下面是我的gradle依赖:

compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.google.android.gms:play-services-ads:9.0.0'
compile 'com.google.firebase:firebase-core:9.0.0'

// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

有人可以帮我解决这个问题吗？

代替

      compile 'com.google.firebase:firebase-core:9.0.0'

同时通过 SDK 管理器更新到最新的 google-play-services 和 google 存储库:
