**** BEGIN LOGGING AT Mon Sep 26 02:59:58 2016 Sep 26 03:00:12 shmooz: You definitely should learn a revision-control system, though. Sep 26 03:00:46 They make software development a thousand times easier (and funner). Sep 26 03:01:49 TacticalJoke: Pretty sure there was a movie recently released where the premise is a dare app Sep 26 03:02:02 orbyt_: Neat. Sep 26 03:02:25 http://www.imdb.com/title/tt3531824/ Sep 26 03:08:45 lol who doesn't use version control these days Sep 26 03:09:04 version shmersion Sep 26 03:09:47 I don't need no stinkin version control Sep 26 03:09:54 You do, shmooz. :E Sep 26 03:10:12 I'm gonna nag you about this until the day I die. Sep 26 03:12:20 Maybe in the future there'll be automatic version control that reads our minds to delineate versions. Sep 26 03:19:02 Maybe we should create an #android-dev bot. One of its functions could be to annoy shmooz about not using version control. Sep 26 03:19:46 It could also be used to insult people, like in ##java. Sep 26 03:20:08 shmooz yeah pick up git or hg, if you're interviewing, ank they find out you don't use VC - imho that automatic grounds for "well get back to you" :D Sep 26 03:23:18 alias git='cp -rv . `date +%Y%m%d`' Sep 26 03:24:34 i think its rm -r not cp -r :D Sep 26 03:59:43 form validation is the most tedious thing Sep 26 04:21:41 bankai_ https://www.thedodo.com/man-builds-special-kayak-for-his-dogs-1435475908.html Sep 26 04:21:52 borrow the plans for your labs :) Sep 26 04:23:09 alex_PP yeah :( Sep 26 04:23:36 i couldn't think of anything worse! Sep 26 04:25:52 When you accidentally close Android Studio... Sep 26 04:27:49 bankai_ why, not trustworthy? :P Sep 26 04:28:16 I have rather desperate hopes they'll fix the new misbegotten layout editor Sep 26 04:28:20 of course not trustworthy, they'd last maybe four seconds Sep 26 04:28:33 Like, who thought it was a good idea to remove the ability to copy+paste in tehre Sep 26 04:28:56 i still haven't tried it Sep 26 04:28:59 * g00s lazy Sep 26 04:29:44 Well, they made the renderer more accurate... but a whole host of functionality fell off in the process, and it does this weird freezing thing when you try to change some of hte properties Sep 26 04:29:57 Dagmar: Are you using ConstraintLayout? Sep 26 04:30:03 I go change the XML directly a hell of a lot more often Sep 26 04:30:20 TacticalJoke: That's an N thing, right? Sep 26 04:31:11 ...or is that the project name for what slipped into 2.2 probably a bit before it's time Sep 26 04:31:16 It's in `com.android.support.constraint:constraint-layout:1.0.0-alpha8`. Sep 26 04:31:40 sounds like it has a ways to go Sep 26 04:32:02 Nah, I don't use those views yet Sep 26 04:32:21 At the moment I've got a screen so packed full of buttons i'm having to specify most of it by dip Sep 26 04:33:15 i have my trackpad sensitivity at 10. now what Sep 26 04:33:20 need 11 ! Sep 26 04:33:53 i used GridLayout for buttons & forms Sep 26 04:34:45 Yeah, both having tons of individual buttons and using the Design view for something other than ConstraintLayout are red flags for me. Sep 26 04:35:06 WEll, I've got a box with 18 buttons on the left and another on the right, and considering that ConstraintLayout didn't exist when I started on this, I don't much care Sep 26 04:35:26 THe buttons also double as indicators, by design. Sep 26 04:36:54 Doesn't really change the fact that the layout editor lost a lot of functionality from 2.1->2.2 Sep 26 04:37:53 Sure the blueprint view is cute, but the number of times I've had it refuse to put focus on a value when I hit DEL and *poof* there goes the view widget... SMH Sep 26 04:38:25 I'm not refactoring the UI to use ConstraintLayout while the editor still actively pisses me off Sep 26 04:39:49 Dagmar: I didn't mean to suggest using ConstraintLayout. I've never even used it. Sep 26 04:42:42 Dagmar: What I mean is that, AFAIK, top Android devs don't use the Design view (this might change when ConstraintLayout is fully released). Sep 26 04:43:02 I think top Android devs probably rarely (or never) add 18+ buttons to a layout. Sep 26 04:43:19 My conclusion is "There might be a better solution". Sep 26 04:44:02 I don't mean it like "You mustn't be a top Android dev". I mean it in a "What would Jesus do" kinda way. Sep 26 04:56:24 how to