Duplicate class in classes.jar on build project after update of Android Studio

Question

I have recently update Android Studio to the latest version and since I have been facing problem with the libraries connecting to it.

The latest problem faced is the following:

Cause 1: java.util.concurrent.ExecutionException: java.lang.RuntimeException: Duplicate class     com.google.android.gms.internal.measurement.zzsr found in modules classes.jar (com.google.android.gms:play-services-measurement-base:16.3.0) and classes.jar (com.google.firebase:firebase-analytics-impl:16.2.1)

I have checked the following questions but no suggestion would work: Android Studio: Resolving Duplicate Classes

This could be a duplicate question of the following: 61 Duplicate classes in classes.jar, WHERE is classes.jar located?. But unfortunately it was not answered. I hope it would attract attention to the issue.

Looks like duplicate classes of com.google.android.gms.internal.measurement from your play services and firebase package is getting included in the generated classes.jar. Try `./gradlew app:dependencies` and see from which specific libraries this is getting included. — raxerz, Jun 13 '19 at 07:52

@MohammadSommakia Thank for your contribution, I just need to mention that it's a wrong practice to remove the source sets for it will disable the ability to loadLibrary from system and access the libraries in jni folder — coder, Jun 25 '19 at 10:18
I was experiencing the same problem and I know this is not a real solution to underlying problem but, I managed to compile by upgrading my inclusion of all `com.google.android.gms` libraries to version `17.0.0`. So for example: `com.google.android.gms:play-services-analytics:17.0.0` — Fernando Jascovich, Jul 19 '19 at 21:35

are you mean ``implementation``? – Yoel Jan 25 '21 at 11:58

**I was using in old version of libraries I just convert it to the following **

  implementation 'com.google.firebase:firebase-core:19.0.1'
  implementation 'com.google.firebase:firebase-analytics:19.0.1'

also make sure you add the following in your gradle.bulid

multiDexEnabled true

check this if not then also don't forget to add this code

    compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

In build.grandle type multiDexEnabled true in buildTypes:

buildTypes {
    release {
        minifyEnabled false
        multiDexEnabled true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

In my situation, the error was quite similar but different classes

Duplicate class com.google.android.gms.common.api.zzb found in modules classes.jar (com.google.android.gms:play-services-base:12.0.1) and classes.jar (com.google.android.gms:play-services-basement:17.0.0)

I stumbled on this react-native issues thread where I found a fix. I simply included

implementation ("com.google.android.gms:play-services-base:+") {
    force = true
}

the plus allows com.google.android.gms:play-services-base:+ to get upgraded and use the latest version, I think some other dependency relies solely on it because I previously didn't have any google SDK or firebase lib in my project.

First I like to mention that this works fine, but the attribute force = true is deprecated. Second, according to google developer's site . . . . "Don't use the combined play-services target. It brings in dozens of libraries, bloating your application. Instead, specify only the specific Google Play services APIs your app uses." There fore, the solution for this is that use the latest version specifically. implementation 'com.google.android.gms:play-services-base:17.4.0' . . . . https://developers.google.com/android/guides/setup — Yosidroid, Sep 30 '20 at 18:26

There tends to be class conflicts if versions of play-services-places, play-services-maps, and play-services-location don't match up. For example, your app/build.gradle file should look like this:

dependencies{
   implementation 'com.google.android.gms:play-services-places:16.0.0'    
   implementation 'com.google.android.gms:play-services-maps:16.0.0'
   implementation 'com.google.android.gms:play-services-location:16.0.0'   
}

for my case was different but maybe could help

implementation fileTree(dir: 'libs', include: ['*.jar','*.aar'])
implementation(name:'HERE-sdk', ext:'aar')

problem was i was implementing same class of.aar so i received duplicate class warnings

implementation fileTree(dir: 'libs', include: ['*.jar'])

Duplicate class in classes.jar on build project after update of Android Studio
