I'm trying to get a location from lat /lon values with the getFromLocation function:
adresses = geocoder.getFromLocation(lat, lon, 1); // Search addresses
The function should return a empty List, if it don't find an address, but it throws the NullPointerException. What can/must I do to fix it?
I have an activity that implements LocationListener in my application and my onLocationChanged method has been working perfectly up until recently. For some reason the Location object being passed into the method is null. My question is, why is it null? Does it pass in a null object if it cannot acquire a location?
My GPS is on and I have it set to pull a location from the GPS, and I know my GPS can get a fix on me as I used Maps and had it locate me.
Also, I have the permission for my app set as:
CODE:.................
I don't believe permissions is the issue though, as my activity was working beforehand and I have not altered the permissions since then.
Here is the code that determines the provider of the location object:
CODE:.............
Here is the LogCat output of the error:
CODE:..............
I have tested the same code on another device (an HTC MyTouch 3G to be precise) and it works flawlessly with the GPS, however on my Motorola Droid it crashes.
I'm looking to test some code I've written and to do so I need to construct a variable of type Location and to give it a long / lat value but I'm unsure how I would do so.
View 1 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.
View 1 Replies View RelatedIn my application I have to fetch the current location. First it correctly fetches the location. But we are moving from the current location to some other location. It shows the previous address. It is not updating the location. My code is: locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); locListener = new MyLocationListener();locManager.requestLocationUpdates(LocationManager .GPS_PROVIDER ,0,0,locListener); location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location != null){latitude = location.getLatitude();longitude = location.getLongitude();} Please find the mistake and when i launch first time it is not working on second time itself it is working so check this thing also.
View 1 Replies View RelatedI 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?

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.
View 2 Replies View RelatedRecently all my android devices think they are in Spain when I am at home in Toronto.
I think this was caused when I ran a location spoofing program on only one of my devices, one of the locations I set it to was Spain (among others).
I've tried clearing the data for the Network Location apps, changing the SSID on my router with no luck.
The only way it shows the correct location is when I go outside and run Google maps long enough to get a GPS fix. But when I go back inside I am back in Spain!

Is there any way to specify the time intervals that the Location Manager broadcasts the current location?

I've found bits and pieces of this answer scattered through other posts, but I wanted to record it here for others.How can I simply request the user's GPS and/or Network location and, if they haven't enabled the service, prompt them to do so?
View 1 Replies View RelatedHow 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.
i've had my phone about 3 weeks now. up until last week, the htc weather widget would update to my current location. when i was home, it would show the town i live in. i also had the google internet option to use my location and this would also work perfectly until last sunday.now, the weather location was stuck on miami no matter where i went (as far north as west palm beach) and the internet shows up 'location unavailable'. i have found out that the gps is picking up where i am in goggle maps but it seems that the cell towers are not as far as weather and internet location are concerned. i have tried all of the obvious settings.i did a factory reset and now my weather says ft lauderdale which is closer to me but still not my town. it does not update (manually either) as i move. the internet location still says location unavailable although for a fleeting minute after the factory reset, it DID locate me....then it was gone so i called verizon, they didn't have a clue. then i took it to the store and it turns out EVERY phone the tech tried in the store had the same problem, including his. he told me it was a google problem and there was nothing he could do about it. i felt if i tried explaining how that would make it a verizon problem as well, it would be a losing battle

Is there an equivalent to Java's null layout in Android? Basically I want to specify the x and y coordinates of each component and not have the layout manager choose where they go. They will be within a scroll pane so it doesn't matter whether they fit on the screen.
I know null layouts are generally not a good idea but I have a special case where I need it. I'm porting a Java TV guide app and the program grid is made up of JLabels. The program dynamically generates them all, setting the x and y coords based on start/end time and channel. Each program could start and end at any time so as far as I know a table layout won't work.
I have a picture in the setImageResource, but I want to make it null; so far I am using i.setImageResource(1), but would like to know a better way.

I am having a real hard time with the geocoder API of android sdk 1.5rc2. In my app I am trying to get the addresses corresponding to a location name by using the getFromLocationName method of the Geocoder class. But the problem is whenever I call this method it returns a null value. I have also pushed a geodb file containing some fake addresses at 'data/misc/location' directory in the phone.
The format of the data in the geodb file is as follows :
address 1 latitude "38.898763" longitude "-77.036655" line 0 "1600 Pennsylvania Ave NW" line 1 "Washington, DC 20006" locality "Washington" region "DC" postalCode "20006" countryCode "US" countryName "United States"
and following is the code snippet : Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses=geocoder.getFromLocationName("1600 Pennsylvania", 10);

Following other threads - I'm trying to get a unique device ID from the device. I tried this:
String ID = Settings.Secure.getString(context.getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);
but this returns null when running on my G1. Is it supposed to be returning a valid number, or am I accessing it wrong? I don't want to use the telephony device ID because that requires more permissions.
