Using the native sms app to send an sms without launching itself
I have noticed many apps have the ability to send a text message to any phone, usually with codes or links or something.
Foursquare for example, when I signed in on my computer it sent me a text on my phone saying “Welcome to Foursquare ‘my-name’! Click here to download the app, and have fun exploring! https://foursquare.com/get“
Are there any books or sites (any resources) that can explain to me how to do this? I want to make an app that can send a text message like that. But I have no idea where to even start. I’m a front end developer so I only know easy code like HTML, CSS, JavaScript and PHP. I have programmed in java before as well, and I’m willing to learn any new programming languages for this.
Thanks!

The android API documentation is really easy to search..
