[TUTORIAL][MOD]Changing all app background now possible :) - Galaxy 3 Themes and Apps

If you ever get bored with the black background in Android, now you can change it by making a few small edits to framework-res.apk/res/values/styles.xml
This will affect MOST of the black background you see in Android (e.g. settings, contacts, mms, installer etc.) with the exception of certain apps that use their on backgrounds (e.g. contacts logs, email etc.).
Difficulty level: Medium
1. Decompile framework-res.apk
2. Navigate to res/values and open styles.xml
3. Locate <style name="Theme">
4. Replace
<item name="colorBackground">@color/background_dark</item>
with
<item name="colorBackground">@color/transparent</item>
5. Replace
<item name="windowBackground">@drawable/screen_background_dark</item>
with
<item name="windowBackground">@drawable/mybackground</item>(if u need an image as background)
<item name="windowBackground">@color/white</item>(if u need a color as background)
6. Locate <style name="Theme.Black" parent="@style/Theme">
7. Replace
<item name="colorBackground">@color/black</item>
with
<item name="colorBackground">@color/transparent</item>
8. Replace
<item name="windowBackground">@color/black</item>
with
<item name="windowBackground">@drawable/mybackground</item>(if u need an image as background)
<item name="windowBackground">@color/white</item>(if u need a color as background)
9. Create a 240x400 png to your liking, name it mybackground.png and place it in drawable, drawable-ldpi, drawable-mdpi folder
9. Recompile framework-res.apk
NOTE: U can give any color which is available in res/values/color.xml.

{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
DONE!
Its possible u might get recompiling error if u dont use base framework....so its better to do this with a base framework-res.apk instead of getting pissed off
Always create a backup before making any modifications!!!
Thanks to AvatarOfFrost for his tut.

Few things..
If you are gonna put an image in drawable folders, don't put same image i.e. 480x800 one in all folder, that's a hdpi resolution.
You should have three diff. res. images for these 3 folders. (Check proper res. & description of ldpi,hdpi,mdpi on developer.android.com
If you want to enforce a single image, put that in 'drawable' folder only.
Using a 480x800 image on Galaxy 3 will cause issues. It's resolution is only 240x400.

ive used a wallpaper 320x480

EDIT:
is only the colour value /white valid?
-> thats the only colour I managed get working
Any other value (#80323232, #00000000, /transparent) resulted in simple black.
EDIT2
I tried only white with alpha #ff, no other colour thats why I asked for only white

Nice tutorial aarun....

Hey can I know which launcher is that?

---

for tansparent.....do 1 thing write the text transarent as value an try....maybe it will work......

---

well... as written, the alpha value for transparent is
#00xxxxxx (xx-> every colour could be taken, it will get transparent)
there is also a color variable defined in color.res which is called transparent
This wording variable didnt worl either.
Only the colour variable white was accepted, whyever...
I will try it with a transparent background picture...
That would also solve the topic.
Keep you updated.

---

actually if its present in colors.xml then it shud have worked......k try out with an image...shud surely work then

---

I am some steps forward
checked the option with the picture
a full visible picture (alpha #ff) is working (even JPG format) but if anythig with transparency this doesnt work at all and results in simple black, like default.
Can anyone confirm this (non) transparency effect?
Cheers

EDIT:
tried to create a picture with solid level and transparent 2nd color
the blue in the middle is seen but it fades to black
so my conclusion:
transparent is not a valid colour for that action
BUT:
it works like a charme
