android notification 重启app不重载

int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
Notification noti = new Notification(icon, contentTitle, when);
noti.flags |= flag;
 
PackageManager pm = context.getPackageManager();
Intent notificationIntent = pm.getLaunchIntentForPackage(context.getPackageName());
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.putExtra("notificationTag", tag);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
 
noti.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

上面的方法解决不了


   notificationIntent.setAction(Intent.ACTION_MAIN); 
                
notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER); 

这样就可以了
