问题 I am using elasticsearch to get a faster geo distance search functionality for a web project with thousands of locations. The results should be sorted by distance.

We are trying to get a runner's position and track him during his workout with the watchposition() function of the geolocation api. On-screen the runner can check his current distance.

So we had the solution to store multiple

问题 I'm writing a daemon similar to Chris Alvares daemon. I want to get the divice location in background without users permission.
