Android How to package as API <p>I am working on providing SDK support for another apps by opening my app UI elements into another app. Its like having Facebook SDK integrated with other apps where one when click on "Login with Facebook" facebook UI comes up. Other apps like Uber has its own SDK How can I achieve it? One option is to have .jar/.aar file packaged. Or Deep linking works well? Please also suggest some documentation which can help me. Thanks,</p>
