I followed the instructions at Firebase Analytics quick start, but even after 24 hours, no user session was registered at Firebase Console.
I know that my google-services.json is correct because Firebase Auth is working properly (both Google and Facebook users are visible on the dashboard).
My Gradle dependencies are:
dependencies {
compile 'com.android.support:appcompat-v7:24.0.0'
compile 'com.android.support:design:24.0.0'
compile 'com.facebook.android:facebook-android-sdk:4.14.1'
compile 'com.google.android.gms:play-services-auth:9.2.1'
compile 'com.google.android.gms:play-services-maps:9.2.1'
compile 'com.google.code.gson:gson:2.1'
compile 'com.google.firebase:firebase-auth:9.2.1'
compile 'com.google.firebase:firebase-core:9.2.1'
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
}
