What options exist to update Android app setting remotely?
<p>I have an Android device that I'm using to monitor a couple of sensors with an app that I created.  What useful ways are there to update the settings in my app (while it's running at a remote location) from my computer?  I'm interested in sending a message to my app to tell it to email a screenshot, change sample rate, etc.  Creative workarounds are encouraged.</p>

<p>I've already looked into C2DM and unfortunately have no experience with setting up the required third-party application server.</p>
