PendingIntent

java.lang.IllegalArgumentException: cn.zherui.kuaigun.idea: 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.

Android 12为目标平台的App，在构建PendingIntent时，需要指定Flag为FLAG_IMMUTABLE(建议)或FLAG_MUTABLE二者之一
如果还是崩溃，缺少implementation 'androidx.work:work-runtime:2.7.1'

记录一下自己踩得坑，浪费我半天时间
