I have a android library project and reusable drawable resources in it. Lets say package name is: com.vijay.mylib; Then i have a main project
com.vijay.mylib;
You probably would need to add your own uri for library and use it to refer to drawable.
xmlns:vijay="http://schemas.android.com/apk/res/com.vijay.mylib"
Then you should be able to access drawable using
@vijay:drawable/myImage
