wish helps you You can put it as a parameter to the contructor and store it on the AsyncTask object. Store it as a WeakReference and check it on the onPostExecute, much like the best practices displaying images from the official doc at http://developer.android.com/training/displaying-bitmaps/process-bitmap.html
code :
private class TaskMensaje extends AsyncTask<String, Void, Void> {
   private WeakReference vRef;
   ... / your other stuff here   

   public TaskMensaje (View v) {
       vRef = new WeakReference(v);

    protected String doInBackground(String... params) {
        MensajeriaGestionablePARSER parserMensGest = new MensajeriaGestionablePARSER(urlMensGest);
        gestionables = parserMensGest.parse();

        mess_gest = gestionables.get(0).p0;
        return null;

    protected onPostExecute(Void result) {
        if (vRef != null && bitmap != null) {
           final ImageView imageView = vRef.get();
           if (imageView != null) {
               // Do whatever you want with your ImageView

I think the issue was by ths following , There is a pretty good example right on the AsyncTask doc page.
Pass your GMailSender object in to an AsyncTask, and call GMailSender#sendMail during doInBackground.
code :
public void onClick(View v) {
    final GMailSender sender = new GMailSender("username@gmail.com", "password");
    new AsyncTask<Void, Void, Void>() {
        @Override public Void doInBackground(Void... arg) {
            try {   
                sender.sendMail("This is Subject",   
                    "This is Body",   
            } catch (Exception e) {   
                Log.e("SendMail", e.getMessage(), e);