run thread in a onitemclickListener Sep 26 05:02:33 iron_host, what're you trying to do? Sep 26 05:02:52 if you really want a new thread (you don't) just call new Thread() Sep 26 05:23:38 how can i place live log view in android application Sep 26 05:24:44 Is it possible to have a persistent soft keyboard in a view displayed always ? Sep 26 05:41:12 Anyone using ConstraintLayout in production app yet? I've been testing it out again recently and it seems pretty stable. I have a new project coming up soon and was thinking of using it as the "default" ViewGroup for the app Sep 26 05:41:50 Are there any remaining big performance problems ? I haven't seen much about it online Sep 26 05:44:39 liuwenhao, I'd be interested in hearing how you get along with it if no one else any any opinions Sep 26 05:47:25 I have been playing with it in a side project app, none of my layouts are very complex (although I hear ConstraintLayout is great when you want to get rid of very complex nested layouts). Last time I used it was alpha1 and it was completely broken, alpha8 is actually kind of nice to work with Sep 26 05:48:31 Biggest problem I have is that you are basically forced to use Android Studio's design mode since it generates a huge amount of XML which is pretty annoying Sep 26 05:50:22 I can see it saving a lot of time if I had to do a very complex layout from scratch vs. using a RelativeLayout Sep 26 05:52:18 I usually write a layout for complex stuff Sep 26 05:52:22 easier than that? Sep 26 05:52:23 I hope it ends up good. In the meantime, I'll stick with basic FrameLayouts/LinearLayouts and custom ViewGroups. Sep 26 05:52:38 suppose that depends on the exact layout you're working on Sep 26 05:59:52 Good morning, guys! Sep 26 06:13:29 hey guys, any idea why my toolbar is covering over a portion of my recyclerview? https://gist.github.com/JelloRanger/c09aa97c685e3ad7b750a2fdd25648cd Sep 26 06:26:10 I enabled jack in my module and used JavaVersion.VERSION_1_8 as sourceCompatibility and targetCompatibility but Android Studio still can't compile a lamba. What am I doing wrong? Sep 26 06:26:38 What Android version are you targetting? Sep 26 06:26:47 @Arancio Sep 26 06:27:54 liuwenhao: minSdkVersion 16 targetSdkVersion 24 Sep 26 06:29:02 Do you have compileSdkVersion set? (I don't know if that would make a difference) Sep 26 06:29:24 what's the error, Arancio? Sep 26 06:31:53 alex_PP: for one, Android Studio is not able to find MathOperation anywhere Sep 26 06:32:23 Arancio: Don't know what you're doing "incorrectly" but I set my build.gradle on a fresh project up to look like this: http://pastebin.com/9UAZKngS Sep 26 06:32:51 Sorry, Guys. I'm an idiot Sep 26 06:32:55 Where do you see that error? If it is an IDE bug, I'd just restart AS. If gradle is the thing throwing a fit, something else is wrong Sep 26 06:33:02 Oh neat. What went wrong? Sep 26 06:33:28 I expected MathOperation to be a standard Java class/interface while it was just an interface from a tutorial I was trying to follow Sep 26 06:33:43 You guys can call me moron from now on. Sep 26 06:33:58 Thanks for your attention Sep 26 06:35:13 These guys are rewriting a Reddit bot in JavaScript. It used to be in Python. https://redd.it/53wq5c Sep 26 06:36:03 Node.js, ew Sep 26 06:36:24 they'll be rewriting it in Go soon Sep 26 06:36:38 Just keep it in Python, python is perfect for bots Sep 26 06:37:00 but GO is hip Sep 26 06:44:23 hello , so i made a program to get a certain number of prime numbers( first 100, or first 1000, etc.) . but as the numbers approach 10000 or 25000 , the program takes upto 1 minute for 10,000 . and around 3-4 minutes for 25,000. this is not good. how can i optimise my code further ? code-->https://gist.github.com/codeboy101/a1e334774fd226d36c6ac7d68db33b7f Sep 26 06:45:08 superKiller: you made me smile. Thanks! Sep 26 06:45:44 superKiller: Just for info, is this a JVM question or an Android question? Sep 26 06:46:36 http://introcs.cs.princeton.edu/java/14array/PrimeSieve.java.html Sep 26 06:46:58 superKiller: http://stackoverflow.com/questions/453793/which-is-the-fastest-algorithm-to-find-prime-numbers Sep 26 06:47:36 superKiller: and that's not an Android question. But if you have other jokes like that please post them in this channel for a laugh Sep 26 06:49:46 