    This thread is for simple questions that don't warrant their own thread (although we suggest checking the sidebar, the wiki, our Discord, or Stack Overflow before posting). Examples of questions:

    • How do I pass data between my Activities?
    • Does anyone have a link to the source for the AOSP messaging app?
    • Is it possible to programmatically change the color of the status bar without targeting API 21?

    Large code snippets don't read well on reddit and take up a lot of space, so please don't paste them in your comments. Consider linking Gists instead.

    Have a question about the subreddit or otherwise for /r/androiddev mods? We welcome your mod mail!

    Also, please don't link to Play Store pages or ask for feedback on this thread. Save those for the App Feedback threads we host on Saturdays.

    Cheap phones to buy for testing?

    Posted: 15 Dec 2019 03:28 PM PST

    My app is nearly ready for production and I'd like to improve testing by buying a 3rd Android phone.

    I currently have a Google Pixel 4 and Samsung S8. What's a good 3rd phone to buy?

    Has anybody here ever used conversion to ConstraintLayout, and it worked fine?

    Posted: 16 Dec 2019 01:09 AM PST

    It seems to me that in almost all cases, the conversion makes a messed up result (Missing constraints, replacing of sizes,...).

    Did it work well for anyone?

    Or do you always do it all manually when you decide to convert?

    To me it seems to have a lot more issues than when converting from Java to Kotlin, for example.

    What is your opinion on real physical test devices vs emulators?

    Posted: 16 Dec 2019 07:53 AM PST

    What is your opinion on using real physical test devices for development or just emulators?
    I used to have a test device and then switched to emulators because they are much more practical, now I don't even use test devices because I find them annoying, they take up space on my desk, problems with cables, and doesn't really contribute to my productivity. The only positive side I see from using physical test device is UI scaling on various screen sizes.

    So what do you think? Does one need physical test device or are emulators sufficient?

    Why does my app not "forget" a class's variables after the activity that is using the class is destroyed?

    Posted: 16 Dec 2019 07:38 AM PST

    I have an app that has 2 activities.

    1st activity is just a menu that leads into activity 2 that has it's custom view classes.

    The custom view class has it's static and instance variables.

    When I back out from activity 2 into activity 1, then press a button that leads me into activity 2 again some of the values of the class is still remembered. Shouldn't all the values be forgotten when activity 2 gets destroyed because I backed out into activity 1?

    Is MVVM necessary?

    Posted: 16 Dec 2019 05:44 AM PST

    Ever since architecture component were released all I see is people hyping and talking about MVVM. But is it a necessity? I mean sure it might help in complex applications, but in simple small applications, I don't really think it's important to use mvvm.

    We used to android apps before architecture component without even thinking if it is MVVM or mvc or mvp. Also we can use for example Room database without making it mvvm.

    Benchmark Notebooks for using Android Studio

    Posted: 16 Dec 2019 01:42 AM PST

    Does anybody know a good way to benchmark the performance of a Notebook in combination with Android Studio? I am currently trying to find a way but in my current tests my 2015 Macbook is way faster than the newest 2019 16 inch Macbook which shouldn't really be possible. But I guess it is really dependent on the Android Studio configuration, Gradle caches, etc.

    Is there a way to build a project with completely the same conditions without too much effort?

    When developing commercial Android libraries, Kotlin or Java ?

    Posted: 15 Dec 2019 10:10 PM PST

    Hello all,

    I know there have been many discussions/blogs about pros and cons of Kotlin or Java, and most of them focus on developing Android Application perspective.

    But how about when developing commercial Android libs ? Our 80% clients are still using Java to build the Android Apps with the libs we provided. We are currently providing Java libs but will have new ones with new functions. I'm not sure if it is risky to totally use Kotlin in our new lib for the clients ?
    On the other hand, I observed that Google's many AndroidX libs are still programmed in Java and they work well in Kotlin Android Apps. It seems to me that lib in Java could be a safe choice for clients no matter what language they use ?

    I personally wanna to use Kotlin, but it is the commercial use...
    So the compatibility of APIs is the priority for our clients and us.

    Thanks and any feedback will be appreciated :)

    Your AdSense account has been terminated.

    Posted: 16 Dec 2019 03:40 AM PST

    Oh my,

    did anyone here received a similar notice and were you guys able to get things resolved positively ?

    The email I received said "INCENTIVIZED TRAFFIC:" but I don't do hacks like this. I always follow all rules and recommendations as good as I can and stay away from ANY blackhat type operation.

    I have apps with AdMob and some very very small blogs with AdSense. Of course the email did not contain anything else I could go by.

    Me == devastated :(

    How can I prevent my fullscreen app from switching to lower resolution on Galaxy S8?

    Posted: 15 Dec 2019 06:56 PM PST

    My Galaxy S8 has 3 screen resolutions 1480x720, 2220x1080 and 2960x1440.

    I always have the highest resolution selected in my settings.

    A while ago when I started to develop my game I remember that Android respected my setting and I actually was working with the selected resolution. But I eventually abstracted away from that and these numbers stopped mattering much. Until I checked now. And I'm reading 2220x1080. Even though I clearly have 2960x1440 selected. That's crazy. Switching to 720p does switch in-app resolution. But switching between 1080p and 1440p has no effect on my game, it stays 1080p.

    Normal Review / Download rate

    Posted: 15 Dec 2019 01:45 PM PST

    I just saw a new app with 10k+ downloads (Less than 50k) and almost 2k reviews whereas my app has almost 150k downloads and only 1200 reviews. The other app has nothing special and that's why i think those could be fake reviews. Both apps have 4.5+ score. What do you think?
