In Termux, if I type the following code, I would expect it to open the URL in a browser, but it does nothing:

import webbrowser
webbrowser.open("http://example.com")

I don't believe that core devs (and b.p.o.) support running Python on Android.  If so, this should be closed here and your question redirected to whoever supplied your Android python installer.  They might just say that Termux is not a supported terminal.

I think the existence of sys.getandroidapilevel is evidence that Android is somewhat supported, even if it is not supported to the same degree that Linux and Windows are.

for a longer discussion. There's an Android build factory

but I cannot see an official Android buildbot running.

The PR seems straightforward and simple to me, but I'm not an expert on the webbrowser module nor do I have an Android where I can test it to see if it works.

DonaldDuck1313, your NEWS entry needs to be re-written to use ReST (Restructured Text) rather than Markdown:

Change: [Termux](https://termux.com/)

to `Termux <https://termux.com/>`_
