Receiver not registered

Question

I have a progamm with async task and a broadcast receiver to send a result code, so that Asynctask will know that app is working. But it crashes, sayin the receiver is unreg

Answer 1

Because your broadcast receiver only created when (!mIsFresh).
So, in some case, your broadcast receiver is not instance because of mIsFresh.
Therefore, onResume register a null of broadcast receiver.
When onPause tries to unregister it, the error occur.

Answer 2

Try as follows...

    mRefreshReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {

            log("BroadcastIntent received in MainActivity");

        }
    }

In onResume()...

@Override
protected void onResume() {
    super.onResume();

    IntentFilter filter = new IntentFilter(DATA_REFRESHED_ACTION);    
    registerReceiver(mRefreshReceiver, filter);

}

In AsyncTask....

    Intent intent = new Intent(DATA_REFRESHED_ACTION);
    sendOrderedBroadcast(intent, null, new BroadcastReceiver() {

        @SuppressLint("NewApi")
        @Override
        public void onReceive(Context context, Intent intent) {

            log("BroadcastIntent received in MainActivity");

        }
    }, null, Activity.RESULT_OK, null, null);
}
