start broadcast receiver android

Question

Estoy tratando de enviar mensajes de correo electrónico y SMS juntos. No hay problemas con el envío de correo, pero cuando envío sms recibo esta excepción:

End has leaked IntentReceiver
Are you missing a call to unregisterReceiver()? 

Aquí está mi código para el método de sms:

public class End extends Activity {

    Button btnSendSMS;
    EditText txtPhoneNo;
    EditText txtMessage;
    public EditText Details;
    public String user;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.end);
        Details = (EditText)findViewById(R.id.details);
        btnSendSMS = (Button) findViewById(R.id.btnSend);
        Bundle b=this.getIntent().getExtras();
        final String email=b.getString("keym");
        final String pno=b.getString("keys");

        btnSendSMS.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {           
                String detail=Details.getText().toString();
                Mail m = new Mail("[email protected]", "sdfsa"); 
                String[] toArr = {email}; 
                m.setTo(toArr); 
                m.setFrom("[email protected]"); 
                m.setSubject("EMERGENCY");
                m.setBody(detail);

                try { 
                    // m.addAttachment("/sdcard/filelocation"); 
                    if(m.send()) { 
                    Toast.makeText(End.this, "Email was sent successfully.", Toast.LENGTH_LONG).show(); 
                    } else { 
                  Toast.makeText(End.this, "Email was not sent.", Toast.LENGTH_LONG).show(); 
                    } 
                } catch(Exception e) { 
                //Toast.makeText(MailApp.this, "There was a problem sending the email.", Toast.LENGTH_LONG).show(); 
                Log.e("MailApp", "Could not send email", e); 
                } 

                sendSMS(pno, detail);
                finish();
                Intent intent = new Intent(End.this,Service.class);
                startActivity(intent);
               }   
            }
        );        

    } 

    private void sendSMS(String phoneNumber, String message)
    {        
         String SENT = "SMS_SENT";
         String DELIVERED = "SMS_DELIVERED";

         PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
             new Intent(SENT), 0);

         PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
             new Intent(DELIVERED), 0);

         //---when the SMS has been sent---
         registerReceiver(new BroadcastReceiver()
         {
             Context context;
             @Override
             public void onReceive(Context arg0, Intent arg1) {
                 switch (getResultCode())
                 {
                     case Activity.RESULT_OK:
                         Toast.makeText(getBaseContext(), "SMS sent", 
                                 Toast.LENGTH_SHORT).show();
                         break;
                     case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                         Toast.makeText(getBaseContext(), "Generic failure", 
                                 Toast.LENGTH_SHORT).show();
                         break;
                     case SmsManager.RESULT_ERROR_NO_SERVICE:
                         Toast.makeText(getBaseContext(), "No service", 
                                 Toast.LENGTH_SHORT).show();
                         break;
                     case SmsManager.RESULT_ERROR_NULL_PDU:
                         Toast.makeText(getBaseContext(), "Null PDU", 
                                 Toast.LENGTH_SHORT).show();
                         break;
                     case SmsManager.RESULT_ERROR_RADIO_OFF:
                         Toast.makeText(getBaseContext(), "Radio off", 
                                 Toast.LENGTH_SHORT).show();
                         break;
                 }


             }
         }, new IntentFilter(SENT));

         //---when the SMS has been delivered---
         registerReceiver(new BroadcastReceiver(){
             Context context;
             @Override

             public void onReceive(Context arg0, Intent arg1) 
             {

                 {
                     case Activity.RESULT_OK:
                         Toast.makeText(getBaseContext(), "SMS delivered",

                         Toast.makeText(getBaseContext(), "SMS not delivered",

                         break;                        
                 }

             }
         }, new IntentFilter(DELIVERED));        

         SmsManager sms = SmsManager.getDefault();
         sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);

Answer 1

Crea un receptor personalizado como este

class deliverReceiver extends BroadcastReceiver {     
@Override
 public void onReceive(Context context, Intent arg1) {
             switch (getResultCode())
             {
                 case Activity.RESULT_OK:
                     Toast.makeText(getBaseContext(), "SMS delivered", 
                             Toast.LENGTH_SHORT).show();
                     break;
                 case Activity.RESULT_CANCELED:
                     Toast.makeText(getBaseContext(), "SMS not delivered", 
                             Toast.LENGTH_SHORT).show();
                     break;                        
             }

         }
}

y un receptor enviado como este ..

class sentReceiver extends BroadcastReceiver {     
@Override
 public void onReceive(Context context, Intent arg1) {
             switch (getResultCode())
             {
                 case Activity.RESULT_OK:
                     Toast.makeText(getBaseContext(), "SMS sent", 
                             Toast.LENGTH_SHORT).show();
                     break;
                 case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                     Toast.makeText(getBaseContext(), "Generic failure", 
                             Toast.LENGTH_SHORT).show();
                     break;
                 case SmsManager.RESULT_ERROR_NO_SERVICE:
                     Toast.makeText(getBaseContext(), "No service", 
                             Toast.LENGTH_SHORT).show();
                     break;
                 case SmsManager.RESULT_ERROR_NULL_PDU:
                     Toast.makeText(getBaseContext(), "Null PDU", 
                             Toast.LENGTH_SHORT).show();
                     break;
                 case SmsManager.RESULT_ERROR_RADIO_OFF:
                     Toast.makeText(getBaseContext(), "Radio off", 
                             Toast.LENGTH_SHORT).show();
                     break;
             }


         }

ahora en el método sendSMS después de esto

 PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
         new Intent(DELIVERED), 0);

poner

registerReceiver(sentReceiver,SENT);
registerReceiver(deliverReceiver,DELIVERED);

Ahora anule onpause y anule el registro para los receptores como este ..

unregisterReceiver(sentReceiver);
unregisterReceiver(deliverReceiver);

Answer 2

Debe anular el registro de los receptores en onPause() y registrarlos en onResume() . De esta forma, cuando Android destruya y vuelva a crear la actividad para el cambio de configuración, o por alguna razón, todavía tendrá receptores configurados.

Answer 3

Ha registrado dos receptores de difusión en su actividad. En onDestroy de su actividad, anule el registro de ambos receptores. Consulte http://developer.android.com/reference/android/content/ContextWrapper.html#unregisterReceiver(android.content.BroadcastReceiver ).