anyone using admob mediation? do you need to setup a loadAd method for each network you're working with or admob does all that load&serve magic for you? Sep 26 06:50:21 Reminder that your current company will outsource your job to this guy in the next 5 years http://i.imgur.com/XaFeRai.png Sep 26 06:52:01 sorry got disconnected Sep 26 06:52:22 superKiller: we answered to your question while you were disconnected Sep 26 06:52:46 oh im sorry can you paste that answer again please ? Sep 26 06:53:05 superKiller: Why are you building a list? That's gonna be massively slow. Sep 26 06:53:07 use a sieve Sep 26 06:53:52 superKiller: you made me smile. Thanks! Sep 26 06:53:56 superKiller: http://stackoverflow.com/questions/453793/which-is-the-fastest-algorithm-to-find-prime-numbers Sep 26 06:54:01 superKiller: and that's not an Android question. But if you have other jokes like that please post them in this channel for a laugh Sep 26 06:54:12 liuwenhao: FWIW, I was able to find him just by googling "buddies who jus". :D Sep 26 06:54:38 Arancio: joke ? Sep 26 06:54:52 TacticalJoke: what do you suggest doing then ? Sep 26 06:55:48 have your app email you when someone requests a list of prime numbers, then hand calculate how many they need and email it back to them Sep 26 06:56:10 superKiller: In that code, you could print to `stdout` without creating a list. Sep 26 07:01:33 Ultimately, though, I would google this, as suggested by the other two. Sep 26 07:01:44 superKiller: some googling got me this http://stackoverflow.com/questions/9625663/calculating-and-printing-the-nth-prime-number Sep 26 07:01:53 don't build your list before you display Sep 26 07:01:58 build your list as needed Sep 26 07:03:09 alex_PP: yeah im trying to implement this --> https://en.wikipedia.org/wiki/Sieve_of_Atkin Sep 26 07:05:34 ok Sep 26 07:06:04 but you can still do this asynchronously Sep 26 07:06:51 display list, start a thread to do the computation, on every new prime update the list Sep 26 07:08:27 Why create a list? Sep 26 07:09:43 isn't that how we're ouputting? Sep 26 07:09:55 He's just printing to `stdout`. Sep 26 07:10:12 oh yeah Sep 26 07:10:21 is this a euler puzzle? Sep 26 07:10:52 thought we were doing android Sep 26 07:10:53 silly me Sep 26 07:33:25 just print out the even prime numbers and youre half way done Sep 26 07:33:40 leave the odd ones to others Sep 26 07:51:52 using android studio, I'm changing the code in one of the classes, it builds and run on the phone, yet the don't seem to be being applied. Sep 26 07:54:06 turn off instant run or completely rerun your project Sep 26 07:55:04 yes after every run I close the app on my phone. Sep 26 07:57:09 nug700: That's not relevant here. He's talking about Instant Run. Sep 26 07:57:34 Instant Run seems buggy, and it causes the problem you're reporting. Sep 26 07:57:42 ah Sep 26 08:00:51 disabled it in setting, and restarted android studio. The change in that class is still not being applied, however. Sep 26 08:01:36 Build > Rebuild Project. Sep 26 08:03:58 what is the change Sep 26 08:04:53 a Log.i call Sep 26 08:05:16 right above one I added a while ago, that is being called. Sep 26 08:05:47 and no problems or filters in your logcat Sep 26 08:06:19 the rebuild didn't apply it. Sep 26 08:07:06 what is the log exactly. perhaps something silly Sep 26 08:07:53 well the exact call is "Log.i(LogTag, "LOADED: " + data.ToJsonStr());", but I'll replace it with something more simple just to be sure. Sep 26 08:08:22 and LogTag isnt empty? Sep 26 08:08:40 it's not empty. Sep 26 08:08:48 ok :v Sep 26 08:08:59 set to the package name. Sep 26 08:09:53 Try `throw new Error("It worked.");`. If that works, try `Log.i("Test", "Test");`. If that doesn't work, it's probably LogCat filters. Sep 26 08:11:50 the function in question: https://gist.github.com/nug700/fb014b8c515235f9f6f72949dd9bc7ac Sep 26 08:12:36 the very first Log.i shows, and data.Title one shows, but not TEST123 or LOADED Sep 26 08:13:04 the logtag is net.designjournals Sep 26 08:13:28 nug700: Try what I said above. Cuts straight to the chase. Sep 26 08:15:02 what's the function attribute that ignores the Sep 26 08:15:11 "unreachabe code" error Sep 26 08:15:23 unreachable* Sep 26 08:15:49 Easiest way is probably to comment out everything underneath. Sep 