**** BEGIN LOGGING AT Tue Mar 08 02:59:59 2016 Mar 08 03:03:07 django_: You have to add a listView xml element. In that bpaste code, it only shows a FrameLayout and textView. Mar 08 03:26:07 rxjava makes my brain hurt Mar 08 03:26:46 lol Mar 08 03:27:53 why Mar 08 03:28:14 Observable getPain() :D Mar 08 03:28:40 RustyShackleford it has a steep learning curve for most people Mar 08 03:29:21 the coursera functional reactive course makes the learning curve next to nil Mar 08 03:30:29 "We assume you know the fundamentals of functional programming and the Scala language." Mar 08 03:30:41 oh well Mar 08 03:30:47 eh, the functional programming course is good, too Mar 08 03:30:55 coursera progfun course Mar 08 03:31:05 but the functional reactive c ourse isn't hard Mar 08 03:32:27 they link to this https://www.manning.com/books/reactive-design-patterns Mar 08 03:32:37 "Although most of the book's examples use the Scala language, no prior experience with Scala or Akka is required." Mar 08 03:32:42 i wonder how they do that then Mar 08 03:33:06 they use words to describe what's going on Mar 08 03:33:08 I suppose Mar 08 03:34:43 I've done a little functional programming... no scala Mar 08 03:34:55 the simple examples are easy. I'm struggling with how to elaborate on them Mar 08 03:36:32 i'm kinda wondering why erik meijer has been quiet on the Rx front for a while now ... last year he was always talking about it. Mar 08 03:36:57 once ben c left netflix / rxjava project everything wound down Mar 08 03:37:48 I don't even know what functional programming really means Mar 08 03:37:50 does anyone? Mar 08 03:37:51 what does netflix have to do with rx? Mar 08 03:38:06 wabz: it definitely seems a little gimmicky Mar 08 03:38:10 RustyShackleford ben started rxjava working at netflix Mar 08 03:38:16 I think it means passing around void * Mar 08 03:38:31 but i guess there were some guys there from MS that cross pollinated Mar 08 03:38:56 I don't believe how many languages it supports. What is it written in? C? Mar 08 03:39:14 what supports ? Mar 08 03:39:41 reactivex Mar 08 03:39:52 aren't they all the same project? Mar 08 03:39:54 each impl is standalone Mar 08 03:40:14 i'm suprised. I figured they had one impl and bindings Mar 08 03:40:41 for jvm yeah, but the JS is another one, cocoa another, c# another, etc Mar 08 03:42:03 One of the reasons it's hard to learn functional languages I think Mar 08 03:42:11 Is because it's non-Algol Mar 08 03:42:38 I'm used to moving from C to Java to C++ to Perl to Python to Javascript...but all of it is Algol-like....Scheme isn't Mar 08 03:45:07 the functional programming in scala book is really good, and doesn't require any scala knowledge, either Mar 08 03:45:18 but it's much more advanced than rx Mar 08 03:47:39 Ologn, eh, that's not really the reason Mar 08 03:47:49 functional programming is sorta hard to wrap your head arounde Mar 08 03:47:56 Ologn, functional programming concepts are very different from typical imperative programming Mar 08 03:48:11 but the idea of writing your functions to be stateless is great Mar 08 03:48:42 RustyShackleford, it's natural once you start doing it Mar 08 03:49:02 I messed around with Haskell for a few months. It was pretty cool definitely Mar 08 03:51:34 if you can grok haskell, rx should be trivial Mar 08 03:55:08 wabz, it means programming with functions, duh Mar 08 03:56:14 pfn: I did not really know haskell Mar 08 03:56:24 g00s: becasue scala is not scary ? Mar 08 03:56:33 I wrote it somehow by reading lots of docs. If I looked back at that code I would not understand it Mar 08 03:57:08 g00s: been walking on my foot finally. Crutches to take some of the weight. Its the oddest thing learning how to walk again Mar 08 03:59:34 actually rx might be easier if I brush up on the Haskell Mar 08 03:59:42 ha. such a nice annotation - @Size Mar 08 04:02:30 i was trying to get sign in using