in my app, i'm able to launch the standard SMS view with this code
Intent smsIntent = new Intent(Intent.ACTION_VIEW);
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address", contactNumber);
startActivity(smsIntent);
i have watsapp installed in app, if i force tap on number, it throws me an option, would you like to use watsapp or default sms app?.
Is there a way to implement like that?
