I have an alarm project, on AlarmReceiver I have this code.

the error is the flag is cannot be used, Android Studio say FLAG_ACTIVITY_NEW_TASK is not listed in usable Intent Flag.

how to fix that?

Answer 1

Try this :

Intent myIntent = new Intent(context, DoSomething.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Then in your PendingIntent

 PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, myIntent, 0);

Answer 2

You put the flag in the wrong place. Where you put it only flags for PendingIntent creation go.

You need to do this instead:

myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Note (from the documentation ): PendingIntent flags

May be FLAG_ONE_SHOT, FLAG_NO_CREATE, FLAG_CANCEL_CURRENT, FLAG_UPDATE_CURRENT, or any of the flags as supported by Intent.fillIn() to control which unspecified parts of the intent that can be supplied when the actual send happens.
