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

Question

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 1

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

Answer 2

Check for the package name in gradle scripts (module:app) and in ...app>src>main>java.

Rename the folder to the desired package name. Make sure that the package name is changed in all the java files also. After renaming, sync your project with gradle files.

If you are doing this after the first Gradle sync, then this trick may not work. You need to change them manually.

Answer 3

implementation "androidx.concurrent:concurrent-futures:1.1.0"

Reference: https://developer.android.com/jetpack/androidx/releases/concurrent

Answer 4

I solved it by updating

 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_1_8.toString()
    }

api "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" 
to 
api "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"

also update these to latest versions, if applicable

api 'androidx.core:core-ktx:1.3.2' 
api "org.jetbrains.kotlin:kotlin-stdlib:1.4.32"

Answer 5

In addition to the accepted answer. I didn't user Exoplayer in the application. After digging deeper I found that if you use Google's library for guava to fix conflicts like this:

implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'

This will also cause an issue. Removing this dependency solved the problem. BUT on the other hand, if you use some library, which causes the problem with listenablefeature in opposite adding this dependency solves the problem.
