在初学react-native时，执行命令react-native run-android会报如下错误：
react-native run-android
Starting JS server...Building and installing the app on the device (cd android && ./gradlew installDebug...
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':app'.
> failed to find Build Tools revision 23.0.1

BUILD FAILED
解决办法：android SDK版本不对应，本文23.0.1版本对不上，用Android SDK Manager一查看果然如此，安装了23.0.2和23.0.3，就是唯独没有安装23.0.1。所以我就把android/app/build.gradle文件中buildToolsVersion "23.0.1"改为"23.0.2"，然后就测试通过了。本人觉得，如果把23.0.1 SDK装上估计也可以的。
