主要开发调用流程如下：

首先：在src/main/ 目录下新建一个jni文件夹

src/main/jni

第二步：

在jni文件里面添加一个Android.mk文件以及第三方so库及其头文件

第三步：

编写Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := T613_I2C_DLL

LOCAL_SRC_FILES := Source/SharedLibs/$(TARGET_ARCH_ABI)/libT613_I2C_DLL.so

include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := SerialPort

LOCAL_SRC_FILES := Source/SharedLibs/$(TARGET_ARCH_ABI)/libSerialPort.so

include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_C_INCLUDES += $(LOCAL_PATH)/Source/include

LOCAL_MODULE := T613_FPC

LOCAL_SRC_FILES := JNI.cpp

LOCAL_SHARED_LIBRARIES := T613_I2C_DLL SerialPort

include $(BUILD_SHARED_LIBRARY)

第四步：

配置一下app目录下的build.gradle文件。
