Я использовал следующий код в Gallery View
и получил следующее исключение. Может кто-нибудь показать мне, где я не прав?
07-18 12:45:59.774: WARN/System.err(6758): java.lang.OutOfMemoryError: bitmap size exceeds VM budget

Мой код:

int height = originalImage.getHeight();
//This will not scale but will flip on the Y axis
Matrix matrix = new Matrix();
matrix.preScale(1, -1);
//Create a Bitmap with the flip matrix applied to it.
//We only want the bottom half of the image
reflectionImage = Bitmap.createBitmap(originalImage, 0, height/2, width, height/2, matrix, false);

//the image plus gap plus reflection

//Draw in the gap
Paint deafaultPaint = new Paint();
canvas.drawRect(0, height, width, height + reflectionGap, deafaultPaint);
