Android : SQlite Getting Nearest Locations With Latitude - Longitude

Sep 12, 2010

I don't know if I'm wierd, but I haven't found any topic about the subject. The thing is, I have data with lat and lng stored in my SQLite database, and I want to get the nearest locations to the parameters I put in (ex. my current location - lat, lng).I know that this is possible in MySql, and I've done quite some research that SQLite needs a custom external function for the Haversine formula (calculating distance on a sphere), but I haven't found nothing yet, that is written in Java and is functioning.Also, if I want to add custom functions, I need the org.sqlite .jar (for org.sqlite.Function) and that adds unnecessary size to the app.The other side of this is - i need the Order by function from sql, because displaying the distance alone isn't that much of a problem - I already did it in my custom SimpleCursorAdapter, but I can't sort the data, because i don't have the distance column in my DB. That would mean updating the DB everytime the location changes and that's a waste of battery and performance. So if someone has any idea on sorting the cursor with a column that's not in the database, I'd be grateful too!I know there are tons of Android apps out there that use this function, but can someone please explain the magic.

Android : Displaying Longitude - Latitude Values Stored In A SQLite

Apr 2, 2010

I am currently in the process of creating an application that records current location of a mobile device in intervals, displaying the route as a coloured line on the device in real-time. At the same time the application is storing the longitude and latitude in a SQLite database as I want the user to be able to bring up that specific route again.The route has a primary key and each waypoint is linked to that route by a foreign key. What would be the easiest way to display the saved route on the map?

Android :: Latitude And Longitude From Texts

Nov 20, 2010

I get Longitude & Latitude coordinates texted to me where I then have to copy & paste it into Maps to get the location of the tracker.

Would anybody know of an app that can reveal its location by just clicking on the text, or if there's a faster way to enter it into Maps?

Copying and pasting specific parts of text is kind of finicky.

I'm trying to retrieve Latitude/Longitude informations of an image, but I always get 0.0 for lat/lon. But I know the image has this information inside, because I tried it with exiftools. When I use exiftools I can see the lat/lon values.

My Source: startActivity:

Android : Cannot Retrieve Latitude / Longitude Without Internet Connection

May 12, 2009

I am having problem in getting the latitude and longitude on my phone.. So i create an application that only display the "Toast" once i request it to. using the LocationManager.NETWORK_PROVIDER, instead of gps. And I try it on my G1.. I found out that if the G1 is connected to my WiFi, i can get the coordinate of my position, without any problem.. once i turn off the WiFi of the phone. The onLocationChanged() is not triggered anymore, instead, onStatusChanged() is triggered.. And I get TEMPORARILY_UNAVAILABLE error.. So what i want to ask is :Is internet connection required to retrieve the coordinate ONLY?
