Activity excludeFromRecents not working on Android 5.0

Question

I'm trying to finish an activity and not have it on the recents. The following code seems to work on KitKat but not on lolipop, as the activity always shows on the recents.

intentInvite = new Intent( context, OnInviteActivity.class );
intentInvite.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intentInvite.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intentInvite = createInviteIntent( intentCloud, intentInvite );
context.startActivity( intentInvite );

AndroidManifest.xml

<activity android:name=".OnInviteActivity"
          android:label="@string/app_name"
          android:excludeFromRecents="true"
          android:noHistory="true"

Answer 1

Try adding an unique taskAffinity:

<activity android:name=".OnInviteActivity"
          android:label="@string/app_name"
          android:taskAffinity=".OnInviteActivity"
          android:excludeFromRecents="true"
          android:noHistory="true"

Answer 2

https://stackoverflow.com/a/27633500/1269737 - that's well known Android Issue.

This can be done programmatically

ActivityManager am =(ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
if(am != null) {
    List<ActivityManager.AppTask> tasks = am.getAppTasks();
    if (tasks != null && tasks.size() > 0) {
        tasks.get(0).setExcludeFromRecents(true);
    }
}

If Task Root Activity is excluded from recent, all activities in this task will be excluded too.
