I'm facing issues when using one of the new Firebase features which came out a few days ago. My application has used Firebase before, but now I want to add the storage feature. Therefore I added the dependency to my gradle file:
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.firebase:firebase-storage:9.0.0' }
apply plugin: 'com.google.gms.google-services'
if you go to this link "https://console.firebase.google.com/project/yourprojectname/overview" when already logged in, you will see a button saying "Add Firebase to your Android app". Click on it and a popup will show up. On step 2 it will give you a download link for the google-servies.json file. Follow the steps and you're done.
