**** BEGIN LOGGING AT Sat Feb 20 02:59:58 2016 Feb 20 03:16:01 RustyShackleford: dpm Feb 20 03:16:26 oops nvm Feb 20 03:21:11 Don't ping me? Feb 20 03:23:28 I feel like throwing a party every time my code Just Works. Feb 20 03:25:55 I'm trying to use an emulator, but it is very very slow. I'm on a Mac Mini and in the Run section it says "HAXM is working and emulator runs in fast virtual mode". If that's fast, I'd hate to see a slow one. It took four minutes too boot. A click on an icon might provoke a response 30 secs later. Feb 20 03:26:48 kinch: What are the specs of your machine? Feb 20 03:27:44 nothing to brag about. 2.66 Ghz Core 2 Duo, 8GB Feb 20 03:29:54 current ones are probably twice a fast. Still, that would not make the emulator much more useable. There must be something wrong. Feb 20 03:30:44 any pointers on how to build this?: https://android.googlesource.com/platform/packages/apps/DeskClock/ Feb 20 03:33:35 the cpu in the AVD manager is set to X86 so it's not because it's emulating an ARM Feb 20 03:34:58 J’s on ma feet Feb 20 03:35:00 so get like me Feb 20 03:37:03 kinch: Hmm, not sure. I wonder whether it helps to use an older image, though (such as the Nexus S). I've found that to be quite a bit faster than the Nexus 5 image. Feb 20 03:38:05 I'm on an i5 with 12GB RAM, and the emulator is fast. I'm using only 5GB RAM right now, though, with it and AS (and other stuff) open. Feb 20 03:39:56 Is 13 inch small to be working with Android Studio ? Feb 20 03:40:04 Is 13 inch MBP small to be working with Android Studio ? Feb 20 03:40:15 during install of android studio there was a question of memory usage, don't remember precisely the purpose. I chose the default of 2GB. Perhaps that was the memory allocated to the emulator Feb 20 03:40:36 suhas_sm: get a cheap external screen, your future self will thank you. Feb 20 03:40:45 hmm Feb 20 03:41:31 But I am next to a actual desk. Feb 20 03:41:37 But I am hardly next to a actual desk. Feb 20 03:42:21 when will the first parallel universe cpu be invented? Feb 20 03:43:12 lets say I don't get myself external screen, would I find the screen size small for android studio ? Feb 20 03:44:44 suhas_sm: Probably best to try a 13" screen in the store. Feb 20 03:45:06 Along with the external monitor, I will have to buy a desk and chair too :P Feb 20 03:45:07 Though that won't answer every question (unless you can somehow install Android Studio on there). Feb 20 03:45:45 Will install it on a friends MBP and check it out Feb 20 03:46:25 Personally, I would suspect that a 13" screen will be too small for programming. Feb 20 03:47:20 15 inch is damn good. But the one I use right now is provided by company I work for. it won't be with me forever Feb 20 03:48:41 You could always buy a Windows laptop at a way lower price. :D Feb 20 03:48:50 win32 sux Feb 20 03:48:51 Noooo :( Feb 20 03:48:53 15.6" Windows laptops are inexpensive. Feb 20 03:49:03 I am loving this experience now Feb 20 03:49:10 This MBP has spoilt me Feb 20 03:49:11 win32 api is antiquated Feb 20 03:49:24 shit just hasent evolved since like xp Feb 20 03:49:45 layered windows are a joke Feb 20 03:49:46 I would rather switch to linux Feb 20 03:49:57 dont even get me started on x11 Feb 20 03:50:04 makes me wanna punch nerd faces Feb 20 03:50:06 the XPS 15 is nice for 2 G's Feb 20 03:50:22 just get a chromebook everything gonna be web soon anyways Feb 20 03:50:28 hmm Feb 20 03:50:33 i run x11 - its ok Feb 20 03:50:59 Windows sucks, but so does Mac OS. And so does GNU/Linux. Feb 20 03:51:10 (And Android.) Feb 20 03:51:33 yeah, everything sucks as soon as you know it well enough Feb 20 03:51:47 I'm not sure I buy the idea that Mac OS is better than Windows. Feb 20 03:52:04 depends who you ask Feb 20 03:52:18 pointless to argue about it though Feb 20 03:52:57 i could from the standpoint that its a *nix. i'd rather run stuff on OSX if it was just osx and win32. Feb 20 03:53:07 So, I think we've decided: suhas_sm is getting a Windows laptop. Feb 20 03:53:21 :| Feb 20 03:54:40 I doubt that will ever happen now Feb 20 03:55:01 Mac has spoilt me Feb 20 03:58:26 I have 2 MacBook pro retinas on my desk Feb 20 03:58:39 I like Windows much more by far Feb 20 03:59:13 I do like Mac hardware, though. Feb 20 04:00:57 jdv79, download all of aosp, then make DeskClock, done Feb 20 04:01:28 thanks Feb 20 04:02:29 none of the aosp apps build standalone Feb 20 04:02:38 they all make use of framework internals Feb 20 04:14:34 thing i like about OS X these days is that it has some awesome apps like Affinity Designer Feb 20 04:15:17 does anyone work with android apps without android studio? Feb 20 04:16:16 iirc going the IDE-less route in the java world is a pita. Feb 20 04:22:17 jdv79: If they do, they're crazy. Feb 20 04:24:31 idk. i guess i'm old. when i use an ide i feel like i'm forced into weird mindsets i don't appreciate. Feb 20 04:25:01 like a windows admin poking around trying to find the magic incantations Feb 20 04:25:18 i get it for layout but not otherwise Feb 20 04:25:38 was just curious if anyone had any experience going sans IDE Feb 20 04:25:55 jdv79: I did it a bit, but I agree. it's a PITA Feb 20 04:26:06 * Ping_2_Ur_Pong loves an IDE, coding in vim can be productive if you're used to it, but auto-complete is beautiful, text highlighting is beautiful let's not even start on auto-indentation Feb 20 04:26:20 IDEs offer powerful code completion and code navigation. That's much harder to get with a (dumb) text editor. Feb 20 04:26:24 i don't need any of that personally Feb 20 04:26:33 Also debugger integration. Feb 20 04:26:48 the completion i can see since the lib collections are so large Feb 20 04:26:51 You don't need code completion and navigation? Feb 20 04:26:52 maybe Feb 20 04:27:10 not really. idk. Feb 20 04:27:22 jdv79: you can do your straight java without an ide, but building out your UI will be really hard without sometype of way to view your xml. I think it would be more work than it is worth than to just use the IDE. Feb 20 04:27:26 unix is my ide:) Feb 20 04:27:27 it would be an interesting thing to try Feb 20 04:27:51 yeah, layout/ui stuff. sure. Feb 20 04:28:21 you must be a grep/sed/awk king Feb 20 04:28:25 so i'll take this as a "no, nobody does or doesn't want to talk about it' Feb 20 04:28:32 Working without code completion and code navigation would restrict the best of the best, let alone everyone else. Feb 20 04:28:34 idk. i'm ok. Feb 20 04:28:52 to each his own i say Feb 20 04:28:54 autocomplete XML resources is ... essential imho Feb 20 04:29:26 I'm an awk/sed/grep king and even I would never write code for the JVM without an IDE. Feb 20 04:29:47 ive never tried it, im sure you could do it. Feb 20 04:29:48 I remember years ago when code completion was absent (or less good). The sheer amount of typing you had to do was insane. And the amount of looking up stuff in documentation. Feb 20 04:29:53 http://developer.android.com/tools/building/building-cmdline.html jdv79 Feb 20 04:29:55 Just those two activities were a huge time-sink. Feb 20 04:30:02 why dedicate working capacity to memorizing methods / etc when you could use it on the problem domain at hand Feb 20 04:30:06 i admint my java experience is very limited. i've coded c# stuff without VS before. Feb 20 04:30:12 *admit Feb 20 04:30:15 The same applies to C#. Feb 20 04:31:12 * Ping_2_Ur_Pong generally has a rule about not remembering stuff he can easily look up. Unless its one of those use really often and you remember it by sheer usage. Feb 20 04:31:39 i don't remember a lot of stuff. that's what docs are for, no? Feb 20 04:31:49 * Ping_2_Ur_Pong nods Feb 20 04:31:52 That's what code-completion is for. :) Feb 20 04:31:58 Ping_2_Ur_Pong thats good, because as the brain gets older it has more trouble clearing out irrelevant stuff :P Feb 20 04:32:03 And Ctrl+B or Middle Click. Feb 20 04:32:04 * Ping_2_Ur_Pong was going to say that 2 