26 08:17:07 Ctrl + / does that, BTW. Sep 26 08:19:24 yea change isn't taking effect Sep 26 08:19:53 Is the app closing and restarting when you run from Android Studio? Sep 26 08:20:18 I close the app on my phone, then start the app. Sep 26 08:20:29 You don't have to close the app manually. Sep 26 08:20:42 Just hit Run in Android Studio. Sep 26 08:21:52 Who knows what's going on. Maybe you have the emulator running in the background, and it's deploying to the emulator rather than your phone. Sep 26 08:21:56 Could be a million things. Sep 26 08:22:23 well changes on other Activity classes are taking effect. Sep 26 08:22:40 just that specific file isn't updating. Sep 26 08:26:12 Is `SetItems` really being called? Perhaps you could keep throwing errors further up the call stack until you hit one. Also, make sure Instant Run really is disabled. Sep 26 08:26:54 Ctrl+Shift+A > "instant run" > Enter Sep 26 08:28:09 oh.... the first point. It isn't being called. I forgot I had another overload of SetItems Sep 26 08:28:55 Also note that you're using C#-style naming. Methods and fields should be in camelCase. Sep 26 08:29:08 Hi, Sep 26 08:29:23 TacticalJoke: says who? Sep 26 08:29:34 that's just *one* coding style Sep 26 08:29:40 doesn't mean everyone needs to follow it Sep 26 08:30:03 If you don't use camelCase for public methods, for example, then everyone who uses your code will dislike you. Sep 26 08:30:12 It's a well established Java convention. Sep 26 08:30:40 eeyup Sep 26 08:30:41 It's *the* Java coding style. There's no other. Sep 26 08:30:57 I can use whatever coding convention I want Sep 26 08:30:58 do jars in libs resolve in android manifest? Sep 26 08:30:58 well java language itself wont forbid it Sep 26 08:31:02 It's my project, not Oracles Sep 26 08:31:27 and i will use this instead of self in python because i like it Sep 26 08:31:54 I'm the only person on this project. 90% of the coding I do is in C#. trying to break my normal convention and use java convention would annoy me way to much. Sep 26 08:33:17 nug700: Android forces you to break the C# convention, like it or not. Sep 26 08:33:37 Well, not in your code. Sep 26 08:33:46 I mean when you're calling Android code. Sep 26 08:33:57 It's up to you though. Just being pedantic. Sep 26 08:36:47 yea.. just where I put the capatal is pratically a reflex. if I was on a project with more developers I would make the effort to follow the conventions. Sep 26 08:37:28 Before Android, I was mainly a C#/.NET developer. It did feel weird at first. Sep 26 08:37:36 Having to use String.equals was also weird. Sep 26 08:38:42 what got me was the diffence with the enums and not being able to use primitive types with List<> Sep 26 08:38:51 lol Sep 26 08:39:30 Enums are one place where Java is actually better than C#. Sep 26 08:39:38 Though C# wins practically everywhere. Sep 26 08:40:12 Kotlin is a Java replacement which is quite C#-like. Better than C# in a few ways (e.g., the handling of nullity). Sep 26 08:40:46 Kotlin runs on JVM? Sep 26 08:40:49 Yeah. Sep 26 08:40:54 It can be used for Android too. Sep 26 08:41:18 interesting, guessing setting it up with android studio is a bitch though. Sep 26 08:41:24 In Kotlin, the equality situation is nice: `==` is value equality and `===` is reference equality. Sep 26 08:41:51 Really easy, in fact. It's created by JetBrains, the creators of IntelliJ (which Android Studio more or less is). Sep 26 08:42:06 Though if you're new to Java and Android it might be easier to stick with Java; not sure. Sep 26 08:42:27 and I don't feel like redoing the whole thing, lol Sep 26 08:43:50 Java is the official language for Android dev, so it's always gonna be simplest to use. Sep 26 08:44:01 Kotlin is really interesting, though. I actually feel like it's a better C#. Sep 26 08:44:16 Not just a better Java. Kinda apples and oranges, but it definitely improves upon C#. Sep 26 08:44:54 yea, I did try the monodevelop android stuff. was a pain. Sep 26 08:45:16 as all the documentation is for java Sep 26 08:45:50 or have you tried xamarin Sep 26 08:45:52 Yeah, and the framework source is Java, too. Sep 26 08:46:02 Ashiren: yea, that's what I meant Sep 26 08:46:16 oh Sep 26 08:46:17 The upcoming compiler for Android (Jack) is both written in Java and a Java