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);.............
I tried E-mailing the staff of Phandroid about this, and didn't get a response about posting it on the site. However, I thought that it may be of interest to Android fans/developers looking for some viable statistics. The sales data are estimates, and we'd like feedback from developers on accuracy via our methodology.If you do have an app on the Android market place, we'd love to see how your stats compare to what we have in our data base - from what we've seen, most of our stats are within +/- 10% of actuals, but we're always looking for feedback!

Commencing with the TrackID Charts API, the program will extend to cover more innovations and content including the recently announced Creations service.
We have created a developer portal for the OpenAPI program at api.developer.sonyericsson.com. The portal provides a rich set of services for developers, including documentation, case studies, and reports on how SEMC APIs are being used in developers' applications.
To use our OpenAPIs, including the TrackID Charts API, simply:
1. Go to api.developer.sonyericsson.com and register
2. Get the API documentation you need right there on the portal
3. Follow the procedure to get up and running

View 3 Replies View RelatedI'm trying to figure out how to draw on a bitmap in android, and keep a copy of these changed bitmaps for an undo function.
Bitmap b = ...
Paint p = new Paint();
canvas.drawBitmap(b, new Matrix(), null);
canvas.drawCircle(0,0,20,20);
//does Bitmap b have the circle drawn on it next time?
Or how do I get the bitmap after its been drawn on with the canvas(I want to preserve a stack of bitmaps with the changes applied by canvas drawing)? Maybe I'm going about this entirely wrong.
I'm new to openGL and I have done some first tests with drawing a triangle. Now I would like to draw a circle, which is filled with a texture, but I have no idea, how to do so.Can someone of you give me a hint?
View 5 Replies View RelatedI'm investigating the possiblity of writing an app for Android/iOS4/both that would use GPS in the background. I found the "Receiving Location Events in the Background" section of the iphone developer documentation, which recommends that I only register for "significant location change" events. I'm not aware of any such capability in the Android SDK, but it still seems like a good idea to do it this way if I can (so as not to drain the battery). My question is this: has anyone done any sort of benchmarking for this on and iPhone/Android phone? So far, I've seen a lot posts/documentation saying that listening for GPS events in the background is a VERY BAD THING and I should AVOID IT AT ALL COSTS, but I haven't been able to find any numbers for just how much power a background application listening on GPS changes would drain (i.e. % battery drain per time app is running in the background).
This information might be helpful for me (and possibly others too) because I might be able to poll less frequently or even register/unregister my GPS listener based on power drain. Essentially, I could try to put a ceiling on how much battery life my app could drain while in the background.

View 1 Replies View RelatedI'm making an App that needs to be able to draw new graphics on top of the last set.
This is my current onDraw() method -
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.WHITE);
if(points.size() > 0) {
//do some stuff here - this is all working ok
canvas.drawLine(p1.x, p1.y, p2.x, p2.y, linePaint);
}
}
Basically, I need to draw the new graphics as a layer on top of the last, so what I'm looking for is a way to carry the image of the last canvas to the current. I have tried to figure it out myself using the canvas.setBitmap() method but it acts very funny.
I have some images that I want to put on top of each other on random order. If it possible using one ImageView or do I need to create multiple image views based on number of images?
View 2 Replies View RelatedI studied the Androidreference for hours now, but don't really get the clue how to draw something (Text, Bitmap, Path ....) on a ImageView.
Should I extend View and use the onDraw()-Method? If yes, how can I draw on my ImageView?
Or is there any other way to achieve my goal?
I have a set of views that are populated with data from an online database. The context menu has a "refresh" choice that re-reads the online database and updates some attributes of the views, like setText and setChecked for some buttons. After the various setTexts and such, I invalidate the Views. However, they are not immediately redrawn. In fact, they don't get redrawn at all unless something like a rotation happens to cause a redraw of the screen. How can I initiate an immediate redraw after the refresh is complete?

What I want to do now is be able to draw various sparks, flying cows etc. at arbitrary places on the screen on top of the whole thing. What's the best way to do this? Should I override onDraw() on the containing View and draw after calling super.onDraw()? Or is there some better way of drawing a layer on top?
View 1 Replies View RelatedI am wondering what the best way to render a tournament draw (scrollable) might be for android. Since I am new to this, I was not sure whether to invest time creating a ListView sort of thing or dynamically building html pages and rendering them with WebView. Or I could plop everything into a regular scrollable text view, perhaps. The main requirement is that I would need the tournament participants to be individually clickable.

View 2 Replies View RelatedI'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here.
View 1 Replies View RelatedI am creating a android app using LunarLander as a example.Now I need to create a few buttons which are drawn over the view.I do not want them as a seperate layout above or below the view but in the custom view.Is this possible or am I going to have to programmatically show the button images then detect the touch. The buttons I create using new never show on the app. I assume this is because I have overwritten the onDraw and the buttons are never drawn even though I call.

View 4 Replies View RelatedI have an application that uses GLSurfaceView to draw OpenGL ES graphics. This is all working (mostly) how I would expect.
Now, I would like to implement a screenshot feature. For normal views, it seems that the standard practice is to create a new Canvas with a Bitmap and then draw to that Canvas using View.onDraw(Canvas).
I've tried using SurfaceView.draw(Canvas) in a similar fashion, but it always results in a blank (black) image.
I've also tried using the drawing cache with the exact same result.
Any one know about how to draw a bitmap image?...
