After sending the broadcast, the redirect activity problem torched over a day.

At first I thought it was a repeat broadcast. Didn’t solve.
Then see under Caused by: Java. Lang. An IllegalStateException: Can not perform this action after onSaveInstanceState
Life cycle issues. I know why
After the broadcast the activity is on the edge of being killed in some scenario, the system calls the onSaveInstanceState method, which calls the FragmentManager saveAllState method, saves the state of the fragment, and after the state is saved, the user actively calls onBackPressed, The method’s superclass super.onbackPressed determines if the FragmentManager has saved state and throws an exception for IllegalStateException if it has. Then the activity cannot be found when the broadcast is received
It’s easy: let me rewrite it
Override
protected void onSaveInstanceState(Bundle outState) {
// TODO auto-generated method stub
}