compiler. Sep 26 08:46:37 java compiler written in java? Sep 26 08:46:42 They're gonna ditch javac and roll their own, for faster builds and maybe other stuff. Sep 26 08:46:46 what was first compiler ever written in Sep 26 08:47:51 https://en.wikipedia.org/wiki/Bootstrapping_%28compilers%29 Sep 26 08:48:03 I think javac was first written in C, and then Java. Sep 26 08:48:12 Maybe that's why it's called javac. :D Sep 26 08:48:14 mhm Sep 26 08:58:51 There a way to get the opened activity? Sep 26 08:59:43 the one that's being viewed. Sep 26 09:09:03 Jack is upcoming? I'm using it now... Sep 26 09:12:14 javac = java compiler like cc = C compiler Sep 26 09:17:33 For some unknown reasons using Stream#map requires API 24 Sep 26 09:17:42 When running the SDK manager (aka android) to upgrade the package "Android SDK Tools", the SDK manager is emptying the folder android-sdk-linux/tools where itself is located. Have anyone else experienced this issue? Sep 26 09:18:04 Fuck Android Sep 26 09:19:36 well streams are from java 8, and java 8 starts within api24 Sep 26 09:32:03 Arancio: having a bad week, are we? Sep 26 09:32:32 Ashiren: I don't understand what the java language version and the java library version have anything to do with the Android API version. I'm not trying to pass a stream to an Android API method (the compiler would prevent me to do that anyway). Sep 26 09:36:04 Is there a method in RxJava to collect an Observable into a List. I'm not talking about toList() which does Observable -> Observable> Sep 26 09:36:23 That was a question? Sorry Sep 26 09:37:30 I'm looking for the inverse of Observable.from() Sep 26 09:42:28 Arancio: well if the Android version doesn't have Java 8 installed, then how could it use those methods? Sep 26 09:42:43 and classes, etc Sep 26 09:43:41 Java 8 could be installed as part of the process of installing your app as we do on desktop computers Sep 26 09:46:20 The answer is observable.toList().toBlocking().single(); Sep 26 09:46:52 the part I was missing is toBlocking() Sep 26 09:47:14 java is an essential part of the the Android firmware. on desktop computers it is an extension. so it makes sense they would update it with the rest of the firmware. Sep 26 09:49:47 nug700: I guess my problem is that with API 24 they mean "Runtime 24" (VM + class library, with its API), which is what you said. They should not misusing the word API. Sep 26 09:52:45 but thats what has been since the beginning ~ Sep 26 09:52:50 they probably do that because they all update together, with the most relevant (to the app developers) changes being to the actual API Sep 26 09:52:54 nug700: Android is a flavor of Linux + the vm + the libraries. There is no reason why a version of that flavor of Linux could not run multiple versions of the vm, running multiple versions of the libraries (with API xx, API yy, etc.). They just didn't do it Sep 26 09:53:35 Anyway thanks for clarifying this concept to me Sep 26 09:55:19 ey. Sep 26 09:55:22 night night o/ Sep 26 09:55:26 night Sep 26 10:03:11 Im getting a "no hit" on my analytics Sep 26 10:03:21 does anyone know how to track this down? Sep 26 10:18:53 Is there anything in particular I need to do to disable my app from Android TV or Wear? or is that done by default? Sep 26 10:19:32 you need to do if you want your app on tv or wear Sep 26 10:19:53 Ashiren: I don't want it on TV or wear, so I don't have to do anything to block those devices? Sep 26 10:20:31 eeyup Sep 26 10:20:40 cool :) Sep 26 10:20:42 for wear it would need something like uses-feature wear Sep 26 10:21:18 for tv dunno, but doubt app would work out of the box Sep 26 10:21:37 OK, that's good Sep 26 10:22:40 another thing - if I want to keep the screen on only for a certain action, I presume I can just call: getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); Sep 26 10:22:49 what would be the opposite of that - to allow the screen to turn off? Sep 26 10:23:41 oh, removeFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON) Sep 26 10:24:08 hmm, removeFlags isn't a method on getWindow() Sep 26 10:24:20 clearFlags Sep 26 10:24:27 aaah Sep 26 10:24:50 that's cool :) Sep 26 10:26:02 try wakelock if you can Sep 26 10:26:06 sdousley, https://developer.android.com/training/scheduling/wakelock.html#screen Sep 26 10:26:37 