输入 adb devices：
出现： bash: /usr/local/Android-SDK/platform-tools/adb: No such file or directory
解决方案：
Ubuntu16.04 安装下面包：
sudo apt-get install lib32ncurses5
sudo apt-get install lib32z1
出现：adb: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory
接着安装下面的两个包就可以了
sudo apt-get install libbz2-1.0:i386 lib32stdc++6
