i need to know about the LocationListener() working in the real time. Does it expect the user(device) to move in order to update the current location details or it automatically updates when ever the gps is enabled? Another query is regarding the getLastKnownLocation(). When is that last known location will be lost and thus returns null... (in realtime).

View 2 Replies View RelatedI'm trying to develop a small app, that can retrieve GPS coordinates, and store them, so I can retrace the path I took. The thing is, the GPS on Android emulator is kind of screwing around with my nerves... First of all, the Mock Position system doesn't work, so I'm manually fixing the coordinates with telnet "geo fix" command. Second of all, the location listener seems to not be refreshing. I'm lauching the app, fixing a first set of coordinates, and observing the response I expect. But when I push a second set of coordinates, the app simply doesn't react.
I tried a lot -big lot- of ideas on this, and I'm kind of running short...
By the way, I'm developping on Eclipse with ADT, and the SDK for Android 1.5 (French HTC Heros are still with Android 1.5) so that I can use my own app.
Here's my code (just the coordinate retrieval part) :
CODE:.................
The application under development was to distinguish between the current location of the android phone based upon GPS signal when it was available. When it is not available, alternate methods are being used to distinguish the user's location. The application uses a private locationlistener class that implements the LocationListener class. The code within the onLocationChanged( ) method to be overridden will draw the location on the google map as a dot as they are received.
I have noticed however that something is amiss. If you start outside the building, it will estimate your position with several dots around your current location. When you walk through a building where you don't get GPS, the dots are not drawn as expected, but as soon as you step outside again on the other side of the building it rapidly draws dots far away from (but leading up to) your location, until it gets to your actual current location. I don't understand how these other values are retrieved and why they seem to poke their ugly heads in, once the user steps back outside............
I am having issues regarding a LocationListener in my Service called myService.
Here is my code:
///onStart method ..
onStart() {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE)
.
.
provider = locationManager.getBestProvider(criteria, true);
locationListener = (LocationListener) new MyLocationListener();
locationManager.requestLocationUpdates(provider, 0, 0, locationListener);
}
In my Activity there is a button which should stop the service. On the click of the button I am doing:
stopService(new Intent(getApplicationContext(), myService.class).................
I have a Service that uses the LocationListener, and it will be running from boot, indefinitely. My question is, how often is too often to listen for location updates? Is 5 minutes a battery killer? What about 1?
View 1 Replies View Relatedyou can subscribe to requestLocationUpdates via two ways one by specifing a PendingIntent the other is by using a LocationListener. When is advised the one and when the other?
View 1 Replies View RelatedI have an android application. Based on the current geo location of user, I want to fetch some remote data in background and store it. My implementation is: At specific interval a alarm fires up my service. Service uses an anonymous class to query current location and registers a locationListener callback. On call of onLocationChanged() I initiate the remote data fetch from server.
However once my service is done registering the location listener using anonymos class, it returns as expected; as it doesn't wait for callback to happen before finishing. Since callback takes some time and makes a call when service has already returned, it throws an error saying: java.lang.RuntimeException: Handler{43e82510} sending message to a Handler on a dead thread
Which is quite understandable. One quick workaround for me now is that I can use getLastKnownLocation from locationManager as that doesn't respond back by callback; but what if I do want the latest location right now, in a service and not activity? How can I wait for callback to happen and stop my service from returning.
Also, at what point does lastKnownlocation gets updated? Everytime GPS registers a new location; does it update it? What I want to know is that if it's not latest can it still be closed to latest? As I didn't see an option in android emulator to configure the time period between subsequent updates.
I had filed a similar issue about location services not working properly in emulator. However after I upgraded my droid phone to 2.2, I am finding that location services are not showing the correct location. Though the coordinates looks correct, it is showing my location as San Jose while I stay in Los Gatos. Therefore my local search query gives me result based on San Jose.
View 6 Replies View RelatedWe have an application that is restricted to one country (Norway). But I am sitting here with multiple devices, HTC Wildfire, SE XP10 (after 2.1 upgrade) and SE XP 10 Mini (after 2.1 upgrade) that fails to find the application even though they are registered on a Norwegian network (Tele2). The SE devices found the application before they got the 2.1 upgrade, and I have lots of other devices (Nexus One, HTC Desire, HTC Tattoo, Galaxy Tab) that finds the app without any problems.
This is very important for us since we can't enable the app worldwide due to copyright issues, so is there any way to resolve this issue? Is it the operator or the Android device that fails to report the correct country here?
I am struggling a bit with the LocationListener in Android.I want to make an app that will get the current GPS location, and then afterwards sleep for a long time. A day or more. In this period of time i want the GPS notification icon to not show.What i have now, is in the onLocationChanged a Thread.sleep(x) but this will keep the icon on in the sleep period. How can i do this, and is there a better approach than to use Thread.sleep?
View 1 Replies View RelatedI am working on an Location Based Application. In this application i am using LocationListener class to update the location when the Location is changed.In each Activity i have different LocationListener to update location and do some specific work on updated location. But my problem is that when i am changing my location through DDMS , the LocationListener is being called of that current Activity as well as all the activities of the whole application where LocationListener has been defined. I don't know whether there should be one LocationListener for the whole application or for each Activity we should have different LocationListener.
View 1 Replies View RelatedIs there a way to manually trigger the code inside a LocationListener's onLocationChanged method? It should receive a Location object with the last known location, I guess.
View 2 Replies View RelatedHow do I unsubscribe a LocationListener from recieving updates from the LocationManager?
mLocationManager = (LocationManager)this.getSystemService(LOCATION_SERVICE);
mListener = new LocationListener() {
public void onLocationChanged(Location location) {
Log.i("LocationListener", "Logging Change");
}
}
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
5000, 1, mListener);
After I have exited the the view that created the LocationListener I am still getting log messages in the LogCat window. I understand that this is because I am orphaning the listener but I cannot see any destory method on the LocationListener nor can I see any "remove listener" style methods on the LocationManager object.
I'm working on a 1.5 Android application. Developing in Eclipse 3.4.2 on Windows XP. I have a MapView, have requested updates, etc.
The problem is that after the first manually injected GPS coordinate, the app stops recognizing that a GPS coord has been sent.
CODE:..........
Then MyLocationListener simply changes the value in a TextView to match the new GPS coordinate.
CODE:..........
I added some logging in the onLocationChanged method and it only ever sees a Location the first time that I attempt to send an update. All subsequent ones don't fire the onLocationChanged method.
Additional info:
The logcat output is as follows:
10-02 17:22:34.423: INFO/gps(6671): Provider gps is has status changed to 1. Extras: Bundle[mParcelledData.dataSize=52]
First GPS update is faked:
CODE:............
According to http://developer.android.com/reference/android/location/LocationProvider.html#AVAILABLE , that 2 maps to "Available".
As soon as that "Available" gets set, no other locations get passed through. Seems a bit counterintuitive.
I have a moment as I traded my Hero in to give it a try since my hero ended up with dead lines on the screen.For the life of me, I cannot get wireless or GPS location services to work.If I use wireless, google maps puts me somewhere over in China and if I try GPS, it never locks.In sprint nav with wireless, I am in Virgina (I'm in Michigan) and GPS never locks. I tried the trick I learned on the hero to disable wireless services until I get a GPS lock at least once, but even that didn't work.

