直接引用dms jar包或者aar包都无法打包so库和assets文件，
LOCAL_ASSET_DIR := $(LOCAL_PATH)/assets，这个会在jar里编译报错
因此实现为：
1.apk 引用 dms编译生成的jar包(SensetimeDMS)，SensetimeDMS只包含sdk中的src文件
2.SensetimeDMS jar不直接引用so库，apk使用jar相当于增加class类而已，引用放在app中，使用如下这种方式引用so
LOCAL_JNI_SHARED_LIBRARIES += libjni_dms_sdk
LOCAL_SHARED_LIBRARIES += libdms_sdk_c_api
3.assets文件，jar包无法使用到，需要把jar的assets文件，拷贝到app中使用LOCAL_ASSET_DIR来引用
LOCAL_ASSET_DIR := $(LOCAL_PATH)/assets
4.sdk里面的库打包到system/lib64里面去，apk引用后，会在lib里生成链接
Sample如下