google to work and now the emulator has got stuck requiring the "google apps device policy" app... which constantly crashes Mar 08 04:02:50 anyone know how to fix this thing (google was unhelpful)? Mar 08 04:39:29 I want on Observable that makes network calls, writes to db, and then tells the subscriber when its done Mar 08 04:39:35 I don't want to return anything Mar 08 04:40:17 I'd just return the data ignore it Mar 08 04:40:34 or you could have an observable of ? Mar 08 04:43:41 RustyShackleford: so you want to have 2 subscribes Mar 08 04:45:02 can I do that? multiple subscribers? Mar 08 04:45:07 never ocurred to me Mar 08 04:45:27 my coworkers in India just wished me a happy Women's Day Mar 08 04:45:30 how nice Mar 08 04:48:08 ha Mar 08 04:48:22 international women's day is my birthday Mar 08 04:48:26 today! Mar 08 04:48:53 I always found it weird how IWD is such a big deal in some places, no one in england could tell you when it is Mar 08 04:49:06 it's a notional holiday in cambodia Mar 08 04:49:33 I never heard of it before Mar 08 04:49:59 I don't think its a thing in the US Mar 08 04:50:50 *national Mar 08 04:55:57 is there a decent way to check if the app is coming from background or not? Mar 08 04:56:14 a lot of answers I see are kind of self managing a counter variale or a boolean Mar 08 04:56:19 variable Mar 08 05:03:24 RustyShackleford: I never had problem with rxjava :P Mar 08 05:03:35 would say that more problem with dagger Mar 08 05:12:20 gordon_: I got it wired up Mar 08 05:12:43 dagger sorta makes sense, and makes no sense at all. same as rx honestly Mar 08 05:13:06 so wait, are marble diagrams supposed to make sense too? Mar 08 05:21:05 lol Mar 08 05:23:06 examples with lamdas are also really messing with my head. Is that supported on android yet? Mar 08 05:24:02 looks great for someone that really knows the framework Mar 08 05:27:01 RustyShackleford kinda with retrolambda - never used it Mar 08 05:30:24 if you're going to use rxjava you should definitely use retrolamdba and learn to use them Mar 08 05:30:25 Also IDEA (well AS) will fold your source code to look like lambdas Mar 08 05:33:51 "4chan Founder Chris Poole Will Try To Fix Social At Google" heh Mar 08 05:35:06 CedricBeust is it true that lambdas in kotlin are implemented better than java ? Mar 08 05:38:57 g00s: yes Mar 08 05:39:07 They have proper closures Mar 08 05:39:31 and when declared inline, they will won't even incus an object allocation overhead Mar 08 05:39:33 "Unlike Java, the variables captured in the closure can be modified:" well thats nice Mar 08 05:39:49 RustyShackleford: lambdas are great Mar 08 05:39:51 Bytecode wise, both languages are about on par Mar 08 05:39:53 thanks loke Mar 08 05:40:54 I find it incredible that Java 8 didn't bother to implement closures. There is no reasonable explanation other than sheer stupidity. Mar 08 05:41:20 loke: What do you mean? Mar 08 05:41:24 There are plenty of things to be annoyed at with Kotlin, but they sure fixed a lot of Java crazyness. Mar 08 05:41:37 CedricBeust: Mean by what? Mar 08 05:41:48 That Java 8 doesn't implement closures Mar 08 05:41:57 CedricBeust: I mean exactly that. Mar 08 05:42:17 Java 8 has both syntactic and bytecode support for closures, I don't understand what you mean Mar 08 05:43:03 CedricBeust: You must be using an incredibly strained definition of the word "closure". Mar 08 05:43:14 I'm curious about your definition Mar 08 05:43:59 The ability to close over free variables from outer scope. (the Java 8 model is no more than a shorthand for passing arguments to the inner scope) Mar 08 05:44:21 Right. Java has supported its current style of closures for almost 20 years, not sure what's so surprising. Mar 08 05:44:50 CedricBeust: Calling that a closure is the problem. Mar 08 05:45:28 I see being able to modify over closed variables as dangerous (as is mutability overall). I like the