How to add firebase crashlytics into android projects

Question

In my application, I want to use firebase Crashlytics and for this, I added below codes into my application.
I added this codes step by step from google document!
I added below codes but when sync application show me an error and not sync project.

Build.gradle (project) :

buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.1.0'
        classpath 'io.fabric.tools:gradle:1.26.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
        maven { url 'https://dl.bintray.com/tapsellorg/maven' }
        maven { url 'https://maven.google.com/' }
    }
}

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

Build.gradle (app) :

dependencies {
    implementation 'com.google.android.gms:play-services-base:16.0.1'
    implementation 'com.google.firebase:firebase-core:16.0.6'
    implementation 'com.crashlytics.sdk.android:crashlytics:2.9.7'
}
apply plugin: 'com.google.gms.google-services'
apply plugin: 'io.fabric'

but when added this line apply plugin: 'com.google.gms.google-services' , when click on sync show me below error :

The library com.google.android.gms:play-services-base is being requested by various other libraries at [[11.0.2,11.0.2]], but resolves to 16.0.1. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

How can I fix it?

Answer 1

build.gradle Module

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


// add the Firebase SDK for Google Analytics
// The app need this to init in Firebase console
implementation 'com.google.firebase:firebase-analytics:17.2.1'

 // Add the Firebase SDK for Crashlytics.
implementation 'com.google.firebase:firebase-crashlytics:17.0.0-beta01'

build.gradle Project

classpath 'com.google.firebase:firebase-crashlytics-gradle:2.0.0-beta01'

You do not need fabric.io anymore, it is deprecated and will be available until March 31, 2020. Take a look at this Project and Video

if after all Firebase doesn't recognize the app, record an exception using this recordException
