            File f=new File("path to the file");
            Uri uri = Uri.fromFile(f);
            sendIntent.setComponent(new ComponentName("com.whatsapp","com.whatsapp.ContactPicker"));
            sendIntent.setType("image");
            sendIntent.putExtra(Intent.EXTRA_STREAM,uri);
            sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators("919xxxxxxxxx")+"@s.whatsapp.net");
            sendIntent.putExtra(Intent.EXTRA_TEXT,"sample text you want to send along with the image");
