Question

I know this has been asked ALOT on here, but I have been scouring the interwebs for hours and I have even reused some of my previous code for receiving sms’ and I got…nothing.

So, here goes, basic app to receive SMS but the app never receives the intent. I thought the intent may be ignored if the text is sent from the same phone but that does not seem to be the case, as other apps pick up the text fine.

Here is my manifest:

   <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.encima.smsreceiver"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".MainActivity" android:label="@string/app_name">
                        <intent-filter>
                                <action android:name="android.intent.action.MAIN" />
                                <category android:name="android.intent.category.LAUNCHER" />
                        </intent-filter>
         </activity>
         <receiver android:name=".MessageReceiver">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
            </intent-filter>
        </receiver>
    </application>
    <uses-sdk android:minSdkVersion="8" />
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
</manifest>

And, here is the receiver, nothing seems to be new here, so I have no idea what the problem is:

package com.encima.smsreceiver;

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

public class MessageReceiver extends BroadcastReceiver {

    private static final String TAG = "Message recieved";
    @Override
    public void onReceive(Context context, Intent intent) {
         Bundle pudsBundle = intent.getExtras();
         Object[] pdus = (Object[]) pudsBundle.get("pdus");
         SmsMessage messages =SmsMessage.createFromPdu((byte[]) pdus[0]);    
         Log.i(TAG,  messages.getMessageBody());
         Toast.makeText(context, "SMS Received : "+messages.getMessageBody(),
         Toast.LENGTH_LONG).show();
    }

}

The debug phone I am using is running 2.2.2 and I have other apps running that detect sms, including some of my own.

Any insight into this would be appreciated!

Thanks

Answer 1

Because the SMS broadcast intent is sent by
Context.sendOrderedBroadcast(…),
if any other app registers the BroadcastReceiver and calls abortBroadcast, the other receiver will not get the broadcast.

To increase the probability of your app receiving the broadcast create an IntentFilter, use IntentFilter.setPriority.
