3. Integrating into your application
Add the following gradle dependencies to your general gradle file
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
// more stuff
dependencies {
// classpath com.android.tools.build:gradle entry as before
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
// more stuffAdd the following gradle dependencies to your app gradle file
dependencies {
// ... more stuff
compile 'com.google.firebase:firebase-database:10.2.1'
