Android :: Location DistanceTo Uses Error Parameter In Approximate Distance Calculation?
Jun 27, 2010
I am wondering if the Location.distanceTo method will use the accuracy field of the Location object when approximates the location, or do I have to add by my own the errors to these fields. The usage is to compare the distance against a proximity value.
Float dist=currentLocation.distanceTo(loc2); Would this be if (dist<100meters) or
if (dist+currentLocation.getAccuracy()+loc2.getAccuracy()<100meters)

I am implementing an application to search for nearest local venues from a gps coordinates database.
I am using the Location class distanceTo() function to calculate distance between two location the current one and the one from the database.
CODE:............
This work fine and i am able to use this distance to calculate proximity in the rest of my app, but the distance it self is not apparently in meters i am getting result like 4134801.4 i am sure that the distance is 3200meters in this case.

I know that it's mostly "approximate". But, I must know the EXACT location of the phone, regardless of battery life or whatever.I need the exact location of the phone! Is it possible?

1) I have not been able to find out in which units Location.distance Between receives the latitude and longitude. Is it degrees or micro degrees? Whats the unit for the distance returned? 2) In windows XP using Eclipse 3.3.2. Emulator does not send coordinates properly. Either it by hand or by loading a gpx file the location Listener is not invoked. This same code I have tried it in Ubuntu and works fine. Does someone know how can I solve this? In the office there is no linux installed and I can take my personal laptop.

I can easily find long/lat of my current location. Once I do that, I would like to find long/lat information for locations at distance X from y current location. Does anyone have suggestion(s) on how to do this using Android SDK methods?

My dad has to measure a lot of acreage and area around fields. Anyone know of an app that you can use the DROID gps to do this? Such as start at a corner of a field, hit start and drive around the field and then measure it from the gps?

I am trying to make an app for the Android that does RMD calculations. The program, however, keeps giving 0.0.
I think that my problem lies in this code:
CODE:......................
I tried using .equals(), but it complained that I was trying to dereference the long value. Also, I am aware that java.util.Date is deprecated, but I don't want to try the other classes. From my first Android app, I figured out the "==" does not work, but I am not sure what to do here.
I have verified that the input for a balance and the birthdate values were accepted, so that is how I limited it to this particular class.

I am getting an error in my Problems tab for my Android Project in Eclipse. The error is "Android Packaging Problem" with an Unknown location. Unknown Error NullPointerException
I cannot determine what this problem is. My project was working a few hours ago. The only change I made was to add a public interface ITrackDao to my project and implement it. There are no errors associated with this. I am not even sure where to begin to look. I cannot launch the application.

We see the bigger font for Agree and disagree buttons for the Alert dialog when the network provider is selected in the location settings menu. Any pointers or suggestions which part of the framework code need to take a look. This dialog is controlled by Networklocation.apk which is not open source.

I have a simple spinner which has several number options. I want to just select a number and then it does some math to that number and outputs it in a text box. For some reason it's only doing math on the 1st entry in the list and if you change it doesn't update.
Code:
package placeorder.com;
import java.util.Random;
import android.app.Activity;[code].....

I've noticed that the graph my S4 GT-19500 displays to show internal storage used is wrong. I have a 32GB SD card and I move most of the apps across to save space but the S4 doesn't seem to recognise this when it shows internal storage used.
This is my internal storage screen displayed from Settings->More...->Storage
This is what my applications are using displayed from Settings->More...->Storage->Applications
If I add up all the values it comes to around 1GB nothing like the 3GB claimed!
Also if I copy the ENTIRE file system to windows and look at the size of the directory + sub-directories the value is 3.92GB nothing like the 8.92GB that settings claims is there. What is happening here?

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.

I am trying to use gwt-mobile-webkit, particularly its location api. It works well with iPhone (both device and simulator) and Firefox and on G1 with 1.6 Android, however, it does not work on G2 with Android 1.5 on it. In result I am getting onFailure callback with Permission Denied error.
So it seems, that there is some geolocation API (gears or HTML5) in the browser available, but it just does not want to ask user for granting permissions. Do you know if there is any workaround or just enable it somewhere in settings?

With the stock Touchwiz software you can not access the normal Android Settings menu for Location and by default the "Network Location" function is disabled.I installed Open Home (which is a must for this phone imho) and now I can access the classic settings menu.I enabled Network Location then launched Google Maps. After a second or two it centered on a road in Bellevue, WA that is not too far from T-Mo headquarters, problem is I am on the East Coast of the US. I pulled the battery and reboot the phone.Upon reboot I opened Google Maps again and it quickly found my approx location correctly but then within a second or two it switched back to this phantom location in Washington state.Has anyone else experiences this? If so is this a glitch with my phone or a known issue with the TouchWiz/Android OS? I really need this functionality in order for the phone to be useful for me. Anyone know of a fix for this?

I am having trouble with Google Maps in my HTC Desire. When I look at My Location, it is completely wrong. When I rotate my phone, the arrow turns round, but the location is nowhere near where I actually am. Anybody have any idea what I can do about this, as I really need to use this feature.

I want to make a apps that check what's the nearest place from where the user is. I can easily get the location of the user and I have a list of places with latitude and longitude. What would be the best way to know the nearest place of the list against the current position. I could not find anything in the google APIs. I am worried I need to resort to my calculate and have to do math to calculate it.

I have used the algorithm on http://www.movable-type.co.uk/scripts/latlong.html to find the distance between two points.
My two points are
long1 = 51.507467;
lat1 = -0.08776;
long2 = 51.508736;
lat2 = -0.08612;
According to Movable Type Script the answer is 0.1812km
My application gives the result (d) as 0.230km code...
