I created an application using Android GPS. This application shows user's current location name, latitude and longitude, GPS accuracy in Android mobile. I have tested this application in my android device. It was run in my mobile perfectly. But I can not get location name, latitude, longitude and accuracy when I was in Home or building. How do I create Toast text when I am not getting GPS coverage?
Thanks.
GPS works by connecting to four or more satellites and then triangulating your location by measuring the time it takes for the signal from various satellites to reach you, in a nutshell.
Due to this, you must have a clear view of the sky (sometimes even clouds can interfere), and GPS is unreliable and usually not working inside buildings and in underground locations.
Try using a different form of location tracking like the cell network for tracking the users inside buildings.

I added a test provider using LocationManager.GPS_PROVIDER as provider name like described here
https://mobiarch.wordpress.com/2012/07/17/testing-with-mock-location-data-in-android/
In Google Maps app, I see location jumping between mocked location and real location, and then back to mocked location.
Why is jumping to real location and how can I stop it?
Maybe I misunderstand how to use mock locations. I haven't found any official documentation available.
You most likely have your location settings configured in a way that your phone (and apps) can use both the location from the GPS sensor and the location from the cells and wi-fi. Since the coming of the Fused Location Provider, the way the system fetches your location got a bit murkier.
When you mock the position you are only able to mock the GPS sensor readings (this is also true for when you mock the position through the simulator settings).
So when the system feeds Google Maps with a position from the GPS sensor it gives it the fake one, and when it provides the position from other sensors it will be the real one.
To test that I'm correct, you can switch location settings to "Device only" and you should only get the fake positions.
Unfortunately there's no way to mock the other sensors readings.
Turn off Wi-Fi scanning / Bluetooth scanning in the Location Settings to stop jumping to preserve mock location.
I'm just wondering if it's possible to get an approximate location when the Location services on the phone is turned off.
For example, when I turn off my Location and open Google Maps, it shows my location in about a 2km radius. Then I can set start and end points for navigation.
In my own app, how can I do something similar? i.e. show their locality rather than just a map of India
Hi i am working on a real time location tracking application where i have used Fused Location provider Api. I was able to get the location updates when the device is moving. But i was also able to get the location updates even if the device is stationary on a table when i am indoor. So I have calculated the distance between the last location and the current location triggered in Onlocationchanged event and checked whether the distance is less than 30 metres, to know the device is actually moving. But sometimes the distance i get is greater than 400 metres (indoor/Device is Stationary). How Can i ignore the onlocationchange event when i am indoor? Any suggestions are appreciated.Thanks in advance.
Unfortunately I don't believe there's much you can do about it.
The reason you see those updates with great changes it's because indoors, you won't get a GPS lock, so the device is relying on cell tower and WiFi hotspot triangulation to determine your location, and something around 200m to 1km is the best you'll get with this kind of technology.
A possible attempt to hack-around it would be to:
check the source and precision of the location update
use the activity recognition API to guess if the device really moved
but both are a hack, around the technology limitation and might not be as reliable.
I've got an app which sets up two location listeners (one for GPS and one for network) and then chooses the location from the best one available, which should be GPS. However, if GPS is turned on, it will always choose the GPS location, even if the person starts the app up indoors. This has led to the GPS location being used even if the last known GPS location is from miles away and the network location is actually much more accurate.
Is there any way around this issue or is it just something that will need to be accepted as an issue with using GPS & network? Is the standard practice just to assume that GPS is always more accurate even though it's possible that it might not be in certain instances?
If you are using the network provider to fetch the location they are not very accurate when compared to GPS. So it can be a good idea to fetch the accuracy of your position using network provider when you are indoors as GPS doesnt function well indoors and you can use GPS to get the location updates when you are outdoor.
You can use GetAccuracy() method of Location class and see for the value it returns. Let Say if getAccuracy() retruns 25 then you can leave this value wait for another gps value until you get the desired value. Remember the value it returns is the radius of the circle in meters.
I am developing a android application in that i want find the user location using GPS. That is working fine .But if the GPS is Disabled means i want to find the user location based on the CellID and Loc .It is possible or not
It is possible means please tell me how to do that with sample code
Waiting for reply
Just request the "best" location provider, and you'll either get the GPS if it's available or the network (wifi / cell) if it's not.
LocationManager.getBestProvider()
You don't need to explicitly code to either GPS / network providers.
Here is complete tutorial of Location-Based Services Using CellID in Android.
