Answer 1

Download /dl/android/maven2/com/android/tools/build/gradle-core/3.1.2/gradle-core-3.1.2.pom

This suggests that you are using an old version of Gradle. Try upgrading to 3.2.0.

Answer 2

Try open the android dir in Android Studio as a Android Project,then open the \app\build.gradle and click sync button.
