If you want to run a piece of code in the background at
certain intervals, then AlarmManager is the class helps us to do this. It will wake
up the device on the given intervals and invokes the Receiver class where we
should write our code to run in the background. Below code snippet explains how
to implement AlarmManager.
Intent notificationIntent = new Intent(context, LoadData.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntentSyncDB;=
PendingIntent.getBroadcast(context, 0,
notificationIntent,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
int intervalTime = 1000 * 60 * 5 ;// 5min
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),
intervalTime, pendingIntentSyncDB);
In the above snippet, LoadData is a broadcast receiver
class which executes the background code. AlarmManager invokes the LoadData for every
5mins.
