android library project and Activities

Question

I'm developing an Android SDK library. In this library I've declared and used some Activities. Now I've tried to include the library in an application but I've noticed that I must declare all the library activities in the app. This is a very bad thing because in the library, I've included a lot of activities and the developer has to copy all the activities in his own app. Is there a solutions to this?

Answer 1

No, this is a known limitation of the libraries at the moment. There is a lot of discussion in the android development community of fixing this in the future, but for now it is a limitation of how they do libraries.

From the doc

In the manifest file of the application project, you must add declarations of all components that the application will use that are imported from a library project. For example, you must declare any <activity>, <service>, <receiver>, <provider>, and so on, as well as <permission>, <uses-library>, and similar elements.
