Android :: Android - Current Location From Best Available Provider

Mar 23, 2010

I have some Android code that needs to get the best available location QUICKLY, from GPS, network or whatever is available. Accuracy is less important than speed.

Getting the best available location is surely a really standard task. Yet I can't find any code to demonstrate it. The Android location code expects you to specify criteria, register for updates, and wait - which is fine if you have detailed criteria and don't mind waiting around.

But my app needs to work a bit more like the Maps app does when it first locates you - work from any available provider, and just check the location isn't wildly out of date or null.

I've attempted to roll my own code to do this, but am having problems. (It's inside an IntentService where an upload happens, if that makes any difference. I've included all the code for info.) What's wrong with this code?

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

Unfortunately, this finds the network provider, but only ever outputs latlng null 30 times - it never seems to get a location at all. I never even get a log statement of locationChanged.

It's funny, because from ddms I can see output like:

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

Seeming to suggest that the network provider does have some location info after all, I'm just not getting at it.

I think working example code would be a useful resource for the Android/StackOverflow community.

Draw Route Using Current Location From Device On Map Using GPS Provider

Sep 11, 2012

I'm working on a project to display a route in a MapView based on current location from GPS Provider. I'm able to draw the path between two points but the problem starts when the location changes to a new point causing the draw path to erase. Basically my Location Listener saves the current Geopoint and sets the new Geopoint location and after that it starts the overlay to draw a path based on those two points. I think an option could be saving the coordinates to a database and then pulling the information from there to draw the path.

private class MyLocationListener implements LocationListener {
public void onLocationChanged(Location location) {
Toast.makeText(getBaseContext(), "Tracking device..",
Toast.LENGTH_SHORT).show();
[code]....

Android :: Testing Location Using Network As Location Provider?

Jan 27, 2010

I have an application which uses the network as the location provider (rather than GPS eg.), however I can't seem to figure out how to send the emulator test coordinates. In DDMS I would usually send coordinates in the Emulator Control tab.Is there a place to simulate coordinates derived from the cell phone network provider?

Android :: Location Provider / Coarse Location

Jun 25, 2009

The way we are retrieving locations from our Android phones is to 1st get a Coarse Location followed by a Fine Location. This is for the case where the user may be inside a building initially and unable to track satellites. After we get our coarse location we transition to a fine location to track satellites. This method has been working fine for several months. We recently upgraded to 1.5 and our mapping application, to my recollection continued to work.For the past couple of days we have not been able to get a coarse location and we are receiving a status message in the onStatusChange callback of.We have re- installed previous versions our code that used 1.1 and we are receiving the same status message of .TEMPORARILY_UNAVAILABLE. Other than the obvious description of the constant, we can find no meaningful information.

Android :: Force Use Of Wi-Fi As Location Provider

Nov 23, 2010

As I understand it, I have three location providers to choose from: GPS, Network and Passive.

I would like to obtain my location by detecting the Wi-Fi network I'm connected to, I believe both Cell Triangulation and Wi-Fi location determination is covered under the Network provider.

However, despite being connected to a Wi-Fi access point, my program always seems to use cell triangulation rather than Wi-Fi to determine my location (assumed based on the huge inaccuracy of the returned coordinates).

It doesn't look like there's any way to force the use of Wi-Fi only? How does Android decide when to use Wi-Fi over cell triangulation?

HTC Desire :: Home Location Fixed Instead Of Current Location

Nov 14, 2010

How could I fix the location which appears on the clock on the home screen and serves as weather forecast location? I am not living near a big city listed on the weather location list and when at home, the current location usually is indicated some dozen miles away from my home. This could be a cosmetic problem, but in the Alps (where I am living) weather a short distance away can be quite different from where you are.
Besides that, it would be nice to know the weather at home while beeing abroad.

Android :: Fastest And Most Reliable Location Provider

Mar 31, 2010

I am working on an app that fetches localized data from the Web based on the user's long/lat. Currently I am querying the system for the best enabled provider [my criteria defines best basically as most precise--not sure if this is the best idea for my application, as at the point where I fetch data it really doesn't matter if the user is here or 3 miles from here.].. But anyhow, I'm curious as to what is most reliably the fastest Location provider? Network or GPS? My app hangs a bit "Acquiring your location" on my loading screen and I'd like to cut this wait time down as much as possible.

