Why the image can't save

"save image failed",but I can't find why.I think your logic is right.Do you have the same problem?

[GaoLeng]

find MosaicView.class, delete logic mTouchRects.isEmpty() on the first line in function save().

[GaoLeng]

just like " if (mTouchRects.isEmpty() || bmMosaicLayer == null)" to "if ( bmMosaicLayer == null )"
