How to solve this Error ...???

Answer 1

Bump dependencies versions:
classpath 'com.android.tools.build:gradle:3.5.2'
classpath 'com.google.gms:google-services:4.3.3'
firebase_database: ^3.1.0
firebase_core: ^0.4.2+1
In app/build.gradle add these:
android {
...
defaultConfig {
...
multiDexEnabled true // add this
}
}
dependencies {
...
implementation 'com.android.support:multidex:1.0.3' // add this
}
Don't forget to create google-services.json file in app/ folder and fill it with your data (docs link) or use some mock (like this one):
{
"project_info": {...},
"client": [...],
}
