well it happens either way: if I call or. I used a breakpoint right
at the line and it bombs when the line gets executed so I know its
that bitmap.
private BitmapDrawable staticBg;
private Canvas staticGr;
both throw the error
staticBg.draw(g);
OR
g.drawBitmap(staticBg.getBitmap(),0, 0, null);
anymore ideas?
Its really annoying. what makes it be recycled. even if it was
another bitmap, i do not call recycle on any of my bitmaps so that
means the GC has to get to them which makes no sense since I still
have references to the object it should not get them.
