How to connect with Crashlytics with android app

I'm trying to connect with firebase crashltics and integrated as per document. But I'm not able to track issue in firebase and firebase continuously show is following error

There are few Dependencies that you should put in PROJECT & MODULE Gradle. you can find them in the Crashlytic's Doc as you sent the picture (View The Docs).

Project's Dependencies:

repositories {
...
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
classpath('com.google.firebase:perf-plugin:1.3.1') {
        exclude group: 'com.google.guava', module: 'guava-jdk5'
    }
}

Module's Dependencies:

apply plugin: 'io.fabric'
apply plugin: 'com.google.firebase.firebase-perf'

    dependencies {
        implementation 'com.google.firebase:firebase-perf:19.0.5'
        implementation 'com.google.firebase:firebase-analytics:17.2.2'
        implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'
    }

It's IMPORTANT to know, these dependencies may different in the future. So you can find all of the required in Crashlytic's Doc