wakelock for screen is deprecated Sep 26 10:26:57 partial wakelocks are for cpu only Sep 26 10:27:19 oops indeed Sep 26 10:27:20 * adq runs Sep 26 10:28:14 adq: that's where I read about getWindow()... Sep 26 10:28:24 yeah, my bad, totally confused Sep 26 10:29:28 oh, did that page used to have info on how to do it with a WakeLock like the CPU then, rather than getWindow().addFlags() Sep 26 10:32:39 nope, this page on the contrary does, sdousley: https://developer.android.com/reference/android/os/PowerManager.html Sep 26 10:34:45 hello sirs. im doing an app with a company on the style of "DYI" (do it yourself) and to publish it on my name I have to give them 4 things: keystore file url, password, alias name and password. the alias name is the name of my app, but the other 3 fields I don't have a clue on how to get it. I've Android Studio but it's designed to create apps, not to get this things only. am I making Sep 26 10:34:45 sense? any help would be welcome. Sep 26 10:38:44 you need keystore Sep 26 10:39:22 Build -> Generate signed APK, there will be button for creating new keystore Sep 26 10:39:42 you're talking on the android studio, right? Sep 26 10:39:42 keystore requires password, then it can contain several aliases, each protected by its own password Sep 26 10:40:11 each alias contains key which you (or the company?) use to sign a release version of apk Sep 26 10:40:12 adq: fair enough, I'll stick with the getWindow() that's working perfectly :D Sep 26 10:40:12 ruicruz, https://developer.android.com/distribute/googleplay/start.html & https://developer.android.com/studio/publish/index.html Sep 26 10:40:14 yes Sep 26 10:43:33 adq, first link is done, i've (the company) a dev account. the second link points to "build *my* app" but i've done it with appnotch, witch is a do it yourself, and at the end then only ask me for this 4 values I talk earlier. my question is if I can generate them from android studio, since I do not have the app (the "code") because i was not the one who created it. Sep 26 10:44:03 that was a question... -> ? Sep 26 10:44:04 :p Sep 26 10:45:00 ruicruz, check the sub articles of the first link, like the last one "sign your app", but basically Ashiren explained to you already Sep 26 10:45:31 they want the keystore and the credentials associated to the key of your app so they can resign it, it seems Sep 26 10:45:50 are they modifying your apps or something? Sep 26 10:46:45 you can generate from AS by the way, when you do "generate signed apk" Sep 26 10:47:28 ah, got it adq. found out just now that Ashiren is talking after creating a project. :) i think im in the right path Sep 26 10:47:40 they are not modifying it, they're literaly "creating it" Sep 26 10:47:48 uh ok Sep 26 10:48:20 ok, will go from here and see if I have any more questions. but to the both of you, a big thank you! :) Sep 26 11:05:19 how to print print string value and the update string value in the textview Sep 26 11:36:53 effin admob mediation Sep 26 11:53:00 Hi, does people know why android studio default install pull qt5.5 ? Sep 26 11:53:14 tools/lib64/qt/lib/libQt5*.so (on linux x86_64) Sep 26 12:03:51 Hi all, I need some help with a very basic problem, that after a lot of search I still can't resolve. Any help would be appreciated Sep 26 12:04:11 I'm importing some custom libs in my project and some of them use SLF4J Sep 26 12:04:33 custom libs are java jar libs Sep 26 12:04:53 when I deploy and run my app on a phone I get the following exception Sep 26 12:04:54 java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory Sep 26 12:05:10 I have deliberately not packaged any dependencies in my custom lib jars Sep 26 12:05:30 and have added the slf4j and logback dependencies in my build.gradle Sep 26 12:05:57 but I just can't understand why the apk doesn't include the slf4j and logback jars Sep 26 12:09:18 ayor: are you using gradle? or just standard building? Sep 26 12:10:23 sdousley, for my java libs, i'm using maven for android i'm using gradle Sep 26 12:11:47 sdousley, in intellij, I do see that logback and slf4j have been imported corrected (external libs) Sep 26 12:12:03 and I also double checked that the LoggerFactory class is there Sep 26 12:12:34 but for some reason when I deploy the apk on my phone, the packaging