porting hdpi ROM to mdpi - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I recently started to mess with android system. I learned how to port ROM's between devices with the same screen size. The problem popped up when I tried to port a NEO V ROM to mini. I got it running, but the screen was was too big for the mini.
Can anyone give me a clue on how to port screen size please?
I've searched google, but no success on porting different screen size ROM's

All app images and framework are of different size. You will have to resize every image. A lot of work.

I advice you to use faststone resizer, instead of resizing image by image..

Thanx for replying!
I'm just starting to understand how android works so any help is welcome
I know how to open apk's and resize images in them. That's no problem.
But as far as I know everything in the framework folder is java .jar?
Any hint on how to to resize framework?

you can port mini framework to ported rom.may you change density display to 160?

thanx for helping!
Changed "ro.sf.lcd_density=" from 240 to 160 and it worked alright
Then I replaced hdpi system apk's with the same mdpi system apk's for now. All working ok
As for unique system apk's, I'll resize png files with image scaler.

or even between mdpi would be great, asked a lot of people, no one gives clear sets of instructions, just pieces
something organized would be greatly appreciated

I'm definitely no dev, but I'll try to put something together for you

It's nothing more than replacing/overwriting files&folders.
This is what worked for me. I'm no expert, I figured this on my own. So it
may or may not be all correct. Feel free to correct me, I'm happy to learn
If you port mini/minipro/live/active, you don't need to replace camera
drivers or bootanim since they have the same cam and bootanim res.
If you're porting NEO ROM, you have to replace camera or it won't work.
These are folder/files you have to copy from mini ROM to ROM you're porting:
in /etc replace:
/firmware folder
ppp folder
wifi folder
sensors.conf
hw_config.sh
pre_hw_config.sh
vold.fstab
in /usr replace:
keychars folder
keylayout folder
[it's for hard and soft keys]
in /system/lib replace:
/hw folder
[contains the files which control the sensors and lights such as GPS and
the accelerometer]
>>>build.prop<<<
You have to change ALL MT11, SK17, ST17 etc. entries to ST15i.
Also replace codenames i.e. mango to smultron.
It's best to have a mini build.prop side by side and just do some
copy/pasting
-------------------NEO V [HDPI to MDPI only]-------------------
-CAMERA driver-
in /usr/semc replace:
camera folder
/lib/
libarccamera.so
libcamera.so
libcameraservice.so
libcamera_client.so
libCaMotion.so
liboemcamera.so
libseccamera.so
libseccameraadaptor.so
Replace bootanimation in /media
>>>APK replace<<<
If porting NEO V to mini (hdpi to mdpi), you have to replace some APK's in
/system/app.
Replace only SAME APK's from mini ROM to NEO V ROM.
That's what I did anyway.
All other apk's you have to resize to mdpi.
You can do it the hard way and resize ALL png's inside the apk's to mdpi.
I just replaced those same files and that's it. I was testing anyway.
If you don't do it, you'll have a hard time with apps since they'll be too
big for mini screen.
Also for HDPI to MDPI, find this line "ro.sf.lcd_density=" and change it
from 240 to 160
Or you'll boot into a seriously wrong sized screen
-------------------NEO V [HDPI to MDPI only]-------------------
That's it!
I hope I haven't forgot something
If you find this useful, I may post it as a thread....

I didn't convert at all it would take to long.
I just replaced the apk's with identical, but MDPI sized apk's from another ROM.
Most ROMs have similar sys apps. If not take from two ROMs...

I'm no real dev
I'm just experimenting. So I think you might get much better help from like expeacer or ramezzidane. They're MIUI devs.
Also kamarush seems to be willing to help a lot of folks. So you might ask him too, he's a great dev
