This video is old. In the same place where you use the libraries, paste:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'
compile 'com.android.support:cardview-v7:24.2.1'
compile 'com.android.support:recyclerview-v7:24.2.1'
compile "com.google.firebase:firebase-database:9.4.0"// banco
compile 'com.google.firebase:firebase-auth:9.4.0' // autenticador
compile 'com.google.firebase:firebase-storage:9.4.0' //arquivos
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services' // esse

buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
classpath 'com.google.gms:google-services:3.0.0' // esse
}
}
Then just start using ...
