title: Is it possible to send a message from one app to another?
body: <p>I have a text messaging app that I want users to be able to text another app of mine on someone else's phone that will show up within the app. Printed on screen. I have one app that will send the message and one app on the receiving device that will display the message. How would I go about doing this?</p>
  
  <p>The receiving app is an opengl app that will display the message in front of a 3d model from the sending app.</p>
  
  <p>If someone could help me out or get me going in the right direction, I would greatly appreciate it. Thank you for your time.</p>
  
  <p>EDIT: This is what I'm doing. I'm making a live wallpaper that women can put on their phone, a seperate "regular" app will allow the husband, fiance, etc to send a message to the lwp on the significant others phone that will display at the top half of the lwp screen.</p>
