Simple BroadcastReceiver won"t work

I try to develope a simple Broadcastreceiver.

Here's my code:

public class MyClass extends BroadcastReceiver {



    @Override

    public void onReceive(Context context, Intent intent) {

        // TODO Auto-generated method stub

        Bundle extras = intent.getExtras();

        if (extras != null) {

            String state = extras.getString(TelephonyManager.EXTRA_STATE);

            Log.w("DEBUG", state);

            if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {

                String phoneNumber = extras

                        .getString(TelephonyManager.EXTRA_INCOMING_NUMBER);

                Toast.makeText(context, phoneNumber, Toast.LENGTH_LONG).show();

                Log.w("DEBUG", phoneNumber);

            }

        }

    }

}

Manifest.xml:

<uses-sdk android:minSdkVersion="10" />



    <application

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name" >



        <receiver android:name=".MyClass">



            <intent-filter>

                <action android:name="android.intent.action.PHONE_STATE"></action>

            </intent-filter>

        </receiver>

    </application>

All i want to do is to 'toast' the Number i'm calling (or when i get called).

Isn't it working that way? Its the only code i use at the moment. Just one Broadcastreceiver running in the background and fired with a phone-event.

Thanks, prexx
