      gmail_share.setOnClickListener(new OnClickListener()
            {
                @Override
                public void onClick(View v)
    {
                    intent = new Intent(Intent.ACTION_SEND);
                    intent.setType("text/html");
                    intent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(gmail1_text));
                    intent.putExtra(Intent.EXTRA_STREAM, shareImageUri);
                    intent.putExtra(Intent.EXTRA_SUBJECT, "subject_text");

                    try{
                        startActivity(intent);
                    } catch (android.content.ActivityNotFoundException ex) {
                        Utils.showToastMessage(getActivity(),"Gmail Application is not found,please             install and try again");
                    }
                }
            });




     class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {

        }


public  Bitmap getBitmapFromURL(String src){
