[Q] Where are .apk files located?

I'm trying to find where all the .apk files are located on the Nexus 4. I'm rooted and I can see the system .apk files under /system/app. Where would the .apk files be located that I have downloaded from the Play Store?

I beleeve in data/app at least for the free ones you downloaded

[Q] How to install cereberus.apk as a system file?

Hi
I have a question because I don't know how to install cereberus.apk as a system file.
I have single .apk file but in system\app I have some folders with apk files inside.
Do I need to make folder for my apk file or only copy this and change permissions (644)?
And which is the best place for this apk:
*system\app
or
*data\app?
Thanks a lot

If you are rooted you can use titanium backup to change it from a normal app to a system app.

Alternatively you can drop the apk into system/priv-app, fix its permissions and then reboot.

[LGH870][Oreo] How to integrate apps update in rom.

After update from nougat to oreo, I've have problem with integration updated apps in to /system.
I do it like this:
1. copy apk file from data/apk to sd card
2. rename copied apk file to name of /system apk
3. extract lib folder from apk
4. copy newer file to proper folder in /system/app or /system/priv-app and replace file in it
5. Copy lib files extracted form apk to right folder /system/lib or /system/lib64
6. Uninstall update from /data/app
7. reboot + dalvik-cache wipe
In nougat it was working, but in oreo, app after integration, breaks. It cannot be open, and app name changes to random words (ex. google docs name changes to "write com.android").
To repair integrated apps I have to perform a full /data/ wipe.
Is it a some kind of protection? How to do it properly?
TitaniumBackup and Link2SD cannot integrate updates to rom properly without errors since Lolipop.

So no one knows?
or just nobody wants to write?

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.
