Answer Source

you do not need to start activity for StoreDetail as it is a subclass of Fragment not Activity.This is the reason that your app is crashed.

Now moving to your question if you want to go back to the fragment from the activty : Stock INFO you just need to call finish() it will finish the current activity(Stock Info) and the fragment which is in background will be resumed.I had same problem and solved by this way .This is the onCreate Method of Activity(in your case it is for StockInfo class).Have a look:

public void onCreate(Bundle savedInstanceState) {

    this.setmCallBack(new IResultCallback() {
        public void result(Result lastResult) {

            if (lastResult!=null) {
                finish();// by this line I have killed the current activity


            Toast.makeText(getActivity(), "NotScan: ", Toast.LENGTH_SHORT).show();
