I would like to draw shapes and write notes on Pdf Reader of Kindle Paperwhite. Have you got any idea to create such a native tool?I think it isn't so hard.Here is my solution:
- Write a native app that is similar to "/usr/bin/xtestlab126".But It won't clear background when it opens.
- Listen a specific gesture event of touch screen.After that event, run this drawing app.Note: we should run this drawing app anytime.
Can we put a "nop" bytecode to disable clearing background.Instead of writing new app, we can edit bytecodes of xtestlab126.I uploaded "xtestlab126". Maybe you could patch this app using IDA Pro
