how to retrive Registration id and send message to

The sender ID is used in the registration process for c2dm.but there has no receive messages or any register id.

//Akashc2dmActivity.java file

public class Akashc2dmActivity extends Activity implements OnClickListener {
    Button Register,id;
    private static PowerManager.WakeLock mWakeLock;

                    .getSystemService(Context.POWER_SERVICE);
            mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
                    WAKELOCK_KEY);
        }
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Register = (Button) findViewById(R.id.button);
        Register.setOnClickListener(this);
    }

public void sendRequest(View ignored) {

C2DMBroadcastReceiver.java file

if (Constants.RECEIVED_REGISTRATION_ID_FROM_GOOGLE.equals(intent.getAction())) {
//here you can get registration id
    final String registrationId = intent
                    .getStringExtra("registration_id");
/*your code*/
}

and then call registerIdWithC2DMService(registrationId) method from RegistrationIDRegistrar class.

There has above code code working successfully.There has some change in C2DMBroadcastReceiver.java class for receive message and There has add MessageClass.java class for sending message to server

C2DMBroadcastReceiver.java file

public class C2DMBroadcastReceiver extends BroadcastReceiver {
    NotificationManager nm;
     @Override
    public final void onReceive(Context context, Intent intent) {
        if (Constants.RECEIVED_REGISTRATION_ID_FROM_GOOGLE.equals(intent.getAction())) {
            Log.d(Constants.TAG, "Received a registration ID from Google.");
            intent.setAction(Constants.REGISTRATION_INTENT);
            intent.setClassName(context, RegistrationIDReceiver.class.getName());
        } else if (Constants.RECEIVED_C2DM_MESSAGE_FROM_GOOGLE.equals(intent.getAction())) {
            Function_notification(context,intent);
            Log.d(Constants.TAG, "Received a C2DM message from Google.");
            intent.setAction(Constants.START_C2DM_SERVICE);
            intent.setClass(context, C2DMService.class);
        }
        context.startService(intent);
    }
    private void Function_notification(Context context,Intent intent ) {

        Bundle extras = intent.getExtras();
        Log.d("extras",""+extras);
        String message2 = (String)extras.get("collapse_key");
        Log.d("collapse_key","collapse_key=" + message2);
        String message1 = (String)extras.get("payload");
        Log.d("extras","payload=" + message1);
        String error = intent.getStringExtra("error");
        Log.d("extras","error=" + error);
    nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    CharSequence from = "Please Testing for Recive message";
    CharSequence message = message1;
    Intent notifyintent = new Intent(context,Akashc2dmActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0,notifyintent, 0);
