Android Studio开发之JNI 加载使用第三方库

Posted 2021-09-12 老樊Lu码

一、第一步

在src/main/目录下新建一个JNI文件夹

 二、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：

 

 三、编写Android.mk，源码如下：

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)

四、配置一下app目录下的build.gradle文件，如下图所示
