PSPDFKit for Android was recently released as version 2.0 including annotation editing support. We've spent a lot of time in making annotation editing easy – both for developers integrating PDFs in their apps, as for end users. Here is an example of how to create a NoteAnnotation with PSPDFKit:

PSPDFDocument document =  ...

// Create the annotation.
final int pageNum = 3;
final RectF pagePosition = new RectF(10, 10, 30, 30);
final NoteAnnotation annotation = new NoteAnnotation(pageNum, pagePosition, "This is a note with cross icon!", CROSS);

// Attach the annotation to the document.
document.getAnnotationProvider().addAnnotationToPage(annotation);

There's also a bunch of ready-to-use UI components for annotation creation and editing. PSPDFKit is a commercial product, but we offer demo versions which can be requested on our website.
