运行脚本之后 一直提示这个状态 ：test_add_contacts (main.ContactsAndroidTests) ...

手动停止 appium 后，错误提示 log 如下：

eclipse 中报错如下：
WebDriverException: Message: u'A new session could not be created. (Original error: Could not find zipalign; do you have the Android SDK installed and the tools + platform-tools folders added to your PATH?)'

ps：sdk 已经安装，更新到最新了.
