remove chrome's apk (trichrome library)

[deleted]

Hello, how to remove trichrome_library without pc?

flawedworld

It's an OS component and is part of Vanadium. Don't touch it, you'll break Vanadium and a lot of apps. We aren't going to give support telling people to break the OS.

It installs with the chrome application

[deleted] You mean you installed Google Chrome from Play Store and wish to get rid of the Trichromelibrary that gets installed as part of that?
If you have installed Google Chrome, then there is no way other than using adb, to my knowledge to uninstall

com.google.android.trichromelibrary

You should be really careful.

You could easily uninstall the other trichrome library @flawedworld mentioned above and break very basic functionality.

The one you should NOT do anything with is

org.grapheneos.vanadium.trichromelibrary

ayaen I don't want to touch vanadium. Only chrome

ayaen

[deleted] Yes. In that case you will need to use adb to uninstall the trichromelibrary which comes as part of Google Chrome.
I have given the app ID above.
com.google.android.trichromelibrary

At the moment it seems that the only way to remove the Chrome's trichrome library (or any user-installed library) is by using adb (which I'm not particularly fond of).

[deleted]

And what is very strange is that when I uninstalled chrome, I reinstalled it and the play store asked me to reinstall trichrome library ... in short to be sure to do well and as I have no computer I reset my phone

I think it would be a good idea to warn people before they install Google Chrome.
That they should have access to working adb in case they decide to uninstall it as
a 'clean' uninstall would require using it to remove com.google.android.trichromelibrary.

Wonderfall

ayaen Agreed, that's exactly why I opened this issue. Maybe it could be addressed in the future.

Wonderfall No need, vanadium is fido2 compatible

Wonderfall

[deleted] This still needs to be addressed for other apps that might require this. Also, some people want to use Chrome for its synchronization features.

Vanadium being compatible with FIDO2 is great news, but the issue is still somewhat relevant.

[deleted]

Wonderfall OK. Thanks

Wonderfall

@[deleted] Make sure it's uninstalled by running adb shell pm list libraries. I had to run the uninstall command a few times to get it removed despite adb returning "Success" several times.

Also, make sure to turn off developers option once you're done. adb should only be used when necessary (from a trusted device) and turned off otherwise.

[deleted]

Wonderfall If one does not feel comfortable tampering with adb, then leaving Chrome installed until there's a way to get rid of the library is probably the safest way to go about this, am I right? Usually I delete unused apps but I guess the library can't be updated without having Chrome installed?

[deleted]

Wonderfall OK thank you

Wonderfall

[deleted] I'd say it's better to keep code updated than not updated. Fortunately unlike stock OS, Chrome does not serve the WebView. But still, you want to avoid extra attack surface (ideally).
