This is kind Of The main error highlighted

Did you add dependency to your project?

After adding the dependency is there another thing needed for it to work.

Are you getting another error?

Still the same error

Hi @Yomade_Stephens

The Real-Time Database functionality introduces a new library dependency - Make sure to read the Client-side Setup section for more information.

Especially pay attention to " Gradle Setup" chapter:

And make sure you add dependency to your app/build.gradle file:

dependencies {
implementation group: ‘com.backendless’, name: ‘backendless’, version: ‘5.0.+’

// required for real-time database and real-time messaging  
implementation ('') {  
  // excluding org.json which is provided by Android  
  exclude group: 'org.json', module: 'json'
