[android-developers] Re: Google Maps API hidden maps and opengl
There's an opensource port of Android on GitHub which includes a (slightly dated) implementation of the Google maps API. It supports OpenStreetMap and a couple of other map sources. I managed to adapt it to support Bing maps.

It's supposed to be in a MapActivity, but I figured since Google uses maps in a live wallpaper I could use it as well, although I know this is not always the case. I've learnt the hard way that just because Google does something with android doesn't mean they expose those methods to the developers.

[android-developers] Re: Device's User-Agent from Application
Although systems like WURFL use the user agent to identify mobile devices and their capabilities, it's actually an identifier of the browser, not the device. Your PC may be a Mac, or a Windows box running on an AMD, Intel 486 or i7 - the user agent isn't going to reveal a lot about this - perhaps the OS and a rough indicator of the age of the PC. It will tell you whether it's IE, Firefox, Chrome etc. If you're writing your own HTTP client then it's up to you to create your own user agent to provide your server with any application- specific it needs (Android/iPhone, version number...). You might want to add some of the fields from http://developer.android.com/reference/android/os/Build.html. Screen size is something you can also code into your user agent. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How to warn user when back button is pressed to navigate out of my application?
My first thought was to suggest that you rethink if you really need to do this - maybe your app isn't going to be as important to your users as you may think. But then, I been frustrated in the past by games which exit in the middle of the game if you press too far right... Maybe you should provide an option (which you'd only ever ask once): Always confirm before exiting I can find some posts on how to warn user when the back button is pressed to 'quit' the application. The common answer is to catch the key down event by onKeyDown, or use startActivityForResult(). My approach is to restart the activity in onStop(). Is it a better choice?

[android-developers] Re: XmlPullParserException: expected: START_TAG
If you determine that the problem is that the XML (or HTML!) is badly
formatted and you have no control over it, you can do something like:
int n;
while( (n = xpp.getNext()) != END_DOCUMENT ) {
try {
// do your parsing element-by-element
} catch( org.xmlpull.v1.XmlPullParserException e ) {} // ignore the
exception
} catch( Throwable e ) {
log.warning(error while parsing file: + e.getMessage(); //
you may want to catch any other exceptions and do something about them
}
}
It might not be the most efficient practice to perform the try/catch
within the loop, but if somebody else is sending you dodgy XML there
might not be anything you can do.

What I want to do is query markers from an online database as the user pans around (in the same way the actual map tiles are fetched). Is there a simple way to do this? As far as I can tell I need to subclass Overlay and implement the draw method, but where is the best place to put the code that fetches new markers when the map is panned?

[android-developers] Re: ADC 2 rating
Unfortunately, I seem to have made a fatal mistake of placing a mandatory user registration form as one of the first Activities. I only had 50 people actually register (some with fake email addresses which I'm actually okay with, given the circumstances), and out of those only 3 or 4 people actually spent longer than a couple of seconds looking at the application. Only by the 5th Activity does my application get really interesting (an editable map overlay which can snap to predefined points) but only those 3 or 4 judges would have even seen that. I'm very disappointed - how can 96 people claim to have judged my application if they haven't even interacted with it? About 140 users for ours. I agree it's a pretty small sample, not sure why they couldn't have left the first round open for a while longer. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

36 visits (80 hits) for page 1's audio.

[android-developers] Re: MapView with itemizedOverlay still don't work
You need to call:
mapOverlays.add( itemizedOverlay );
also, if you're adding/removing overlay items to/from ItemizedOverlay,
you may need to call setLastFocusedIndex(-1) (or whatever the method
is). I think in your case you won't need to worry with this as you
only call addOverlay and populate once.

ignore navigating from one to the other by up/down key presses)

one is right at the top of the screen.
