I am working on Android application where I am integrating Firebase Analytics and Google AdMobs. I am getting Multi Dex issue if I am using both together, independently both are working if I am not using other one Gradle link. I have used many solutions available on this platform, but nothing works for me.

I am putting my Gradle files along with the error which I am getting on compile time.

App Level Gradle:

buildscript {

    repositories {

        maven { url 'https://maven.fabric.io/public' }

    }

        classpath 'io.fabric.tools:gradle:1.+'

    }

}

apply plugin: 'com.android.application'

        jcenter()

        }

        jcenter()

    }

}



task clean(type: Delete) {

    delete rootProject.buildDir

}

Error which I am getting on Console:

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

> java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

Solution which I am currently using to fix this issue but still error is coming, I am using it in my Application Class:

MultiDex.install(this);

For me,

multiDex problem is always version conflict problem.
So in my opinion, don't need to install MultiDex and just try to keep same version of every gradles.

I have solved my problem thats why want to share for others. It was giving me a Dex file issue because for Analytics I was using Firebase and for Admobs I was using Google Libraries. Same features & functionality of Admobs is also available in firebase and integrated also. So now I am using now Firebase libraries only and it is now not giving any Dex issue:
