标签: android crash sms

我试图了解如何接收短信并在android中获取其内容。 无论我尝试哪个例子,包括许多来自堆栈交换,每次,我的应用程序在收到短信时崩溃。我无法找到我做错的事。需要帮助。

代码:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.util.Log;


public class MySMSReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Object[] pdus=(Object[])intent.getExtras().get("pdus");
        SmsMessage shortMessage=SmsMessage.createFromPdu((byte[]) pdus[0]);
        Log.d("SMSReceiver","SMS message sender: "+
           shortMessage.getOriginatingAddress());
        Log.d("SMSReceiver","SMS message text: "+
           shortMessage.getDisplayMessageBody());
    }

}

您的接收者班级MySMSReceiver很可能不在包com.example.smstestbed中。因此,将接收器类移动到子文件夹com\example\smstestbed\并添加...

package com.example.smstestbed;
import android.content.BroadcastReceiver;
...

public class MySMSReceiver extends BroadcastReceiver {
    ....

将包声明发送给您的接收器类。
