I think it should work if you are adding the receiver at the Manifest level and not at the Activity level(Using code). — Shashank Kadne, Aug 12 '12 at 10:44

you should move the receiver outside from the activity like this:

 <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".MessageActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".Reply" >
    </activity>
<receiver android:name=".SmsReceiver" >
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
 </application>

Under Android 3.0 and later, your broadcast is not guaranteed to be received unless the user has opened your application. The application does not have to remain opened, just to have been started once. This is caused by a flag (FLAG_EXCLUDE_STOPPED_PACKAGES) which is now part of most system broadcasts, which says the broadcast should not start a stopped application.

This was already answered in How to make android launch an application on received specific sms to keep it short: it is possible with BroadcastReceiver.
