How can I convert a stack trace to a string?

Question

What is the easiest way to convert the result of Throwable.getStackTrace() to a string that depicts the stacktrace?

Answer 1

If you are developing for Android, a far easier way is to use this:

import android.util.Log;

String stackTrace = Log.getStackTraceString(exception); 

The format is the same as getStacktrace, for e.g.
