Question

I am creating an app in which on clicking on button user can send email.
But I want the task of sending email should be done in Background.
Someone suggested me to use AsyncTask but I am totally unaware of this.
can anybody tell me how to do it ?
I have sendEmail function which takes two string parameters(username , password) and I don’t know how to pass that two string args to AsyncTask and to doInBackground method.
my sendEmail function is

    public void sendEmail(String ownerEmailid, String datapwd )
{
    try {

        GMailSender sender = new GMailSender( ownerEmailid, datapwd );
        sender.sendMail( "This is Subject",   
                         "Hey buddy listen to this station it is awesome",
                         ownerEmailid,   
                         email );
    } catch( Exception e ) {
        Log.e("SendMail", e.getMessage(), e);   
    } 
}

please suggest solution.

in onClick call

new SendEmail(0).execute();

/** Inner class for implementing progress bar before fetching data **/
    private class SendEmail extends AsyncTask<Void, Void, Integer> 
    {
//if you want to show progress you can show here

  //  private ProgressDialog Dialog = new ProgressDialog(yourActivityClass.this);
    @Override
    protected void onPreExecute()
    {
//           Dialog.setMessage("Doing something...");
   //     Dialog.show();
    }

    @Override
    protected Integer doInBackground(Void... params) 
    {
        //Task for sending mail

try {

        GMailSender sender = new GMailSender( ownerEmailid, datapwd );
        sender.sendMail( "This is Subject",   
                         "Hey buddy listen to this station it is awesome",
                         ownerEmailid,   
                         email );
    } catch( Exception e ) {
        Log.e("SendMail", e.getMessage(), e);   
    } 
        return 0;
    }

    @Override
    protected void onPostExecute(Integer result)
        {

        if(result==0)
        {
//do some thing
        }

// after completed finished the progressbar
 //       Dialog.dismiss();
    }
