[android-developers] setXfermode not working on pre-ICS
I have 2 images, one on top of the other. I paint a circle in the
front-image with xfermode to let the image bellow show through.
I realized this with 2 views in a RelativeLayout. The front-view acts as
mask and is a custom view.
The problem: Works well in 4.x, but on 2.x the circle is black, instead of
transparent.
The code:
@Override
public void onDraw(Canvas canvas){
super.onDraw(canvas);
c2.drawCircle(X, Y, 50, pTouch);
Paint new_paint = new Paint();
new_paint.setXfermode(new PorterDuffXfermode(Mode.SRC_ATOP));
rect.set (0, 0, getWidth(), getHeight());
canvas.drawBitmap(overlay, null, rect, new_paint);
}
And c2 was initialized to a canvas with bitmap overlay, like this:
Bitmap overlay;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inScaled = false;
overlay = BitmapFactory.decodeResource(getResources(), R.drawable.overlay,
options);
//...
overlay = Bitmap.createScaledBitmap(overlay, newWidth, newHeight, false);
c2 = new Canvas(overlay);
c2.drawBitmap(overlay, null, rect, filterPaint);
Thanks!

[android-developers] How to compress text data before saving in a database
I have a more than 800 records of data, of which each record will contain a variable size of text data. It is this text data (anything between 800 bytes and 4kb) which I need to compress before putting it into the database. It doesn't matter if the saving of the data is a bit long, it will be the reading and decompressing which needs to be fast and efficient. Note that I am targetting tablet devices here. Is there a recommended / best way to go about this ? -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: setXfermode not working on pre-ICS
I forgot:
Initialization of pTouch (used in onDraw()):
pTouch = new Paint(Paint.ANTI_ALIAS_FLAG);
pTouch.setXfermode(new PorterDuffXfermode(Mode.SRC_OUT));
pTouch.setColor(Color.TRANSPARENT);
pTouch.setMaskFilter(new BlurMaskFilter(25, Blur.NORMAL));

[android-developers] Maps api key v1?
I need urgently a key for maps api v1. Is there any way to still get one? The context: I finished an app a few months ago. I want to release it now. Now I see that I need a new map key for the release keystore. Well, I go to the page to get the key, and it says, that I have to port my maps to version 2. I can't do that now. Release is planned now, as said, everything is finished and tested. Is there a way to still get a version 1 key!? Thanks in advance. -- -- You received this message because you are subscribed to the Google Groups Android Developers group.
