Android :: Fastest Way To Draw A Lot Of Points In OpenGL ES?

Dec 26, 2009

I'm making a game for android where I need to draw a lot of points that change position every frame. I use the ndk to get faster processing performance of the math/physics section of the game, so I need to use OpenGL to get the fastest performance. Right now, I make a texture every frame out of an array that holds the colors of every pixel. I am only able to get ~10 frames per second with this method. Is there anyway I could speed this up? ...

Android :: Draw Path On MapView From Large Amount Of Longitude/latitude Points

Aug 2, 2010

I am writing a application that needs to draw a "route" comprised of lots of GPS points (long+lat). The points are close together and don't follow roads, simply drawing a line between each point is ideal.

The current implementation I have is very slow as I am looping over all the GPS coordinates and creating a new Point and overlayitem in an itemized overlay. This takes around 20 seconds for it to load all of these points and draw them to the mapview. Is there a way in which I can construct a series of lines or point from the GPS coordinates and draw them onto the mapview?

Example of current implementation:

CODE:...................

Android :: What's Learning Curve For Phone?

Jul 22, 2010

What has people's experience been in learning Android? I'd be interested in how long it takes to get to the point where you're writing your first app, and how the experience compares to learning some other programming API. I know several professional programmers who have tried to learn Android and failed. Is it inherently more difficult or larger than you might expect? But there's a survey here http://www.infoq.com/news/2010/07/Mobile-Survey that claims Android has the shortest learning curve of all smartphone platforms. I wonder how the survey guys could have got such a perverse and unlikely result. I have my own views and observations on this, which I'll mention as a dialog develops. I don't want to bias the discussion with my perspective at this point.

Android :: Align Image Buttons On A Curve Programatically?

Oct 6, 2010

I have a series of buttons on a main menu. Instead of the standard side by side, or one on top of the other, I'd like them to be aligned around a semi-circle. Since I can't drag and drop the buttons to the place I'd like to in the designer, I was wondering the best way to do this? Can I do it in the XML, or would it be best to do it programatically?

Motorola Droid :: Way To Switch From Curve To Phone?

Nov 12, 2009

The droid looks like a great fun device, but I use my mobile device to help me be productive in a sales position. I have some issues keeping me from pulling trigger on a droid. I use mobile device mainly for work related tasks (phone, email, calendar, etc). Any comments would be greatly appreciated. If anyone else has moved from BB to Droid and has other things they miss (besides BBM) please respond.- Lack of email search for exchange email. Almost an instant deal breaker. Is this in the works to be fixed? - Ability to operate with one hand (phone, email, etc). Very easy to dial a contact from BB home screen simply by typing their name. - Speed of typing. I send emails from my BB even when sitting in front of computer. The BB is very easy to use and type on. - Look up internal users on BES. Great for getting contact info of person at company that I don't have in my address book.

Motorola Droid : Looking To Replace BB Curve / X Vs Fascinate For Streaming?

Sep 26, 2010

I am looking to replace my BB curve soon and have been debating for weeks on the Incredible, Droid X, and now the Fascinate. One concern of mine is the ability to stream live video (flash) from sites like atdhe.

I watch a lot of hockey and the ability to stream from a site like that would be excellent. I have been hearing mixed stuff about the video quality streaming wise from the X, and I know the Fascinate has the better GPU, so do you think that would make it the better option for streaming flash video (when it gets 2.2)?

Android :: Catching Points With GPS - Geo Fix

May 5, 2009

I am trying to write a code about catch lat. and long. points with the GPS, actually I am using the shell with the commands "geo fix" because the DDMS doesn't work in linux apparently, I am using this scripts:

getBestProvider(criteria, true); getLastKnownLocation(provider); requestLocationUpdates(provider, 2000, 10, locationListener);

The questions is: the program is working right now in the emulator, but what about if I move the program to the real cellphone? Is the same? I need think in something else?

I am just a beginner in the Android and was experimenting with HTTP.I have published the result of my experimentation through the following link http://kausikdas.webs.com/apps/blog/show/1489440-http-in-android. I am yet to get a device but working with the Simulator.I need feedbacks on the possible network problems I should handle. e.g.: 1. Do I need to discover the access points and dial one before connecting? 2. How can I know which services (Data/Data & Voice/Voice/No/Emergency etc.) current network is supporting? 3. Anything more to take care of?

Android :: Adding Labels To Points On Map?

Jan 6, 2010

I'm trying to add a label to each of the points on a map that I've created. Setting the "title" and "snippet" values of the OverlayItem don't seem to automatically cause these labels to appear however. I would've thought this would be a pretty simple and common requirement. Am I missing something? Can someone tell me if there's a function that does this?

Android :: Displaying Route Between Two Points On Map

Dec 6, 2009

I'm trying to develop an application which display the locations of contacts on a map (a Msn-like but for geo-localisation). I search to display a route between my own location and a contact location I want to join but I find yet no solution to do this. In the Android API and Maps add-on API I just find classes to display and listen Location, Distance, GeoPoint, etc., but no possibility to display a route between two points. Is it possible or not provided by the API?

Android : Physical Size Of Font In Points

Aug 3, 2010

I have two devices - HTC Tattoo and Sony Ericsson Xperia X10. One has 145 DPI, the other 245 DPI.

When I specify font size for a TextView in points, like this:

CODE:...................

I get different physical size of text on these two devices. On 245 DPI, the text is barely readable.

Now, "pt" size is supposed to be physical. I.e., in my test, both text blocks should have letters of the same physical height. Which is not the case.
