i want to know my device location(co-ordinates) with respect to some known location(that could be location found by the device itself in the first) inside a building.
i used location services like network provider and gps but they are in accurate.

That is about as accurate as you will get. And plus, if you are using GPS on a phone such as the GS4, you get the latitude and longitude to about 8 decimal places, which should more than accurate enough, unless you are trying to measure centimeters of movement.

Agreed with tanishq.dubey that theres no real way to get more precise than GPS, unless you want to use the accelerometer to detect movement and calculate its displacement that way, but I'm not sure about the accuracy of the accelerometers, nor exactly what data they would give you to work with, so it may not be a viable option, but you can definitely try. Otherwise, use GPS, and a little bit of math (

Hope I helped!

OK, now I know that the GPS is software driven - i.e. you cannot manually turn it on or off. However, is there a package that will activate the GPS on the phone, and show a status display of the satellite constellation and how well or poorly the receiver is picking them up?
I'd grab SiRFtech, but the phone uses the Qualcom chipset, not the SiRF III chipset

there are tons of gps utils... for fast switching gps on and get fix search for the small prog "GPS test" i´m running version 1.04 don´t know if thats the latest
apps
well, even if it is from SirfTech, all GPSs support the NMEA protocol. if the app you showed also supports NMEA, then this is fine.
I normally use CruxView (attached), which is also quite simple, has some nice functions (+a dedicated SiRF section, which I'm not touching )
/edit: I guess your app supports NMEA - at least I see it listed in the menubar!
Thanks folks Much appreciated Should make figuring out what's wrong with the GPS on my TP2 a little easier - takes forever to get a lock, and even then bounces in and out like a chicken on a bungee rope on acid - and it only started doing that this week, three weeks after obtaining the phone, no less!
gps is a miracle
never got it to work right...never more than 3 sats outside on both kaiser and rhodium, inside no chance!
a week ago i installed gps test and navigon and i got best gps, fast fix and can navigate through my house!
i have just taken the plunge into cyanogen because of the OTA updates and with 7.0.3.1 they have fixed the GPS. this is a hugely important feature for me as I use gps to track my training logs on SportyPal. The gps works, but not great, and not as quickly as it did in sense and this affects the accuracy of recorded speed and distance.
I am wondering if there is a way to change the polling rate somewhere in the settings of cyanogen?
the examples i can offer are
sense polling - about 3-5secs apart

cyanogen polling - about 30sec to 1 min apart
these were taken only one day apart and the only difference is cyanogen.
thanks for any help!
You could try a different gps driver like this one and see if it polls more often? As far as I know, there is no way to currently configure the polling time.

Liking this so far, practically an instant lock.

THIS!!! man this worked great, thanks so much! i'm now completely sold on cyanogen!
Yeah I sent a PM to the guy suggesting he try to merge these drivers into cyanogen.
Is it possible to get the mobile signal strength on GT 7.7
I had try lots of ways but can't successful.
What you mean "get"? To get it as a function in your own app's code or just you want to see it?
Turn off WiFi and you'll see strength bars in notification popup (on the place where you usually see WiFi signal bars).
There are plenty of apps like this one that display signal info:
https://market.android.com/details?id=com.cellsignaltester.moby
You can also get that in the About page of the device settings. What exactly are you after?
nooooo, use this one instead, this Widget is better

It's all the same data obtained from the phone. A widget tends to suck battery and performance so that's why I recommended a simpler app. Since there are a ton of them, it's really incumbent on the end user to decide what they like.
All of that apps doesn't work on SGS2/Tab7.7 (Exynos-based chipsets).
No, they work (run), but unable to show correct signal level due to a "bug" in modem FW. They always show +85dbm. So the only way to see correct signal strength is the system signal meter in statusbar.
Any way to update the modem driver to fix the Bug ?

Don't think so. Samsung does not care about it - still not fixed even on SGS2, which is already on the market for a long time. Maybe it will be fixed with ICS release, nobody knows.
Become A SECRET SPY! (GPS Tracker)Being a Father of 17 children with 5 more on the way, I can get lost when trying to keep track of what everyone is up to. Several of my children have cars and are gone to wherever they go most of the time. I've thought about picking up one of those GPS trackers that I can stick to their car. These are fine, but they don't have all of the features that I need. You know what does? Any Android phone! The phone doesn't even need to have service to work the way I want it to. Let me explain.
So I need a device that can track and log the GPS data of a moving car. I also want it to be able to connect to open WiFi networks and send me the data once it has the connection. So first thing we need is to find some apps that will help us out with this.

Download GPS Tracker
Download WiFi Automatic
Start by downloading these two apps. WiFi Automatic will help your Android device connect to any open network. Then GPS Tracker will upload the data to a website where you can login and take a peep on what's going on.
Make sure to set the phone on silent and turn off anything that could drain the battery. Kill your Bluetooth, NFC, Notifications and uninstall any apps that might try to sync data once you've got a connection. We don't need facebook soaking up all of the bandwidth.
Now grab some duct tape and smash this DIY FBI CIA BLACKWATER GPS device onto the bottom on the target car. Then go to your computer, login to the GPS Tracker website and wait for the secret data to start flowing in.
Hey guys,
Hoping for some help here. My GPS seems to be working fine except for the compass feature, which seems to show off by about 30+ degrees. This makes walking navigation a bit of a challenge because we always seem to be questioning which way we should turn, especially when we get out of a subway (we're currently travelling in Japan).
When I turn on a compass specific app, the problem fixes itself and translates over to Google Maps but as soon as I try to pinpoint my location and direction using Google Maps, it reverts to being off by 30+ degrees or so.
The screen capture shows you what I'm talking about.
In real life, I am standing directly facing the river, which is what the GPS shows after I use the Compass app. When I use Google Maps' direction, it reverts back to being off axis. At the 15s mark, you can see the Compass app recorrecting the accuracy by swinging the compass back to its true direction.

Has anyone seen this before and does anyone have a fix?
GPS has no idea what direction you're facing. It knows your position on Earth and can calculate your direction of movement and speed based on position readings over time, but it has no way of knowing what direction you're facing.

Phones usually have a compass for orientation.
What I do to calibrate it is what Google maps suggests, draw some 8 symbols on the air with the phone while you rotate it.
Like this:

"lightbox_next": "Next",
"lightbox_previous": "Previous",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After that, compass should work fine for some hours.