secs later Feb 20 04:32:24 Or Ctrl+P ("show parameters"). Feb 20 04:32:29 ok Feb 20 04:32:36 that does that in AS TacticalJoke ? Feb 20 04:32:57 I write java and jvm targeted code without an ide all the time Feb 20 04:33:12 less often now that intellij is so awesome though Feb 20 04:33:14 I'm sorry, jdv79, but your request not to use Android Studio has been denied. Feb 20 04:33:40 seems so Feb 20 04:33:41 ide xml preview is useless though Feb 20 04:33:43 I'm just kidding, BTW. Sometimes, text sounds blunt as heck. Feb 20 04:34:02 that is the least reason to use android studio Feb 20 04:34:04 pfn every once in a while ill do some something quick in java that I run straight from the command line and don't open the IDE for, but its usually less than 30 lines. Feb 20 04:34:10 jdv79: I think some people use vim with some kind of Android-code-completion stuff, but I've never tried it, and I can't imagine it's that amazing. Feb 20 04:35:06 emacs has a good java completion mode, I think Feb 20 04:35:11 and ensime is amazinf Feb 20 04:35:15 I was creating a Java "Hello, world" using plain vim on a Raspberry Pi the other day. Gawd, it was a pain without IDE stuff. Feb 20 04:35:26 Even typing the import statements was obnoxious. Feb 20 04:35:37 its no big deal. i'm just trying to do some android stuff and there's alot. AS is just my scapegoat at the moment cause its in my face and its very busy. Feb 20 04:35:46 we'll see in a few days if i can't get something working Feb 20 04:36:06 and ironically slow as shit Feb 20 04:36:20 busy as in the UI/complexity is what i meant Feb 20 04:37:01 jdv79: Yeah, the default UI setup is too busy. I hide most of those things. Feb 20 04:37:02 well, not ironic. just oddly. though i imagine that shouldn't be surpising. Feb 20 04:37:18 anyway, bleh. Feb 20 04:37:20 You don't even need a file navigator in IntelliJ. Ctrl+N (and Ctrl+Shift+N) is generally enough. Feb 20 04:37:46 Try View > Enter Distraction Free Mode for the kinda thing I mean. Feb 20 04:38:04 Although you don't have to use Distraction Free Mode to get a simple view. Feb 20 04:52:46 Tactical I didn't know about distraction free mode, that's friggin great, I absolutely love it, tnx Feb 20 04:53:14 g00s: would you know how to use reflection to instantiate an @hide interface / listener, and defining its callback ? Feb 20 04:53:40 * capella googling furiously Feb 20 04:53:58 why isn't my fragment visible? Feb 20 04:54:27 RustyShackleford: that is a very vague question Feb 20 04:54:29 onCreateView {return inflater.inflate(R.layout.content_main, container);} Feb 20 04:55:04 theres also an optional 3rd paramter attachToRoot Feb 20 04:57:10 I dunno i'm confused Feb 20 04:58:05 bah ... too much of ViewTreeObserver is @hide ... particularly interface OnComputeInternalInsetsListener Feb 20 04:58:21 anyone have any good android dev blogs, podcasts? Ive been listening to Android Developer Backstage, looking for more that are technical and not 30 mins of cheesy jokes and 2 mins of technical details. Feb 20 05:00:09 RustyShackleford: Doesn't every tutorial use `inflater.inflate(whatever, container, false);`? :s Feb 20 05:00:55 yeah seems to be a pattern Feb 20 05:01:08 if I omit it, does it default to false? Feb 20 05:02:49 RustyShackleford: https://android.googlesource.com/platform/frameworks/base.git/+/master/core/java/android/view/LayoutInflater.java#374 Feb 20 05:04:01 awesome Feb 20 05:04:11 would have been cool if they put that in the docs Feb 20 05:04:18 didn't think to look in the source Feb 20 05:04:47 * capella all hail the source Feb 20 05:04:50 On a side note, has the online documentation changed appearance? All of a sudden, the "Returns" thing is hard not to notice. Feb 20 05:04:58 In fact, it's hard to notice anything else. :s Feb 20 05:05:15 its commented there Feb 20 05:05:25 I don't see it on this page Feb 20 05:05:35 I mean the documentation pages. Feb 20 05:05:54 oh god I'm blind Feb 20 05:06:07 maybe thats enough