Question

Android: i want to create service by extending a Service class which i start when application get started and all activities can share its state and when i want stop it from other activity and when i want start it again from any activity ?

Answer 1

You can write your own MyApplication class extending Application class, put it in AndroidManifest.xml as

<application ... android:name=".MyApplication"> ... </application>

and start your service and bind to it in MyApplication.onCreate() method.

You can access the binder from any Activity class:

Application app = getApplication();
MyApplication myApp = (MyApplication) app;
myApp.getServiceBinder() // need to implement this method first
