I'm trying to rotate view with google map v2
I used some small lib which work fine with google map v1
the problem is that rotation does not have an effect.
code snippet:
@Override
protected void dispatchDraw(Canvas canvas) {
canvas.save(Canvas.MATRIX_SAVE_FLAG);
canvas.rotate(-mHeading, getWidth() * 0.5f, getHeight() * 0.5f);
mCanvas.delegate = canvas;

I found two ways of creating a Bitmap from a view. But once I do that, the view disappears and I can't use it anymore. How can I redraw the view after generating my bitmap?
I am learning on canvas and bitmap with paths and currently working on a drawing app where user can draw paths freely on the extended view.
The app also allow allowing user to import bitmap as the background and draw on it.
Code:
@Override
public void onDraw(Canvas canvas) {
int myColor = 0;
p.setColor(Color.TRANSPARENT);

p.setColor(Color.RED);
canvas.drawRect(0, 0, width, 200, p);
canvas.drawBitmap(currentPicture, new Rect(0, 0, width, height), new Rect(0, 0, width, height), p);
canvas.translate(tr
I am writing android app where I have a canvas that can be zoomed in or out and translated in any direction. Now what I need to know is what is the position of user finger ON CANVAS, not on screen. The problem is that I have to write this app with API 9 compatibility.

So I have a canvas that I draw a bitmap onto.. When the scalefactor of the canvas is 1.0f everything works perfectly how I want it to.. However the problem is when I change the scale of the canvas. Either zoomed in or out I run into problems with the coordinates and finding the bitmap so I can move it on touch..
I've tried dividing coordinates by the scalefactor.. multiplying..
