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:

http://img33.imageshack.us/img33/8679/mapproblem.png

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 :: Can't Find/import The Com.google.android.maps Library/package?

Jan 3, 2010

I'm learning via a few books w/downloadable code. One of the examples I'd like to get running won't even compile because the IDE can't find/import the com.google.android.maps library/package, which I found odd since I have everything possible installed that the SDK offers. The book info on the publisher site was not helpful either.

I'm using Eclipse (build 20090920-1017) with the ADT 0.9.5 plugin. SDK is fully updated (all available packages installed, including android 1.1 api 2 rev. 1 through android 2.0.1 api6 rev 1, and google apis 3 rev 3 through 6 rev 1.)

Android :: Out Of Memory Error When Using Google Maps API

Sep 29, 2010

I have an application here that has a feature of showing a POI on the map. It's only one POI and it is only drawn when it's actually within the visible screen area. It works perfectly for a while but if I play around zooming in and out and dragging, it will eventually crash. According to Logcat, the reason is always an OutOfMemory error.

At first, I thought it was a bug on the Google Maps API. After some researching and seeing some Romain Guy posts, I was kind of convinced that I had done something stupid on my app that kept me running out of memory from time to time. Then I ran some more detailed tests with Heap Analyzer (Eclipse) on and I saw that even though I had 2+, sometimes 3+ megabytes left of free memory, I was still getting those annoyings Force Close messages caused by OutOfMemoryError. Most of the times it crashes when trying to alocate some 614kb chunk of memory regardless of how much I have left.

This problem happens a lot on Nexus One 2.2.1 and on HTC Evo 2.1. After some little testing, I got no crash neither on G1 1.6 nor Samsung Galaxy S i9000 2.1. But I cannot say for sure the G1 and Galaxy will not show this problem after more testing. I can only think of a memory fragmentation problem. I hope this problem has a solution. I will also be glad if I can just catch this error and prevent the app from crashing.................

HTC EVO 4G :: Google Maps Location Error?

Jun 26, 2010

Is anyone having issues with Google Maps being able to pinpoint your exact location while using the Evo?I used to use Google Maps all the time on my MyTouch, and it would always find my exact location with no problem. But I used it for the first time today on my Evo, and it was always a couple of streets off (not "general" location with the transparent blue circle, but "exact" location w/no circle). This is very inconvenient when using Navigation because it keeps wanting to redirect from a place that I'm not at.I made sure my GPS was on before I started using Maps. I haven't tried using Sprint Nav or any other Nav apps, so I'm not sure if it's a problem with Google Maps, or the Evo GPS.

Motorola Droid X :: Car Dock And Google Maps Navigation Error

Jul 22, 2010

Just got off the phone with two VZW reps who couldn't give me an answer and suggested that I use VZ Navigator since Verizon can support that software, LOL. My Problem: Used Google Maps Navigator for the first time today. Was using my Motorola Car Dock I purchased and got the address put in and everything then tapped "Navigate". Si there I am and have my nice map view of the route I'm taking and every 30 or so seconds it would flip to a grey screen with multiple tiered options, first of which was "my location" and the address. Below that was the option to tap "Navigate" again which took me back to the map view as it should be. Problem is that it just kept popping back into the grey tier screen every 30 or so seconds. I took it off the dock and this doesn't seem to be happening while not on the dock although I get another message telling me to detach the charger from the wall to conserve battery...WTF? After speaking in depth with VZW reps they seem clueless. First rep told me to try and uninstall Google maps and reinstall (which come to find out I can't do after speaking to the second rep) while the second rep seemed to want to glorify his Droid Incredible and how great it was over the Droid X. he offered to reset my phone but advised I would have to sync all my contacts again, redo all my widgets and reconfigure all my e-mail addresses. Anybody else experiencing this problem with the car Dock and Google Navigation?

I'm using a Spice Mi-350 phone (It is the same as Lenovo A60). On the stock Google Maps worked perfectly. But recently i flashed Yonip 5.3.7 Rebirth ROM. Since then Google Maps does not work anymore.

Android :: How To Import Individual Projects From Source Code?

Jul 13, 2010

As far as I understand, all the built-in standard apps like (email, music, calendar etc) are built using the same API. So I should be able to import a project like mail / music etc without checking out the full source repository of android. I'v been trying that but I am getting compilation problems like class resolve failure. Am I doing it wrong? What do I have to do to import a project in eclipse without compilation error. I am interested in the Music application.I have setup the latest android eclipse plugin and run test applications with it, so my setup is OK.

Android :: Weird MapView - PixelConverter Error

Sep 28, 2010

I have an application based on the MapActivity. The application drops ItemizedOverlay items on the map as you start to move about. It has been running with no problems until I dropped it into a Nexus 2.2 phone.

I'm running into a weird problem where sometimes when I zoom in/out too fast, or pan too fast, the MapView will go "white" and my Overlay items will get shoved into the upper left hand corner.

The only error I've seen in my log is:

CODE:..........

My Map keys are working fine. I have internet permissions setup on the phone too.

I'm scratching my head over this one.
