Error:(27, 13) Failed to resolve: com.google.firebase:firebase-core:9.8.0

Question

I\'m trying to use Firebase in my app.

After adding three lines to Gradle, I get this error:

Error:(27, 13) Failed to resolve: com.google.fir

Answer 1

As described here, add this:

dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.0.0'
    }

In your project level gradle file and this one in the app level gradle file:

dependencies {
  compile 'com.google.firebase:firebase-core:9.8.0'
}
apply plugin: 'com.google.gms.google-services'

Answer 2

I guess, you need to update google repository. Try running SDK manager and check if there is any update.

Look at the comment in sample here

dependencies {
  // ...
  compile 'com.google.firebase:firebase-core:9.8.0'

  // Getting a "Could not find" error? Make sure you have
  // the latest Google Repository in the Android SDK manager
}

Getting a "Could not find" error? Make sure you have the latest Google Repository in the Android SDK manager

Go to SDK Manager -> Extras and check of updates.

Answer 3

Make sure the Google Repository and its related repostories has been updated to the latest version. Check by going to the SDK Manager -> Extras Section.