approach of disallowin git. Mar 08 05:47:30 CedricBeust: I could see that argument as having some validity if Java was otherwise a language which promoted immutability. But when the damn thing doesn't even support try/catch forms returning values, forcing immutability of variables in this one case only serves absolutely no point. Mar 08 05:48:09 The more immutability, the better. Just because Java doesn't enforce it in other areas doesn't mean it's useless to enforce it in others. Mar 08 05:48:19 CedricBeust: And I believe that we have discussed the virtues of static typing in the past :-) Mar 08 05:48:34 This current discussion is completely unrelated to static typing. Mar 08 05:49:22 What defines a true closure is completely uninteresting to me, I care more about the practical implications of adopting certain semantics. Mar 08 05:49:23 CedricBeust: We both know that the reason for Java 8's forced final have nothing to do with the higher ideal of promoting immutability. Mar 08 05:50:12 (an ideal I don't disagree with, mind you) Mar 08 05:50:51 also, I sloppily used the expression "static typing" when I was actually referring the ideals of Haskell (which includes both static typing as well as immutability) Mar 08 06:07:19 is it ever possible for Fragment#getTarget() to return null? (if target has been set, even through screen rotations, etc) Mar 08 06:11:58 meh, closing over free variables for the lose Mar 08 06:11:59 :P Mar 08 06:19:49 But it's a more proper definition! Mar 08 06:24:34 " Prior to JELLY_BEAN you must not modify the insets or else you and Android will be unhappy." Mar 08 06:26:06 is there anything on d.android.com that just talks about insets? they are mentioned everywhere but i can't find any place thet describes wtf they are Mar 08 06:28:52 i need pictures damn it :) Mar 08 06:29:04 why do the android doc people hate diagrams so much Mar 08 06:35:26 out of curiosity what's the difference between onStart() and onResume()? I use onResume() a lot but almost never touch onStart Mar 08 06:35:38 insets are like padding Mar 08 06:35:39 that is all Mar 08 06:39:49 g00s: SOA people like diagrams, you should try ;) Mar 08 06:40:08 maybe you will also get into some meeting with no sense Mar 08 06:41:46 gordon_ uh what ? Mar 08 06:42:05 you are not making sense :) Mar 08 06:42:07 see you havent been in big corporation :D Mar 08 06:42:29 irrelevant Mar 08 06:42:39 it is Mar 08 06:42:44 if you associated diagram with boring meetings in big corpo, you have serious issue Mar 08 06:42:54 or I'm just joking Mar 08 06:42:55 bigger than Android Studio! Mar 08 06:43:06 guess which one was that ? Mar 08 06:44:13 AS was partially frozen this morning, so I decided to "invalidate cache & restart"... It even fails at "invalidate cache & restart" Mar 08 06:44:45 did keyboard stopped working for you ? Mar 08 06:45:04 my keyboard has no issue Mar 08 06:45:16 so only I have this bug.. Mar 08 06:55:24 Is there a goto Parcelable annotation library? Mar 08 06:56:01 I've always made my objects parcelable manually and it's an annoying amount of overhead Mar 08 06:56:46 konk3r yeah there are some libs, but your google is as good as mine Mar 08 06:57:31 g00s: Yeah, I've seen libraries for it so I'm going to check them out, thought I'd see if there was a consensus on which one to use Mar 08 07:16:25 damn, when'd gordon_ get so good at trolling them fools Mar 08 07:19:30 i guess he can learn about trolling whenever scala comes up Mar 08 07:19:48 lots of opportunity there Mar 08 07:22:48 konk3r: google through github, there are one or two Mar 08 07:23:09 I'm checking out https://github.com/johncarl81/parceler right now Mar 08 07:23:11 looks promising Mar 08 07:23:59 yeah, I was thinking about that one. but it works like wrapper. meh.. imo Mar 08 07:24:16 Hello.. I just started to use Android SDK. Rendering problems were relentless, but somehow i got them through