Private Boolean Isrunningforeground (context context) {

Activitymanager am = (activitymanager) context.getsystemservice (Context.activity_service);

ComponentName cn = Am.getrunningtasks (1). Get (0). topactivity;

String currentpackagename = Cn.getpackagename ();

if (! Textutils.isempty (currentpackagename) && currentpackagename.equals ("Com.uvisioncctv.FirstStart"))// This is my package name, the main package name.
