How to display my location on Google Maps for Android API v2

由 空扰寡人 提交于 2019-11-27 09:31:34
问题 I've looked high and low for an answer on this, and no one, in any forum question has been able to help. I've searched through the tutorials. The API Guide says: The My Location button appears in the top right corner of the screen only when the My Location layer is enabled. So I've been looking for this My Location layer and have been unable to find anything. How do I show my location on a Google Map? 回答1: The API Guide has it all wrong (really Google?). With Maps API v2 you do not need to

how to convert between degrees, minutes, seconds to Decimal coordinates

由 ぃ、小莉子 提交于 2019-11-27 08:22:09
Looking for a java utility. It is even better if you can tell me how to do it using geotools library. By "Decimal coordinates" do you mean latitude and longitude (also known as the decimal degree)? If so, what you're trying to do is pretty easy: Given a DMS (Degrees, Minutes, Seconds) coordinate such as W87°43′41″, it's trivial to convert it to a number of decimal degrees using the following method: Calculate the total number of seconds, 43′41″ = (43*60 + 41) = 2621 seconds. The fractional part is total number of seconds divided by 3600. 2621 / 3600 = ~0.728056 Add fractional degrees to whole

I know how to get the cell id but I couldn't do triangulation. 回答1: If you can do an HTTP Post to an arbitray website, you can use Google's geolocation api.

See the above link on how to add more information to your json from wifi etc. to greatly increase the accuracy of the result. And pay special attention to the mobile country code,

Identifying country by IP address

由 此生再无相见时 提交于 2019-11-27 07:24:33
Is there a way to figure out the country name just by looking at an IP address? I mean, do countries have specific ranges of IP addresses? For example, Australia can have IP addresses only in the range of 123.45.56.89 - 231.54.65.98 (just an example) Chris Gessler I think what you're looking for is an IP Geolocation database or service provider. There are many out there and some are free (get what you pay for). Although I haven't used this service before, it claims to be in real-time. https://kickfire.com/kf-api But just do a google search on IP geo and you'll get more results than you need.