by tweakind sdk version. But now problem is that layout manager or whatever it is called is gray and I can't add any components there.. Mar 08 07:24:29 Any advice?? screen cap http://snag.gy/DyvC5.jpg Mar 08 07:25:49 Luihu: screens are mostly useless. use pastebin to illustrate questions Mar 08 07:27:12 Is there a simple way to build a list of items that scroll item by item? For example, showing three items at once, then scrolling one by one, always showing only three of N items. Mar 08 07:28:11 I am currently using HorizontalScrollView > LinearLayout, but the scroll is "continuous", not "discrete" Mar 08 07:28:31 vigilancer I am very new to this, so can you tell me how to illustrate the problem in pastebin? I haven't added any code, I am following a tutorial that uses a scaffold and it begins by adding GUI objects but my layout manager seems totally different than the videos.. Mar 08 07:29:45 xrash, viewpager Mar 08 07:31:43 I think this is how the layout manager should look like.. http://snag.gy/nrjHN.jpg Mar 08 07:32:09 https://github.com/Taig/Soap Mar 08 07:32:20 that is such an awesome parcelable library Mar 08 07:32:38 Luihu: open pastebin site, copypaste code that you have problem with, publish it, paste link to code with question. If you feeling lucky somebody will pick it up Mar 08 07:34:42 everithing better in scala ;P Mar 08 07:36:03 Luihu: it this case code = content of xml file, describing your view Mar 08 07:37:13 vigilancer: I'll do it, will take a minute though Mar 08 07:37:40 vigilancer, everything is Mar 08 07:38:29 literary, can't argue :) Mar 08 07:56:51 http://pastebin.com/FW69UCD2 Mar 08 07:57:10 maybe i should try reinstalling the sdk? Mar 08 07:57:57 it just crashed (again) Mar 08 07:58:19 Luihu: pastebin stacktrace Mar 08 07:59:09 vigilancer: sorry? I don't understand.. Mar 08 08:00:11 Luihu: google stacktrace than :) Mar 08 08:00:44 vigilancer: I will do it, sorry i am very new to this.. Mar 08 08:01:43 nothing to be sorry about, it's learning process Mar 08 08:12:58 How to make dynamic graphs like http://javadocmd.com/blog/content/images/2014/Sep/interstellar_inc.png with clickable nodes Mar 08 08:22:10 Good morning dear developers! Let's rock 'n roll :P Mar 08 08:25:35 Lately I use Fragments a lot instead of Activities. I just have one Activity and there I host all Fragments I want. But now I wonder when to create another Activity instead of a Fragment? What do you think? Mar 08 08:27:30 Depends on the application flow Mar 08 09:04:09 In the SDK manager I have 'Android Support Library' version 23.2 installed. But when I compile, it looks for ../android/support/support-v4/23.0.0/support-v4-23.0.0.pom Mar 08 09:04:43 is there a way to install version 23.0.0 of the android support library, or else tell gradle to use version 23.2 instead or something? Mar 08 09:07:55 johnflux, are you in Android Studio? Mar 08 09:08:26 ktwo: no, but I have that installed and run that just to run the sdk manager Mar 08 09:08:54 i usually just update the build.gradle file to use the latest version in AS Mar 08 09:08:58 "compile 'com.android.support:appcompat-v7:23.2.0'" Mar 08 09:09:14 ktwo: thanks Mar 08 09:11:49 I have an activity with only Fragments and all of them only in portrait mode, but for one Fragment, I want to replace it with an Activity. The reason for that is, in the Activity I want to show video streaming in portrait mode as well as landscape mode, hence an Activity instead of Fragment. What do you think about this solution? Mar 08 09:13:52 I was checking how to enable landscape mode in a fragment and found the solution by overriding setUserVisibleHint(). But I don't like it so much, because going back to previous fragment I have to override the same method again to lock it back to portrait. Mar 08 10:00:49 hey all Mar 08 10:01:00 im researching the OTG capability of android devices Mar 08 10:01:25 i need to know if a