How to get Android application id?

Question

In Android, how do I get the application\'s id programatically (or by some other method), and how can I communicate with other applications using that id?

Answer 1

If by application id, you're referring to package name, you can use the method Context::getPackageName (http://http://developer.android.com/reference/android/content/Context.html#getPackageName%28%29).

In case you wish to communicate with other application, there are multiple ways:

1. Start an activity of another application and send data in the "Extras" of the "Intent"
2. Send a broadcast with specific action/category and send data in the extras
3. If you just need to share structured data, use content provider
4. If the other application needs to continuously run in the background, use Server and "bind" yourself to the service.
