This message means the app threw an unhandled exception and the process was terminated by Android. As notes, there are not enough details to diagnose the problem; as suggested, the hidden stack trace in Logcat is the key to a concrete fix.

Steps that reliably find the cause:

  1. Run the app from Android Studio (device or emulator) with USB debugging enabled.
  2. Open Logcat, set the filter to the app package name, clear logs, then reproduce the crash.
  3. Locate the first "FATAL EXCEPTION" / "AndroidRuntime" block and copy the entire stack trace beginning at that line.
  4. Inspect the first stack frame that belongs to the app package — it shows the class, method and source line to open in the IDE.

Common causes and quick checks:

  • NullPointerException: view binding before setContentView, wrong layout, or missing findViewById.
  • InflateException / Resources.NotFoundException: malformed XML or missing resources.
  • Security/Permission exceptions: missing manifest entry or runtime permission on Android 6+.
  • NetworkOnMainThreadException: network work on the UI thread.
  • ProGuard/minify: missing keep rules causing NoClassDefFoundError in release builds.
  • Fragment/Activity lifecycle mistakes (transactions after onSaveInstanceState).

Example stack-snippet to look for:

FATAL EXCEPTION: main
Process: com.example.myapp, PID: 1234
java.lang.NullPointerException: Attempt to invoke virtual method '...' on a null object reference
    at com.example.myapp.MainActivity.onCreate(MainActivity.java:42)

Helpful items to include when requesting assistance: the full "FATAL EXCEPTION" stack trace, the few source lines around the reported file:line, the AndroidManifest activity entry, app-level build.gradle, device or emulator model and API level, and exact reproduction steps. Avoid posting secrets or entire projects; a minimal reproducible example is best.

Just think about this from my viewpoint for a moment.

You have something called myapp that has stopped. Do you know how many programs called myapp you can find on Google? Maybe this isn't even any of those, but something you wrote. I don't know if it's C<something>, Java, or whatever. I don't know if it's Windows, Mac, IOS, Android, Linux. I don't know what you were doing with the program or what input you may have provided. I don't know if it has a database and/or depends on an internet service.

And you think I can tell you how to solve it?

Guessing from the "MyApp" and the context and the error message that the OP is using Android Studio to develop an Android Application that is crashing. This is only an educated guess. OP, if true, see this link...

It's a pretty useless error message, but that's because it's intended to be seen by users, not developers. There is an un-displayed stack trace that may hold your answer, or at least part of it. Your app had an exception that wasn't handled somewhere and it "crashed". See the link above for details on how this all works and how to view it.

And James is correct. Details, details, details. All sorts of things could have caused this, so we can't say "You divided by zero on line 13" because you've given us none of those details. Find that stack trace and follow it.
