final ActivityManager manager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);

for (ActivityManager.RunningServiceInfo service11:manager.getRunningServices(Integer.MAX_VALUE)) {
Log.v("xxxxxxxxx",BindService.class.getName()+"****"+service11.service.getClassName());
if (BindService.class.getName().equals( service11.service.getClassName())) {

isRunning = true;
