Pare down gapps package - Nexus 4 Q&A, Help & Troubleshooting

I'd like to take a gapps package I have right now and pare it down only to the apps I want.
This is what I've done, but I wanted to make sure that it's all that needs to be done in order to remove the gapps I don't want.
1. delete apks from system/app folder
2. delete app reference to the same apps in 70-gapps file in addon.d and save
3. re-zip all files
Will this create a flashable gapps package, or have I done something wrong?
Thanks.

Make sure the folder structure is correct, then it should be fine. Try flash it in the recovery, if it flash, then it is correct.
There are some dependencies lib files in "/system/lib" that can be removed. Check inside the individual apk for references.

How do I look inside individual apks?

You can open apks with any zip program (such as WinZip, 7-zip, WinRAR, etc).
EDIT: That is, open them up and view the various files within them (eg. the images, etc). Not sure if that's what you needed, but just clarifying.

how do i deoxed single apks?

iv been looking but cant figure it out, no one gives instructions on how to use there deodex tools
Download AvaboxV2 Here
Unzip the download somewhere, open up the 'De-odexer' and view the readme.
I think you just put the apk and odex file inside the "de-odexer" folder and double-click the ''deodexall.bat" or "deall.bat", something along those lines.
Can't check right now since I'm on my phone

AvaboxV2 won't do that, it will take both the APPNAME.apk & APPNAME.odex files and make it into a single de-odexed APPNAME.apk
If you want the classes.dex file check out smali tools I believe that should do it for you. It may decompile as out.dex, if it does just rename it back to classes.dex
Edit: instructions for it are HERE

if it does i have never seen it
i thought when u de-odexed a file that it created a classes dex. im still having problemswith all methods mentioned
attach the apk and the odex files in a zip so I can download them. when I have time I'll see if I can get the classes.dex file for you and let you know what I did to get it

Looking for a tutorial: how to cook a ROM?

I'm looking for a guide which tells how to make a own custom ROM from another one
I mean:
1. How to add/replace/remove apps in /system/app/?
1. a) Do they need to have special permission?
2. How to replace boot screen?
3. How to add custom kernel?
4. How to add Desire lockscreen/flip clock?
5. How to add transparent notofication area?
6. How to add Power menu?
I've been serching forum, but didn't find such tutorial. Would be very thanful to get this knowledge.
I think that will be very useful for maaaany android maniacs
1. Simple delete/copy apks in .zip file using 7-Zip or any other.
2. I belive you need to put bootanimation.zip in /data/local/ folder.
3. Idk
4. For Desire lockscreen you need edited HtcLockScreen.apk; for flip clock - HtcClockWidget.apk
5. Edited /system/framework-res.apk or /system/framework/com.htc.resources.apk. I'm not sure
6. You need edited /system/framework/android.policy.jar
69. Resign your zip file using Auto Sign
Attachment doesn't load, but I know about resigning ROM after everything is done
Ad. 1. As I thought, but do the need special permissions? And I also wonder one thing. Are they installed while flashing? Cuz they need to be in system registry, I think...
I have found this: http://wiki.android.com.pl/wiki/Kon...iana_instalowanych_aplikacji_razem_z_systemem
No any permissions etc.
Found this, too. Thanks.
to add a custom kernel you have to unpack the boot image and edit the ramdisk manually, although i think there is an option in dsixda's kitchen to unpack and repack the boot.img
I've got two more questions:
1. When signing, three files are created in folder META-INF: CERT.RSA, CERT.SF, MANIFEST.SF. But in other packages I see also com/google/android/update-script in META-INF. How to make it? Is it necessary?
2. If I want to make only flashable update file which changes one app or another file, eg. framework-res.apk, I have to create folder structure: system/framework/framework-res.apk, add it to zip archive (no compression?) and sing using Auto-sing. Am I right?
Edit:
Found nice guide there: update-script syntax

