使用android studio设置Firebase进行身份验证

Question

I am trying to setup my android project with Firebase so that I can allow users to login and sign up for my app. I have connected my app to Firebase but when I try and add Firebase Authentication to my app I get the following error:

The library com.google.android.gms:play-services-base is being requested by various other libraries at [[15.0.1,15.0.1]], but resolves to 16.0.1. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

Answer 1

Try updating both all the Play Services and Firebase libraries to the latest version. For more information take a look at https://developers.google.com/android/guides/releases#may_23_2018

Hopefully this helps!
