canvas.clear will turn base color to white.

[ninonur]

I have put
canvas.setBaseColor(Color.TRANSPARENT);
because I have an imageview below canvas, for my simple photo/image doodle editor.
But whenever I call canvas.clear(), the whole screens goes white. And if I using eraser on canvas the below image/photo appears. I figure out that the base color has change to white because of something inside clear void.

So I try removing or replacing paint.setColor(Color.WHITE) to paint.setColor(baseColor) inside clear() void. Testing the base color to regular color(red,blue,etc) will work. But if I put Color.TRANSPARENT will make it clear NOTHING at all.

i have tried clear() and it turns screen to white.
So what im doing is while(canvas.canUndo){canvas.undo();}.
When a bitma is drawn, it can't be reverted using undo();
