Background execution not allowed receiving intent BOOT_COMPLETED

Question

I\'ve read about Android Oreo background execution limitations, and it clearly states that BOOT_COMPLETED broadcast is unaffected, but I can\'t get it to work o

Answer 1

The solution was a combination of two attempts I had already made.

First, I had to start a foreground service (even a dummy service would be good) with sticky notification:

public class StartDetectionAtBoot extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            Intent intent1 = new Intent(context.getApplicationContext(), DummyService.class);
            context.startForegroundService(intent1);
        }

        Intent intent0 = new Intent( context, ActivityRecognitionService.class );
        PendingIntent pendingIntent = PendingIntent.getService(context, 111, intent0, PendingIntent.FLAG_UPDATE_CURRENT);
        ActivityRecognitionClient activityRecognitionClient = ActivityRecognition.getClient(context);
        activityRecognitionClient.requestActivityUpdates(5000, pendingIntent);
    }
}

Of course inside the service you start there must be an onCreate method which creates a notification and calls startForeground.

Secondly, I had did a cache invalidation in Android Studio and I also wiped emulator instance. This part of the solution was necessary for me since the first part still didn't work.
