I've searched around for the solution and there are several related to ClassNotFoundException threads like this on SO. But I tried solutions provided there and nothing helped. So in my case when deploying app to a device directly from Android Studio it runs normally, although it crashes when installing from file: adb install app-debug.apk.

I do have that class MyApp in the project. That log doesn't make anything clear for me. I've noticed the problem after updating Android Studio to 2.3 and updating some dependencies in the project. Before it worked fine.
I will appreciate any help in solving this issue.
Edit:
After some trials I've found out that the way I create a build makes difference. If I build my project with Build/Build APK and adb install app-debug.apk it won't throw an exception. But every time I use Run/Run 'app' option to deploy the app to the device, installing apk created this way through terminal results in a crash with mentioned exception. Is it intended behaviour or a bug?
Also worth noticing that Build/Clean project fixes the problem for the next build.

It is an intended behaviour. If Instant run feature is enabled, AS would build a special kind of an apk, only with recent changes. So, in order to build an apk that is able to run with adb install app-debug.apk command one should build an apk with Build/Build APK.
