## AI overview

This article explains that Android 14 blocks the previous direct method of installing system-level CA certificates, including on rooted devices, but describes newer practical approaches for rooted Android 14+ devices. It also distinguishes system-level certificate injection from enterprise-managed and user-installed certificates, and mentions HTTP Toolkit's ADB-based automatic setup.

## Source excerpt

A couple of weeks ago I published a post about changes in Android 14 that fundamentally break existing approaches to installing system-level CA certificates, even with root access. This has triggered some fascinating discussion! I highly recommend a skim through the debate on Mastodon and Hacker News. Since that was posted, quite a few people have talked to me about possible solutions, going beyond the previous approaches with new mechanisms that make it practical to do this in Android 14+, and there are some good options here. While direct root access to change these certificates by simply writing to a directory is indeed no longer possible, root is root, and so with a bit of work there are still some practical & effective ways to dig down into the internals of Android and seize control of these certs once more. Choose your own adventure: If you just want to intercept an Android 14+ device right now, stop reading this, download the latest HTTP Toolkit, connect your device to ADB, click the 'Android Device via ADB' interception option for automatic setup, and dive into your traffic. If you just want to know the steps to manually do system certificate injection on Android 14 for yourself, jump down to How to install system CA certificates in Android 14. If you want the full background, so you can understand how & why this all works, read on: Clearing up confusion Before digging into this, I do want to explicitly clear up a few misunderstandings that I've seen repeatedly pop up from the previous article: These changes don't affect installation of CAs in other scenarios. As far as I'm aware, CA installation for fully managed enterprise-provisioned devices and the limited user-installed (as opposed to system-level) CA certificates will continue functioning as before. If you're not using root access to inject system-level CA certificates into a rooted device or emulator, you don't need to worry about this. Similarly, it is still possible to soft-remove system CA certific
