Android: Understanding Using One IntentService With Multiple Activities

I have a problem with intent not to be delivered to IntentService

under a specific activity flow: This is the scenario:

• Consider 3 actions: Home, B and C. C has 2 fragments CF1 and CF2.
• B, CF1, and CF2 use the same IntentService class, but with different actions.
• The IntentService is started using startService(Intent)
  
  . (getActivity (). startService (Intent) for fragments)
• In cases where the IntentService is started, I am pretty sure it will be stopped using stopService(intent)
  
  if it is started in the Activity / Fragment onStop()
  
  .
• If the activity stream is Home → C → CF1 → CF2, everything works.
• If the activity stream is Home → B → C → CF1 → CF2, then it is onHandleIntent
  
  never called after starting the service (Intent) from CF2. B and CF1 are processed. For debugging, I tried to wait for the IntentService in Activity B to finish and then go to CF1 -> CF2, still the same problem. CF1 never has any problem starting the same service. When I tried to create a new class IntentService
  
  for CF2 it worked.

I figured out that IntentService has a queue for intents. If the service starts for the first time, the onStartCommand is called (which we shouldn't handle for the IntentService). If the service is already running, onHandleIntent is called for each subsequent call to startService.

Obviously I am doing something wrong, but it is not clear how what. I tried looking into other stackoverflow questions but didn't help. The code I'm using is pretty simple:

AndroidManifest.xml

<service android:name=".service.ExampleIntentService" />

      

        
        
        
      

    

Activity B

@Override
public void onCreate(Bundle savedInstanceState)
{
       .......
       intent = new Intent(getApplicationContext(), ExampleIntentService.class);
       intent.setAction(StringConstants.ACTION_B);
       serviceRunning = true; //set to false in onReceiveResult 
       startService(intent);
}

@Override
public void onStop()
{
      if(serviceRunning && intent != null)
          stopService(intent)
}

      

        
        
        
      

    

Fragment CF1

@Override
public void onResume()
{
    super.onResume();

    intent = new Intent(getActivity(), ExampleIntentService.class);
    intent.setAction(StringConstants.ACTION_CF1);
    serviceRunning = true; //set to false in onReceiveResult 
    startService(intent);
}

@Override
public void onStop()
{
      if(serviceRunning && intent != null)
          stopService(intent)
}

      

        
        
        
      

    

The code is exactly the same for the snippet, CF2
