>找不到com.google.android.exoplayer:exoplayer-core:r2.4.2

Question

我面临这个exoplayer找不到错误的视频android工作室应用程序后，我更新了我的项目依赖。

我不知道如何更新旧的外部播放器链接到https://mvnrepository.com/artifact/com.google.android.exoplayer/exoplayer

有谁能告诉我如何删除这个错误并更新到最新的exoplayer版本吗？

// Top-level build file where you can add configuration options common to all sub-projects/modules.

        google()
        mavenCentral()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

        google()
        mavenCentral()

    }

Answer 1

在将这些添加到build.gradle后工作：

implementation 'com.google.android.exoplayer:exoplayer-core:2.15.1'
implementation 'com.google.android.exoplayer:exoplayer-dash:2.15.1'
implementation 'com.google.android.exoplayer:exoplayer-ui:2.15.1'

和启用多个索引。

请查看此https://exoplayer.dev/hello-world.html

Answer 2

在Google的Maven Repo上找不到Exoplayer库版本2.4.2。将实现更改为以下内容

implementation 'com.google.android.exoplayer:exoplayer-core:2.15.1'
