Developing two android apps and communicating between two
android, communication
Solution
You cannot directly access methods of `Activity` in different app.
`Broadcast` would work but if you want more control (i.e. invoke remote methods) consider binding to a remote service in the other app or use `Messenger` and handler to communicate.
Here is a short tutorial on inter-app communication
Problem
I am developing two applications names A and B. Application A as activity named `MainActivity`, service called `UpdateService`, `BroadcastReciever` called `UpdateReceiver`. Application B as activity named `TestActivity`, service called `DoService`, `BroadcastReciever` called `DoReceiver`. In my application B, I want to access few methods and code from `MainActivity` which is in Application A. In this way, I need full control of Application A code to access it in my application B. How can I achieve it?
