This has the benefit hat your app is not unresponsive during the query. (but I guess more than moving the map should not be allowed during it to avoid a unexpecting state (menu open) when the background process delivers the result)
Yep, I think I'll spawn a separate thread for the queries + transparent notification (something like "route lookup in progress") + maybe a cancel button. The queries are mostly pretty much instantaneous, BTW.

Modrana uses Google Directions for online routing and support for more routing providers is planed. The routing results do not dependent on the current map layer but on the current mode (can be set from the main menu under "mode"). This means, than when you set your mode as "car", you get a route for a car. When you use the "walk" mode, you get walking directions (if you ever wanted to walk from Prague to Sevastopol is just about 13 days ). The "bus" and "train" return results for public transportation and "bike" gets bike optimized routes. Not every routing option works everywhere, the most widely available are the car and walking ones.

right now i am a bit lost because i sometimes know where i am but don't really know the destination location on the map even though i have its address or generic location. having to scroll around the map to find the destination to route to isn't fun when you have no idea where to scroll to.
Yep, the current implementation is not perfect. I'd like to have it like this:
  • first you type an addres for start or destination
  • modRana geocodes the address
  • and returns a list of possible locations
  • you can check where each location is and choose one as the input for routing
  • you can also select a point near a location as routing input
    • example: you enter "Paris"
    • modRana shows where it thinks Paris is
    • then you choose from the map some place in Paris for routing
  • maybe a list of recently used addresses ?

Any other ideas for address routing improvements ?

BTW, in the current version you can already input geographic coordinates instead of an address.
