GPS works better with google maps than my App android

I have an app in android using GoogleMaps API.
When i use google maps, I active gps and it find me so fast.
When i use my app, it takes some seconds, and if I'm in my house, gps dont find me. WHY ?
A short summary of my code:
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
MyLocationListener = new MyLocationListener();
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
7000,
5,
MyLocationListener
);
Thx for answers and sorry for my poor english
EDIT
Thx for answers ! the problem is that i dont want to use network provider. Wifi is exelent, and 3g have a 400 meters error jejeej.
I only want to know, why google maps, using GPS, find me in 1 second with perfect position Although I stay in a house.
Your answer is "use coarse locate". If google maps use network providers befor gps, its impossible he find me so fast. :(

GPS is using satelites, When you are indoor it can't get the signal from the satelites hence it can't find location (can't get a fix).
The GPS needs signals from at least 4 satelites to get a proper fix, that usually takes a few seconds, once you already have a fix you can maintaine it very easly. therfore if you are using google maps it will get you a fix faster.

You might want to use different location approachs for getting location indoor (coarse location could be the answer). I would also consider using the fused location by Google play services, it gives you a wrap up on the location providers and get you location based on what avilable at the time (meaning GPS, coarse - wifi or network).

You should try using Coarse locates for a quick locate followed by a fine locate to have a more accurate location. The coarse locate is usually very fast, while the fine one takes more time.
Basically, the idea is to do multiple locates and overriding the less accurate ones by the newer and more accurate locates.
You can find more info on the Android dev doc: http://developer.android.com/guide/topics/location/strategies.html
EDIT: if Google Maps is able to find you so fast, it is because you are not moving and they use the knowledge of the last location. Please read the above link that gives a lot of useful information for Location strategies (and it works very well).

RSSI signal from cellular network to be obtained in android application

I am a beginner in android developing and I am working on a project to create an app to locate cell phones without using GPS.Can anybody help me with how to get the RSSI for GSM and the distance if possible.Any code available for this purpose would be appreciated really.
I would also like to know, what other information can we get from the SIM card.

For SIM information including RSSI, you need to look at the Android Telephony and related APIs.
You can't get the distance from the base station though. You can get the Cell Id, which gives you a rough location if matched up to a database. Cell Id information is proprietary though, and publically available databases aren't always that accurate. Or you could use three Cell Ids + RSSIs to do a rough triangulation calculation yourself. The disadvantages with that are that many devices won't return cell info for the surrounding cells; you still need access to a reliable database of cell locations; ideally you should also include known WiFi hotspots; it's a lot of work to implement something that Android has already done.
Android handles location via its own location and location services APIs. LocationManager lets you choose the desired technology, e.g.NETWORK_PROVIDER or GPS_PROVIDER. So you could just choose not to use GPS, and let Android give you the best available result from the network.

How can I get rough location (country) forAndroid Tablets

I'm looking for a way to know the country-level location.
How to do it on a phone, or devices that have cellular network connectivity or GPS is clear. But what about devices that don't have that?
I know from Google Analytics that Google has that kind of location information,
How?
How can I get that information as well? Maybe from the play-store locale or something?
By "Tablets" I mean devices that have no GPS and no GSM / cellular network connection.

Use the WiFi aproximated location. It checks your IP adress and tries to locate it geographically.
please see this or this.
a quick summary of the WiFi location method form one of the posted links:
How it works: Unless you opt out, your phone is periodically sending anonymous data to Google with, among other things, your last known location and any Wi-Fi network you were connected to at the time. The accumulated data builds on a database begun by traveling Google Streetview cars that recorded Wi-Fi networks available along their routes (the cars no longer do this).
When using this method, your application will ask for the COARSE LOCATION permission on installation.

Since there's no clear indication (at least none that I've found) whether or not Google estimates location based on IP as a last resort, my 'getCountry' logic would be as follows:
Location location = LocationClient.getLastLocation()
If (location == null) location = getLocationByIp()
where getLocationByIP() will use a publicly available, RESTful free web service such as http://freegeoip.net/
Open to suggestions here. If line 2 is redundant I will be happy to drop it.

How to accuratly find other Android users within a radius of 200ft ( How did Color do it?)

I'm working on a app which requires that a device with this app installed will automatically find other users within a maximum radius of 200ft (worst case scenario 300ft, but that's pushing it) and/or a minimum radius of 40ft.
Ive tried the obvious solution of using GPS and a MYSQL query that query's our location table for other users within the 200ft radius, but as you probably would guess this is not incredibly accurate and if the device uploads coordinates that are off by over 200ft the server will return a list of users that are not within proximity. While I would prefer to just get the app to work the way it was meant to I'd rather the server return no users than false positives.
I know there's probably no simple way to do it accurately, but what other options do I have? And how did Color manage to do it? With all the tech in the avg smartphone and all the location based apps this has to be possible to do.

200ft (60m) is no Problem for GPS. Usually GPS is below 10m.
You even have a location.getAccuracy() method which you should evaluate
Just use GPS as your only location source. do not use cell tower location provider, when you want accuracy < 60m.
Of course inside a building, when you are sitting at your desktop GPS will not work, or is off by 60m.
GPS needs a view to open sky not obstructed (by dense materials).

Take a look at this question:
how to get the most accurate location using GPS and AGPS with given time in android?
Basically it depends on the phone's GPS and the current environment. Besides that, there's probably nothing you can do to further boost the location accuracy other than using GPS.

Do "x" based on GPS location or manual address (android /iDevice)

So I know next to nothing about GPS and Apps, but I do want to get my feet wet and have a (simple-ish in my mind) idea for a simple app based on GPS or manual address.
I basically need to know if you can do something like this
if GPS Location is (11.111/22.222) { Show(**THIS STUFF**) }
or if manual address is (555 Main St, Salem, OR) { Show(**THIS STUFF**)}
in android or iphone

You can. It's considerably more complex than that. And there are apps for both platforms that do exactly that. A quick search of Google, Apple Store, and Android Market will tell you what the current apps for that are.
If you want to do this yourself you will need to learn some new concepts. Geofencing (geographic buffers). Geolocation (address to coordinate conversion). And read up on how to efficiently use the location services provided by the devices you are writing for.

You should use android location api for GPS Location, and check in the onLocationChanged() method : if(myLocation.getLatitude==11.111 && mylocation.getLongitude==22.222)
On manual adress You should use android maps api.
