How can I implement algorithms such as Dijkstra or backtracking on Google Maps integrated in Android ? For example I want to compute a route from city A to city B such that I pay the lowest price for gas.

i've read about phonegap which enables to write web-based apps for android and i was wondering:how is performance of phonegap compared to a "real" android app.what would NOT work in phonegap?i know it's possible to implement google maps with phonegap but i guess there's a lots of limitation compared to direct coding the maps under android?as a newbie to android (but intermediate in web-programming), should i rather go for direct android coding instead of phonegap? i'm planning to write an app which uses google maps service+gps, database access and such, and i'm afraid it's not really possible with phonegap.
View 2 Replies View RelatedI have a couple of images on available to my program. They are parts of jigsaw puzzle (with rectangular pieces though). I wanted the look and feel similar to that of google maps in android.
One way I could implement was to create a set of ImageViews and keep recycling them, as the user pans the image in any direction. However, to me that appears like a brute force method. Is there any alternative approach to implement such kind of application? Or rather how is google maps implemented? A set of Imageviews ?
I would like to create a search in my app which acts like the map search in the Google Maps app. I have creates an an auto complete text view which updates dynamically based on the results of the Geocoder.GetLocationByName() Method. However the results retrieved from this function are really bad and not at all consistent with the text I pass to it. Is there a better method of doing this to achieve accurate results?

View 4 Replies View RelatedI am developing a mobile application that involves complex image processing operations. The app is designed in Java while the core image processing ops are implemented in native code, and compiled using the Android NDK.Now, I know that native code will *not* yield any significant performance improvement over Java code, and that the NDK purpose is only to support re-use of code libs (or to quickly integrate legacy code).are there any resources/tips-n-tricks/white papers/ samples on optimizing image processing algorithms for Android? To be even more specific, I am looking out for optimizing memory operations (cache misses, memory stalls, etc.). I profiled my application code and came to the conclusion that memory issues are causing the *maximum* performance penalty. (Nothing surprising over there, it is expected, but just verified with profile data as well).
View 1 Replies View RelatedIn Android, I could see 2 BitBlit functions defined in skia and libpixelflinger libraries.
1) S32A_D565_Opaque function in external/skia/src/core/ SkBlitRow_D16.cpp has one implementation
2) scanline_t32cbl6blend function in system/core/libpixelflinger/ scanline.cpp has another implementation
Both implementations look different. Please help me understand the rationale behind these algorithms and the reason for having two different implementations/algorithms.
Is Google Latitude available in the UK or not, because it doesn't seem to be working for me? I have received the RC9 update for G1 and have Google Maps 3.0. Is there an a Google Latitude application that I should have or do I access everything through Google Maps? When I go the www.google.com/latitude on my G1, it offers me the option of "launching" Latitude but it just takes me to Google Maps. From there, I cannot see the locations of my Google "friends" (who have agreed to show location), neither does my own location show up on the Latitude homepage on the web (I have settings turned to "detect my location automatically").

View 2 Replies View RelatedI know with Android 2.x there is the ability to tap into Microsoft Exchange, for at least email, if not calendar and contacts. I would like to see how this was accomplished. Particularly because Microsoft Exchange exposes SOAP web services, and I understand there is no native Android support for SOAP. Since this is open source, shouldn't I be able to find something in the Android source? If so, can you point me in the right direction of where to find it in the ~4Gig (!) source? I want to develop an application that accesses Exchange contacts and calendars, but don't want to reinvent that piece.

I'm using the latest version of Google Maps on JB 4.2.2 [Nexus 4]..I noticed that I cannot edit the names of my locations in "My Places" in the phone app. So I used Google Bookmarks (google.com/bookmarks) from my PC to edit/rename My Places. However, the names do not sync or carry through to the Google Maps app on the phone. The names in the app are still the generic names, coordinates or street names.
Is there any way to change the names of My Places and get them to sync with the phone app? Really baffling!

View 3 Replies View RelatedI have several Android devices and each of them has different version of Google Maps: 3.0 in HTC G1, 3.1.1 in HTC Dream and 3.4 in Nexus one and Motorola Droid. When i use the following code: Intent myIntent = new Intent(Intent.ACTION_VIEW,Uri.parse("geo:0,0? q=Starbucks"); I get different behavior on the devices: On the latest versions of Google Maps application I see a map the term centered around my current location with a reasonable zoom radius while in Google Maps 3.0 I see list of results and button to the map. Is there a way to get the same behavior on all devices? of course i prefer the behavior of the latest versions

View 1 Replies View RelatedCan somebody please explain this to me. I have been looking through a number of forums relating to Android with maps (google). It costs money to use maps with tmobile as a data connection is required. That's fair enough. But some people say GPS is free (albeit heavy on the phone battery). What use is GPS without some form of maps?

View 2 Replies View RelatedGoogle maps api is great for developing location based services for mobile phones. But for some reason the use of it is restricted for me in a special project.E.g. if your project is in conflict with the general terms and conditions of google it is not recommended to use google maps API.In my app (android, iOS) i want to display a location on a map by retrieving gps information. Overall the api should offer a similar scope of operation like google maps API.Which alternatives do you know? Maybe there are open source api's?

View 3 Replies View RelatedI'd like to show you off-road GPS navigator utility, created for active people. I like no-map Garmin GPS handy navigators, so I created software, that has most functions of such navigator. TripComputer records tracks of your trips and stores your interesting waypoints. You can view them on map view, see stats like distances, speed, time, altitute graph, bearing, azimuth, and many more. Also, if you have internet connection, you can send your selected waypoints and find waypoints sent by others,to use in you own trips.
At this time, TripComputer does not use maps - because in off-road areas, maps are useless. However, topo maps will be supported in future versions. Also, I'm working on GPX files and some geocaching support.
