1common.jar contains resource configuration enums. It is used by various tools, but also 2by layoutlib.jar 3 4Layoutlib.jar is built from frameworks/base.git and therefore is versioned with the platform. 5 6IMPORTANT NOTE REGARDING CHANGES IN common.jar: 7 8- The API must stay compatible. This is because while layoutlib.jar compiles against it, 9 the client provides the implementation and must be able to load earlier versions of layoutlib.jar. 10 11- Updated version of common should be copied to the current in-dev branch of 12 prebuilt/common/common/common-prebuilt.jar 13 The PREBUILT file in the same folder must be updated as well to reflect how to rebuild this 14 prebuilt jar file.
