Use LOCAL_PREBUILT_JNI_LIBS to install prebuilt JNI libraries extracted from the prebuilt apk, or prebuilts as source, to the app specific lib path. LOCAL_PREBUILT_JNI_LIBS accepts 2 kinds of files: - Files like @path/to/libfoo.so (path inside the apk) are JNI libs extracted from the prebuilt apk. In this case, all embedded JNI libs inside the prebuilt apk are stripped. - Files like path/to/libfoo.so (path relative to LOCAL_PATH) are prebuilts in the source tree. Those prebuilt JNI libs are not defined as modules in the build system, so this works around possible module name conflict. Bug: 13170859 Change-Id: I91bb844cc11b3621a85733bc7e8910f168957ef0
