How to build my library project(aar) with android source code?

Question

I have a custom android system image, I'd like to build my aar project(lib1.aar) into our android source code. My app app1, app2 will use this lib1.aar as their dependencies. I used below Android.mk file to make it, but I got 'R cannot be resolved to a variable' error since my code imported it like calling string from resource file.

LOCAL_PACKAGE_NAME := lib1
LOCAL_CERTIFICATE := platform
LOCAL_PROGUARD_ENABLED := disabled 
include $(BUILD_JAVA_LIBRARY)

My question is how to write Android.mk file to compile my lib1.aar as a system lib to let my app use?

Thanks in advance.

You can include your .aar libs with these lines:

LOCAL_STATIC_JAVA_AAR_LIBRARIES:= <aar alias> include $(BUILD_PACKAGE) include $(CLEAR_VARS) LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := <aar alias>:libs/<lib file>.aar include $(BUILD_MULTI_PREBUILT)

Please, be aware of your projects and lib's minSDKVersion.
