[Dev Tools] How to create mods

**OMJ** · #1 (**permalink**) 08-13-2011, 08:19 PM

So you wanna create your own ROM, and add all the latest & greatest mods. So you scurry the popular forums looking for them, but did you learn anything? Anyone can take a modded file & add it to your ROM, but if you want to learn how to create that mod yourself, then this thread is for you.

I will adding all the mods I know how to do, I encourage all other devs to do the same! Add your mod, and I will add a link to your post in the OP. Let's help each other out! Be sure to give thanks to where you learned the mod!

How to add % to stock battery (credit to amikam for showing me!)

-mod is located in /system/framework/framework-res.apk....

-you have to decompile it w/ apktool....c:\apktool>apktool d framework-res.apk

-once decompiled, goto apktool\framework-res\res\drawable-hdpi

-battery icons start @ stat_sys_battery_0.png

-copy/replace new icons

-goto apktool\framework-res\res\drawable

-copy new stat_sys_battery.xml, stat_sys_battery_charge.xml & zzz_stat_sys_battery_1.xml
(personally I just use the 6 stock charging icons, and add the 0-100 % icons, then u don't need to replace stat_sys_battery_charge.xml)

-compile new framework-res (apktool b framework-res)

I would if I had it....the systemui.apk I was using from Freeza had that blank space.....I'm real picky when it comes to that stuff, I've switched to JsChiSurfs systemui.apk & it is correct, no space.
