I ask because I have an old phone running Android 7, and aim not really in a place to upgrade. There's exactly 1 build of Android 8 for this phone on XDA but it's an unofficial version of Lineage that breaks VoLTE, so I don't use it.

All in all, I'm pretty happy with the stock firmware anyhow, I'm just wondering if there's any way to take Android 8's autofill framework and add it to Android 7 as a user app. Something like an accessibility service or an Xposed module.

I have pretty much no knowledge of how to code, so I'm asking here. Any help is appreciated. Thanks!
