I need to draw a line, from one point to other...
I found one link (http://csie-tw.blogspot.com/2009/06/android-driving- direction-route-path.html) about this, but itīs not works well.
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? ...

View 6 Replies View RelatedI 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:...................
In my android application I use this method in "draw" Overlay class for draw route on map. Can someone tell me if this method is good (in terms of performance) for route draw on map or I must to put code in Thread ??
I'm new to android.
public synchronized void draw(Canvas canvas, MapView mapView, boolean shadow) {
if (pointsAndTimes.isEmpty()) {
return;
}
Projection projection = mapView.getProjection();
Paint paint = new Paint();
paint.setARGB(250, 255, 0, 0);.............
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.
View 3 Replies View RelatedI 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?

View 8 Replies View RelatedThe 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.
View 4 Replies View RelatedI started this thread because i think i'm amongst the majority here so maybe we can get some specific responses.Here's what i'm looking for
- Form Fitting so as not to add bulk, but thick enough to provide some protection in case it's dropped. Also thin enough so that it will fit in any desktop charger/cradle that comes out.
- No high ridges (Especially on front like on the Body Glove) so that it doesnt block access to Optical Joystick, Volume Rocker, Power Button and USB Port.
- One piece - So if/when it's dropped the phone doesnt explode into a yard sale and it stays protected.
- Protection for Camera (Flush)
- Carry over styling on stock back cover (doesnt matter to me but may to some)
- Material - enough grip so that it wont slip out of your hand or off your shoulder but not too much so that you can't get it out/into your jeans.
- Color selection (but black is fine)
Please post your camera setting for the evo and why you use it so we can get the Perfect Camera settings.My pictures seem to be a bit bland and dark so I increased brightness and saturation. Pictures tend to be a bit too sharp so I lowered it and iso just seems to make my pictures clearer. I dont know much about iso
View 22 Replies View RelatedI 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)?
My wife and I got our Incredible yesterday and applied the Phantom Skinz...However, there are fingerprints on the sticky side of the protector that are now very visible. We made sure our hands were clean, and kept our fingers wet while applying...Anyone offer any advice or tricks to get this perfect?

View 2 Replies View RelatedIm wondering now if the GPS problem is really a problem with the way the individual phone is "tuned" at the factory, Its not the software thats for sure. I'm sure I have the same software as everyone else and my other 4 handsets had. I noticed that all 4 prior phones had a varying degree of GPS accuracy. This one #5 is spot on and quick to "fix" in my locations. I have a large home and tested the handset in my house last night and watched it track me through the rooms with spot on accuracy without fail. So I say why is this phone different? It has to be the way its tuned at the factory, if you notice when you take the battery door off there are a bunch of little holes around the battery compartment these are manual tuning pots for various phone functions and I'm guessing one is for the GPS. If my handset is accurate there is no other reason besides bad final tuning of the GPS system causing another handset to be inaccurate. Now if my bottom 4 keys were only as sensitive as my GPS I would be totally happy with my Epic.
