I have several Fire HD 8s which I purchased with the intent of only allowing them to open 2 PDF files on the desktop. Seeing that there was no native way with the Amazon OS to do this, I ended up using ES File Explorer to publish the files to a clean desktop and ADW launcher to lock down the desktop. The limitations are that: ADW does not lock settings if you swipe down from the top and when you are in the PDF and exit, you go back to the Amazon launcher and not ADW. If I could fix these 2 problems it would be great but I am trying not to root the tablets and was thinking that maybe I could use a child profile and somehow publish the 2 PDFs to the library as a nice workaround but I have no idea how to publish that data so amazon sees it as content a child profile could access. Any help would be greatly appreciated. Thank you!
