RK3288 + Android 7.1
Overview
Add SDK interface for third-mode applications to call, and provide full application developers in the form of JAR packages.
achieve
- Add JAVA code and write Android MK

LOCAL_MODULE := sdkapi
#LOCAL_DX_FLAGS := --core-library
include $(BUILD_JAVA_LIBRARY)
- Modify the source MK file and add the compiled module sdkapi
