Spot the deliberate bug (tutorial) Posted: 02 Mar 2019 07:27 AM PST Just put a tutorial on dev.to explaining a very common way that android UI code can become inconsistent, and a technique for dealing with it. https://dev.to/erdo/tutorial-spot-the-deliberate-bug-165k the full kotlin app code is here if anyone wants it ​ submitted by /u/erdo9000 [link] [comments]

Android Studio 3.3.1 Using way too much RAM Posted: 02 Mar 2019 10:32 AM PST Ive been using AS daily for past 6+ months and I never had such big ram problems with it. I never used emulator so it would usually use less than 2GB ram so I never had any problems (my RAM is 8GB). Now suddenly its pretty much always using 3GB ram which kinda kills my whole system. If I restart it, it gets fixed for a while but itll go up again and starts lagging it self and the whole windows. ​ Is anyone else experiencing this too ? or is it just me? submitted by /u/YasanOW [link] [comments]

Bringing some Kotlin goodness to Java Posted: 02 Mar 2019 09:27 AM PST This is for all those poor people (such as myself) which have to use java in their job. I ported the following functions from kotlin (using a wrapper): .let { } ?.let { } .also { } ?.also { } .takeIf { } ?.takeIf { } .takeUnless { } ?.takeUnless { } ​ Some simple usage example: ​ String amountString = "23782"; Integer number = take(amountString) .also((amountStr) -> System.out.println("String Amount is" + amountStr)) .takeIf((amountStr) -> amountStr.matches("[0-9]+")) ._let(Integer::parseInt) // _let is equivalent to ?.let { } ._also((amount) -> System.out.println("Non-null Integer Amount is" + amount)) .unwrap(); ​ It's not as pretty as kotlin, but (I hope) it's still a good addition to java. Opinions/Questions/Requests are more than welcomed! ​ P.S.: The docs, code and installation can be found here: https://github.com/AlexDochioiu/K2J-Compat Later Edit: Replaced it with variable names for lamdbas submitted by /u/jeefo12 [link] [comments]

Can't update recyclerView from another activity Posted: 02 Mar 2019 12:07 PM PST What i have is the MainActivity that has the recyclerView and it is going to show a set of cardViews of anime series, what i want to do is that a user clicks on a floating button on mainActivity and go to another activity where the user has to add a name and a number of visits, in order to create another anime series. ​ I have tried several things that i have found on internet but no luck. What i have done is this: ​ https://pastebin.com/c5cGhqHm ​ ​ SOLVED: ​ It was solved using cryptoz answer. submitted by /u/Filmboycr [link] [comments]

What's a good place to learn UI? Posted: 02 Mar 2019 06:05 AM PST I've been in the Android world for a while and I think I can make some pretty UI, but sometimes I struggle to make on and I can't really create something that I myself can call beautiful. ​ So, is there any good course out there on how to make a beautiful, stunning UI? I don't really care about UX here, I just want it to be wonderful (even if it becomes unusable). submitted by /u/Tinytitanic [link] [comments]

Google Android Recertification Posted: 02 Mar 2019 03:20 PM PST Hi there has anybody gone through the process of doing a Google Android Recertification? I seem to remember that the certification is good for three years, and since I'll be coming upon 3 years shortly I'm starting to look into it. I haven't received any recertification notices from Google, but I do see that the certification now covers some of the Jetpack APIs like Room, etc. Anyone have experience with this? submitted by /u/misterbonger [link] [comments]

App went from 9-12k daily installs to 100~ daily installs in one day Posted: 01 Mar 2019 11:48 PM PST I just noticed a sudden decrease in revenue, i logged on console only to see that my main app which had 9-12k daily downloads on average for past 2 years, suddenly decreased downloads to around 100. Downloads went from 12000 to 100 in one day, on 13th February to 14th February. What the actual f? Has anyone had this issue before? Note that app is working as usual. Nothing major changed, no sudden increase in crashes or something like that. App just got killed. Does anyone have any similar issue? submitted by /u/SabroanX [link] [comments]

