Apparently, my problem was solved after installing SDK Platform for Android 6.0 or API 23. API 24 or higher ie Android 7.0 (Nougat) didnt run. 显然，安装适用于Android 6.0或API 23的SDK平台后，我的问题得以解决。未运行API 24或更高版本（即Android 7.0（牛轧糖））。 If still not solved then install SDK Platform for even lower APIs like 22,21 ... Hope it helps. 如果仍未解决，请为更低的API（例如22,21）安装SDK平台……希望对您有所帮助。
