How to tile and scroll a large image (10000x10000) in android

Question

I am working in a map project in android. It contains larger image of 10000x10000 resolution. Using this image with Bitmap it gives OutOfMemoryError

Answer 1

Someone I know ran into the same problem. They solved it by first splitting the image into square tiles. Then they generate an HTML page that displays the images in a

layout and get the built-in browser to display the resulting page. This means the browser manages the visibility of the images, and it gives you bi-directional scrolling and pinch-to-zoom.

This approach is very easy to code, but loses the flexibility of writing your own custom solution. This was for a smaller image (2000x1500 ish) so I'm not sure how it will scale to the dimensions you need.

If you do go this route, make sure you have border="0" cellpadding="0" cellspacing="0" on your table and border="0" on the images to ensure that the joins are seamless.
