I want Python for Android.
Ideally, it would compile to Dalvik/ART or ARM. It would use something like PySonar to infer types or use annotations to be able to use native types when possible (for speed & correctness). When the type isn't given or can't be deduced, it would fallback to boxed objects (like Nuitka does, in the way the offically C-Python keeps its objects in memory).
But that is not neccessary, all that is needed is a decent wrapper to the Android API for Python, and some packaging support. It is now already possible to compile Python for Android to include it in your app. What I'd like to be able to do is to write the whole thing in Python (+ a GUI design tool maybe).
I already see some people saying, that's not possible, because an interpreted language uses too much resources (CPU, memory, esp. battery) for mobile. Well, 90% of the apps I use are not computationally expensive. The consume battery mainly via network access, and via the screen, both of which is independent of the language or runtime used. And when they are doing something computationally intensive, it is usually the layout and drawing of the GUI - most of which is done by the native framework anyway. Most apps are literally just fancy listboxes and details pages, with a database and a web backend. (The great exception are games, of course.) For these apps, a rapid development language like Python (or Javascript, or heck, a new VB) would be great, ideally augmented by good tooling. And if you have something CPU intensive (map routing, image processing, complex translation etc.), you'll just write it in a C library anyway.
