AndroidGradle无法解决

在Android SDK中更新Google Repository.版本47适用于我.

来自firebase doc:

dependencies {
    // ...
    compile 'com.google.firebase:firebase-core:10.2.4'
    compile 'com.google.firebase:firebase-messaging:10.2.4'
    // Getting a "Could not find" error? Make sure you have
    // the latest Google Repository in the Android SDK manager
}
