[FIXED] error: cannot find symbol import com.firebase.ui.database.FirebaseRecyclerAdapter;

Issue

I have the right library and dependencies the build gradle(app) file. But I'm still etting this error.

According to some answers here, I have already tried all of them. I already checked if i have the right version, whether i have included the package correctly, whether the package name is same in google-service.json file, in manifest file, or in gradle file. I have already done all these.

// All google dependencies

implementation 'com.google.android.gms:play-services-maps:12.0.1'
implementation 'com.google.android.gms:play-services-location:12.0.1'
implementation 'com.google.android.gms:play-services-places:12.0.1'
implementation 'com.google.android.gms:play-services-auth:12.0.1'
implementation 'com.google.firebase:firebase-database:12.0.1'
implementation 'com.google.firebase:firebase-auth:12.0.1'
implementation 'com.google.firebase:firebase-messaging:12.0.1'
implementation 'com.firebaseui:firebase-ui:3.3.0'
implementation 'com.firebase:firebase-client-android:2.5.2'
implementation 'com.google.firebase:firebase-core:12.0.1'
implementation 'com.google.android.gms:play-services-gcm:12.0.1'
implementation 'com.google.android.gms:play-services:12.0.1'
implementation 'com.github.ar-android:DrawRouteMaps:1.0.0'

these are backdated on purpose.

as this answer(https://stackoverflow.com/a/39217164/11686135) suggests, i have already done that:

import com.firebase.ui.database.FirebaseRecyclerAdapter; import com.firebase.ui.database.FirebaseRecyclerOptions;

and this is the error its showing: Cannot resolve symbol 'database'

maybe somehow the dependencies not working...? i am really novice at this. thanks in advance

Solution

Perhaps you are missing a dependency, please refer to the

GitHub project for FirebaseUI,

you might be missing just one more dependency such as any of these:

dependencies {
// FirebaseUI for Firebase Realtime Database
implementation 'com.firebaseui:firebase-ui-database:5.0.0'

// FirebaseUI for Cloud Firestore
implementation 'com.firebaseui:firebase-ui-firestore:5.0.0'

// FirebaseUI for Firebase Auth
implementation 'com.firebaseui:firebase-ui-auth:5.0.0'

// FirebaseUI for Cloud Storage
implementation 'com.firebaseui:firebase-ui-storage:5.0.0'
