Run application in background when phone in Doze

Question

Application is running SDK 23 and above. I am running some tasks using Service after completing the task and scheduling the next task using AlaramManager (setExactAndAllowWhileIdle). This is working fine. If the phone is idle continuously for 2 or 3 days then its going to Doze mode. After Doze mode ,application loosing the network and wakelock also not working.

Is there way even if phone is Doze can we run the application with any network interposition issues.I tried to keep the application witelist but i needs device to be rooted.

adb shell dumpsys deviceidle whitelist +<Package Name>

Can anyone suggest me which best way to run application without interruption?

Actually there is no way of doing this without running a foreground service. Having listed in white list may not be appropriate for your application and even though it is, you ask user to give you permission which can be seen as something dangerous from the end user's point of view.

However, I have a trick about this. Listen android's broadcasts and when you catch that device will move into doze mode, start a foreground service. In most of the cases user won't be able to see your foreground notification image and won't know that you are running a service. Because device is in the doze mode meaning it is stable in somewhere user not watching. So you can do whatever is needed.

You also listen broadcasts sent when doze mode is finished. When that happens, stop your foreground service and work in a normal logic of yours with alarm managers.

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    if(intent.getAction().equals("android.os.action.DEVICE_IDLE_MODE_CHANGED")){
        if (pm.isDeviceIdleMode()) {
            startForegroundService();
            //stopAlarmManagerLogic();
        } else {
            stopForegroundService();
            //startAlarmManagerLogic();
            return;
        }
        return;
    }
}
