This is called "multiple inheritance", and Java - the language - doesn't have this feature, regardless of the platform (Android or not).

Break up your code logic into more fine-grained pieces. You can bind to the service from multiple activities, as many as necessary.

Also, you don't need to explicitly create Service objects - this is done for you by the Android framework, when you either bind to a service, or just start it.

Hi,
I had a basic question.
Can my class extend 2 or more classes at a time. What is the syntax.
I want to extend Activity as well as Application. Wont this create
problems in the manifest file?
Activity because, I need to do a couple of things during the
onCreate() [binding a service]and Application, because I am creating
objects of another class [service class]which needs to be accessible
throughout my application.


Thanks,
Priyank
