Question Androind App Port/Optimizing for Nook E-ink

I Need some help to port/Optimizing Android Apps for Nook E-ink ...
I recognized that if we could only add virtual trackball to Nook launcher or add inside Apps we can run some them on nook !
( for Example BeamReader PDF Viewer or ... )

Also I need guide for writing Apps for Nook E-ink !

Thanks !

Here are two URLs which might be useful for you:

http://nookdevs.com/

http://code.google.com/p/nookdevs/
(Click on "Source", then "Browse" to see some source code of applications written for the eink nook.)

There are two main things you need to know to get started:

Although there are two physical screens, the eink screen and the touchscreen, to android it's just one screen. So your app layout needs to look something like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android: orientation="vertical">

<... android:layout_width="600px" android:layout_height="760px"
...
/>

<... android:layout_width="480px" android:layout_height="144px"
...
/>

</LinearLayout>

The other thing is power management; apparently android tries to blank the eink screen, so the eink nook apps have to do something to change that. Look for the screenLock stuff in nookBaseActivity (under nookCommon), or any of the other nookdevs apps.

Good luck!

The successor of vudroid is called ebookdroid.


There are a lot of other programs like offline Wikipedia
(WikiDroyd,Aard Dictionary) that use the plain Android Webkit/WebView
component for display. Every scroll and page turn results in a lot of
page refreshes and flicker. The success of e-ink devices crucially
depends on this.

Info for app developers from support@coolreader.org (Vadim):
Look at N2EpdController.java
http://crengine.git.sourceforge.net/...crengine;a=tre
e;f=android/src/org/coolreader/crengine;h=8f8bd76e84046adca3d70ba4a23f5eb2fb

Author is DairyKnight from xda-developers.
At least you can use it under GPL.
For use in closed project I would recommend to contact him.
