先说下我电脑的软件环境配置：

adt-bundle-linux-x86_64-20131030

（adt-bundle-linux-x86_64-20131030/sdk/platforms下面的都是我从同时拷贝的，这个下载太繁琐了）

ndk是android-ndk-r9b

一、用ndk-build编译

1、进入例子的目录：

cd android-ndk-r9b/samples/hello-jni

2、跑以下命令生成build.xml

android list target //看一下

android update project -p . -s -t 3 //选择对应的target

3、$ANDROID_NDK/ndk-build

二、使用ant生成apk

ant debug

出现了如下问题：

解决办法：

命令行输入android：

$android

在弹出的界面将Android SDK Build-tools从19改为18.1.1。

重行ant debug即可
