Broadcast Receiver Not Working After Device Reboot in Android

Question

I have already checked all the related questions and have not found any solution for this problem. So this is an absolutely new problem for me.

What I Have

Answer 1

I have been struggling with this issue from almost a year. In all my apps, I show a notice to users to disable battery optimization for my app.

After a lot of testing on One Plus devices, I am able to receive boot completed broadcast when battery optimization is turned off for my app. In my opinion, it is much better than the accessibility service discussed above.

The simplest way to ask the user to disable the battery optimization for your app is to show some kind of notice, and open the battery optimization page when the user clicks on it. You can use the below code to do that.

public void openPowerSettings(View v) {

    /* Make Sure to add below code to manifest
    
    */

    try {
        Intent i = new Intent(android.provider.Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS);
        startActivityForResult(i, 1);
    }  catch (Exception e) {
        Log.e (TAG, "Exception: " + e.toString());
    }

}

And you can also hide the notice if below function returns true.

public static boolean is_ignoring_battery_optimizations(Context context) {
    String PACKAGE_NAME = context.getPackageName();
    PowerManager pm = (PowerManager) context.getSystemService(context.POWER_SERVICE);
    boolean status = true;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        status = pm.isIgnoringBatteryOptimizations(PACKAGE_NAME);
    }
    return status;
}
