Question

I am using a reciever class defined in the manifest like

    <receiver 
      android:name="com.escortme.basic.SMSReceiverActivity"
      android:enabled="true">
      <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
      </intent-filter>
    </receiver>

to listen on incoming texts, but the problem is how do I call a method which is the current activity that the phone is showing, from the onrecieve method in SMSReceiverActivity ?

So for example, if I am currently on pol_viewactivity on my phone, then i recieve a text, i know that the onrecieve method occured in the background from SMSReceiverActivity, but in the onreceive method, how do I call a method back from pol_viewactivity?

Answer 1

Then you should either

1) put your onReceive method in your pol_viewactivity; or,

2) provide a listener in SMSReceiverActivity and set by pol_viewactivity.

EDITED:

In response to how to create a listener.

In your SMSReceiverActivity, define an interface,

public interface ExampleListener {
    onMsgReceive(String msg);
}

declare the listener and a public method,

private ExampleListener listener;

public void setExampleListener(ExampleListener listener) {
    this.listener = listener;
}

In the onReceive method of the BroadcastReceiver,

if (listener != null) {
    listener.onMsgReceive("Your message to pass");
}

In your pol_viewactivity, find ways to set the listener similar to the way of calling setOnClickListener(). If you cannot retrieve the instance of the SMSReceiverActivity in order to set the listener, then make the listener static. I know this is not a beautiful way to do so, but in your case, if you can’t change the design, this way should help. (Perhaps you can isolate the BroadcastReceiver into a single class and do all the handling there.)
