(Q)New to devoloping, trying to alter an already built rom. Any guidance appreciated

I just have a couple questions, I've been adjusting theme zips by changing around files in the zip then flashing.
I wanted to alter a rom I have by changing the apks that are in the system/app , data/app, and framework folders. Usually I'm able to view apks as zips, but I'm the rom zip file, I cannot. I can't seem to write in the zip file at all...
And I can't change is permissions cuz when I go into the root section in my xplore file manager, anytime I view the sd or extsd Cards, I don't get the same options.
Any guidance is appreciated

you cant edit files IN compressed files. (zips)
extract the files you want to edit. edit them, then place them back in the zip, overwriting the old versions of the files you edited.
though it is best to extract the whole rom zip, edit then re-zip everything. most recoveries dont require signed zip files, or can be disabled, so you dont even need a special tool to re-zip them most of the time. just use windows zipping. or win rar with 0 compression.

one of the top posts is how to make recovery flashable zips.

how can i install . help me my brothers

my rom is stock odex i used universal deodexer and deodexed my.system/app and system/framework folders . now my question.
how can i install that app and framework folders to my phone ??(i tried replace with root explorer but it does not .(
how can i make thats to a flashable zip?

but
my problem is not that . i can make a flashable zip . its working fine but after i flashed old .odex files doesnt delete. how can i add it to meta inf for when flashing delete app and replace new app and same for framework

No need to create any kind of meta inf you just need to find any flashable zip may be of some kind of theme or update package of your rom if available and just edid it using zarchiver(android) or winrar(windows) simply delete eveything inside the system folder inside the zip except the app folder then delete everything inside app folder then put the apk you want to replace in the app folder. And you are done. Its recommended to sign the zip using apktool(windows) or zipsigner(android) but you can skip this step. Thats about making a flashable zip.
But as far as i know you need to have deodnexed rom to make any changes to system.
Anyways this thread should have been posted in q&a section.

You just need to put in a simple delete line into the update script
for example
Code:
delete("/system/app/Vending.apk");
will delete the Vending.apk from the folder system/app
remember if you are manually pushing files with a root browser you need root permissions and you need to set the correct file permissions - for most apps in the app folder it will be rw-r-r

thnx
thanx i learned if i want to delete folde i will use delete_recursive

help

most likely if the status bar just doesn't show but does not display a force closed message its because the SystemUI.apk is not correctly signed
as long as the file name is correct and it is correctly compiled with no errors the only thing left is the signing
You can sign an apk easily with zipsigner (playstore)
just copy the apk to any folder on your sd card
start zip signer
select your apk as the input
select the name you want to call it for the output (make it different from the input - you can change the name later)
select platform key as the key you wish to sign (this is for system apps for user apps use a test key)
sign the apk
once done the apk will be outputted as a zip file
change the name of this zip to the name of your apk and don't forget to change the .zip extension back to .apk
put in a flashable and flash in cwm with system mounted
you can check any errors with the SystemUI.apk by doing a logcat via adb as the phone is starting up
By searching the logcat for SystemUI you will be able to see any errors in it and why its not starting - eg Signature mismatch skipping loading

If you just want to install those 2 apps, looks for the Gapps package that contains both, then follow this guide (https://github.com/opengapps/opengapps/wiki/Advanced-Features-and-Options) to install just that 2 apps you want.
