QR-GPS is a Plugin for popular app QR Droid. It adds ability to create a QR code from your current location, using your GPS or Network providers. Then, you can share that location easily.
This plugin can't be launched by itself. You need to get QR Droid 4.1 (or greater) for free in order to use it.
To make it short: QR-GPS Plugin and QR Droid, together, can get your GPS location automatically and generate a QR code from it.
