When I use implementation 'com.google.firebase:firebase-inappmessaging-display:17.2.0'
in my app/build.gradle
, I get this error:
Duplicate class com.google.common.util.concurrent.ListenableFuture found in modules guava-20.0.jar (com.google.guava:guava:20.0) and listenablefuture-1.0.jar (com.google.guava:listenablefuture:1.0)
Go to the documentation to learn how to Fix dependency resolution errors.
What I also have in my app/build.gradle
is this:
implementation 'com.google.android.gms:play-services-base:16.1.0'
implementation 'com.google.android.gms:play-services-analytics:16.0.8'
implementation 'com.google.android.gms:play-services-awareness:16.0.0'
implementation 'com.google.android.gms:play-services-cast:16.2.0'
implementation 'com.google.android.gms:play-services-gcm:16.1.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-maps:16.1.0'
implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-iid:17.1.2'
implementation 'com.google.firebase:firebase-messaging:17.6.0'
implementation 'android.arch.work:work-runtime:1.0.1'
implementation 'com.android.support:multidex:1.0.3'
apply plugin: 'com.google.gms.google-services'
Maybe one of the libraries that I am using already includes support for the In-App Messaging dependency, and then it becomes redundant? Thank you.

Google knows about this error so they made a special package to fix the conflict.
Add this to your build.gradle
implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
I found the solution at How to solve Program type already present: com.google.common.util.concurrent.ListenableFuture?. user2297550 said:
I merely added
implementation 'com.google.guava:guava:27.0.1-android'
at the end of my app gradle file and the error went away.
That was the solution for me. Now I have this and my app compiles correctly:
implementation 'com.google.firebase:firebase-inappmessaging-display:17.2.0'
implementation 'com.google.guava:guava:27.0.1-android'
I just came across this when building my Flutter project. Not quite sure why it reared its ugly head, but here I am.
So, if any Flutter devs come across this, @Ray Li's answer worked for me. The build.gradle
file that you want to edit is the one in the android/app
folder (ie. NOT the one in the android
folder).
Just add the implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
to the dependencies section at the end of the file, as follows:
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
}
Add this line in build.gradle
implementation 'com.google.guava:guava:27.0.1-android'
I encountered the same problem. I added the line below
implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
This works but I encountered another issue- Cannot fit requested classes in a single dex file (# methods: 89411 > 65536)
To resolve this error make sure to enable multiDex as below
defaultConfig {
applicationId "com.techweezy.smartsync"
minSdkVersion 19
targetSdkVersion 29
versionCode 5
versionName "1.4"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true //added this line
}
Then finally add the below lines.
implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
implementation 'androidx.multidex:multidex:2.0.1'
