I have gone through android docs on FLAGS and Affinity (Link) and tried different combinations that I thought would help achieve my requirement but it seems that I'm missing something.
I need to initiate activityA from from BroadcastReceiver and then finish activityA and start activityB. so when the user presses back it wont go back to activityA; when user presses back on activityB it will stop the activityB and it will go to back stack however when the user opens app back from task manager it will start up from activityA.
Note: this does not happen when there is another activity of the app in the background.(only happens when the app is entirely force closed/killed).
also when user presses home button in activityB it behaves as intended.
I use the following code to lunch activityA from BroadcastReceiver.
Intent intent = new Intent(context, ActivityA.class);
intent.putExtra(EXTRA_TAG, new Gson().toJson(remoteMessage));
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_SINGLE_TOP|Intent.FLAG_ACTIVITY_CLEAR_TASK|Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
I use the following code to lunch activityB from ActivityA.
Intent intent = new Intent(this, ActivityB.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_SINGLE_TOP|Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_TASK_ON_HOME);
startActivity(intent);
finish();
Is there a different FLAG that I need to use to achieve this requirement?