Android studio find special character in path? Posted: 02 Mar 2019 11:20 AM PST Does anyone know if there is a way to find a "." in path in android studio? I was recently doing a refractor and had something along the lines of valueA = ObjectA.valueA I wanted to find and replace in path all instances of just ".valueA" but the period wasn't being included in the search. Kind of thinking this might not be possible to search, but figured I would ask. Also related is that is really hard to search stackoverflow and google about punctuation haha. submitted by /u/shlopman [link] [comments]

What are the different ways by which an Android can play an audio? Posted: 02 Mar 2019 03:53 AM PST I was recently doing a research on Android audio. And i wanted to know which libraries are responsible for audio/video play. As far as i know media player and exo player are the two libraries which can be used to play user variety of audio/video files, application's raw/asset files and online stream files. Are there any other sounds beside system sounds which i forgot or other libraries which are also used for media playing? And also what about these system files? Can we access system ringtones and notifications/ alarm tunes in a normal, non-rooted phone? I remember that my previous phone's music player (android kitkat maybe) was able to pick some system ringtones. Is it still possible now(android lollipop nd above) ? Although i guess music in Android assets or raw files of some other app won't be accessable to my app, unless i am having screen record permissions? submitted by /u/appdevtools [link] [comments]

How to remove app from playstore? Posted: 01 Mar 2019 10:33 PM PST I had developed a SMS automation app and now the because of SMS permission policy It nearly unusable . So it doesn't make sense of removing a app SMS permission because app totally depend on SMS activities. How can I remove app from playstore and what are the alternative stores to upload application submitted by /u/ishanfx [link] [comments]

Kotlin or java help Posted: 02 Mar 2019 12:28 AM PST Hey guys, This is my first post in this sub ( English is not my mother tongue, so excuse me if I make any mistake). I have a bachelor degree in Computer science and the last year I started learning about android with the Udacity courses. I really liked it and started learning more and creating several small projects with java. Today, I had an interview at a startup and they offered me a position as a trainee since I had no work experience in the field and because they work with kotlin only. And here comes my concern : I love android but, should I start at that startup and learn kotlin and give up java ? Because so far as I know there are a lot more jobs at the moment with java then kotlin such as backend etc. My other concern i be able to switch career in the future because I like to have alternatives since I'm a beginner in the software industry. Every advice is welcome, Thanks submitted by /u/caxaj [link] [comments]

Java -> Kotlin devs: how do you deal with no checked exceptions? Posted: 01 Mar 2019 04:08 PM PST I am learning Kotlin for fun and while I like the language overall, I am surprised by lack of checked exceptions. To illustrate my point, consider one case, you are fetching data from network and the fetcher throws various Network related exceptions, later someone adds a persistent caching layer and that adds IO related exceptions to the list, as soon as that person's code lands, the compilation fails, forcing someone to add handling for the new errors. One can also see the situation in reverse, where an exception is no longer being thrown, without checked exception, the dead code remains forever. Am I missing something? submitted by /u/ashishb_net [link] [comments]

Help with animations. Posted: 01 Mar 2019 05:40 PM PST Hey all!I've been developing on Android for quite a while now and recently I've had the realisation that I'm seriously lacking in the animations and feel department. I've always found it a bit hard and unintuitive to create and add animations to android apps. And it's not like I haven't researched this topic a ton.. Anyway, I recently had a look at 2dimentions/flare - looks pretty sweet but it's made for flutter and I'm doing Java/Kotlin... Can I get a few recommendations on good tutorials or starting points on SVG animation? I've watched the Animation intro of the Android Summer Dev a couple of times now, and I did learn how to do some basic property anims, but nothing complex.. Don't mind getting my hands durty in adobe either. I'm open to any kind of suggestions - I just want to make my future apps more 'flutey' and alive What are you peeps using and what would you recommend me? - (for both creating the animation and adding it to your app) ​ Thanks! submitted by /u/TheWalkingFridge [link] [comments]
