    		String numero = id_camarero.getText().toString();
    		idcamarero=Integer.parseInt(numero);
    		//Register the actions we want to receive via broadcast
    		//MyService.LocalBinder.
    	 boolean ret= bindService(new Intent(MainActivity.this, MyService.class), androidServiceConnection, BIND_AUTO_CREATE);   		
    		 IntentFilter filter = new IntentFilter(MyService.DATA_RECEIVED_INTENT);
   		     registerReceiver(androidListener, filter);
    	 if((numero.trim().equals(""))||(existe==false)){
    		 AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
    	 
    				// set title
    				alertDialogBuilder.setTitle("Fallo de id");
    	 
    				// set dialog message
    				alertDialogBuilder
    					//.setMessage("Click salir para finalizarprograma")
    					.setCancelable(false)
    					.setPositiveButton("Salir",new DialogInterface.OnClickListener() {
    						public void onClick(DialogInterface dialog,int id) {
    							// if this button is clicked, close
    							// current activity
    							MainActivity.this.finish();
    						}
    					  })
    					.setNegativeButton("Reintentar",new DialogInterface.OnClickListener() {
    						public void onClick(DialogInterface dialog,int id) {
    							// if this button is clicked, just close
    							// the dialog box and do nothing
    							dialog.cancel();
    						}
    					});
    	 
    					// create alert dialog
    					AlertDialog alertDialog = alertDialogBuilder.create();
    	 
    					// show it
    					alertDialog.show();
    				}
    	 
    	 else{
    	// Intent intent= new Intent(GestorRestauranteActivity.this,MenuMesas.class);
    	// intent.putExtra("id", numero);//enviamos el id de camarero a la actividad que invocamos
    	// startActivity(intent);
    	 finish();
    	 }
    	}
    	  
    ;}
