When I run my app directly from Android Developer Tools (ADT), it works fine. However, when I export it to an APK file and install it, I get the following error:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{my.app/my.app.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "my.app.MainActivity" on path: DexPathList[[zip file "/data/app/my.app-2.apk"],nativeLibraryDirectories=[/data/app-lib/my.app-2, /vendor/lib, /system/lib]]

The problem seemed to be a bug in ADT. Manually doing a clean via Project -> Clean and then re-exporting the APK fixed the problem.

First register your app on firebase console and follow the steps mentioned there remember to put the google-service.json file parallel to the app folder in your project.
I got this crash report from many users.

Anyone have any idea what to do?
Never used unity3d... also I don't know what's in your gradle files, so can't really say unless you give more information. However, you could try cleaning your project and rebuilding it. Go to Build -> Clean Project or use gradlew clean if you are comfortable with the command line.
I have got a problem involving ClassNotFoundException. When i "Run as
android application" from eclipse it works fine, but when i download
it from Google Play (same source code but "Exported as signed app") it
crashes with the following stacktrace:

Try Cleaning the project and export it once more to google play.
I have an app that I just received a crash report for. I don't have the full stack trace with me right now, but it was from ActivityLoader.performLaunchActivity.
The class it is trying to launch is android.support.v7.widget.TestActivity. I certainly never try to load this activity anywhere in my app.
The device is a Samsung Galaxy Nexus running 4.1.1 rooted. The stacktrace looked normal to me (no xposed or anything like that).
Anyone ever see anything like this?

After posting this in the Android issue tracker, I've gotten a response saying that it was an issue with Gradle that has been resolved, and will be reflected in the support libraries when they're updated.
This morning I have received from my BugTracker system the same exception in few seconds for several devices
Google Nexus 5 with Android 4.4.2
Galaxy Nexus with Android 4.1.1
Looks like someone have extracted the APK and installed in some simulator (I suspect this also because the reported screen size is 480x800 that is not a screen size of nexus 5.
So I think that this is not a real exception (or at least an exception thrown by our application) but some test made by someone.
The exception received is
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{it.frusso.mdpalette/android.support.v7.widget.TestActivity}: java.lang.ClassNotFoundException: Didn't find class "android.support.v7.widget.TestActivity" on path: DexPathList[[zip file "/data/app/it.frusso.mdpalette-1.apk"],nativeLibraryDirectories=[/data/app-lib/it.frusso.mdpalette-1, /vendor/lib, /system/lib]]
