Question

Hi I'm learning to use Firebase from an Udacity Course. I got this error when I ran my app and have no clue about it. 11-23 16:48:34.995 3947-3947/com.google.firebase.udacity.friendlychat

Can anyone help me?

UPDATE build.gradle

apply plugin: 'com.android.application'

repositories {
    mavenLocal()
    maven { url 'https://maven.fabric.io/public' }
    flatDir {
        dirs 'libs'
    }
}

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.1"

    defaultConfig {

    // FirebaseUI Storage only
    compile 'com.firebaseui:firebase-ui-storage:1.0.0'

    // Single target that includes all FirebaseUI libraries above
    compile 'com.firebaseui:firebase-ui:1.0.0'

    // Firebase Auth

Answer 1

Matching the versions resolves this. In Compatibility with Firebase / Google Play Services Libraries, it matches

FirebaseUI Version   Firebase/Play Services Version

   1.0.0                   9.8.0

So if dependencies are changed to

compile 'com.google.firebase:firebase-database:9.8.0'
compile 'com.google.firebase:firebase-auth:9.8.0'
compile 'com.firebaseui:firebase-ui-auth:1.0.0'

instead of

compile 'com.google.firebase:firebase-database:10.0.0'
compile 'com.google.firebase:firebase-auth:10.0.0'
compile 'com.firebaseui:firebase-ui-auth:1.0.0'

which is the latest available firebase version for firebaseUI version, the app works fine

Answer 2

This is most likely do to a version incompatibility between Firebase, and FirebaseUI. I ran into the same issue, and spent 30-45 min trying to figure it out. Ultimately what I did in order to keep going with the "Firebase in a Weekend" tutorial was:

git checkout 1.04-firebase-auth-firebaseui-signin

This will switch to the branch at this point in the tutorial. It works fine after doing so.

Maybe not the ideal answer as to what the problem is, but will get you going again with the course.

Answer 3

You just need to add : compile 'com.google.android.gms:play-services-auth:x.x.x'(find the right version here). They missed to say that you also need to add play-services-auth dependency for google authentication to work.
