I understand that Google used a wardriving kit in its Street View cars to bootstrap its map of wifi beacon landmarks.
But which data sources and methods do they use to discover and register new access points? Will they only feed in new BSSIDs submitted my Android phones with a valid GPS fix?
I set up two new APs (one of them dual 2.4/5GHz) and within two weeks Google had a fix for them, albeit 290m away from the real location. I will see if this fix will become more precise with time.
I’m fascinated by this but I didn’t find more details about how they do it.

Am new to android ,i want to create an android app to track indoor position using ips(wifi signals)
I need to know what are Prerequisites required for and the basic idea to develop it
You must have:
1) some wiFi antennas working around (minimum three to have the precise position in the room);
2) you must use your Wifi and check the power of each antenna.
Depending on the variations of these three levels of power, you can understand where you are. This is called triangulation.

Companies like Google and Garmin have a database of all speed limits of each road that they use on their GPS software. I would like to access and use this information. How would I go about doing that?
These companies either purchased, licensed or built their own map data, of which this information is part.
You might have some success with OpenStreetMap. YMMV.
Google has an API for road data. See this link: https://developers.google.com/maps/documentation/roads/speed-limits
I don't find it very accurate. Speed limit data can be updated via their Map Maker tool. Some of it may be gleaned off of the street view cameras, but not 100% sure that is how they collect it.
I'm also interested in learning Garmin's source for the data. I hear it is just as bad. Does Garmin have a similar API?

I want to get statistics such as the number of the installed apps and the number of active installs in a day.
How can I get the unique information of each mobile device?
When I have this unique information I can save it in MySql db with php and show statistics.
thanks all,I mean unique information Like UUID of Android phone
Most of the data you're looking for is provided by the Google Play service. Once you upload your APK, you'll start getting statistics on your app.
If you need more granular data, look into 'Flurry'. It's free, easy to set up, and quite powerful.
You can use this framework to track app statistics across various platforms:

I have a new app that I made and put in the store yesterday.
I am able to see it here: https://play.google.com/store/apps/details?id=com.problemio
but there is absolutely no way I can see it in the app store when I search for any terms. Any idea how I can get it to show up in the app store?
It says that the app IS compatible with my phone so I don't see why it wouldn't show up for me.
There are many reasons an application might be filtered for a given device. This is a good article that explains how the market will filter applications from a given device. You might want to read through that to find why you are not seeing the application. If the application is up on the website than it has been posted on the market so your app is being filtered for some reason.
