My Application Shuts Down with a Silent Error (AndroidRuntime: Shutting down VM)
MyApplication terminates silently. The last thing it prints is a tracelog from a function, then the Vm shuts down without any reference to my application.
This is the log snippet
05-17 15:25:28.294 4385 4385 D MyApplication: MyFunction()
05-17 15:25:28.294 4385 4385 D AndroidRuntime: Calling main entry com.android.commands.am.Am

05-17 15:25:28.546 4400 4400 D AndroidRuntime: Shutting down VM
The application continued running.
There's no clear indicator except the generic: 05-17 15:25:28.546 4400 4400 D AndroidRuntime: Shutting down VM

The error was caused by an StackOverflow in native code I wrote.
Stackoverflows shut down silently in Android Native Code, in contrast to segfaults and are therefore hard to find.
Locate the last working piece of code with Tracelogging / Logdebug or use the debugger of Android Studio and you will find the location of the bug.
The indicator for the silent termination is: "Shutting down VM"
05-17 15:25:28.478 4385 4385 D AndroidRuntime: Shutting down VM
05-17 15:25:28.526 4400 4400 D AndroidRuntime: Calling main entry com.android.commands.am.Am
05-17 15:25:28.546 4400 4400 D AndroidRuntime: Shutting down VM
The application continued running, because the code was executed within it's own process (via ProcessBuilder.command())
