问题


I am new to android application development. I am developing an android application using c2dm. Can anyone tell me of how to receive the registration id for the application from c2dm. Please tell me with a detailed example and explanation


回答1:


public class C2dmEx extends Activity
{


static TextView mytext = null;
Context context = null;
Intent intent = null;



@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mytext = (TextView) findViewById(R.id.mytext);  
    mytext.setText("app started");


    Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
    registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); 
    registrationIntent.putExtra("sender","your Mail Id");
    startService(registrationIntent);

    mytext.setText("Grabbing your device registration ID.....");

    Log.i("Recieve","1");

  }
}



public class C2DMReceiver extends  BroadcastReceiver
{

//private CustomerBean customer = null;
private RegisterManager reg = null;
private C2dmEx ex = null;
int UserId = 0;
private boolean auth = false;
private CustLogin cl = null;

public C2DMReceiver()
{

    cl = new CustLogin();
}

@Override
public void onReceive(Context context, Intent intent)
    {
        Log.i("Recieve","2");
        C2dmEx.mytext.setText("Intent Received!");
        if (intent.getAction().equals("com.google.android.c2dm.intent.REGISTRATION"))
        {
            handleRegistration(context, intent);
        } 
        else if (intent.getAction().equals("com.google.android.c2dm.intent.RECEIVE")) 
        {
            handleMessage(context, intent);
        }
     }

    private void handleRegistration(Context context, Intent intent)
    {

        String registration = intent.getStringExtra("registration_id"); 
        if (intent.getStringExtra("error") != null)
        {
           C2dmEx.mytext.setText("There was an error with your device registration!");
            // Registration failed, should try again later.
        } 
        else if (intent.getStringExtra("unregistered") != null)
        {
            // unregistration done, new messages from the authorized sender will be rejected
           C2dmEx.mytext.setText("You have been unregistered!");
        } 
        else if (registration != null) 
        {
           // Send the registration ID to the 3rd party site that is sending the messages.
           // This should be done in a separate thread.
           // When done, remember that all registration is done.

        //  UserId = customer.getId();
        //  Log.i("id",String.valueOf(UserId));

            String RegId = registration; 
            Log.i("reg",String.valueOf(RegId) );
            C2dmEx.mytext.setText("Your registration code is: " + RegId);





        }
    }

    private void handleMessage(Context context, Intent intent)
    {
        C2dmEx.mytext.setText("You have been alerted!");
    }


}

and your manifest
