我有一个应用程序崩溃，因为

2022-09-20 06:42:22.691 25636-25738/com.example.mqttkotlinsample E/AndroidRuntime: FATAL EXCEPTION: MQTT Rec: 
    Process: com.example.mqttkotlinsample, PID: 25636
    java.lang.IllegalArgumentException: com.example.mqttkotlinsample: 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.

当我点击所指示的行，即(PendingInvent.java：401)，我将在PendingInvent.java中显示以下内容

private static void checkFlags(int flags, String packageName) {
        final boolean flagImmutableSet = (flags & PendingIntent.FLAG_IMMUTABLE) != 0;
        final boolean flagMutableSet = (flags & PendingIntent.FLAG_MUTABLE) != 0;

        if (flagImmutableSet && flagMutableSet) {
            throw new IllegalArgumentException(
                "Cannot set both FLAG_IMMUTABLE and FLAG_MUTABLE for PendingIntent");
        }

        if (Compatibility.isChangeEnabled(PENDING_INTENT_EXPLICIT_MUTABILITY_REQUIRED)
                && !flagImmutableSet && !flagMutableSet) {
            String msg = packageName + ": Targeting S+ (version " + Build.VERSION_CODES.S
                    + " and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE"

我找到了以下代码来帮助停止崩溃，但我不知道把它放在哪里。

val updatedPendingIntent = PendingIntent.getActivity(
   applicationContext,
   NOTIFICATION_REQUEST_CODE,
   updatedIntent,
   PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT
)

我知道我在寻求他人帮助方面知识并不渊博，也不太乐于助人，但我对Android Studio非常陌生。我应该在我的主代码中寻找什么？兼容性？GetActivity。我只是需要一些指导。请。我需要发布我的一些代码吗？
