I know this question is a bit old, but for future references and googlers, here is a complete answer from another, hard to find, stackoverflow question: Android App Restarts upon Crash/force close
create a class used to handle unCaughtException
public class MyExceptionHandler implements
java.lang.Thread.UncaughtExceptionHandler {
private final Context myContext;
private final Class<?> myActivityClass;
public MyExceptionHandler(Context context, Class<?> c) {
myContext = context;
myActivityClass = c;
}
public void uncaughtException(Thread thread, Throwable exception) {
StringWriter stackTrace = new StringWriter();
exception.printStackTrace(new PrintWriter(stackTrace));
System.err.println(stackTrace);// You can use LogCat too
Intent intent = new Intent(myContext, myActivityClass);
String s = stackTrace.toString();
//you can use this String to know what caused the exception and in which Activity
intent.putExtra("uncaughtException",
"Exception is: " + stackTrace.toString());
intent.putExtra("stacktrace", s);
myContext.startActivity(intent);
//for restarting the Activity
Process.killProcess(Process.myPid());
System.exit(0);
}
}
Then in every thread (usually you have just one, unless you start a new thread (Async or ... , ofcourse you know about threads if you are able to make new ;) ), set this class as the DefaultUncaughtExceptionHandler
Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this,
YourCurrentActivity.class));
Remember though!
Do it in the very last step of developing your application, you HAVE to at least try handle all of your exceptions one by one before leaving them for DefaultUncaughtExceptionHandler