seems to not include the jars Sep 26 12:13:28 I managed to get it working only once, and I can't remember what task I ran in gradle, and I have tried running the lifecycle tasks Sep 26 12:13:42 both from the root build.gradle and from the build.gradle in the app module Sep 26 12:14:02 my app, which I have in IntelliJ, builds fine, and includes the libs that are defined in build.gradle. Sep 26 12:14:04 assembleDebug and assemble, build clean etc .. Sep 26 12:14:09 that pulls stuff in from Maven repo's Sep 26 12:14:48 yes, so my other custom libs that are deployed in my local repo are correctly imported, the problem is with this slf4j and I just can't get it to work Sep 26 12:14:54 lost soo much time on this Sep 26 12:18:40 sdousley, have you created and android application configuration and selecting your main class, and device to deploy? Sep 26 12:19:01 sdousley, or are you using a gradle task manually to install? Sep 26 12:19:30 sdousley, deleted my .gradle dir hoping it was a cache problem but that didn't help either Sep 26 12:26:26 hi Sep 26 12:26:57 Is it bad practice to do things which affect the view/routing outside Activities? - http://stackoverflow.com/q/39702070 Sep 26 12:30:00 AlecTaylor: if you want to remove that kind of code from that class maybe you could inject a callback so that that class is unaware of what will happen in that condition. Sep 26 12:30:25 I dont' see anything wrong with what he's doing Sep 26 12:31:01 Arancio: I know I CAN do it, I want to know if I SHOULD do it Sep 26 12:31:03 It might be confusing to whatever might get the super() call, but I can think of no other likely sideeffect Sep 26 12:31:08 er can't think of Sep 26 12:31:18 @#!$@# too much morning not enough caffiene Sep 26 12:32:09 Arancio: Or if I should explicitly push all `setText` and `startActivity` style invocations to the class that extends from Activity Sep 26 12:34:28 I don't think that's would be the correct reason to relocate that functionality Sep 26 12:35:07 AlecTaylor: what that class do? Sep 26 12:35:45 AlecTaylor: what does that class do? Does it make sense for it to know about a setting text in a view or about an Activity? Sep 26 12:35:47 Arancio: So I might have a LoginActivity.class which extends AppCompatActivity and handles stuff Sep 26 12:36:12 That's what I'm trying to figure out, common design principles for doing this Sep 26 12:37:19 AlecTaylor: if I make a networking class I expect it to do networking on every computer computer supporting the networking stack that I'm using. Nothing else. It should be usable for a command line utility or from a Windows application (provided it has the right libraries). I would remove the UI code from it for those reasons Sep 26 12:37:20 I suspect it would make more sense to have the code in it's own method, and just call _that_. I'm not sure why you'd be _wanting_ to call startActivity in a class but passing arguments to it via Intent Sep 26 12:38:17 That piece you could call from the onCreate of the Activity to catch the intents Sep 26 12:38:41 er... other way around. Catch the intents in onCreate and pass them to the function as args Sep 26 12:38:52 ayor: I just use Shift-F10 in IntelliJ and it builds/deploys to my phone plugged in via cable. Sep 26 12:39:27 ayor: maybe if you could pastebin your app level build.gradle Sep 26 12:42:04 Dagmar, Arancio: Yeah that's what I suspected. So in my 401 catcher I should just return that tuple? Sep 26 12:42:21 Heck you can pass it over as a bundle if you like Sep 26 12:42:21 PS: Can one of you add that as an answer so I can accept? Sep 26 12:42:38 Dagmar: Of course I can, the question is SHOULD I, not CAN I Sep 26 12:43:12 There's not a lot of sense in calling startActivity from within the same Activity, since the arguments you can pass it are fixed and everything else involves some overhead Sep 26 12:43:32 AlecTaylor: either your method returns an error condition, if it can. If it's an internal method it should invoke a callback. (I don't have a SO account) Sep 26 12:43:53 You can certainly call thingWotDoesSomethingWithTheResponse() from both startActivity and anything else in the package Sep 26 12:45:26 I'm still trying to work out precisely why startActivity might be called unless the activity is actually starting Sep 26 12:46:39 