the first gradle code is as below i shall be glad for your response.the error in the run says cannot resolve all the dependencies. which include; auth,core,and database.

apply plugin: 'com.android.application'

    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.appsound.instagram.tinder"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

Answer 1

Read Dependency types.

• Set :gradle:3.0.1
• Add google()

Add Google's Maven repository in your top-level build.gradle file:

allprojects {
    repositories {
        google()
        jcenter()
    }
}

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
       classpath 'com.android.tools.build:gradle:3.0.1'
        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
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle
