Creating exact alarms on all Android versions

suggest change

With more and more battery optimizations being put into the Android system over time, the methods of the AlarmManager have also significantly changed (to allow for more lenient timing). However, for some applications it is still required to be as exact as possible on all Android versions. The following helper uses the most accurate method available on all platforms to schedule a PendingIntent:

public static void setExactAndAllowWhileIdle(AlarmManager alarmManager, int type, long triggerAtMillis, PendingIntent operation) {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M){
        alarmManager.setExactAndAllowWhileIdle(type, triggerAtMillis, operation);
    } else if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
        alarmManager.setExact(type, triggerAtMillis, operation);
    } else {
        alarmManager.set(type, triggerAtMillis, operation);
    }
}
