Not allowed to start service Intent - Android Oreo

Question

I am currently using the startWakefulService function which is crashing in Oreo. I realise I either have to switch to startForegroundService() and use a foreground service,

Answer 1

Based on the documentation:

As of Android O, background check restrictions make this class no longer generally useful. (It is generally not safe to start a service from the receipt of a broadcast, because you don't have any guarantees that your app is in the foreground at this point and thus allowed to do so.) Instead, developers should use android.app.job.JobScheduler to schedule a job, and this does not require that the app hold a wake lock while doing so (the system will take care of holding a wake lock for the job).

Only alternative is to start a ForeGroundService or use JobScheduler/JobIntentService

You can start foreground service as follows:

@Override
public void onReceive(Context context, Intent intent) {

    // Explicitly specify that GCMIntentService will handle the intent.
    ComponentName comp = new ComponentName(context.getPackageName(), GCMIntentService.class.getName());
    // Start the service, keeping the device awake while it is launching.
    ContextCompat.startForegroundService(context,intent.setComponent(comp));
    ...
}

You also need to call startService() from your Service class and display notification. You can follow my answer on this SO for implementation details.
