I2.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK); // | Intent.FLAG_ACTIVITY_NEW_TASK);

Solution 1

if you want your activity to be in background add this line in the oncreate of activity

moveTaskToBack(true);

Solution 2

You can use this line in your onCreate() method:

moveTaskToBack(true);

Solution 3

You don't want to start an Activity in the background. There are better ways to do what you want. You can have your Activity register to receive the broadcast Intent, for example. It will get the call to onReceive() even if it is in the background. You can determine if your Activity is in the background by setting a variable to true in onPause() and to false in onResume(). Then in onReceive(), if the variable is true you are in the background.
