  • I think it's a network issue, please resync it again – Basi Jan 07 '19 at 04:54
  • in Gradle-wrapper-properties file i changed Gradle version to 3.2.1 but i have error Sync Failed and Gradle DSL method not found: 'google()' Possible causes:
    • The project 'ContactsMapAndroid' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0). Upgrade plugin to version 3.2.1 and sync project
    • The project 'ContactsMapAndroid' may be using a version of Gradle that does not contain the method. Open Gradle wrapper file
    • The build file may be missing a Gradle plugin. Apply Gradle plugin
