Hi, my name is Steve Cock, I'm the main developer for the upcoming Vanced Manager. When xfileFIN first published Vanced 15.05.54, people were upset because new Vanced used split apk files. The reason for that was pretty simple:
Main problems with new format were either with device CPU architecture or MemeUI shit with MiUI optimisations. We wrote instructions for VancedHelper but no one used it for troubleshooting. Then some users complained about new format and refused to upgrade to newest version (We don't give a fuck about that) because "I dOn'T WaNT To HaVe OnE MoRE apP To insTalL VanCeD" so we decided to make an installer for Vanced
Vanced Manager is an universal utility for installing/updating Vanced and MicroG. It will push notifications once the update is ready and for root users, it can also automatically download and install them (Now that's what I call pwetty epic).
Vanced manager comes with a slick UI ~~that was stolen from the new Magisk Manager (I'm very sorry John but I looked at your code for about 100 times).~~ Actually, while UI may look very similar to new Magisk Manager's UI, It's still very different (that's a blatant lie, I know).