The most important part of a recovery update zip is the update script. It will tell the recovery what to do. If you want an example of a basic update package, which replaces one file in the /system/framework (although a different one) can found here. Open this and read the META-INF/com/google/android/updater-script (or whatever its called). The syntax is pretty straight forward and I think its easiest to learn from the examples of updater scripts found here on XDA. For the simple case, of only replacing/adding files to the /system partition you can leave the updater script from the above example as is and only change the files under the /system directory in the zip.
Note, that the above example uses the newer upader-script (I hope I am writing this correctly, I am writing from memory) which also has a binary file in the same directory. Some update zips use the older "update-script" lone text script. For these kind of scripts, you can find a guide here.
Personally, I use RA recovery, and for this recovery you need to sign the update zips (last thing you do of course). At least for RA recovery, both the older "update-script" and the newer "updater-script" work fine, so its up to your personal preference which do you prefer.
Thanks. Found a guide you mentioned a couple of minutes ago and read it.
The more I know, the more questions it brings So one more thing. If I'd like to use the newer version of syntax: "updater-script", I need also to put this binary file in this folder. But I create/edit only "updater-script", binary file is the same for all packages, or do I need to edit it, too?
I built a kernel tool long time ago, very easy to use (only for linux)
1: unzip the file, place it where you want it eg your desktop
2: place boot.img in the working directory
3: double-click the menu icon or launch from terminal
4: it creates a new directory named BOOT-EXTRACT,edit what you want in there or change the kernel etc.. and repack it again via the kernel tool
see screenshot. here for those how want the tool >>> http://www.elelinux.se/tools/kernel_tool.zip
Edit: Only for Hero

Only the updater-script. The binary is a replacement of the script-interpreter I think, but thats just an assumption.

That's mine assuption, too, but would like to know it for 100%
Edit: I see you use it in your kernel update package. So you write only updater-script and place also update-binary next to it?
LOL, you've got help from every well known hero dev on xda, I'm sure you'll have all the info you need now to start building rom's. Good Luck!
Found an app called Easy Flashable zip Builder on this thread. Will test it soon.

But it is for MS Windows, or saw I wrong ? I have also built a tool to javasign files,but should probably write a manual first,it is easy to use but some dependencies maybe not so easy for a beginner with Linux.

[Q] How to sign Blur system apps

i have modificate blurphone.apk ( just a png file) and after this steps (Link) I have no network and fc.
Somebody can help me? I have read a lot of things about how to sign and modificate apps but nothing yet about Motorola blur system apps.
Thx
If you are modifying simple png picture then you can do it without decompiling and compiling, just extract with 7zip and modify them and install it back via flashable zip.
Did you tried to put the apk without signing ?

[Q]When we need copy file/folder from original apk after modified?

Sometime in mod guide.. we need to copy file/folder in original apk after modified... like androidmanifest.xml/classes.dex/etc.. so my question is when we need to copy it?
I only copy meta-inf and androidmanifest to the build folder (you need to compile the folder to get the build folder and then recompile again after placing files there) if im not resigning the apk

so you want to say that if copy meta-inf and androidmanifest to modded apk, we dont need sign apk.. that what you mean?

But in this guide forum.xda-developers.com/showthread.php?t=2018688 the additional instruction said copy classes.dex from original unmodified apk and paste it in modified apk.. when this step is necessary?

[Q] Is it possible?

... to "flash" or otherwise install theme type mods such as changing a notification icon, without recovery? I had experimented with framework type flashable zip files to do with on my GS3 and always flashed from recovery. I am trying to (at least for now) keep from tripping my KNOX.
Also is there a wifi hotspot app or mod that also does not require recovery?
With a towel root, I can probably do everything I want, and keep my KNOX at 0, if I can do these two things.

Sure. It's just more work. Having root gives you the necessary permissions to change system files and do anything that a (recovery) flashable zip file would.
But pragmatically, it wouldn't be reasonable to expect everyone going around writing custom install scripts for your theme mods when the common practice is to package them as a flashable zip.
The solution? It would be eminently useful to learn how to make manual changes yourself. Theme mods typically modify a system file e.g. TouchWizHome.apk or SystemUI.apk. You can make simple edits or replace packages with a root aware file browser e.g. FX. And more advanced edits with a decompiler like apktool.

Oh I don't expect others to make my scripts. I was making the zip packages myself.
If I understand you correctly, I can use something like FX to replace the an icon in one of the .apks? Those are zip type files but FX can do that?
As I already said, yes you can. Icons are (usually) especially easy. It's literally just replacing an icon with a file browser, usually in the xxhdpi360 drawable folder of the apk.
Something like
Copy the apk to another directory or your PC
Temporarily rename the .apk to a .zip file
Use FX Root to browse the compressed file and locate the icon you want to change.
Delete the icon from the zip.
Drag and drop the new icon to replace it.
Rename the .zip back to .apk
Browse to the folder where you copied the apk from
Rename the original .apk to .bak in case you need it later
Move your modified apk to the directory
Confirm that the permissions are still 0644 (long press to check.. but I've never seen FX mess them up to start with).
Reboot
That may look like a lot of steps but they are all trivial and you can do the entire thing in about 60 seconds.
Features e.g. suppressing nags or some colour changes may require decompiliing an apk.