android development for today Feb 20 05:08:11 so i did repo sync and that was an hour ago Feb 20 05:08:24 what is happening... Feb 20 05:12:03 I wish the Java world used `enabled` and `setEnabled` naming (rather than `isEnabled` or `getFoo` or whatever). Would be much clearer. Feb 20 05:12:12 There's really no need for a prefix on the accessor. Feb 20 05:12:49 `print(person.name());` and `person.setName("Sam");`. Though first-class properties are better, of course. Feb 20 05:12:54 anyone know how big this "aosp" is? Feb 20 05:12:58 its at 11G so far Feb 20 05:13:04 what the hell is in there?! Feb 20 05:13:14 It's the Android Open Source Project. It's gonna be big. Feb 20 05:13:20 i hope some movies Feb 20 05:14:07 yah, there's movies in there :p Feb 20 05:14:41 maybe i should have seen if repo does shallow clones Feb 20 05:14:43 :( Feb 20 05:17:49 yo we gotta this loot on shit boomin in here Feb 20 05:23:21 I wonder how long it takes to compile android Feb 20 05:23:48 4-core w/SSD? Or quantum device? Feb 20 05:24:33 4 core with SSD sounds reasonable Feb 20 05:25:12 this guy says 270mins http://www.droidforums.net/threads/want-to-know-how-long-it-takes-to-finish-compiling-an-aosp-rom.109422/ Feb 20 05:30:40 wow 270 Feb 20 05:30:55 will the build fail on the 270th minute ?-) Feb 20 05:32:03 Android can provide a welcome workflow activity? Feb 20 05:32:08 such a common usecase?? Feb 20 05:33:19 are tabs supported in 6? Feb 20 05:45:02 does romain guy still come here? Feb 20 05:46:14 the website says i need 100G of disk to build the aosp stuff Feb 20 05:46:22 i do not have htat much disk. jesus. Feb 20 05:46:43 i guess i'm out Feb 20 05:49:02 The suggested cache size is 50-100G Feb 20 05:49:54 well, repo sync is still chugging and its up to 25G now. i'll give it 50G and then i'm killing it. Feb 20 05:50:03 what is this world coming to Feb 20 05:50:33 you have an external hdd? Feb 20 05:50:51 if so mount it and write directly to it. Feb 20 05:50:53 i do. but that's kinda slow usb. Feb 20 05:51:02 like shit it is Feb 20 05:51:02 i'm doing local ssd at the moment Feb 20 05:51:26 usb 3.0 is faster than you can download and usb 2.0 should be able to keep up with your download speed Feb 20 05:51:33 usb2 Feb 20 05:52:02 maybe i'll try that once this way fails. Feb 20 05:52:32 * Ping_2_Ur_Pong had to transfer 50 gigs from one an old computer so he scp it over the network but wrote it directly to his hdd. using usb2.0 took 4ish hours but it still worked and was painless Feb 20 05:52:50 oh wow. it completed at 33G Feb 20 05:52:54 nice Feb 20 05:53:33 that is still a shitload of space, I kind of want to build the android source, ive always been curious at looking and working with the source, just really never had any need to. Feb 20 05:53:40 why have you decided to jdv? Feb 20 05:53:58 i just want to build a modified version of their alarmclock/deskclock app Feb 20 05:54:07 and pfn told me its easy to do it in situ Feb 20 05:54:14 so i'm gonna try that tomorrow Feb 20 05:55:29 hmm... Feb 20 05:55:30 yeah. i have never seen anything use up that much space. _maybe_ a few gigs. seems like insanity to me. Feb 20 05:55:58 i mean it is the source to the entire OS. 33 gigs isn't bad tbh Feb 20 05:56:50 https://android.googlesource.com/platform/packages/apps/AlarmClock/ Feb 20 05:57:01 uh i guess. i think linux is a few gigs. Feb 20 05:57:01 wy not just grab that git and build that? Feb 20 05:57:10 i did and it failed and i couldn't figure it out Feb 20 05:57:16 then pfn said to try this way Feb 20 05:57:20 :) Feb 20 05:57:25 * Ping_2_Ur_Pong nods Feb 20 05:58:03 its weird though, should work... The core apps are intended to be very modular. Feb 20 05:58:57 * Ping_2_Ur_Pong thinks he is going to try to build the alarm clock app just to futz with the code Feb 20 06:01:12 int dayCount = 0; Feb 20 06:01:15 for (; dayCount < 7; dayCount++) {yes Feb 20 06:01:18 that's weird Feb 20 06:01:31 UI Design is hard Feb 20 06:01:38 