i tried connecting android project with firebase which was generating error

Question

I tried to resolve it but the problem is that we are using google dialogflow in our app

So on adding firebase Firestore dependency it is having duplicate classes in both . I tried to remove duplicate classes and also searched for solution on stack Overflow but nothing worked.

Solution referred (unsuccessful) Resolve duplicate classes with firebase and dialog-flow

i tried removing jcenter from the build.gradel but it doesn't work because it was used in the android project

Answer 1

You didn't add the Firebase or Firestore dependencies to your project.

1. Open the Firebase console
2. Create a new project
3. Add an Android app to your Firebase project - there is a step for step tutorial on Firebase

Easy to understand tutorial by Firebase: https://firebase.google.com/docs/android/setup?hl=en

Answer 2

You need to add the firebase classpath in the build.gradle.

1. Open Your project
2. Chose tools from the status bar
3. Select firebase from the dialog
4. Now Connect to the firebase.
