Question

I have two applications.
One app has the Activity and another one is a background service.

I can able to access the service app from my activity app using implicit intent filters.

I need to receive a result from the service.

For ex:

From activity app, i am going to start the service and send a data.
In the service app, i need to receive the data and do some inspections and need to return to the activity app as modified result.

I can able to send by putExtra and can able to retrieve it in the service by getExtra. I need to return a value from service and receive it in activity app.

PS: The thing i needed is, the same way what we do with finish() and onActivityResult() with the Activity results.

Thanks in advance to you masters…

Answer 1

Why do you want to communicate through intent while there is a perfectly working binder protocol.

If an activity starts a service with ‘bindService()’ then the service will run until the activity calls ‘unbindService()’.
