How to get entire backtrace from Throwable ex

Question

I've implemented the following code to get crash details:

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
  @Override
  public void uncaughtException(Thread thread, Throwable ex) {
    Log.e(TAG, "Uncaught Exception!");
    StackTraceElement stackTraceElements[] = ex.getStackTrace();
  }
});

The problem I'm facing is, let's say two exceptions occur, RuntimeException which was caused by NullPointerException. In the above method, I'm getting trace for only RuntimeException. What should I do to get entire the back trace?

Use getCause() method

ex.getCause().getStackTrace()

Note that getCause() can return null. – Carnal Aug 10 '15 at 07:35
I looked into doc before posting, how silly of me, didn't notice this method! – Swapnil Bhoite Aug 10 '15 at 07:36

You can use the following.

StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
t.printStackTrace(pw);
sw.toString(); // stack trace as a string

This will give you the complete stack trace. For other ways of getting the same please go through this thread. Above has been copied from the same thread

This does work, but I wasn't looking for exact string, I wanted to format it my way and hence hence was looking for all `Throwable`s back traced. Thanks anyways! – Swapnil Bhoite Aug 10 '15 at 07:39
