gradle文件找不到：The specified Gradle installation directory '/E:AndroidAndroidStudioAndroid Studiogradlegradle-2.10' does not exist.
解决方案：
In Android Studio -> File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle
In "Use Gradle from" you choose 'gradle-wrapper.properties' file. And in Gradle JDK you choose what you need.
