Android studio导入OpenCV-android-sdk出现Error:(22, 0) Gradle DSL method not found: 'android()'

Android studio版本号1.4，

OpenCV-android-sdk版本号3.1.0

在将OpenCV-android-sdk导入到Android studio中时，出现的错误：

Error:(22, 0) Gradle DSL method not found:'android()'

Possible causes:

• Theproject 'My Application' may be using a version of Gradle that does not containthe method.

  Open Gradle wrapperfile

• The build file may be missing a Gradleplugin.

  ApplyGradle plugin
