Hi..
I've had problems with Gmail and Maps applications previously with Neophyte ROMs. In that case one of the solutions was removing the apks for these apps from with the /system/app folder of the ROM zip.
My question is:
Is it possible to add our own apks to the custom ROM so that these apks come preinstalled on the ROM when someone flashes it..in a manner, a kind of 2nd generation mod?
Is it possible to add our own system variables and settings files so that the ROM autoinstalls it on First Install? In particular, I'd like to preset my own APN file for the network.
The simple answer is yes.
The entire system folder in the zip file is written to your /system partition, with the full architecture of folders and so on, so any changes made in there will also be on the system, when it is flashed.
There is also a script file, in the META-INF folder, which you can use to run commands to delete or edit something along with the flash, whenever the zip file is flashed. This is a bit more advanced though.
edit: it is the same for the data folder of course, which folders is flashed and where to is also specified in the script file mentioned above.
Thank you!
In that case, for installation of a program like Gmail.apk or Maps.apk, would be as simple as adding the .apk to the /system/app, or would I have to include other files? Would there be dependancies in other folders?
Well the apps have their own data folder on the data partition, but this is for storing changes in settings and so on, and it should be created by the app itself on first boot just like right after you wipe the data partition/factory reset
Thanks..Got some mod modding to do!
So in case I'd want to manually uninstall/manually install an apk, what would be the steps I'd have to go through?
Would there be filesystem config files (like the older Windows versions), or a central database of entries of the likes of the Registry tables of newer Windows? How does Android go about installing a file? Like which folders and files would be modified other than /system/app and /data/app? Any common files with entries? And in case of the latter, whether it would be machine readable or plain text?
Can someone give me a dummy of the system default apk in ver. IMM76D?
or where can I get the original system apk?
I have removed some of the system apk under system/apps/
and the trouble is, I cannot update my 4.0.4 from IMM76D to IMM76I because the update process cannot find the removed apps!
I have tried to download form this:

but the pack hasn't the apps that I need.
can anyone give me a hand please?
I really don't want to format my phone and flash the system again!
THanks!
hi,
i want to know how do devs create an apk file that can edit files in system folder. for example sound files etc. generally a flashable zip is created which will replace the stock file with a modified one. The same thing, this time without going into recovery but being able to do it with an app itself.
Yes, ready to learn.
Hey dudes,
I have startetd to unpack the System image of the Pixel to Port it for Nexus. But the rom of the Pixel is completely different from the normal Roms. (I have downloaded the latest from Googel Dev)
In normal system images are a lot of folders like App, bin, etc, fonts... But in the Pixel's System Image are only four folders and one image. The folders are App, lost+found, preloads and priv-app. The image is "system-other-odex-marker".
In the app folder are a lot of folders witch you have expercted. But if you open them are there only ".odex" and no apk's. Lost+found is empty, preloads has some cool images and a retail demo apk and in the priv-app the same as in the app folder. The image has 0KB and none ending.
My question: What is this for a system? How can I fix my Problem? It makes me simply impossible to port this rom! :crying:
Thanks
Chris
hi people, is there any way to install apk from fastboot? since it does not let me copy it to sytem manually moving the file wing caroeta system / app, thanks greetings
if you have an apk, copy it to your SDcard, and on your phone, in files or some file app, click on it and install it. You will be asked if okay to uninstall from there.