Android :: 1.6 Update - GPS Location Provider Stop Unexpectedly

Oct 22, 2009

Looks like I've run into some breakage from 1.5 to 1.6 after all. I am registering location listeners with LocationManager.requestLocationUpdates() With GPS as location provider, I run into a problem with navigation stopping by itself after a few seconds, just to return, stop again, in an endless cycle. I haven't seen this prior to 1.6 Donut and I have no clue what might cause this problem.

Here's the Logcat output:

10-21 21:53:09.147: DEBUG/libgps(74): PDSM_PD_EVENT_GPS_BEGIN 10-21 21:53:11.177: DEBUG/GpsLocationProvider(74): exceeded MIN_FIX_COUNT 10-21 21:53:11.177: DEBUG/GpsLocationProvider(74): stopNavigating 10-21 21:53:11.177: DEBUG/libgps(74): qct_gps_stop 10-21 21:53:11.187: DEBUG/libgps(74): PDSM_PD_EVENT_END 10-21 21:53:11.187: DEBUG/GpsLocationProvider(74): Releasing wakelock 10-21 21:53:13.097: DEBUG/dalvikvm(74): GC freed 2562 objects / 104912 bytes in 223ms 10-21 21:53:20.227: DEBUG/dalvikvm(74): GC freed 1345 objects / 51352 bytes in 236ms 10-21 21:53:21.180: DEBUG/GpsLocationProvider(74): ALARM_WAKEUP 10-21 21:53:21.187: DEBUG/GpsLocationProvider(74): startNavigating 10-21 21:53:21.187: DEBUG/libgps(74): qct_gps_set_position_mode = 1, fix_frequency = 10 10-21 21:53:21.187: DEBUG/libgps(74): qct_gps_start 10-21 21:53:21.207: DEBUG/GpsLocationProvider(74): Acquiring wakelock 10-21 21:53:22.147: DEBUG/libgps(74): PDSM_PD_EVENT_GPS_BEGIN 10-21 21:53:24.167: DEBUG/GpsLocationProvider(74): TTFF: 2978 10-21 21:53:27.287: DEBUG/dalvikvm(74): GC freed 1417 objects / 52512 bytes in 232ms 10-21 21:53:34.397: DEBUG/GpsLocationProvider(74): exceeded MIN_FIX_COUNT 10-21 21:53:34.397: DEBUG/GpsLocationProvider(74): stopNavigating (and so forth)

A web research for these logs didn't turn up anything (which is unusual in my experience), so this leads me to post the question here wondering what the root of the problem might be.

Android :: Get Current Location

Feb 23, 2010

I'm done creating an android program that adds a marker to a location. But I need to show CURRENT MY LOCATION in the MAP. I know this is done thru location based services but I don't know how to incorporate it into my program.

Here is my onCreate command:

CODE:.......

I have an onTouchEvent that places the marker. So no problem there, the problem is I need to display my location at the start of the program. It should show a mark that says, "You are here" or something like that in the map.

Android :: Need Most Robust Way To Get User's Current Location?

Jun 29, 2010

The LocationManager API in android seems like it's a bit of a pain to use for an application that only needs an occasional and rough approximation of the user's location.The app I'm working on isn't really a location app per se, but it does need to get the user's location in order to display a list of nearby businesses. It doesn't need to worry about if the user is moving around or anything like that.Show the user a list of nearby locations.Preload the user's location so that by the time I need it in Activity X, it will be available. Don't particularly care about accuracy or frequency of update. Just grabbing one location is sufficient as long as it's not way off. Maybe if I want to be fancy I'll update the location once every few mins or so, but it's not a huge priority.
Work for any device as long as it has either a GPS or a Network Location provider.

Android :: UNable To Get Update Current Location

Nov 17, 2010

I have an activity that needs to display an alert to user when location is updated,
but i need first to get current location (update last known location) and then start a location update listener to display alert in this activity.

Basically what i need is to display an alert if location changed from time activity was created.

If i use getLastKnownLocation when activity is created, it might be outdated, then the requestLocationUpdate listener is called a few seconds from activity creation time.

How can i do this?

Android :: Network Provider For Location Updates In Android GPS Gives Device Time?

While using network provider for location updates, I found that it is the same time that I set on my device. Can it not be that provided by network as it goes when it is GPS. Or if network provider cannot provide time , then atleast location.getTime() should return 0 instead of device time. Is there any way to avoid device time, as I want to distinguish it.
