in activity details:

public static activitya instance = null; public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     instance = this; }  @override public void finish() {     super.finish();     instance = null; } 

then in acitvity login:

public void oncreate(bundle savedinstancestate) {     if(activitya.instance != null) {         try {               activitya.instance.finish();          } catch (exception e) {}     } }
