Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

Duokan OS is clumsy. So let's strip it down to launch the PDF reader from Kindle launchpad. We will need to extract the Duokan atchive and then copy select files to the Kindle DX.

Prerequisites:
1. jailbreak
2. launchpad

Create the following folders in the root folder of Kindle:

Code:

DK_Documents DK_Pictures DK_System
Extract the Duokan archive
Copy the following folders into the Kindle

Code:

DK_System/lib DK_System/system DK_System/Savers DK_System/bin/DKPrivateProfile DK_System/bin/doc2html DK_System/bin/ebook
From the DK_System/DK_Update folder select the subfolder corresponding to your device (dx, dxg, k2, k3). Copy its contents to the DK_System on Kindle, except for the bin subfolder!

To delete this stripped down version of Duokan from your Kindle, just delete all folders DK_*.

Re: Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

Sample: After unpacking Duokan_0_5_13_8734__2011_03_05_english.rar and copying select folders I got the following on my Kindle DX:

Re: Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

How to launch PDF reader from launchpad:

Create DK_System/startdk.sh file on your Kindle with the following content:

Code:

export LD_LIBRARY_PATH=/mnt/us/DK_System/lib/:${LD_LIBRARY_PATH} 

chmod a+x  /mnt/us/DK_System/bin/ebook 

/mnt/us/DK_System/bin/ebook >/dev/null 2>/dev/null 

/etc/init.d/framework start

Create file launchpad/duokan.ini on your Kindle with the following content:

Code:

[Actions] 

D S = !source /mnt/us/DK_System/startdk.sh & 

D X = !killall ebook

Press Shift -> Shift -> Space to re-initialize the Kindle launchpad.

Now if you press Shift D S (duokan Start), the PDF reader will be launched. If you press Shift D X (duokan Exit), it will be closed.

Re: Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

How much better is duokan with PDF's? Can it adjust, zoom and justify text? May give this a go if it can!

You can zoon, use PDF reflow,... Watch the following video. It is not in english, but should give you an idea what duokan is:

Re: Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

I had been using duokan on 3G Kindle 3 for a while. I really liked your approach which kind of lets one of the best features being accessed through kindle fw.

I installed jailbreak, launchpad and then followed your instructions. I already had duokan installed on my kindle3, so I changed the names of existing DK_xxx files and then proceeded to create the folders and move files as suggested by you. I am using latest version of duokan.

Now when I press Shift D S it reports that action is completed successfully but then nothing happens. The pdf files open as they used to in kindle. Duokan reader does not start. What am I not doing correctly. Will appreciate your help and guidance. Thanks.

Re: Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

Try to re-initialize launchpad shortcut database by pressing Shift -> Shift-> I on the Kindle keyboard.

Re: Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

It did not work so I started the whole process from the begining.

I am using April 22 version of duokan, btw

When I come to step 4 as outlined by you, I found that in DE_Update in k3 there is a subfolder called DK_System.

Am I supposed to move this subfolder to DK_System on kindle and then delete or remove the bin folder as contained in it?

Or, am I supposed to move the contents of this DK_System subfolder? That poses a problem because it contains a subfolder called system and we already have subfolder system in DK_System on Kindle.

When I look at your code, I see config.ini file. I see this file in DK_System within the update/ks subfolder. Can you help me overcome this confusion which may be caused by different versions of duokan or by my sheer stupidity, either.

Thanks.

Re: Stripping down "Duokan OS" to launch PDF reader from Kindle launchpad

I put the contents of update/k3 subfolder into the DK_System folder (except the bin folder).

Now when I pressed shift shift space it went ahead successful.

Then I pressed shift D S and that went successful too. Now at this point I am not clear as to what is supposed to happen. Does duokan run or what?

However, nothing seemed to happen.

Then I pressed shift D X and it failed.

Then I pressed shift shift I as suggested by you, that too failed.

I really like duokan and I am very keen to access its pdf capability from within kindle but so far all my attempts have failed. I hope you can guide me through this. Thanks a bunch.
