Question

I am building an Android app that works by providing information via SMS to users.Users send an SMS to a predetermined number hardcoded in the APP and in turn receive a response.

To achieve this, I am using a broadcast Receiver in my Android Manifest

<receiver android:name=".SMSReciever"> 
        <intent-filter android:priority="2"> 
            <action android:name=
                "android.provider.Telephony.SMS_RECEIVED" /> 
        </intent-filter> 
    </receiver>

If I create a new class SMSReciever, then when a response is received, I would to somehow send the information back to the activity which the user has open on the screen. Is it possible I can do this in my main activity dynamically so that the app can be made more interactive?

I have learnt about the Context.registerReciever method, but how do I mention the priority for the receiver? If the receiver does not have a higher priority, then the messaging app might stop the broadcast from reaching my app. Has anyone come across a solution for something like this?

I used the following code to achieve what I was looking for!

IntentFilter fp = new IntentFilter();
fp.addAction("android.provider.Telephony.SMS_RECEIVED");
fp.setPriority(18);

//--- when the sms is received ---
registerReceiver(new BroadcastReceiver(){
    @Override
    public void onReceive(Context arg0, Intent arg1) { 
        //Processing for received broadcast happens here              
    }
}, fp);
