Hello Guys and Galls,
I want to change the background of Settings.apk from black to white. I use the FroyoMod Rom http://forum.xda-developers.com/showthread.php?t=815595.
If change
Code:
<application android:label="@string/settings_label" android:icon="@drawable/ic_launcher_settings" android:taskAffinity="">
to
Code:
<application android:theme=[COLOR="Red"]"@android:style/Theme.Light.NoTitleBar"[/COLOR] android:label="@string/settings_label" android:icon="@drawable/ic_launcher_settings" android:taskAffinity="">
in AndroidManifest.xml.
I use ApkManger to decompile and compile. The (de)compiling is without any errors.
After compile with ApkManager i do the follow:
- open original Settings.apk and unsignedSettings.apk with 7-zip
- delete AndrodManifest.xml in original Settings.apk
- copy AndroidManifest.xml from unsignedSettings.apk to original Settings.apk
- copy the modified original Settings.apk to the phone in /system/app
- chmod 644 Settings.apk
- chown root:root Settings.apk
So now if I start Settings nothing happens, nothing, not even an fc.
This is was logcat says:
Code:
com.android.settings has no certificates at entry AndroidManifest.xml
What I´m doing wrong?
Try one of the many apk re-packaging tools on this forum. Ive used apktool but there are some front ends built for it
From something awesome

By the way if I change any other xml file in /res there are no such problems.

solving the problem? because I would be interested
Me too, I'm having a problem recompiling an AndroidManifest.xml with apkmanager 5.0.1., it won't install unless I use an original AndroidManifest.xml file first, then I can flash right over it. At first I thought it was a the change I made in the file, but I just decompiled and compiled an unmodified version, and it did the same thing. So its the compiler.
Settings.apk is a signed system app. It will refuse to run unless signed by the same key as the rest of the system apps. Just replacing a single XML in the APK will cause a signature mismatch.
Best bet? I'd say make your change, then use a kitchen like dsixda's to resign the whole system with the test key (I think this is a menu option).
Yep your whole system has to have the same signature. I did this edit for a rom a while back, but I made the settings transparent instead of white background by using Theme.Wallpaper.NoTitlebar. Just sign your whole rom together with testkeys and all should be good until another system app gets changed/modified and the signatures don't match again.

Thanks to Gene Poole and one_love_420, I will try your instructions.
If your after quickly signing a whole load of apk's, I wrote a command line front end to do all the hard work for you.
You can even generate your own private key.

I made some changes to my SystemUI.apk, and I pushed it back, then rebooted, only to find my status bar had disappeared.
So, I restored to my backup, and made 4 copies of the SystemUI.apk to try to find out where the problem lay.
Copy 1: No change
Copy 2: Decompiled and Compiled with apktool. No other change.
Copy 3: Decompiled with apktool. Changed one png. Compiled with apktool
Copy 4: Decompiled with apktool. Edited text in strings.xml and changed a few colours. Compiled with apktool.
Out of these 4, only the first one worked. The rest had my status bar gone. Hence I have arrived at the conclusion that something had gone wrong in either the compiling or decompiling stages. I didn't sign the apk because I read that system apps should not be signed.
Just to make sure, these were the steps I took.
1. Retrieve SystemUI.apk, framework-res.apk, and SemcGenericUxpRes.apk
2. Install frameworks with apktool
3. Decompile SystemUI.apk
4. Make any changes
5. Compile
6. Place on SD card
7. Change \system\ to be RW
8. Copy SystemUI.apk from sd card, and overwrite the one in \system\app
9. Ensure permissions are set to rw-r-r (644)
I have not much idea what else could have gone wrong, but then again, I'm just a newbie who follows others' guides and might have missed out on doing something. Perhaps some kind soul would be able to point that out?
Well, apktool is using smali/baksmali to compile/decompile classes.dex/apk_name.odex file.
The problem can occur when you use different baksmali version when you decompile and also not the right version to compile (as the system expects it to be). You can also experience issues if the apk is not zipaligned properly (check down who to do that)
apktool has the smali/baksmali code inside it so you will need to get the newest version for it for JB for example.
You can check why the status bar is not there when you monitor the logcat and look for DEX related logs in the beginning.
You can also use smali/baksmali on your own: http://code.google.com/p/smali/wiki/DeodexInstructions
and just place the generated classes.dex in the apk
then zipalign -f 4 filein.apk fileout.apk (http://developer.android.com/tools/help/zipalign.html)
then push back fileout.apk (sytemui.apk in your case)
Hello, i would like to modify this systemui.apk but everytime i decompile and then recompile the apk it is no longer functional and is of a smaller size.For example, i decompiled and recompiled the apk without any modifications and then signed it but the file was 2.25mb instead of 2.53mb and didn't function
so can you please decompile the apk and recompile the apk, if it is about 2.5mb please upload the decompiled folder
I have uploaded the systemui.apk nd framework-res.apk
thank you
Hi.
I extracted samsungcamera from qsrom 4.4.2 i9300 nl1, and decompiled it using apktool.
then I modified smali files and replaced
"com.sec.android.gallery3d" to "com.alensw.PicFolder"
"com.sec.android.gallery3d.app.Gallery" to "com.alensw.PicFolder.GalleryActivity"
but after recompiling it with some error I got new modified class ,resourceses, and other xmls,
then I opened original samsungcamera.apk and replaced inside with new class, recources and xmls, and then pushed new samsungcamera.apk in system app gave proper permissions , installed quickpic and restarted,
after restart camera icon shows in app drawer but when opened it force-closes.
