Android 12 Kotlin - 强烈考虑使用 FLAG_IMMUTABLE，仅当某些功能依赖于 PendingIntent 可变时才使用 FLAG_MUTABLE

Question

这是pendingIntent的代码:

val pi =
    PendingIntent.getActivity(
        applicationContext,
        0,
        ii,
        PendingIntent.FLAG_UPDATE_CURRENT
    )

使用它时出现此错误:

java.lang.IllegalArgumentException: de.xxx.xxx: 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.

我仍然需要更新 Activity ，所以如何添加 FLAG_IMMUTABLE或 FLAG_MUTABLE这是什么鬼，仍然能够更新 Activity ？基于 this我试过的答案:

val pi =
    PendingIntent.getActivity(
        applicationContext,
        0,
        ii,
        PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_IMMUTABLE
    )

但这会产生语法错误!
那么代码应该怎么看呢？

该问题和答案中目前显示的代码是Java。你正在用 Kotlin 写作。
在 Kotlin 中，使用 the or bitwise operator :

val pi =
    PendingIntent.getActivity(
        applicationContext,
        0,
        ii,
        PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE
    )
