I'm looking for an open-source library for android (Jar), in which I can open documents or pdf files. I have searched the net and haven't found anything suitable or stable.
My main goal is to show some encrypted files, which my application will decrypt and pass the file to the viewer; meaning that the whole procedure should be secured. I cannot pass the decrypted file to google-docs or any 3rd-party application, due to security issue.
Any help will be appreciated.
Thank you all for your time.
Check out the source code of APV - it's a PDF viewer based on MuPdf library - both are free. You can probably assemble something quickly.
