Android Studio class file for com.google.common.util.concurrent.ListenableFuture not found

I cannot build my project due to it failing because it cannot find a class. Is there something wrong with my sdk or dependancies?

I have tried invalidating cache and restarting. I am using api 29.

The following is where the error shows up

public class PodcastUpdateWorker extends Worker {

}

Here is the error printout

/home/snowman/AndroidStudioProjects/CorbettReportPodcasts/app/src/main/java/com/example/corbettreportpodcasts/PodcastUpdateWorker.java:36: error: cannot access ListenableFuture
public class PodcastUpdateWorker extends Worker {
       ^
  class file for com.google.common.util.concurrent.ListenableFuture not found

and my dependancies

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.1'

    implementation 'androidx.work:work-runtime:2.4.0'
    implementation 'com.google.android.material:material:1.2.1'
}

any help is appreciated

Answer

There is an issue with the exoplayer library conflicting with listenablefuture causing it not to be found. READ MORE

you can include guava implementation 'com.google.guava:guava:29.0-android' to fix this
