how do I " flatten" not only signatures, but also text added to a document when saved and closed?

I am working on the Android app and I handle important documents. When closed and saved, I need the fields and the signatures to flatten so the next user can non change the document.

I think you may be in the wrong forum. This one is for Adobe Captivate.  Were you perhaps more interested in Adobe Acrobat?
