In java
there is class SchemaFactory
which is used for schema validation but it is not available in android. Is there any other option available?>
There is currently no XSchema support in Android. This was true in version 1.0, and I just looked at the changes in 1.5 and no changes have been made to any of the xml packages, so it appears to me it's still true. I don't have the source > 1.0 though.
In the 1.0 source code there's the following comments in various parser classes:
// TODO No XSchema support in Android 1.0. Maybe later.
So you'll have to bundle your own classes or skip schema validation altogether for now. It's probably not a high priority feature for them.