they remove the intialization of the dayCount outside the for loop Feb 20 06:01:55 my actionbar is drawn on top of my main view Feb 20 06:02:43 http://pastebin.com/c2mtGtCW Feb 20 06:02:56 RustyShackleford: UI design is all thinking like an old codgy woman that hates everything, if you can think of anything that the old lady that bitches about everythig would dislike then reconsider it. Feb 20 06:03:26 this was autogenerated by AS, I added the framelayout Feb 20 06:05:09 your actionbutton is supposed to be on top of your main view. It hovers over your view. Is the placement wrong? A picture is worth a 1000 words. Feb 20 06:05:37 I added padding so my textview is visible Feb 20 06:05:58 its just a placeholder, but the actionbar covers part of that framelayout Feb 20 06:06:13 I want a "container" that I can change dynamically Feb 20 06:06:30 i.e. the FrameLayout Feb 20 06:09:15 http://developer.android.com/reference/android/widget/Space.html ? Feb 20 06:10:41 eh no I don't think so Feb 20 06:10:51 Do I need a CoordinatorLayout? Feb 20 06:11:09 A relativeLayout would be an easy fix Feb 20 06:38:32 pretty plain vanilla question: i want to use a rest webserver, what's the best way to go about doing that? Feb 20 06:39:46 also, I'm using the java.time libraries for the server; anything I can do to conver the dates into that format from android? Feb 20 06:39:54 kommunicate: can you explain? are you asking "whats the best way in Android to communicate and use a rest server?" or "how do i make a rest server for use with Android?" Feb 20 06:39:57 jsr310 seemed to cause build failures when i was trying it before Feb 20 06:40:29 Napalm: I want to communicate with a rest server Feb 20 06:40:44 isn't there a http client lib somewhere? Feb 20 06:40:57 kommunicate: https://square.github.io/retrofit/ Feb 20 06:40:57 Look at Retrofit Feb 20 06:41:00 seems like there's a lot of alternatives, i just want to know which one you like the most Feb 20 06:41:38 this looks good Feb 20 06:42:14 kommunicate: the converters you use decides how the data-format over http is serialized and deserialized into java objects Feb 20 06:42:17 kommunicate: https://github.com/square/retrofit/tree/master/retrofit-converters Feb 20 06:42:31 so you can use xml, json, protobufs.. whatever Feb 20 06:42:38 hell make your own :| Feb 20 06:43:18 I'd like to spend the minimum amount of time shuffling from one data format to another Feb 20 06:43:20 NO! after what seems like an hour the build failed:( Feb 20 06:43:36 off :( Feb 20 06:44:10 i hear json is what the cool kids use these days Feb 20 06:44:41 soap 4 evar Feb 20 06:44:45 lol Feb 20 06:45:27 * jdv79 cringes Feb 20 06:45:37 whatever floats your boat Feb 20 06:45:46 Wanna hear a joke? The "S" in SOAP stands for "Simple". Feb 20 06:45:57 :) Feb 20 06:46:01 aggh Feb 20 06:46:23 painful to remember Feb 20 06:47:00 you guys ever had to consume java8 dates? Feb 20 06:47:33 i'm not sure if i have any alternative except to hack up the server side Feb 20 06:49:27 do I need to subclass my own recyclerview? Feb 20 06:49:33 I want a listview basically Feb 20 06:49:44 RustyShackleford then use listview :P Feb 20 06:49:52 but I want to learn the fancy new API Feb 20 06:51:03 RustyShackleford: why do you want to subclass it? Feb 20 06:54:15 kommunicate: trying to figure out how to use it Feb 20 06:54:42 you subclass listview pretty often. Looks like I don't need to subclass recyclerview Feb 20 06:55:05 do you guys use CoordinatorLayout? Feb 20 07:01:39 Is it worth using a lib to encrypt SharedPreferences (specifically for an API auth token)? It seems pointless since it's still stored locally and can be accessed by anyone with root Feb 20 07:03:20 well if it"s encrypted it doesn"t matter if they can access it Feb 20 07:25:12 y’all nerds know what it is Feb 20 07:49:21 Hi. Is there any way how to change the TabLayout indicator's width? Feb 20 07:54:09 just the indicator or the whole tab? Feb 20 07:55:06 afaik