I have an class as below:

public class FYPSmsReceiverBroadcast extends BroadcastReceiver

I need to unregister the receiver as I am getting a force close error AFTER I have existed the application when I receive an SMS message. (indicating something is still listening for the sms but not able to access a particular activity because the app has been closed; the error only seems to happen after 1 text received, a second text seems to produce no force close error)

There are a number of somewhat similar questions, but none that can assist the method I have employed. I have tried adding an onPause like below:

 public void onPause() {


        unregisterReceiver(FYPSmsReceiverBroadcast);
    }

But this results in the following error in eclipse: ‘FYPReceiverBroadcast cannot be resolved to a variable’

In the onReceive method of the class that extends Broadcast receiver I have a call to:
FYPSpeakerActivity.speakSMSfrom();

Which calls another class that uses text to speech – This line appears to be the one being called (despite the application being closed) on receipt of an SMS, and creates the force close error.

Can anyone advise?

    FYPReceiverBroadcast is a class. You need to pass an object, here is an example:

    FYPReceiverBroadcast myFYPReceiverBroadcast = new FYPReceiverBroadcast(...);

...

public void onPause() {
     unregisterReceiver(myFYPReceiverBroadcast);
}

    This is such a fundamental programming concept, I recommend you to read the following article to learn the difference:

    An object is a software bundle of related state and
    behavior. A class is a blueprint or prototype from which objects are
    created.
