I have an app that runs perfectly on some phones (All samsung Galaxys, some
LGs) and fails on an HTC ONE X, and an LG G2.
The app has a MainActivity, a Flashlight activity, a broadcast receiver,
and an intent service. The app can run in two different modes.
Mode 1: The user clicks on the icon and the mainactivity runs - when this
happens, the MainActivity immediately runs the Flashlight activity and
calls finish. The app functions as a flashlight program.
Mode 2: The broadcast receiver receives a Google Cloud Message and runs the
intent service which loads up an extra bundle and runs MainActivity.
MainActivity detects the extra and does NOT run FlashLight but instead
does some other work.
The problem is with Mode 2 on an HTC ONE X or LG G2, when the intent
service runs MainActivity, the onStart event is triggered in the FlashLight
activity showing the flashlight screen. As expected, MainActivity
functions perfectly - the problem is just that the FlashLight screen shows.
This is the code the intent service uses to start MainActivity...
Intent intentHome = new Intent(GlobalStuff.GCT,MainActivity.class);
intentHome.putExtra("whattodo", "presence");
intentHome.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
GlobalStuff.GCT.startActivity(intentHome); //GlobalStuff.GCT is app context
This is the app manifest file...