Ugh. I *really* need to ingest this freakin' caffeine. Scratch what I just said. The verbiage of the question was throwing me Sep 26 12:48:16 Things i said which _weren't_ insane... startActivity is pretty much normally _how_ you pass intents to an Activity, and it doesn't matter WTF you call it from Sep 26 12:48:42 There's simpler ways to do it if you're trying to have the Activity call _itself_ tho Sep 26 12:49:37 I call context.startActivity from classes which don't extend anything. There's no issue with it Sep 26 12:50:21 Yeah well this is the first time I've called startActivity from outside the Activity class Sep 26 12:50:43 Dagmar - And my suspicion is that I'm not meant to call it outside the Activity class, because it breaks some design principle Sep 26 12:50:43 ...of course they're starting _other_ Activities, not anything inside the same package at all. There's broadcast receivers and so on for _that_ kind of thing Sep 26 12:51:03 AlecTaylor: How? startActivity is literally how you launch new activities Sep 26 12:51:39 Dagmar: But should I be returning an Intent from this utility function, and actually call startActivity from the Activity class? Sep 26 12:51:41 hi, so I'm using AndroidStudio, I create a new android project, then Add Module > Android Library, they're both separate, I add a class to my library, how do I use it in my app? Sep 26 12:51:53 Dagmar: Or is it okay to call it from the utility function? Sep 26 12:52:02 Like a button that the user pushes to launch another application... Doesn't need to be in a class that extends anythinhg... it just needs a launch intent attached and off you go Sep 26 12:52:58 It's okay to call it from anywhere, including a Service, or some random class common to your package as far as I know Sep 26 12:53:18 it's not defined Sep 26 12:53:24 Dagmar: So it's not breaking the 'Google book of design' principle? Sep 26 12:53:28 and I can't import a package? Sep 26 12:53:36 (or whatever) Sep 26 12:53:44 I mean Sep 26 12:53:55 Considering that the Google docs are where I learned how to launch things with intents and the example was doing it in a "plain" class? I think it's pretty fine Sep 26 12:54:15 My main app is com.name.mainApp, while when I added the new module of the android library, it created the package com.name.myLib Sep 26 12:55:21 I'm simply following a tutorial step by step but I can't call my method from the library class Sep 26 12:55:23 https://xinyustudio.wordpress.com/2015/12/31/step-by-step-guide-for-developing-android-plugin-for-unity3d-i/ Sep 26 12:56:28 "In the Helper class add a function DoSthInAndroid()" this one I can't call from the main app Sep 26 12:56:47 Didja make it public? Sep 26 12:56:54 Yeah Sep 26 12:56:57 Probably a dumb question Sep 26 12:57:01 Here's my layout Sep 26 12:57:30 http://puu.sh/roohK/6f621d412f.png Sep 26 12:59:11 sdousley, yes, that's how I do it too. I'll send over the build.gradle link in a bit, trying something brb Sep 26 12:59:42 ranbox2d: in your main app gradle Sep 26 13:00:21 do you have compile project(':the_created_module') Sep 26 13:01:32 ranbox2d: That _should_ be working as far as I can tell Sep 26 13:01:39 I don't think so Ashiren Sep 26 13:02:00 then likely your main app doesnt see the module Sep 26 13:02:08 Only thing I can think of that would break it is if the other jar wasn't landing in the apk Sep 26 13:02:20 it should be under dependeencies {, under compile fileTree(...) Sep 26 13:02:56 compile 'com.name.mylib' Sep 26 13:03:02 add this line to dependencies? Sep 26 13:03:42 It wasn't in there already? Sep 26 13:03:57 no? Sep 26 13:04:00 Should it be? Sep 26 13:04:19 I just right clicked my main app and added the android library module Sep 26 13:04:38 add compile project(':gallery') Sep 26 13:04:43 replace gallery with name of your module Sep 26 13:05:14 sync gradle and see the magic Sep 26 13:06:30 wow, thanks! Sep 26 13:06:31 How can I check if a string variable is blank? I'm trying if(var.equals("")) but getting exception "Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)'" Sep 26 13:06:50 I think you just saved me from falling in a very deep hole of frustration later on Sep 26 13:08:28 sdousely: On a null object reference? Sep 26 13:08:35 sdousley, here you go http://pastebin.com/qtPeYU7t Sep 26 13:09:14
