Support to build static Java library with Android resource Bug: 5714516 The rationale behind this change: - the library is compiled into a jar file, but its R class is generated making the constant not constant (static, not final static) (aapt option --non-constant-id). Also the jar file does not contain the R class. - this allows the integer value to not be inlined in the compiled class files. Note that this prevents using switch statements. - the main project use this jar file as a normal static library: it will add all the class files except the R.class. - the main project uses the library res folder as a resource folder with lower priority than the main project (basically the main project is an overlay. This is accomplished using aapt's --auto-add-overlay to handle resources only in the main project (which the normal overlay mechanism doesn't allow). - the main project creates R classes in the main project's package but also in the library's package. This is done with aapt's --extra-packages which accept as many packages as needed, separated by a :. - manifest merging is not done yet, so activities/services/permissions/etc... have to be manually declared in the main app. To use a static library with Android resource in your app, 1. Add the library's resource dir to your app as an overlay: LOCAL_RESOURCE_DIR := <app_resource_dir> <static_library_resource_dirs> 2. Set the proper aapt flags: LOCAL_AAPT_FLAGS := <apps_own_flags> --auto-add-overlay \ --extra-packages <lib1_package_name>:<lib2_package_name>:... Change-Id: Ifb4d2300b952ea4aaee74da1bb0c6c72ea0698a3