the indicator takes the same with as the tab Feb 20 07:55:34 width* Feb 20 07:58:20 orbyt_: just the indicator Feb 20 09:20:37 liuwenhao: depends. Do you want to protect against a child trying to extract the token? Then it is useful. Do you want to protect against a compsci student or someone working for a competing company trying to extract the token? Then it's useless Feb 20 09:21:07 Because you'll have to decrypt it to use it, and in that moment one can do a memory dump. Feb 20 09:34:29 Hi, I have a recyclerview of images, and a detail view of those, which uses a viewpager, the viewpager is going to be in a fragment. How can I sync scroll in recycler and swiping in viewpager, ie, if user swipes 20 images in pager and presses back, the recycler should show the same image at top that was last visible to user in viewpager Feb 20 09:49:50 astroduck: well, you could use start activity for result instead of start activity, and then let the detail activity return, as result, the ID of the image scrolled to? Feb 20 09:50:07 Another clean solution would be via a service to sync them. Feb 20 09:50:23 In either way, you'd then just do a scroll to position at that moment Feb 20 09:51:41 justjanne: How does photos app do it? Their recycler and detail view are synced perfectly Feb 20 09:52:01 Also, does activity goes in onStop when fragment is attached? on onPause? Feb 20 09:52:20 *or onPause Feb 20 10:10:33 oh, so you have two fragments? Feb 20 10:10:59 you do realize that you can do many different ways then, considering that you instantiate the fragments yourself? Feb 20 10:48:13 justjanne: like? attaching a listener to fragment? or maybe firing an event, I am using eventbus in my app Feb 20 10:48:37 your choice – you have a direct reference to the fragment, you can just do these things Feb 20 10:50:57 I think I'll just use eventbus, simple 3 lines of code :P Feb 20 12:19:09 people Feb 20 12:19:45 coordinatorlayout shows views on big screen in wrong order Feb 20 12:19:59 why& Feb 20 12:20:00 ? Feb 20 12:22:50 Hey.. I'm trying to fix "plugin with id 'com.android.model.application' does not exist" in my gradel build does anyone know what this means, google seems to fall down with this. Feb 20 12:24:32 change it to com.android.application Feb 20 12:25:39 baash05: that is from experimental gradle, what jvrodrigues said should help you if you use standard gradle Feb 20 12:27:16 Yeah.. but I'm trying to get a native app running and this is from the sample. Feb 20 12:27:33 sorry native activity. Feb 20 12:28:59 Is it safe to pass reference of activity to adapter of recyclerview in that activity? Feb 20 12:29:38 I'll drop it back to stable :( Just wish the sample creators picked stable eh :) Feb 20 12:32:01 Anyone know of a sample native-activity other than the one in samples? Feb 20 12:34:30 mbarisa: and jvrodrigues: thanks heaps Feb 20 12:36:28 what do you mean native activity? Feb 20 12:37:22 There's a sample in the NDK that is called native activity.. Feb 20 12:37:28 it has no java at all. Feb 20 12:37:41 but the sample use the fun experimental gradel Feb 20 12:38:01 And getting it to work on a new project is undocumented. Feb 20 12:38:06 aah Feb 20 12:38:07 or well I can't find the docs. Feb 20 12:38:14 cant help you there sorry Feb 20 12:38:33 Yeah.. it's was a long shot. Feb 20 12:39:19 You'd figure the samples would be replicatable.. :) Feb 20 12:39:40 If I wanted easy I'd be a web programmer :) Feb 20 12:39:49 ahahaha Feb 20 12:40:30 that comment has the potential to make a lot of people mad Feb 20 12:40:30 Only funny because I'm a ruby-on-rails dev in my day job :D well and because its web dev.. Ha Feb 20 12:41:00 in web developers defense, I couldnt center a div if my life depended on it Feb 20 12:41:21 mad respect for those guys who center divs for us Feb 20 12:41:30 Ha ha.. Feb 20 12:43:22 You do any NDK work? Feb 20 12:44:50 nah, im a java developer Feb 20 12:44:54 mostly android Feb 20 12:45:18 some