firebase setup on android

Question

I can't setup the updated version of firebase on android studio. I've created json file of the project on the site firebase and copied it into the project and after coping lines in gradle:

buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}
apply plugin: 'com.android.application'
android {
  // ...
}
dependencies {
  compile 'com.google.firebase:firebase-core:9.0.1'
}
// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

I get the following error:

failed to resolve: compile 'com.google.firebase:firebase-core:9.0.0'

How can I fix it?

Answer 1

Firebase is working based on Google Play Services. So please make sure you have the following sdk tools and they are updated to sync against the library versions of firebase that you are using.

SDK Tools installed for this project

Project level build.gradle file

    // Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Module Level build.gradle file

apply plugin: 'com.android.application'

android {
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE-FIREBASE.txt'
        exclude 'META-INF/NOTICE'
    }

    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.devdeeds.firebaseauth"
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.firebase:firebase-auth:9.2.0'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
}


apply plugin: 'com.google.gms.google-services'

I had the same problem. If you are using Android studio, you should then update google repository in SDK Manager.

Following is my build.grade(app)

apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    useLibrary 'org.apache.http.legacy'
    defaultConfig {
        applicationId "package name"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    compile 'com.google.firebase:firebase-core:9.0.0'
}
apply plugin: 'com.google.gms.google-services'

And this is my build.grade(project)

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
        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 {
        jcenter()
    }
}
