retain bitmaps on canvas in android

[ntimesc]

I am using android 2.2 and I am loading array of bitmap one by one on a canvas after few interval of time at the same place/position i,e, X and Y position (it is one type of rotated image banner).

Now the problem is
If i am locking the canvas using following code

canvas = holder.lockCanvas();

and after that i am loading some bitmap in on canvas and then lock it using following code

holder.unlockCanvasAndPost(canvas);

then again if i lock the canvas and lode some more bitmaps then previously drawn bitmaps are getting wiped out. so how can i preserve/retain the old bitmaps.

please help me out on this

You'd have better luck in a developer forum. This is a user forum. There are probably some developers that drop by but I wouldn't count on it.
