创建NativeActivity项目（Eclipse）

新建android项目，添加native支持

移除JAVA Build Path对src目录的引用，并从硬盘上删除该文件夹

Project Properties | Java | Build Path | Source

修改AndroidManifest.xml

android:theme = "@android:style/Theme.NoTitleBar.Fullscreen"
<activity
android:name = "android.app.NativeActivity"
...
<meta-data android:name="android.app.lib_name"
android:value="???"/>
</activity>

创建jni/main.cpp

#include <android/log.h>
#include <android_native_app_glue.h>

int32_t inputEventHandler(struct android_app* app,AInputEvent* event) {
//deal with input event
}
void cmdEventHandler(struct android_app* app,int32_t cmd) {
//deal with cmd
}
void android_main(android_app* pApplication) {
app_dummy();                                                    //一定要保留该语句

__android_log_print(ANDROID_LOG_INFO,"myTag","hello%d",123);

pApplication->onAppCmd = cmdEventHandler;
pApplication->onInputEvent = inputEventHandler;

int32_t result;
int32_t events;
android_poll_source * source;

while(true) {
result = ALooper_pollAll(-1,
NULL,
&events,
(void**)&source);
if(result >=0) {
if(source) {
source->process(mApplication, source);
}
if(pApplication->destroyRequested) {
return;
}
}
}
}

修改jni/Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)                              #模块开始，清理全局变量
LS_CPP=$(subst $(1)/,,$(wildcard $(1)/*.cpp))      #自定义函数LS_CPP
LOCAL_MODULE := ???                                 #模块名
LOCAL_SRC_FILES := $(call LS_CPP,$(LOCAL_PATH))       #源文件
LOCAL_LDLIBS := -landroid -llog                     #依赖的链接库（无需编译）
LOCAL_STATIC_LIBRARIES := android_native_app_glue   #依赖的模块（可能需要编译）
include $(BUILD_SHARED_LIBRARY)                        #模块结束，编译成动态链接库

$(call import-module,android/native_app_glue)      #编译android_native_app_glue模块
