How to draw the curve using Android APIs?
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?

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.

I have spent the last couple of days trying Phys2D and JBox2D, however both perform very poorly - I am struggling to get even a few objects to simulate smoothly as frequent garbage collection spoils it. One question I do have is will these run smoother on an actual G1 device or is the performance of the emulator accurate?
View 1 Replies View RelatedI've been block by this question for about a week. I tried to implement a simple application: show a image, when user touch on screen, I want to create a GLSurfaceView to cover the previous image. Then show some 3D effects on this GLSurfaceView.
The logic is quite simple. But I have a serious problem. When GLSurfaceView comes out, the whole screen become black, after 1-2 seconds, the GLSurfaceView with texture shows up. Is there any way to make this smoothly? The 1-2 second black screen is really a bad user experience.
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)?

View 1 Replies View RelatedJust curious what you guys normally have freed up on your phones, since this is normally a way of speeding things up a bit. I've been reading today about how Task Killers are somewhat counter-intuitive and do not help with battery life. So I deleted and I'm now thinking about not having enough free memory... Figures.
Anyways, I'm 25mb right now, and I've hovered between there and about 125mb today. I'm curious what you guys are normally seeing. If I'm not using a task killer, is there something else you might recommend to keep things running smoothly?
