How to send email and How to get the user conformation in Android

Hi,

     I am sending the email by using an intent. How can I get confirmation that the email has sent or there has been an error back into the activity it was called from??
    This is my sample code....

  send.setOnClickListener(new OnClickListener() {

                                                             //    @Override

 public void onClick(View v) {

                                                                         

 RelativeLayout lila1 = (RelativeLayout) findViewById(R.id.relativeLayout2);

 lila1.removeAllViews(); // if you want to empty it

 lila1.setVisibility(8);

                                                                                        

rl = (RelativeLayout)findViewById(R.id.Home_relativelayout);

 View v1 = rl.getRootView();

 //    setDrawingCacheEnabled(true);

 v1.setDrawingCacheEnabled(true);

  final Bitmap bm = v1.getDrawingCache();

  String path = Images.Media.insertImage(getContentResolver(), bm, "title", null);

                                                                                                  

  Uri bUri= Uri.parse(path);                            

 Intent sendIntent;

 sendIntent = new Intent(Intent.ACTION_SEND);

                                                                                          sendIntent.putExtra(android.content.Intent.EXTRA_EMAIL,"");

                                                                        sendIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Test");

                                                                                                sendIntent.putExtra(android.content.Intent.EXTRA_STREAM,bUri);

                                                                                 sendIntent.setType("image/png");

                                                                                                sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Hy Testing");

                                                                                startActivity(Intent.createChooser(sendIntent, "Send Mail"));

                                                                         

Toast.makeText(getApplicationContext(), "Image"+(pos+1),Toast.LENGTH_SHORT).show();

                                                                         

     }

  });

                                                             

 }
