Question

I’m writing a simple code launch a broadcast receiver when I receive a message. But I get a force close error. I’ve added the required permissions in the AndroidManifest.xml . I took the code for BroadcastReceiever from this site(http://www.androidcompetencycenter.com/2008/12/android-api-sms-handling/). Please show me where I’m going wrong. Here is my code:

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();
    }

Here is the logCat:

Answer 1

The class’ fullname is incorrect in the declaration of the receiver.

In your manifest file, you must replace

com.example.smsmanager1.receiver.SMSReceiver

by

com.example.findme.SMSReceiver
