Build me an Android app that acts like a personal AI assistant and can actually do things for me on my phone, not just chat. I want to be able to type or speak one simple request like send a message, summarize a long chat, find the cheapest option on a website, check the weather every morning, or fill in a form, and have the app open other apps or the web and complete the task in the background while I keep using my phone.

It should work with normal apps by looking at the screen and tapping around like a person, and it should have a hidden background screen with a small live view I can open if I want to watch. Make it ask me before anything risky like paying or placing an order, but otherwise just get it done. I also want it to stay on device as much as possible, let me connect my own model key or account, and remember preferences so it gets better over time.
