电话管理员。在targetSdkVersion设置为31或android 12后，监听不工作

Question

在我将targetSdkVersion升级到31 telephonyManager之后。听着，这不管用。考虑下面的代码行：

电话管理员。监听（phoneStateListener，phoneStateListener.listen\u CALL\u STATE）；

Logas错误信息如下：

我在Android Manifiest文件上添加了以下权限，但仍然不起作用。

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

在将目标锁定在31岁以下或Android12岁以下之前，它工作得非常好。如何在Android SDK 31上解决这个问题？提前谢谢。

我就是这么做的：

    private suspend fun updateServiceState() {
        withContext(Dispatchers.Main) {
            telephonyManager.listen(object : PhoneStateListener() {
                override fun onServiceStateChanged(state: ServiceState) {
                    telephonyManager.listen(this, LISTEN_NONE)
                    ...
                }
            }, PhoneStateListener.LISTEN_SERVICE_STATE)

        }
    }

我的目标是Android 12和API 31，我没有READ_PHONE_STATE许可
