Android :: Google Maps & Apps With Mapview Have Different Current Positions

Jul 20, 2010

I have a mapview where I want to track the user's current location. GPS as well as 'use wireless networks' is activated in my phone settings.

Nevertheless, since I'm indoor I don't get a GPS fix, therefore the location is determined via network; wifi spot is available.

I have the Google Maps app running as well as my application running.

Strangely, the current location differes between Google Maps and my application, where the Google Maps is very accurate while in my app the location is somehow off a few 100 meters.

In my application I basically do the following (for debugging purposes now):

1) initially place one marker on the map: geopoint retrieved via locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

2) initially place another marker on the map: geopoint retrieved via locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

This will put the last known locations of both providers onto the map (eventually last known from outside my app).

3) then for the regular updates (since I don't get a GPS fix anyway indoor here), I do:

locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, baseLocationListener);

You can see for the frequency and distance I pass the 0 param in both cases.

In the app manifest, the following permissions are granted:

android.permission.ACCESS_COARSE_LOCATION
android.permission.ACCESS_FINE_LOCATION
android.permission.ACCESS_MOCK_LOCATION

Actually my baseLocationListener does get called, which I see in the log, but the updated location is somehow the same as the last known current position (of LocationManager.NETWORK_PROVIDER), same lat/lng.

I thought maybe I overlooked something or missed a parameter or setting, or my code has a bug. Therefore I installed some other (3 in total) LBS apps from the Android market that also show the current user's location. The current locations displayed in those apps are equals to the one in my application - and they're all some 100 meters off - but at least all the same.

See the screenshot here:

Now I am wondering:

1) as I understand, getLastKnowLocation is system-wide and not app-wide, why are there differences between the location in Google maps and all the other apps?

2) does Google Maps not update the lastKnownLocation of a provider?

3) does Google Maps use a different custom location provider (i.e. due to licensing reasons) other than GPS_PROVIDER or NETWORK_PROVIDER as they are in the SDK?

4) how do achieve the same accurate result with the NETWORK_PROVIDER like Google Maps does?

Android :: Google Maps & Apps With Mapview Have Different Current Positions Options

Jul 20, 2010

It seems that the problem is in the data quality of the different map provider that are used for Google Maps and MapView in SDK, which differ.

The map tiles coordinates don't seem to be very accurate, just like in the public google maps web api / tiles.

See this screenshot for an example, where I pinned the same geo point. http://img339.imageshack.us/i/gmaps2.png/

The map using the public map api is off a few hundred meters. Seems that we just have to live with it.

Android :: Load Markers Dynamically For Current Position In Android Google Maps?

Aug 5, 2010

I'm currently developing an app for Android which uses google map service. Because users will be able to see thousands of markers I would like to load only those which are currently within the map bounds (i.e. when user look at specific map tile). I know how to do it with javascript/html. However, Android doesn't seem to provide any similar methods such as containsLatLng(latlng) or getBounds (I only found getLatitudeSpan and getLongitudeSpan, but don't know how can I use them in order to achieve the similar effect). Can anyone give me some hint on that?

Android :: Com.google.android.apps.maps: Not Stopping

Nov 15, 2009

Has anyone else noticed a process that shows up as "com.google.android.apps.maps:" in TasKiller?

It does not seem to die and I have two copies of it in my task list.

It also appears that it has a second line of text that is not displayed... Maybe that is why it won't die?

I wanted to blame it on "Car Finder - Cinn Dev -CinnDev.com" but it still ran after an uninstall.

I have my location turned off in google maps as well as Latitude (I believe..)

For that matter, I never used Voice Dialer and Corporate Calendar. How do I turn them off?

I am facing to android application signing problem. My application contains Google MapView. When I compile the app and run on the emulator, MapView works fine. But signed the app, MapView doesn't work. I've get Google Map API. This works on the simulator. I could sign the app once 2 months ago. Then I've upgraded the app. Now I need to sign the app again. Actually I don't know why signed app's mapView doesn't work. How to fix it?

I used following steps when sign the app: Run Eclipse. Select the project. Right Click -> Android Tools -> Export Signed Application Package -> Then Filled forms. (In forms, Validity years: 200, and all passwords are same.)

Android :: Google Latitude Application For Access Through Google Maps?

Mar 5, 2009

Is Google Latitude available in the UK or not, because it doesn't seem to be working for me? I have received the RC9 update for G1 and have Google Maps 3.0. Is there an a Google Latitude application that I should have or do I access everything through Google Maps? When I go the www.google.com/latitude on my G1, it offers me the option of "launching" Latitude but it just takes me to Google Maps. From there, I cannot see the locations of my Google "friends" (who have agreed to show location), neither does my own location show up on the Latitude homepage on the web (I have settings turned to "detect my location automatically").

General :: Google Maps App Doesn't Sync Names With Google Bookmarks

Apr 17, 2013

I'm using the latest version of Google Maps on JB 4.2.2 [Nexus 4]..I noticed that I cannot edit the names of my locations in "My Places" in the phone app. So I used Google Bookmarks (google.com/bookmarks) from my PC to edit/rename My Places. However, the names do not sync or carry through to the Google Maps app on the phone. The names in the app are still the generic names, coordinates or street names.

Is there any way to change the names of My Places and get them to sync with the phone app? Really baffling!
