找不到 com.google.common.util.concurrent.ListenableFuture 的 Android Studio 类文件

Question

我无法构建我的项目，因为它失败了，因为它找不到类。我的 SDK 或依赖项有问题吗？

我试过使缓存无效并重新启动。我正在使用 api 29。

以下是错误出现的地方

public class PodcastUpdateWorker extends Worker {

}

这是错误打印输出

/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

和我的依赖

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

任何帮助表示赞赏

Answer 1

exoplayer 库存在与 listenablefuture 冲突的问题，导致无法找到它。阅读更多

你可以包括番石榴implementation 'com.google.guava:guava:29.0-android'来解决这个问题

Answer 2
