I'm currently using Unity for developing an application for Android and IOS and I'm able to use the function: Application.OpenURL("mailto:" + email_address + "?subject=Email&body=msg from Unity");
to send emails from within my application, and I know you can use a similar function to open up the mobile devices SMS system however I'm unsure on how to actually go about this.
If anyone can please advise how I can open up the native SMS system through "Application.OpenURL()" that'd be fantastic. I'm also open to using an alternative solution if anyone's aware.