cable exists which would allow for the android device to charge as well as be a host to a usb flash drive Mar 08 10:12:43 I'm fairly sure that's impossible with a regular cable Mar 08 10:46:59 Afternoon all. Mar 08 11:30:42 hi does list entries have onclick listener Mar 08 11:32:25 Hi all, is it practice to cast an Activity to getActivity to change a primitive (in this case a boolean)? i.e. ((MyActivity)getActivity).setExampleBoolean(true); Mar 08 11:32:41 would it be better to use an interface in this case? Mar 08 11:51:56 Hey all, im working on a udacity course and im getting an error from android studio for this snippet of code: line 83 https://bpaste.net/show/2e1421dd781d Mar 08 11:55:01 That seems fair, given that there's no declaration for "mForecastAdapter" anywhere. Mar 08 11:55:20 Hey yall ... Mar 08 11:57:35 could someone tell why i am not able to create a new user on firebase with this code : Mar 08 11:57:50 http://pastie.org/10751996 Mar 08 11:58:32 http://postimg.org/image/dno8neml3/ Mar 08 11:58:33 fizzie, ty! Mar 08 12:45:56 Hi all! I am looking for the command line documentation of the new emulator - unfortunately, `emulator —help` no longer works („PANIC: HOME is defined but could not find (null).ini file“) Mar 08 12:45:59 Any hints? Mar 08 12:53:39 Hi all, does anyone know if it's possible to change the size of my toolbar navigation icon? I'm currently using toolbar.setNavigationIcon(R.drawable.menu_icon); which works well, but the image is much larger than i'd like. Mar 08 12:53:59 I'd like to avoid resizing the image itself if i can Mar 08 12:56:47 rmrrn, already thoughout about using a vector ? Then resizing is easier Mar 08 12:59:06 ktwo: I haven't no but will consider. I can't actually see anyway to specify the size here though! Mar 08 13:00:01 height/width inside ktwo: ahh I see. if i'm unable to use a vector, is there anyway to do this? I tried defining another drawable with an imageview which didnt work unfortuantely Mar 08 13:12:16 for this: https://github.com/udacity/Sunshine-Version-2/blob/2.01_add_network_code/app/src/main/java/com/example/android/sunshine/app/MainActivity.java#L130 I get an error: "CANNOT RESOLVE SYMBOL" Mar 08 13:27:29 rmrrn, just resize the image (imho). Why can't you use vector? Image too complex? Mar 08 13:46:44 Is it possible to use the design support library (i.e Snackbar) in android TV (Leaseback Theme). I get an error about "You need to use a Theme.AppCompat theme (or descendant) with the design library." Mar 08 13:47:07 Leanback* Mar 08 13:53:14 hey could someone tell me the proper syntax for creating new user on firebase through android studio Mar 08 13:53:46 mFirebaseRef.createUser() Mar 08 13:54:03 i cant get the code that goes between () right ? Mar 08 13:54:07 no documentation for iit? Mar 08 13:54:32 there is i've been reading and searching online for it but i cant fix my code ? Mar 08 13:54:52 http://postimg.org/image/dno8neml3/ Mar 08 13:55:13 what are you overriding Mar 08 13:55:18 http://pastie.org/10751996 Mar 08 13:55:19 are you sure that method needs overiding? Mar 08 13:55:43 elyess, use an appcompat theme :) Mar 08 13:56:45 am not sure, am just trying to learn how it works, thus i pasted this code shown in the pic but it is not working Mar 08 13:57:37 remove the @override above onclckingbutton Mar 08 13:58:10 you mean : @Override public void onSuccess Mar 08 13:58:22 Hi.. How can I send array bytes with httpUrlConnection? Mar 08 13:58:22 nope Mar 08 13:58:26 onClickingButton Mar 08 13:59:02 no @Override above that other than the @Override above @Override protected void onCreate Mar 08 13:59:30 oh that one is removed already Mar 08 13:59:37 still the same error Mar 08 13:59:54 I can see it in the screenshot Mar 08 13:59:59 it's there mate. Mar 08 14:00:47 http://postimg.org/image/4n6ovymq1/ Mar 08 14:01:34 you need to close createUser Mar 08 14:01:48 missing ) at the end