backend aswell, java, php, js Feb 20 12:47:29 hm does anyone know of a validation framework for android? I have read about making my own, but I don't want to re-invent the wheel unless I have to.. I tried https://github.com/ragunathjawahar/android-saripaar, but my widgets are defined in a layout.. and I'd like to attach validators there Feb 20 12:48:42 also centering a div is relatively easy (even vertically - though that depends on the target browser), but I am afraid I wouldn't be able to do it at the first try even though I like CSS and know my way around it Feb 20 12:55:47 baash05: what is your gradle version? Feb 20 12:57:41 baash05: classpath 'com.android.tools.build:gradle-experimental:0.2.1' Feb 20 12:57:47 try that Feb 20 12:58:27 with for me com.android/model.application works with it Feb 20 13:08:23 hi all, what is the best/most common practice for uniquely identifying and caching information from MediaStore? I'm developing an app in which i run an algo upon every image in MediaStore. should I query mediastore in onCreate every single time my app starts in case the user moved some photos around, or if there is a way to "sync" mediastore with my local Feb 20 13:08:23 data every so often. right now all I know is that _ID only persists for the duration of a "session" and that some people use the absolute /emulated/ path returned by .DATA since that is persistent and handle the rest manually. Feb 20 13:26:30 mbarisa: Thanks.. I got it working.. I think.. No gradle errors at least. Feb 20 13:26:50 I really just wanted to know that my android_main was being called. Feb 20 13:31:39 people Feb 20 13:43:47 appbarlayout covers all other views in API > 16 Feb 20 13:43:49 ^( Feb 20 13:43:55 what could it be? Feb 20 13:43:59 and why? Feb 20 13:46:36 actually i have two phones 4.4.2 - work as expected Feb 20 13:46:38 and 5 Feb 20 13:46:49 5.1 - appbar covers all other views Feb 20 13:49:29 can someone help me understand why jarsigner & zipalign shows GOOD results but when installing the app i get "App not installed" ????? Feb 20 13:49:58 the debug apk works great btw Feb 20 13:50:08 (crosswalk) Feb 20 14:07:55 nodedfree, whats the error you get Feb 20 14:37:07 people i found out - it was elevation Feb 20 14:50:15 danijoo_: fixed the error, after removing previous debug app Feb 20 14:52:42 you cant the same app installed twice ;) Feb 20 16:12:59 what is the advantage of using one of the frameworks resource identifier? Feb 20 16:13:11 i.e. android:id/list instead of +id/list Feb 20 16:23:27 ListFragment will automatically assign android:id/list for getAdapter() and getListView() Feb 20 16:35:25 are there other reasons? Feb 20 16:35:39 no Feb 20 16:38:33 ListFragments are so last week Feb 20 16:39:17 even last week they were unpopular :p Feb 20 16:41:22 jvrodrigues sometimes, you need to use android:list or some arbitrarily defined ID. for example, you want to provide a custom layout for PreferenceFragment. You can use whatever you want, as long as it has a ListView with android:id/list ... PF must find it in the hierarchy Feb 20 16:43:11 ah, ofc, make sense yea Feb 20 16:43:31 wonder why I didnt think of that Feb 20 16:43:56 maybe because its a terrible way to go at it Feb 20 17:10:50 crap PreferenceFragmentCompat assumes its not a child fragment and calls through to the parent activity to handle screen click. And PreferenceFragmentCompat#getCallbackFragment is public, but hidden Feb 20 17:10:57 kinda like they didn't think things through Feb 20 17:21:11 more like no one cares about nested fragments Feb 20 17:32:46 hm weird I have never thought of this before, but if I write a class that is generic (e.g. SomeClass), is it possible to have a private attribute this type? from what I currently see all I can do is either use T or View (according to my example) Feb 20 17:33:05 private attribute of this type* Feb 20 17:41:22 Can someone explain why in the Retrieiving Data section for Firebase docs, they use a