Android : How To Compute Zoom Level Against Returned Markers?
Aug 5, 2009
I'd like to know if there is already a way to know from a given set of markers, the zoom I should apply to the map or do I have to do it my self? (this depends on the resolution so i expected to find it in MapView because it knows its boundaries.

I have done my fair share of google searches for this and have come up empty.
I have a set of marker(25) that are being displayed on a MapView. I would love to be able to have it zoom to a reasonable level to make the markers readable.

I have lot of markers on my map. Zooming in each marker shows me a position. but zooming out the markers are overlapping each other and it is more difficult do determine the position of a marker.
Is there a way to scale the marker image depending on the zoom factor?

Is there a way i can set a minimum zoon level for my MapView?. I don't know if you've realized the map looks really ugly when zoom level is one. You see the whole world map replicated. I would like to avoid that zoom level no matter if user is zooming in through gestures or zoom controls. I've looked at different alternatives, but none seems to work. Does somebody have a good idea about this?

I'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.
09-04 04:24:21.485: E/AndroidRuntime(6834): Uncaught handler: thread main exiting due to uncaught exception
09-04 04:24:21.510: E/AndroidRuntime(6834): java.lang.VerifyError: [code]....
There seems to be a problem with an uncaught exception and reflection, although....why does it work on API level 10?

The View class has a compute Scroll method whose documentation states: Called by a parent to request that a child update its values for mScrollX and mScrollY if necessary. This will typically be done if the child is animating a scroll using a Scroller object. See
http://developer.android.com/reference/android/view/View.html#compute...
I am using the 1.5 SDK and I do not have access from within my application to the mScrollX and mScrollY protected member variables of the View class. However, I must have a custom scroller object for my view.

I have a MapView that I'm displaying a "useful radius" (think accuracy of coordinate) in. Using MapView's Projection's metersToEquatorPixels, which is admittedly just for equatorial distance) isn't giving me an accurate enough distance (in pixels). How would you compute this if you wanted to display a circle around your coordinate, given radius?

I'm wondering if it is possible to move markers when using a MapView. I use a fullscreen MapView which has a few (not more than 5) markers which I would like to move and update by just moving the markers to a new position.

On my app I will be reading in from an XML file thats formatted something like this
<database> <db1>
<db> <name>name here</name> <street>street here</street> <long> longitude here</long> <lat> latitude here </lat> </db>
<db> <name> new name here </name> <street> new street here </street> <long> new longitude here </long> <lat> new latitude here </latitude> </db>
</db1> </database>
With this information I need to create Overlay Markers on the map (using latitude and longitude) and when they're clicked on I need it to display the name with the address. Depending on the conditions of where the map is, the number of markers will be different so I need a dynamic model for reading in these markers.
If I were to use Document methods like getElementById(String name) then I couldn't call getElementById("name") because it would likely try to call just the first <name></name> or give an unintended result.

Using Google Maps on Android does anyone have any ideas on how to load only markers that would be displayed on the current screen? I'm thinking about sending a request to a web service that returns the lat/lng for the relevant markers. But what would the parameters be that I could use to calculate if a given lat/lng is within the screen?

I'm scaling markers on a MapView with the following code
CODE:.........
And:
CODE:.............
Which works, but the shadow below the marker has wrong offset when scaled. Also; i override the public boolean onTap(int index) in ItemizedOverlay to detect taps on the markers, but it seems inaccurate. I can click some range outside the marker and still trigger onTap...

I have a .Net Web Service which returns a single integer value. When i call upon it from my application, no value is returned. Nothing at all really happens. I set up breakpoints and watched it's progress and it seems the problem is coming from when i get to this line:androidHttpTransport.call(SOAP_ACTION, envelope);
I have a hunch that my URL string is the problem. I've tried replacing the "localhost" in my URL string with my local and network ip with no luck. Whenever i replace the localhost with the ip in my browser i get Server Cannot Access or Unable to Connect pages. Does anyone know a solution to this problem?

I know how to get the calculated GPS position via getLastKnownLocation (). As tests show, this function really always returns the last known location, so it doesn't matter if there is a gps fix available.
How can i check if the returned location is reliable? I tried it with getAccurracy(), but this function even returns a accurracy although no gps fix is availavle (anymore). Is there a possibility to get gps dop values? Used SDK is 1.6.

I want to grab this Response from the HttpReponse and print it out. How do I do this?
I tried response.getEntity().toString() but it just seems to print out the address in memory.
