Question

I have been developing the application for drawing, and I have the problem: my application has array of pages (Bitmap), and I need to save/open it. I thought that I can use mechanism of serialization, but Bitmap isn’t serializable and I don’t know how I can save array of Bitmaps into 1 file that user can change file’s location. So, please, give me advice about it. Thank you.

Answer 1

You could do something like the second answer in Android serializable problem

Except, instead of writing to a FileOutputStream, you can write out each bitmap into a ByteArrayOutputStream. From the ByteOutputStream, get the byte array, and put the byte arrays into an array list which can then be serialized.
