There is some code that allows you to lock the uninstall an application?

no

I have noticed that there are some pre-installed app that does not allow me to remove them. So I think there might be a way, or I'm wrong?

 

[DonManfred]

The preinstalled apps are part of the android system. Or part of the phone-provider you are using. it that case they are custom-roms. Even the original from google is a custom one... The decide some apps not being deinstalled... there are restrictions about this apps or something.
I dont know a way to set an own app on this "security-list" or whereever this may defined.

You have to have root permissios to install an APP to a Rom.

@DonManfred thanks for the explanation

@Erel, @klaus you know any way I can do for me?

 

[lock255]

@GMan, right! I had not thought.
I can get root access via code?

 

[DonManfred]

Hopefully you can not! It would be a massive securitybreach if that is possible

 

[lock255]

Security issues are both positive and negative, depending on how they look and if the intentions of the developer.

I can get root access via code?

You (may) can - its not as difficult as it sounds:
1. set the depending system directories to R/W instead of R/O
2. copy and install SU (SuperUser) to the system
3. execute SU and set the rights for it to root
4. allow SU to manage the root accessment
5. copy and install YOUR app to the system
6. remount the depending directories from R/W back to R/O

As you see, really simple

P.S.: i forgot: for each OS the SU differs
