i'm upgrading app new firebase version. followed guide, included classpath 'com.google.gms:google-services:3.0.0' in dependencies of project build.gradle compile 'com.google.firebase:firebase-core:9.0.1' among others in dependencies of module build.gradle , apply plugin: 'com.google.gms.google-services' @ end of file.
i "cannot resolve symbol 'firebase'" in imports i.e. import com.google.firebase.database.databasereference;. not errors appear when building, seems working, visible in code editor of android studio.
the imports worked fine couple of days ago (except firebaseauth, under maintenance). did not change code since (except trying upgrade 9.0.2, lead same result). thing did update components of android sdk, can't remember which. android sdk google repository , google play services of newest version. rebuilding, cleaning , invalidate caches / restart had no effect.
any ideas how fix this?
you need add dependency in build.gradle(app)
compile 'com.firebase:firebase-client-android:2.5.0'
