Thanks to wdl1908 for prompting me to do this - should really have done this sooner!
Okay, so basic requirements:
- Rooted Gen 8 (Uruk or chulri method)
- Original Archos framework-res.apk
- zip editor
- image editing software
- .png's to replace the stock ones with
That's about it! I've been using GIMP on Ubuntu for the image editing, and Phatch for batch resizing, but Photoshop will work just as well on Windows.
Edit: Thanks to wdl1908, have found that Gwenview gives much better results when resizing, compared to Phatch or GIMP. Works on both Ubuntu and KDE.
Use your preferred zip editor to unzip the contents of framework-res.apk to your chosen folder. The main folder of interest is "drawable-mdpi".
The Gen 8's use MDPI resolution images (well, A70 and A101 to at any rate. I think someone mentioned the A32 or A43 used HDPI images). Depending on your .png source, you may need to resize the images. I took my images from themes made for the Desire, which is an HDPI device, so I used GIMP/Phatch to resize them.
In terms of resizing, I compared the size of each new png with the original one, and resized. I know p0rkburn just resizes the images to 66%, but I've had problems with some images not coming out the right size that way. The other thing to watch out for is that not all the images need resizing. Also, some of the textfield and tab_select images are different proportions to their phone equivalents, so again watch out for that.
Once you've replaced the images you want to, they need to be put back into the .apk. I used to copy and paste into the framework-res.apk, but that doesn't work for 9patch files. Also, wdl1908's FrameWorkBuilder makes the compile process so ridiculously easy, there is no reason not to use that instead.
To put the new framework-res.apk on the device, I use this method via ADB wireless, which works fine.
EDIT: 9patch files
These can be a PITA, until you understand how they work. I used the following two sources to finally crack it :
If you are changing 9patch files, you have to decompile and recompile using the FrameWorkBuilder.
I prefer using the draw9patch tool, as it lets you check that the 9patch works as expected.
Spent enough time bashing my head against a brick wall trying to sort out 9patch files, so if I can spare anyone else that, feel free to post/PM..