of the anonymous callback metho Mar 08 14:02:26 hmmm ... let me see ... just a sec Mar 08 14:05:34 great, but now there is problem :http://postimg.org/image/o84bs1btp/ Mar 08 14:06:07 which i never got before, can not be instantiated ? Mar 08 14:19:53 I'm looking for a way to get *a* view within an activity. it doesn't matter which view, i just need one. (for snackbar) Mar 08 14:20:44 I tried to do it with activity.getCurrentFocus(), but it seems like there's a chance that nothing is focused. Mar 08 14:30:23 okay Mar 08 14:30:30 back to seeing how to do MTP/PTP over OTG Mar 08 14:30:44 Hello guys, what's the best method to have a continuous video streaming on orientation change? At the moment I use a VideoView object and use that to stream in portrait mode, which works well. I was thinking of saving the stream url and progress position and than after activity is recreated, I than restart the streaming setting the last progress position. What do you think? Mar 08 14:31:35 Number5: does youtube pause when you rotate? Mar 08 14:31:56 I am pretty sure they buffer the video somewhere else and just cut the showing of said buffer to the screen Mar 08 14:32:11 then resume once it's rotated Mar 08 14:32:21 tx, well, I don't have the feeling it pauses, but it could pause for a very short time, not noticeable by me. Mar 08 14:33:15 tx, ok, but now I use a VideoView object doing the streaming, I don't know what technique is used by Youtube. Mar 08 14:33:23 imho, just save the state of the video Mar 08 14:33:27 position, quality etc Mar 08 14:33:37 reload on rotate Mar 08 14:34:30 To my surprise I could also play video from a MediaPlayer, which is more like a player without a video. Mar 08 14:35:08 dayum Mar 08 14:35:15 these MTP tutorials are so old! (honeycomb) Mar 08 14:35:19 nothing for newer APIs Mar 08 14:35:55 So I was thinking to save the mediaplayer in a singleton and reattach the view after orientation change, but that takes me longer to code and I have to think of a good pattern. Mar 08 14:36:04 tx, there are MTP tutorials? :) Mar 08 14:37:07 Mavrik: well, code samples ;) Mar 08 14:37:39 Huh, didn't know that support existed :P Mar 08 14:40:11 Mavrik: how do you think gallery apps open up when you plug a camera in via otg Mar 08 14:41:04 ktwo, i am already using the Leaseback theme for TV, hoe to use AppCompat with it? Mar 08 14:42:33 I'm adding radio buttons dynamically to a radiogroup. how do I make the radio button labels fill the width? Mar 08 14:42:51 tx, never did that :P Mar 08 14:44:00 Number5, you'll likely leak the activity Mar 08 14:44:40 hot Mar 08 14:44:41 Zharf, because I have to pass a context? Mar 08 14:47:50 If I make an AsyncTask static, how can I update the UI based on the result of the AsyncTask if I cannot reference the UI from onPostExecute? Mar 08 14:48:48 you need a reference to the ui, or use something like eventbus to tell the activity/whatever to update Mar 08 14:49:22 Khaytsus: none Mar 08 14:49:32 whoops, wrong #android channel ;) Mar 08 14:50:28 And what if I want to use the same method from within the Task as well as outside the Task? Mar 08 14:54:03 hmm Mar 08 14:54:12 trying to get the class of a usb device attached Mar 08 14:54:18 get 0 back, so no class? Mar 08 14:55:17 is this a good book if i want examples on how to create an app for my site? Mar 08 14:55:19 http://shop.oreilly.com/product/9781785883262.do Mar 08 14:55:45 my site uses mysql db but the book has examples for sq lite Mar 08 14:55:46 is it ok? Mar 08 14:55:52 sql slite Mar 08 14:56:58 Number5, yes, you can use application context probably, but it's still a bit dodgy... can you retain a fragment? Mar 08 14:59:29 The problem will be attaching the player to the new surface :) Mar 08 14:59:30 does sql lite interface the same way as mysql from my app in android-studio ? Mar 08 15:00:05 Zharf, I can, but I want to try first by setting the progress