Android Kotlin:当设备接收到新的文本消息时，监听事件不起作用

class SmsReceiver : BroadcastReceiver() {
    override fun onReceive(context: Context, intent: Intent) {
        if (intent.action == "android.provider.Telephony.SMS_RECEIVED") {
            // 处理接收到的短信
            val smsMessages = Telephony.Sms.Intents.getMessagesFromIntent(intent)
            for (smsMessage in smsMessages) {
                val messageBody = smsMessage.messageBody
                val sender = smsMessage.displayOriginatingAddress
                Log.d("SmsReceiver", "Message from: $sender, Body: $messageBody")
            }
        }
    }
}

<receiver android:name=".SmsReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

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

val smsReceiver = SmsReceiver()
val intentFilter = IntentFilter("android.provider.Telephony.SMS_RECEIVED")
registerReceiver(smsReceiver, intentFilter)

// 在不需要时注销
unregisterReceiver(smsReceiver)
