我通过添加以下内容更改了我的 ~/.profile 文件：
PATH="/user/share/android-sdk-linux/tools:$PATH"
然后我注销并再次登录，但路径没有添加到 $PATH 环境变量中。我正在检查终端：
echo $PATH
/usr/share/android-sdk-linux/tools:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/jdk1.7.0_17/bin
请指教

我什至尝试过：
PATH=$PATH:/usr/share/android-sdk-linux/tools
EXPORT PATH
这里也没有运气。
