Error:(28, 0) Could not find method implementation() for arguments [com.android.support:appcompat-v7:25.3.1] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.
Please install the Android Support Repository from the Android SDK Manager.
<a href="openAndroidSdkManager">Open Android SDK Manager</a>
把build.gradle中的dependencies中的
implementation改為compile即可
原因:3.0的依賴改變書寫方式,如從3.0改為2.+需要做此改動
