• APP load html file should end-with '.html', or develop in SPA mode
• resource urls should not start-with '/'
• document.location.protocol+"//"+window.location.host is "file:///" on app, besides history.back() doesn't work, so links(window.location.href=) should use "file:///android_asset/www/*.html"
• generate json: node ./util/book.js

Goal: nothing, maybe in case the wechat pages may disappear one day

1. https://mp.weixin.qq.com/s/_1EKspDEvY-iblF7ba-0Aw
2. • 1A
   • 1B

• user script: scroll.js to help download lazy-load images
• use picture.sh to generate images resources.

Goal: Electric book reading has better User Experience, EnglishBook app free version run with annoying ads, while ads-free version charges monthly, which is too expensive(I think).

• use a rooted android emulator(such as yeshen), to install EnglishBook app and rooted ES(com.speedsoftware.rootexplorer), download books in app and then use ES to browse files of the app.
• files downloaded even in app are encoded, but find the log files of the app, find original resources on github, so download them.
• setup book reading webservice.
• generate book list from app file directory
• setup book info marking webservice.

PS: I've found another PDF and mp3 resources on BaiduPan, PDFs and PPTs can play on my Xiaomi Phones.

Goal: ocr and Speech Recognition tech to auto generate marking information.

• ocr to get texts from images
• Speech Recognition to get timestamp of the texts in the audio
• generate json files
• generate pptx with images and audio(auto play), test playing on Phones.
• online pdf reader(pdf.js), and pdf to images, pdf to pptx, images to pptx.
