I'm using Android Studio 4.1.3 in Windows 10, and I'm having problems with debugging.

The app runs ok if not debugging or using Resume Program while debugging, but if try step debug (over, into, out) it crashes.

It occurs with all apps and with all platforms tested (real devices and emulations) and in all lines of code (in first line of onCreate of the MainActivity for example).

Already tried to delete all break points, cleaning the build, but not could find out how to disable Instant Run in this version.

Have anyone any idea? Thanks.

  • Does this answer your question? [Android app crashes when launched in debug mode](https://stackoverflow.com/questions/40618803/android-app-crashes-when-launched-in-debug-mode) – Thelouras Apr 24 '21 at 14:40
  • Hi Thelouras, this doesn't answer, application runs well in debug mode and crash ONLY if step into/over are used (breakpoints works fine with Resume Program too). Thanks. – sgm Apr 24 '21 at 14:49

Not sure if is really a answer, but...

The problem is somehow related with APIs from 23 (not tested bellow it) through 26. In none of this API the debugging (Step-Into, Over) works, not in emulated devices and not in physical devices.

APIs from 27 works fine.

Note that the APK of application is 23 and debugging with API 23-26 works with Run and breakpoints to get inside methods... just a pain place dozens breakpoints....

  • Change compileSdkVersion android targetSdkVersion lower than 30, like 28 or much lower.
  • Then build and debug.
    • It works well.
  • After that, you can recover the compileSdkVersion android targetSdkVersion you have set before.
    • It works well too.
