Google and others like Apple and Skyhook build a Database which links WLAN BSSIDs to a geographic location. A BSSID is like the MAC Address of a access point that gets broadcasted by that access point. It is therefore "public viewable" if the BSSID broadcast is enabled, which is the default for most access points. The BSSID operates on a lower layer as the ...

If I'm not mistaken it is to access Google's (presumably large) wireless MAC address location database which like Skyhook (a competing service, also previously used on iOS devices) allows a handset to scan for wireless networks nearby and send their MAC addresses (possibly SSIDs as well, I haven't looked into it too depply) off to Google to compare to their ...

You might be interested in Assisted GPS Assistance falls into two categories: Information used to more quickly acquire satellites It can supply orbital data or almanac for the GPS satellites to the GPS receiver, enabling the GPS receiver to lock to the satellites more rapidly in some cases.

First, I suggest you stop using your task killers. They are draining your battery more than saving it. The System is restarting the services when they need to run which is causing battery usage. Second, you are under the assumption that freeing up memory is a good thing. It is not. Freeing up memory is not going to decrease battery usage. What you really ...

It turns out that just because you can see and use a map online, that doesn't mean that Google will allow you to make the area available offline. Offline maps are only currently available for certain countries, and Brazil isn't currently one of them, in fact it seems to be a fairly odd selection. Google have published the full list of countries that it's ...

Have you thought about un-installing and re-installing Maps as a possible solution? First, get rid of the pre-loaded Maps by deleting the /system/app/Maps.apk file: su rm /system/app/Maps.apk Once a system app is updated, it's useless in the /system/app folder and can be safely deleted. Then copy the current Maps version to your SD Card: cp ...

The latest Google Maps app has the navigation function in-built. The navigation "app" was always integrated into Maps. The blue icon was just a separate entry point into that maps.

You are probably not in the US, right? Seems that Google Maps 5.0 is not yet available in many countries (just like Google Reader for Android). Meanwhile, you can use a link to the .apk file here: http://thegadgets.net/technology-news/download-google-maps-5-0-apk/ Download the apk file, copy to the SD card, and open with e.g. Linda File Manager. Hope this ...

GPS doesn't understand static direction at all; it can only infer direction from motion. But there is an electronic compass inside the phone as well as the GPS. You might want to download the "GPS Status + Tools" program from the Market; you can see detailed status information for both the GPS and the compass.

Places is part of Google Maps (and was introduced with Maps 4.4 about a year ago), you should be able to see and search for all the same businesses and attractions in the main Google Maps app, Places just puts a nicer interface on it. Much of the data came from what used to be called Google Local. Businesses can add themselves to Local/Maps/Places and ...

There are a number of possible reasons for an inaccurate location, mostly relating to the lack of a good GPS fix. If the phone cannot get an accurate GPS fix, it will use more approximate methods of deriving its location - such as cell tower locations and wifi hotspot locations. Possible reasons for no good GPS fix, in vague descending order of likliness: ...

To see alternate routes, you need to use Navigation as opposed to Maps. If you already have Maps open, click the blue arrowhead in the upper right to switch to Navigation, then click the context button on your phone, then select Route Info, then click the third button to the right along the bottom which will have both a dashed and solid line going to a map ...

This is not possible at the moment (but maybe in the near future). Reason: Google maps data is stored as raster image tiles without any meta information (street vectors, streetnames, interceptions and so on) besides the geolocation per tile. This means routes cannot even be calculated offline even if someone wants to. Maps is deliberatly an online service, ...

If your device is rooted, you can use Titanium Backup to backup the Maps application, which will backup the application and it's data. After resetting, again install Titanium Backup, (you have to root again, if you had lost the root access, as a first step) and restore the Maps application. While restoring, you get a chance to opt for restoring app alone or ...

Update: Apparently there was enough of a hue and cry about it that they've added a button, although "ok maps" will still work. Not the same as the old offline maps, but better than nothing I suppose. Having come under fire for (mostly) removing the option to save offline maps in its new Android app, Google has pushed a new update that makes it easier ...

This won't answer your question for Google Maps, specifically, but have you tried using an offline map application such as MapDroyd? Would that suit your needs? You download the entire map beforehand and therefore wouldn't have to use your data to view the map.

3D maps includes 3D models of some cities. London isn't included, yet, but New York is, as are Cardiff and Birmingham on the UK. You don't need to do anything to view them other than select the map layer, zoom right in, and then swipe down with 2 fingers to angle the view. (the 3D models appear if you're looking straight down, but it misses the point, ...
