Android.mk 中添加动态库编译例程 编译可执行程序

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := ffmpeg
LOCAL_SRC_FILES :=libffmpeg.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog -ldl
LOCAL_MODULE := ffmpeg1
LOCAL_SRC_FILES := FirstJNI.c
LOCAL_SHARED_LIBRARIES := ffmpeg

include $(BUILD_SHARED_LIBRARY)

需要注意的地方是 java 端调用时需要先加载 添加的动态库，注意顺序

修改Android.mk  ndk-build也可以编译成可执行文件
include $(BUILD_EXECUTABLE)
在Android 控制台界面下运行需要导出so库路径
export = /data/:$LD_LIBRARY_PATH
