I am currently using Big Five to indicate the phone's current location
on Google Maps (the app will obviously eventually do a lot more than
just this!!). Big Five seems to only return the position as
triangulated from cell towers, never the GPS position. I can open up
the iPhone Google Maps application, and it will return my current
location to within a few metres. When I request the location from Big
Five, I always get the same location and it appears to coincide with
the general location reported by the Google Maps application before it
acquires a GPS fix.

I am calling the getCurrentPosition() method and it successfully
calls back with a position - the problem is that it is always the same
position unless I move about a kilometer or more and get a different
cell tower triangulation.

Any ideas as to why I am not getting a GPS position in Big Five, even
though my phone clearly is?

Thanks

I was trying out the Demo App today and it has the same problem. It
will not give me a GPS location, only a cell tower fix.

The location manager in Big5 uses the default accuracy, which is Best Accuracy. It should get you the best possible location in your current location. The weird part is that Google Maps is getting it so it can't be a bad location.

I've just updated LiquidGear, adding the option of accuracy to the location. The JS gives an example of using a default of 3 meters but you can specify anything from 1-100 meters.

I tried to use the deprecated functions Device.Location.wait() and
Device.Location.last() with the same result. I do not get a GPS
location while the Google Maps application does. Can anyone else
confirm this behaviour (or not, in which case it might be my phone
that is the problem)? If so, it should be reported as a bug. I was
relying on Big5 for an application that needs to be working by the
beginning of May and this problem is a bit of a show stopper.

Is LiquidGear likely to be available for download from the app store
any time soon? The whole point of these apps is to provide a platform
for strictly web-based solutions that can be downloaded readily by
anyone. If I have to build my own custom version of Big5 or
LiquidGear, then I might as well just use PhoneGap and post my own app
to the app store.

LiquidGear is used just like Big5 and PhoneGap. You simply add in your HTML/JS files and you are good to go on submitting your app. You would also need to change the name to your own app name and the icon as well so there are no traces of LiquidGear to the user in the end result. Compile in XCode and you are done. You can download the LG source files from Google Code for free now at:

I would recommend checking out and updating the SVN source since it is constantly being updated with new features. The zip download is updated with every stable release about every week. The new iPhone framework was zipped this morning.

Hi,

indeed Big5 is not very precise by getting the current location. This is
on the plans to get changes in future, Giraldos approach in LiquidGear
is the best right now. So if you use source code version and not the one
in the AppStore you should consider using that or PhoneGap for the moment.

Hi

When Apple releases OS 3.0, will the changes in the WebKit be
available to Big5? If so, then it sounds like the best solution for
this problem is to wait for OS 3.0.

I strongly believe they will. Anyways there will be a new release of
Big5 for iPhone OS 3.0 and I'll then check or implement the feature.
