android c2dm編程實例

Question

我是新來android應用程序開發。我正在開發一個使用c2dm的android應用程序。任何人都可以告訴我如何從c2dm接收應用程序的註冊ID。請告訴我一個詳細的例子和說明

Answer 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!"); 
    } 


}
