I’m developing a software layer that I would like to reuse several time for building my Android applications. Basically I want that, once installed, the software layer any other apps can use it (like a system library).
I was wondering what is the best solution for doing this, when I found that recently Android supports library projects (http://developer.android.com/guide/developing/projects/projects-eclipse.html#SettingUpLibraryProject).
So I decided to create my software layer as a library project, making the code it contains re-usable by the other applications I want to realize.
My software layer depends on a set of external jar, which are correctly located in the lib folder of the library project.
The problem is that when I create a new project referencing the library project I’m not able to see the classes defined into the external jars of the library project: i.e. it seems that they are not part of the classpath.
So when referring to a library project is possible to re-use only the source code defined there? If my library project have some other libraries I have to import these libraries also in the other ones (I want to avoid this!)?
I’m also interested to know if there are other ways for doing this, but searching around I haven’t found other ways for realizing Android libraries/shared code.
Thanks.
Ok I finally figured out that for solving this is sufficient to add the jars to the host project build-path (no need to re-import them, you can just choose the path from the library project). However it is weird that they are not automatically exported in the host project classpath.
