Android 8.0: java.lang.IllegalStateException: Not allowed to start service Intent

Question

On application launch, app starts the service that should to do some network task. After targeting API level 26, my application fails to start service on Android 8.0 on back

Answer 1

If any intent was previously working fine when the app is in the background, it won't be the case any more from Android 8 and above. Only referring to intent which has to do some processing when app is in the background.

The below steps have to be followed:

1. Above mentioned intent should be using JobIntentService instead of IntentService.

2. The class which extends JobIntentService should implement the - onHandleWork(@NonNull Intent intent) method and should have below the method, which will invoke the onHandleWork method:

   public static void enqueueWork(Context context, Intent work) {
       enqueueWork(context, xyz.class, 123, work);
   }
   

3. Call enqueueWork(Context, intent) from the class where your intent is defined.

   Sample code:

   Public class A {
   ...
   ...
       Intent intent = new Intent(Context, B.class);
       //startService(intent); 
       B.enqueueWork(Context, intent);
   }
   

The below class was previously extending the Service class

Public Class B extends JobIntentService{
...

    public static void enqueueWork(Context context, Intent work) {
        enqueueWork(context, B.class, JobId, work);
    }

    protected void onHandleWork(@NonNull Intent intent) {
        ...
        ...
    }
}

4. com.android.support:support-compat is needed for JobIntentService - I use 26.1.0 V.

5. Most important is to ensure the Firebase libraries version is on at least 10.2.1, I had issues with 10.2.0 - if you have any!

6. Your manifest should have the below permission for the Service class:

   service android:name=".B"
   android:exported="false"
   android:permission="android.permission.BIND_JOB_SERVICE"
   

Hope this helps.
