java - get distance between two places -

-

i trying find distance between 2 places, new this. came know openstreetmap. not sure do.

i found traveling salesman application uses osm route. here question how osm between places .e.g. "http://www.openstreetmap.org/api/0.6/map?bbox=10,30,10,30" gives me map of box (10,30,10,30) .. if want map between leeds , sheffield should query.

or there other way find distance.(as student want open source way academic project..)

please suggest..

for calculating routing distance between 2 places can use 1 of various online or offline routers. there list of various information routing developers containing list of libraries , other information.

if have obtain location of specific address before doing actual routing can use nominatim.

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
