Kotlin PendingIntent with FLAG_IMMUTABLE 不适用于 exoplayer

Question

当我在我的音乐应用程序中播放歌曲时，我正在使用一个挂起的意图来制作通知栏。它曾经工作得很好，但我必须将我的targetSdk更新为31，我遇到一个错误，告诉我我需要使用一些标志与我的pendingIntent:

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，当我声明我的挂起意图时，我使用这个标志:

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使用的标志，当我已经使用它?我错过什么了吗?

根据@ianhanniballake的建议，崩溃发生在exoplayer依赖项中，而不是在我的代码中…

所以我去https://github.com/google/ExoPlayer/blob/release-v2/RELEASENOTES.md检查所有exoplayer更新，我发现他们在哪里实现了PendingIntent。FLAG_IMMUTABLE是一个有趣的东西，它在2.14.2中只比我使用的迭代高一次。

所以我更新了对exoplayer的依赖，一切都工作了。
