带有 FLAG_IMMUTABLE 的 Kotlin PendingIntent 不适用于 exoplayer

Question

当我在音乐应用程序中播放歌曲时，我正在使用待处理的意图来创建通知栏。它曾经完美地工作，但我必须将我的 targetSdk 更新到 31 并且我遇到一个错误，告诉我我需要在endingIntent 中使用一些标志：

Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

问题是我在声明待决意图时使用此标志：

 val pendingIntent = PendingIntent.getActivity(
        applicationContext,
    0,
        packageManager?.getLaunchIntentForPackage(packageName),
        PendingIntent.FLAG_IMMUTABLE
    )

所以我不明白为什么它说我需要在我已经使用该标志时使用它？我错过了什么吗？

正如 @ianhanniballake 所建议的，崩溃发生在 exoplayer 依赖项中，而不是在我的代码中......

所以我继续在https://github.com/google/ExoPlayer/blob/release-v2/RELEASENOTES.md上检查所有 exoplayer 更新，我发现他们在 2.14.2 上实现了 PendingIntent.FLAG_IMMUTABLE 有趣的事情，只是一次迭代高于我正在使用的那个。

所以我更新了对 exoplayer 的依赖关系，一切正常。
