if(internet connected )

if(hour value is between 7 to 22)

then trigger notification like Wallpaper of the day
set the notificationVariable value to 1 ( so that it doesn't trigger on 2nd,3rd,4th time when internet is connected)

}
到
这个
public int setAlarm() {

cal.set(Calendar.HOUR_OF_DAY, 1);//this is the main change

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
