This is my mainActivity. I want to write data on realtime database using this code. I have already created database. I have url of my images. I am just unable to connect them with realtime database.

implementation platform('com.google.firebase:firebase-bom:29.0.3')
implementation 'com.google.firebase:firebase-analytics-ktx'
implementation 'com.google.firebase:firebase-database-ktx'

These are my dependencies.

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

These are my rules for realtime database. Please help me with this.

I created another similar project and it worked out for me. I don't know the problem in my project but now my new project is working fine.
