ubuntu-sdk-ndk-envconfig
根据放置SDK与NDK文件夹的位置，将目录粘贴到如下的位置，置放到.bashrc文件中，之后执行：
source ～/.bashrc
export ANDROID_HOME=/home/sui/android/android-sdk
export PATH=$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$PATH
export NDK_HOME=/home/sui/android/android-ndk
export PATH=$NDK_HOME:$PATH
环境配置是否正确，可以在终端中检验，以此输入“android”可以出现Android SDK Manager
输入“ndk-build”可以看到如下：
Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.
/home/sui/android/android-ndk/build/core/build-local.mk:143: *** Android NDK: Aborting . Stop.
说明配置正确，进入NDK的存放目录下进入samples文件夹下，可以进入hello-jni目录下面，输入“ndk-build”，出现如下：
