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?

Answer 1

使用getCause（）方法

ex.getCause().getStackTrace()

Answer 2

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
