How do I obtain crash-data from my Android application?

Question

How can I get crash data (stack traces at least) from my Android application? At least when working on my own device being retrieved by cable, but ideally from any instance

Ok, well I looked at the provided samples from rrainn and Soonil, and I found a solution that does not mess up error handling.

I modified the CustomExceptionHandler so it stores the original UncaughtExceptionHandler from the Thread we associate the new one. At the end of the new "uncaughtException"- Method I just call the old function using the stored UncaughtExceptionHandler.

In the DefaultExceptionHandler class you need sth. like this:

public class DefaultExceptionHandler implements UncaughtExceptionHandler{
  private UncaughtExceptionHandler mDefaultExceptionHandler;

  //constructor
  public DefaultExceptionHandler(UncaughtExceptionHandler pDefaultExceptionHandler)
  {
       mDefaultExceptionHandler= pDefaultExceptionHandler;
  }
  public void uncaughtException(Thread t, Throwable e) {       
        //do some action like writing to file or upload somewhere         

        //call original handler  
        mStandardEH.uncaughtException(t, e);        

        // cleanup, don't know if really required
        t.getThreadGroup().destroy();
  }
}

With that modification on the code at http://code.google.com/p/android-remote-stacktrace you have a good working base for logging in the field to your webserver or to sd-card.
