04 I am familiar with android widget spinner, but I want to place an icon/image on the screen and when tapped, it opens a list which originates from the point where it was tapped. I dont think spinner is the correct widget, any suggestions on the correct widget? Jan 02 07:44:41 *i mean is it an inefficient way to do it or is it acceptable Jan 02 07:48:09 no one? Jan 02 07:48:42 arcode: typically games shoot for 16 ms refresh rate, if you are doing something simple 20-30 will work fine Jan 02 07:49:03 ok thanks lasserix Jan 02 07:49:36 look at eshayne's comment Jan 02 07:49:41 if that applies use that Jan 02 07:49:59 zquad: i saw something that might be of some use in the action bar documentation Jan 02 07:50:02 because forcing a redraw every 1ms or 16ms or even 32 ms is a relative battery drain than only when needed Jan 02 07:50:09 i don't have his comment in chat history Jan 02 07:50:39 thanks se_busca_ayuda checking it out Jan 02 07:50:58 zquad: look under adding an action provider Jan 02 07:51:06 g00s: i dunno human tolerance for work to output ratio is not easy to measure Jan 02 07:51:07 lasserix: i thought it was resource heavy, i will try changing it to redraw only when the bitmap has moved Jan 02 07:51:29 arcode: good idea, you're app won't show up as draining battery then :) Jan 02 07:52:21 zquad there are several ways you could do that, but i think there is like pop up menu or something to do that the trick is positioning its display Jan 02 07:53:42 Hi is it possible to rotate a custom rendered map in Android WebView using the Gyroscope values ? Jan 02 07:54:23 thanks lasserix it called a popup menu, doesn't seen to work with anything < 11 though :(, my minimum sdk is 8 Jan 02 07:55:38 ubuntufreak: i would imagine so. you just have to use the output of the gyroscope like a matrix Jan 02 07:56:06 how does one navigate to a top level activity from a deeper level one using the side bar? the CLEAR_TOP flag wont do since there are multiple top level activities Jan 02 07:56:29 rhcake: did you try getActivity()? Jan 02 07:56:45 se_busca_ayuda: you mean pass the values to WebView and handle the rotation there using JS ? Jan 02 07:57:13 se_busca_ayuda pardon? Jan 02 07:57:14 ubuntufreak: why wouldn't you just use the java matrix package? Jan 02 07:57:25 rhcake: oh i misunderstood your question, sorry Jan 02 07:58:30 se_busca_ayuda: need to check that, are there any leads for that ? Jan 02 07:59:10 ubuntufreak: your linear algebra textbook from your CS undergrad :) Jan 02 07:59:40 ubuntufreak, http://developer.android.com/reference/android/view/animation/RotateAnimation.html Jan 02 07:59:50 one can apply rotation animations to views Jan 02 08:00:24 se_busca_ayuda: ah will find it then : ) Jan 02 08:01:55 PatrickBic: Thanks will check it Jan 02 08:02:44 PatrickBic: But the problem is that the rotation data needs to send to server and based on that map needs to be rendered. I feel it takes too much bandwidth in a mobile Jan 02 08:05:31 sorry was on the phone... Jan 02 08:05:49 ubuntufreak, you want a rotation like 47° ? Jan 02 08:06:48 if yes, sending a value/few values to the server is like ... nothing compared to the real data Jan 02 08:07:37 PatrickBic: Yep it's something similar to how the Google Maps render based on the direction the user moves Jan 02 08:08:01 well yea, shouldnt matter at all (sending this sensor-values) to the server Jan 02 08:08:06 after all it will be a few bytes Jan 02 08:08:59 PatrickBic: Ok would try that out Jan 02 08:14:23 <_genuser_> guys, I have a non-main activity which will show a listview with items. can click on them to edit/remove or add new. when done, this activity closes and the results need to be reflected back to the main. Jan 02 08:14:41 <_genuser_> should this activity do all the db modification and then just close leaving the main to refresh? Jan 02 08:14:54 <_genuser_> or should it pass data back to teh main which will updatd the db? Jan 02 08:15:17 <_genuser_> I'm split on what is the best approach. curious what others do in similar situation. Jan 02 08:16:52 i would go for saving stuff in the non-main-activity (with a shared db-class ofc). seems like a self-contained way of doing it Jan 02 08:17:36 <_genuser_> I see. should I pass teh db object reference to it? Or let it instantiate a new one and on notification to the main let it re-read from db? Jan 02 08:18:14 zquad there is a lower level pop up dialog or something i used to use Jan 02 08:18:33 lasserix... go on... Jan 02 08:18:51 i would go for re-reading from db because it doesnt need you to write more code (you have that code @startup already) and the time/performance penalty shouldnt be that big/hard Jan 02 08:19:35 <_genuser_> PatrickBic: nah, time performance would be minimal because this is something where I wouldn't expect more than 50 rows max. if the user was craaaaaazy in adding stuff. 10-15 max. Jan 02 08:19:56 yea i said "shouldnt be big" :P Jan 02 08:20:12 <_genuser_> PatrickBic: right, that was my agreement. got lost in text only communication. :) Jan 02 08:20:17 :P Jan 02 08:20:54 i would go for re-reading => clean state, won't be that much slower, each activity is like.. an unit by itself Jan 02 08:20:55 <_genuser_> I have designed this 3 times already in my mind. just can't seem to find the right balance in "automagic" and simplicity. Jan 02 08:20:58 How can I access Activity's menu from Fragment? Jan 02 08:22:01 <_genuser_> Pitel_IPEX: you're already created the menu and added to activity but want to access it runtime? Jan 02 08:22:08 _genuser_, well.. there are tons of patterns for every purpose :P Jan 02 08:22:35 _genuser_: Yup, I just want to change MenuItem's visibility. Jan 02 08:23:30 Hmm, even the Activity doesn't seem to have anything like getMenu() or something. Jan 02 08:23:35 <_genuser_> PatrickBic: main use, add a class, and each class has sections under it. Main interface has a nav drawer showing classes and sections under them but tabbed over. Jan 02 08:24:12 <_genuser_> PatrickBic: so I want to add a screen that will add class info, and show a listview where you can add more by hitting a plus which will launch a add_section activity. Jan 02 08:24:34 <_genuser_> PatrickBic: BUT, there's also a possibility that a provider will have a json file available that can be just downloaded, parsed and added. Jan 02 08:25:03 <_genuser_> PatrickBic: and I thought it would be nice to download the json file, parse, add, and then show them the same info in the edit screen so they can tinker with it before moving away from it. Jan 02 08:25:43 <_genuser_> PatrickBic: and originally I didn't want to add it to the db until they finish tinkering and give the final go ahead. But doing it that way forces to pass around List where E is serializable and just a kludge of crap passing between activities. :) Jan 02 08:26:11 do you instantiate the other activities from one main activity, right? Jan 02 08:26:23 why not keep a public variable ? ;-) Jan 02 08:26:23 <[E]sc> i'm trying to learn how to program in android, is this the proper channel to discuss that topic? Jan 02 08:26:32 <_genuser_> Pitel_IPEX: one approach: http://stackoverflow.com/questions/10579333/how-can-i-get-the-options-menu-of-my-activity Jan 02 08:27:15 <_genuser_> PatrickBic: make the main activity has a public var and just access it all over from other activities? Jan 02 08:27:24 <_genuser_> *have Jan 02 08:27:25 yep Jan 02 08:27:40
