try {

                Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), Your-Image);
                File file = new File(PageView.this.getCacheDir(), String.valueOf(largeIcon
                        + ".png"));
                FileOutputStream fOut = new FileOutputStream(file);
                largeIcon.compress(Bitmap.CompressFormat.PNG, 100, fOut);
                fOut.flush();
                fOut.close();
                file.setReadable(true, false);
                final Intent intent = new Intent(     Intent.ACTION_SEND);
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
                intent.setType("image/png");
