Android-is Library class Libraries reference places to note

In Android development, we may have an Android project-properties-android the following "is library", indicating that the project as a class library for other Android projects to reference.

For example, suppose you have a class library project A, you need to refer to A's other Android project B. So in the process of use, you need to pay attention to two points:

①, if you need to use the activity in A in B (which may be the case), you must declare the activity in a in the B's manifest file;

②, if A and B have a layout file of the same name, then B ignores the resource corresponding to the layout file in class library A, so the two cannot have duplicate names.

Note that the above two points can solve most of the problems that arise when referencing a class library.
