The example of running android studio is a great one if that becomes easier than it currently is. (apparently you can do it via termux, if you replace the java runtime in the download)
Develop/deploy on the same device would make getting into android dev much easier. Also, you have your dev tools with you wherever you are, in case you run into a bug or something while testing your app.
The last time I looked at it (several years ago), it had become a subscription-locked money grab.
It was listed as a free app in the Play Store, but when you ran it, you could not do anything without buying a subscription. The reviews for it said it was full of dark patterns and shady stuff.
Some developer blogs described how good and capable it was, but it seems that they were written before the money grab changes.