ValueEventListener? Why isn't there a method for retrieving the data without one? Feb 20 17:41:43 Aoi: What do you mean by "private attribute"? Feb 20 17:42:28 I was just curious why it is not possible to write "private view" or something.. Feb 20 17:42:59 I never dealt with such a thing before so I was wondering if there is a way Feb 20 17:43:08 But what is there to make private? The type parameter is visible only to those who can see the class or method or whatever. Feb 20 17:43:33 I did not mean the class definition Feb 20 17:43:39 but the attribute(s) Feb 20 17:44:30 You mean that you want a field of the T type? You can just say `private T t;`. Feb 20 17:45:13 so T also considers the class I extend from? Feb 20 17:45:36 ah lol.. must have a brain cell jumping in my head.. Feb 20 17:47:04 The `extends Foo` part doesn't need to be repeated as it's just a restriction for the type parameter. Feb 20 17:48:26 yeah so the T I use inside my abstract class implies that extension already Feb 20 17:52:04 Is there a way in Android studio to automatically override a layout to specify a different version in landscape mode? Feb 20 17:53:53 hrmf Feb 20 17:54:03 Plast_, http://developer.android.com/training/basics/supporting-devices/screens.html Feb 20 17:54:05 Is Google really selling tickets for I/O like two weeks before event? -_- Feb 20 17:54:49 adq my question was if Android Studio had automatic support for doing that? You know how it will override a layout if you use an API feature above your minSDK Feb 20 17:55:22 Android Studio won't do a thing. It's a code edit.r Feb 20 17:55:30 Mavrik guess it makes it more fun to plan your itinerary :) Feb 20 17:55:38 g00s, eh Feb 20 17:55:54 Just annoyed because it gets expensive and hard to plan. Feb 20 17:56:09 when you rightclick on res and select "new res directorty" Feb 20 17:56:12 Suits me for not paying 4000$ of rent in SF I guess. Feb 20 17:56:43 you can ask AS to add portrait layout folder for example Feb 20 17:57:03 Plast_, might wanna look at guides a bit: https://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources Feb 20 17:57:24 There's a list of resource qualifiers. Feb 20 17:58:33 oh I didn't even see that you can add qualifiers to layout resource directories. Thanks adq Feb 20 18:04:56 weird.. I think I have a design flaw in my head... if I have say a EditTextValidator, which inherits methods common to all Validators (e.g. "validate()") from AbstractValidator, how am I going to keep a "String message" in the class if I might need to override it in a subclass of EditTextValidator? Feb 20 18:07:57 I'm going to make a list item view for my recycler view Feb 20 18:08:33 how would you determite how tall this view is? wrap_content? or specify a value in dp Feb 20 18:09:02 you can use ?listPreferredItemHeight or similar Feb 20 18:10:03 Aoi: It's hard to tell what you're asking. Those terms you're using are very vague. Feb 20 18:11:43 they are very precise to me :) Feb 20 18:12:05 but don't mind it I guess I solved it.. not sure I solved it the best way, but it was the best way I could think of Feb 20 18:12:33 You're talking about a "message" and "overriding" that in a subclass. That could mean anything. Feb 20 18:13:11 hello everybody Feb 20 18:13:18 well overriding is clear, but message was supposed to be a "string" instead Feb 20 18:13:50 basically say I have a protected attribute in Class A and B is a subclass of A.. yet I'd need to override that attribute - what would be the best way to do it?` Feb 20 18:15:00 the reason I'd like to have attribute in Class A is because I'd like methods that will be common to all subclasses of Class A be defined in there (in Class A) Feb 20 18:15:40 I'm guessing that, by "attribute", you mean "field" once again. Feb 20 18:15:50 object attribute Feb 20 18:16:38 object is an instance of a class.. object attribute is the attribute that has the object scope - at least that's what they are called in German Feb 20 18:16:48
