I would like to upload the android system on raspberry zero w, but from what I read this is impossible because of that android has no support for this processor which works in Raspberry zero w.
Can you write me more about Chrome and Chromium?
I don't know if I understood you, but it isn't about the browser Google Chrome web browser, right?
If you have questions about Android 1) forget the RPiZW 2) get a RPi3B 3) post your questions on the right forum where Android has a modicum more support than on here.
I have a ready-made android application that I wanted to transfer to raspberrego.
This application uses the Usb interface in a non-host mode.
I thought to myself not to use this RPiZW, but when I started to explore the topic I learned that android on the RPiZW isn't supported because it has a worse processor.
Wanting to choose from this, I thought there might be some way to recompile or convert the android application to raspberrego, and that was the case.
Can I convert apps written on android to run on RPiZW?
