Android - java.lang.IllegalArgumentException Erron when creating Dialog on 2.1 and low android

Question

I\'m getting the below error message from phones that are SDK version < 8. I just released this app on the android market and prior to release my test phones were a HTC Thun

Had the problem also and solved it with the following:

-Don't return a null Dialog in method: protected Dialog onCreateDialog(int id)

In Android 2.1 in Activity.java the error was raised on line 871.

private Dialog createDialog(Integer dialogId, Bundle state) {
869         final Dialog dialog = onCreateDialog(dialogId);
870         if (dialog == null) {
871             throw new IllegalArgumentException("Activity#onCreateDialog did "
872                     + "not create a dialog for id " + dialogId);
873         }
874         dialog.dispatchOnCreate(state);
875         return dialog;
876     }

If you look in later Android there is a check for a null Dialog and it's handeld with a return. So here it works.

-Don't use Bundle (changed in API8):

protected Dialog onCreateDialog(int id, Bundle bundle);

use:

protected Dialog onCreateDialog(int id);

-I also used the following check (had a special case with a custom dialog):

    if(Build.VERSION.SDK_INT <= Build.VERSION_CODES.ECLAIR_MR1) {
        return dialog;
    } else {
        return null;
    }

Maybe it helps someone...
