没适配就会有如下报错

  1. java.lang.IllegalArgumentException: com.example.imdemo: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
  2. 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.

解决方法

  1. 将项目的targetSdkVersion由31改为30
  2. 如果不想改targetSdkVersion，那就在在创建PendingIntent的时候判断当前系统版本，根据不同系统版本创建带有不同flag的PendingIntent，具体代码实现如下： ```java PendingIntent pendingIntent; if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.S) { pendingIntent = PendingIntent.getActivity(this, 123, intent, PendingIntent.FLAG_IMMUTABLE); } else { pendingIntent = PendingIntent.getActivity(this, 123, intent, PendingIntent.FLAG_ONE_SHOT); }

```
