Ошибка при получении сообщения для c2dm

/ 21 марта 2012

Я попробовал код для c2dm, и я успешно получил регистрационный идентификатор, но я не получаю сообщение от c2dm, может кто-нибудь мне помочь.

Мой основной класс 

 public class RegisterActivity extends Activity {  
    EditText text; 
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.main);  
    }  

    public void register(View view) {  
        Log.e("Super", "Starting registration");  
        Toast.makeText(this, "Starting", Toast.LENGTH_LONG).show();  
        text = (EditText) findViewById(R.id.editText1);  
        C2DMessaging.register(this, text.getText().toString());  
    }  
}

Мой класс регистрации 

public class ResultActivity extends Activity {  
    TextView view;
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.result);  
        Bundle extras = getIntent().getExtras();  
        if (extras != null) {  
            String string = extras.getString("message");  
            view = (TextView) findViewById(R.id.c2dm);  
            view.setText(string);  
        }  
    }  
}

Мой класс приемника 

public class C2DMReceiver extends C2DMBaseReceiver {  
    public C2DMReceiver() {  
        // Email address currently not used by the C2DM Messaging framework  
        super("dummy@google.com");  
    }  

    public void onRegistered(Context context, String registrationId)  
            throws java.io.IOException {  
        Log.e("C2DM", "Registration ID received");  
        Log.e("C2DM", registrationId);  
        Intent intent = new Intent(context, ResultActivity.class);  
        intent.putExtra("message", "Registration ID received");  
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
        context.startActivity(intent);  
    };  
    protected void onMessage(Context context, Intent intent) {  
            Log.e("C2DM", "Neue Message.");  
        Intent resultIntent = new Intent(context, ResultActivity.class);  
        resultIntent.putExtra("message", "Message received");  
        resultIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
        context.startActivity(intent);  
    }  

    public void onError(Context context, String errorId) {  
        Log.e("C2DM", "Error occured!!!");  
        Log.e("C2DM", errorId);  
    }  

}

и вот мой файл манифеста

Попробуйте добавить пустой конструктор в класс RegisterActivity, он должен выглядеть следующим образом: 

public class RegisterActivity extends Activity {  
    EditText text; 
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.main);  
    }

public RegisterActivity()
{

}

...

Требуется запустить службу регистрации.
