How to bind two Android Activities to one Service?

Question

I would like to ask for some example, where two different activities (button in first activity open second activity), are communicating with one service (AIDL, etc.) I\'ve tried

Answer 1

You can do it by using Messenger that provide IPC communication without using AIDL. This is how you can bind multiple activities to a service.

If you need your service to communicate with remote processes, then you can use a Messenger to provide the interface for your service. This technique allows you to perform interprocess communication (IPC) without the need to use AIDL.

Have a look at this link. When you see the code, you will find a switch case withing a Handler, this will cater to the multiple requests that you will send from you multiple activities/components. Thanks. I hope the answer will be of help to you.
