How can I add and edit bookmarks within a PDF on Android?
Direct editing of PDF content is something hard to achieve. As far as I know, the only solution for this is Qoppa PDF Notes. However: bookmarks (create &amp; edit) and annotations (also create &amp; edit) are possible.

The best eBook-Reader on Android, also known as Moon+ Reader Pro, supports this not only for PDF (Pro only!) -- but also for EPUB and other formats (Pro &amp; Free). Another popular solution (PDF only) is ezPDF.

For more solutions, you might consult the Playstore, and check with the descriptions. The keywords are "bookmark" and "annotation".

Another Q&amp;A here which might prove interesting to you is: Is there any software for Tablets to edit PDF or PS -files?