position after recreating Activity and see what the result looks like. I secretly fingercross that VideoView caches the buffered data so the the whole process goes much smoother. Mar 08 15:00:12 why XML instead of HTML :/ Mar 08 15:00:20 Mavrik, I'm now using straight forward VideoView. Mar 08 15:02:02 Is it possible to do chrome webview debugging from inside the emulator? Is there a place I can read how to get USB debugging working through the emulator? Mar 08 15:02:09 Mavrik, is it a problem? I haven't used MediaPlayer in years :p Mar 08 15:02:49 Zharf, yep, accelerated surface tends to be destroyed Mar 08 15:02:52 we have a custom video player in our current project and in our previous project I wrote my own player using MediaCodec Mar 08 15:02:55 and that annoys MediaPlayer Mar 08 15:03:05 Since you can't reattach on some devices. Mar 08 15:03:21 Which means you need to recreate / reload video which makes a noticable flicker + delay. Mar 08 15:04:01 Mavrik, ok, so any other options isn't available with standard Android components? Mar 08 15:04:05 im getting "cannot resolve symbol R" Mar 08 15:04:26 django_, rebuild project? Mar 08 15:04:35 Number5, how? Mar 08 15:04:43 'Rebuild' Mar 08 15:04:51 Zharf, hence MediaCodec is usually a better idea when it works Mar 08 15:04:54 Number5, still Mar 08 15:05:00 YouTube uses ExoPlayer which renderes via MediaCodec Mar 08 15:05:05 In 'Build' menu Mar 08 15:05:08 also restarted android studio Mar 08 15:05:15 Number5, yeah i found it, didnt work Mar 08 15:05:49 django_, 'File' -> 'Invalidate cache, restart' Mar 08 15:06:57 Number5, didnt work :/ Mar 08 15:07:02 Mavrik, MediaCodec is terrible before api 18 or 19 though Mar 08 15:07:06 If that doen't work, check whether a library is added correctly or something like that. My experience is AS gives weird error that makes you search in the wrong place. Mar 08 15:07:06 wait Mar 08 15:07:10 i think it worked on one file Mar 08 15:07:11 Zharf, yeah, they do fallback :) Mar 08 15:07:13 it's sad how bad android media apis are Mar 08 15:07:21 Hence the reason I'd use ExoPlayer over anything manual :P Mar 08 15:07:33 Zharf, on API 23 we got the API to tell us how many HW decoders there are \o/ :P Mar 08 15:07:55 we have a proprietary player in the app I'm currently working on Mar 08 15:08:34 Does anyone here knows if it's possible to get an Android emulator connect to Chrome debugging environment? Mar 08 15:09:13 Mavrik, maybe we can use google provided media apis in the next 20 years then Mar 08 15:09:24 minSdk 23. Mar 08 15:11:25 last year i bought a book called learning php,mysql & javascript and built a website around it, now im looking to build an app based on my website (my website accesses a mysql database), which book from o'reilly do you guys recommend for this? they have like 4 pages of books listed for android developement Mar 08 15:12:20 I recommend the texts of the bible known as Mar 08 15:12:25 "StackOverflow" Mar 08 15:15:23 Can anyone explain why when you start a new activity the transition from the old to the new seems jerky? Mar 08 15:18:06 it doesn't Mar 08 15:18:14 stop hogging the main thread Mar 08 15:19:27 "sb_device_claim_interface failed" Mar 08 15:19:37 great, looks like the internal USB library doesn't want to play nice Mar 08 15:22:35 pfn: The application may be doing too much work on its main thread. Mar 08 15:22:42 How can I avoid this? Mar 08 15:24:10 Offloading heavy tasks to a background thread Mar 08 15:24:59 use a service! Mar 08 15:25:20 (or an asynctask) Mar 08 15:25:28 depends on what you want to do really Mar 08 15:26:01 I guess this is partly due the me not using Fragments / Views and having everything within the activity class? Mar 08 15:26:11 not really Mar 08 15:26:16 that all runs in the UI thread Mar 08 15:26:23 you're just doing a lot of other non UI things Mar 08 15:26:29 fetching data? processing data? Mar 08 