Recent night I published a new version of IT-Books.
The new version including more feelings of Google's material-design supports new API to let us download books directly instead of a WebView or opening external browsers.
Use Retrofit as http-client which enhances ability to internet connections.
The new API is wrapper of a external SOAP into readable JSON, more info to new API can be found here. The new version use this API that is hosted in GAE. Of cos you can check it out and fork to your own cloud. Because of it we discard using http://it-ebooks.info/, but thanks .
Also what new of this version is that the app save bookmarks in cloud what previous versions only for local. Users can keep they permanently, thanks to a Chinese backend here to simplify my works..
In order to get more info can be found in store.
