start a remote service and receive a result in Android

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 i

Answer 1

First add a class like this:

package com.test.context; //For example
public class MyContext extends Application
{
   //Here you define the attributes to share through the application
   // with setters and getters
}

and in the AndroidManifest.xml, add the path of the class, in the example is com.test.context so:

<application android:name="com.test.context.MyContext"
                 android:icon="@drawable/ic_launcher"
                 android:label="@string/app_name">

Then in your code you can do some like this:

MyContext ctx = (MyContext)getApplication();

And you will be able to share data in all the app, btw activities and services, i did it this way in a Tasker , and works fine.

Answer 2

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()'.