View 2 Replies View RelatedI've set up reminders for home and work. On some occasions I will get the reminder after I have been at the location after an hour or more, and sometimes I don't get notified at all? It's showing my location accurately on the phone- just the reminders aren't working correctly. Is this actually working? I mean, if you go to a location wtih a reminder, do you a) get a reminder, and b) a reminder right away- not hours after you've arrived at the location? I need to determine if it's not working yet, or if I may have an interfering app... I'm running stock JB 4.1.2 with Verizon on a Samsung S3 phone.

View 3 Replies View RelatedI'm developing a mapping app using Eclipse 3.5.I'm setting the minimum update period with the LocationManager's requestLocationUpdates method, via a configuration activity. When I set the property I see in Logcat that the system process sets the value OK.When I actually send a new location from the DDMS emulator control and the location changes on the map view, I see that the system process then sets the minimum time to zero.Below is a capture of the system's log messages. You can see that I'm setting the period to 32 seconds, then 16, then, after I've sent a simulated location change the system sets it to zero.The map responds to location changes to location changes instantly even if they are sent only a couple of seconds apart.

locationListener = new MyLocationListener();
lm.requestLocationUpdates( LocationManager.GPS_PROVIDER,0,0,locationListener); if(!information.equals(null)){ Bundle bundle = new Bundle(); bundle.putString("hello", information); Intent intent = new Intent(LocationActivity.this, MainActivity.class); intent.putExtras(bundle); startActivity(intent); }
and in the locationlistener class
public void onLocationChanged(Location loc) { if (loc != null) { double lat=loc.getLatitude(); double lon=loc.getLongitude(); information = " "+lat +lon; Toast.makeText(getBaseContext(), "Location Changed:"+information, Toast.LENGTH_LONG).show(); } else information="bad luck"; }
The mainactivity then displays that...but its not happening...could some one please help me how to get the values of this.
