Today I finally got the time to try on the AWT Event Hook with Amazon's Booklet/KOS framework. To my surprise, it's so easy and just works like a charm.
The idea:
1. Replace the Amazon msp.jar booklet (the minesweep & go game) with user java code.
2. Hook into the AWT event queue in order to load user code upon request (e.g. hot key combination).
The implementation:
Code is attached. To write a booklet for Amazon KOS (codename for kindle os, i guess?
), one has to implement the following interface:
package com.amazon.ebook.framework.a
public abstract interface a
{
public abstract String C(); // Returns the booklet name
public abstract void c(); // Initialize the booklet
public abstract void B(); // ? Load the booklet ?
public abstract void b(); // Handles open file
public abstract void A(); // ?
/** @deprecated */
public abstract void a(y paramy, Graphics paramGraphics); // painting
/*
}
Upon initializing the KOS framework, kindle will look for all classes in /opt/amazon/ebook/booklets/*.jar and load all classes implementing the above interface.
So what I did was simply replacing the msp.jar with my code and let it get loaded.
Easiest way to use the code: (I suppose you know scp/mntroot stuffs)
1. Create a CDC project in Netbeans with name 'msp'
2. Import all amazon libraries from /opt/amazon/ebook/lib/, and the attached source code.
3. Build the code. Create /mnt/us/log directory for event logging.
4. Replace /opt/amazon/ebook/booklets/msp.jar (Don't forget to backup!)
5. /etc/init.d/framework restart You'll see all the AWT Events logged in /mnt/us/log
Thoughts on future development:
1. Develop a unified 'Application Launcher' (like what in iPhone and Palm
) to load user code from, e.g. /mnt/us/Applications/ with Java classloader. We will be able to start this launcher with key combinations. (Intercept key combination in dispatchEvent())
2. Replace default key behaviours on kindle. e.g. Use 5-way sticks for page turing.
