java.lang.NoSuchMethodError on Activity.showDialog (int, Bundle)?

Here is what LogCat says:

I get an error at this phrase: 

Bundle args = new Bundle();
args.putLong("id", ...);           //Some arbitrary value
showDialog(DELETE_DIALOG, args);

I have an onPrepareDialog method: 

@Override
protected void onPrepareDialog(int id, Dialog dialog, Bundle args) {
    switch (id) {
    case DELETE_DIALOG:
        AlertDialog log = (AlertDialog) dialog;
        final Bundle bundle = args;
        log.setButton(DialogInterface.BUTTON_POSITIVE, "Ok", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                long id = bundle.getLong("id");

                getContentResolver().delete(Tasks.CONTENT_URI, Tasks._ID + "=" + id, null);
                adapter.notifyDataSetChanged();
            }
        });
        break;
    default:
        break;
    }
}

What could be the problem?

Solution

  • Generally that means the class you compiled against and the class you're running against are different versions. The method you are calling was accessible to your compiler but is not available to the JVM at runtime.