15:26:35 doing lots of calculations? Mar 08 15:26:36 Fetching data from Firebase Mar 08 15:26:42 bingo Mar 08 15:26:42 That will be it. Mar 08 15:27:00 throw that in an asynctask Mar 08 15:27:01 but I have a lot of logic before I fetch the data, would that cause it to be even worse? Mar 08 15:27:10 like what? Mar 08 15:27:56 For example, I've got logic to ensure that the user is authenticated, logic to check what role the user has and the depending on the results different items are added to the navigation drawer Mar 08 15:28:38 I got MTP working! Mar 08 15:28:44 It's just really slow Mar 08 15:28:48 but that's because MTP is slow. Mar 08 15:30:19 tx pduin what you reckon? Mar 08 15:30:59 how do you know a user is authenticated Mar 08 15:31:22 Sounds like all of those things except for the nav drawer could be handled in the background Mar 08 15:31:38 any idea how to get a global snackbar? I have the issue that I can not consistently get a view out of my activity without changing every single activity. Mar 08 15:31:38 ^^should* Mar 08 15:31:59 iirc doesn't android throw an exception if you attempt to use a data connection on the UI thread these days Mar 08 15:32:03 because it's silly :) Mar 08 15:32:08 (doing it) Mar 08 15:32:09 .getCurrentFocus() sometimes returns null, so it won't work. Mar 08 15:32:43 Syzygy: You need to bind the snackbar to something though Mar 08 15:32:53 and there's no view id that is common to all activities so that i could do findViewById(R.id.rootView). Mar 08 15:33:22 tx: I'm binding it to the current activity Mar 08 15:33:31 Syzygy: http://stackoverflow.com/questions/15995297/how-is-facebook-chat-heads-implemented Mar 08 15:33:38 you could do something like what FB does with chat heads? Mar 08 15:35:53 I've done that before (not with snackbars) but I feat that it might lead to issues. Mar 08 15:35:56 I can try though Mar 08 15:36:30 tx checking if getAuth() returns null from Firebase Mar 08 15:38:32 pduin would you have all those tasks in an AsyncTask or would you have multiple AysncTasks? I don't understand why having AsyncTasks is better, Android runs the application on a single thread, if I add AsyncTask would it not have the exact same load because I carry out everything within onCreate()? Mar 08 15:38:52 Syzygy: All activities have android.R.id.content Mar 08 15:39:13 markyosullivan: nawh Mar 08 15:39:19 asynctask makes a new thread in the background Mar 08 15:39:24 hey all Mar 08 15:39:37 there are callbacks that you can hook in to before the task runs Mar 08 15:39:44 on "progress" (defined by you) Mar 08 15:39:46 for this: https://bpaste.net/show/5177ad32d128 and another XML im getting: cannot resolve symbol @string/action_refresh Mar 08 15:39:46 and when it's done Mar 08 15:40:19 django_: the string doesn't exist Mar 08 15:40:25 :\ Mar 08 15:40:32 tx, what? Mar 08 15:40:41 SimonVT: i'll try that, thanks. tx: the windowmanager also does not provide me with a view, just something to attach a view to, but still thanks Mar 08 15:41:22 that seems to work, thanks SimonVT Mar 08 15:41:31 Syzygy: isn't that good enough? Mar 08 15:41:37 attach the snackbar to the window manager Mar 08 15:41:50 tx I take it something like AsyncTasks would be used for displaying a loading animation to indicate to the user that the app is retrieving data? Mar 08 15:41:53 snackbar is similar to a toast, it's not a view Mar 08 15:42:08 (at least not exposed as a view) Mar 08 15:42:08 markyosullivan: you could certainly use it to do that Mar 08 15:42:14 ah okay Mar 08 15:42:30 I quickly searched on GitHub and found NanoTasks which are more lightweight apparently: https://github.com/fabiendevos/nanotasks Mar 08 15:42:32 Syzygy: do if you displayed a snackbar and finished the activity Mar 08 15:42:38 would it stay there? Mar 08 15:42:38 tx ever had any experience with it? Mar 08 15:42:40 (for a moment) Mar 08 15:42:44 so** Mar 08 15:42:47
