廣播接收器啟動錯誤

Question

我正在編寫一個簡單的代碼，當我收到一條消息時啟動一個廣播接收器。 但是我得到一個強制關閉錯誤。 我已經在 AndroidManifest.xml 中添加了所需的權限。 我從這個站點（http://www.androidcompetencycenter.com/2008/12/android-api-sms-handling/）獲取了 BroadcastReceiever 的代碼。 請告訴我我哪里出錯了。 這是我的代碼：

package com.example.findme;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;



public class SMSReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();

        Object messages[] = (Object[]) bundle.get("pdus");
        SmsMessage smsMessage[] = new SmsMessage[messages.length];
        for (int n = 0; n < messages.length; n++) {
            smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);*/
        Toast.makeText(context,"Reveived!",1).show();
        }

        // show first message
       Toast toast = Toast.makeText(context, "Received SMS: " + smsMessage[0].getMessageBody(), Toast.LENGTH_LONG);
        toast.show();
    }

這是 logCat：

接收方聲明中類的全名不正確。

在您的清單文件中，您必須替換

com.example.smsmanager1.receiver.SMSReceiver

經過

com.example.findme.SMSReceiver
