我尝试运行位于路径 E：\ JetSoftPro \ ReactStudy \ React-Native \ React-Native-TODO \ react-native-demo 上的react-native应用程序。 SDK位于路径 E：\ JetSoftPro \ Android \ sdk_as （文件android \ local.properties）：
sdk.dir=E:\JetSoftPro\Android\sdk_as
因此，此sdk路径 E：\ JetSoftPro \ ReactStudy \ React-Native \ React-TODO \ react-native-demo \ frontend \ android \ E：JetSoftProAndroidsdk_as ：
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':app'.
> The SDK directory 'E:\JetSoftPro\ReactStudy\React-Native\React-TODO\react-native-demo\frontend\android\E:JetSoftProAndroidsdk_as' does not exist.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info debug option to get more log output.
