In general, I'm not sure I'd really recommend use of the default browser
for Hotspot 2.0 OSU purposes on any platforms, i.e., I'd much rather use
something similar to browser-wpadebug.c than browser-android.c.
Obviously, wpabebug is unlikely to be the best choice for such an app,
but it is an example that shows how simple it is to implement the needed
functionality.

The main benefits of using a custom app instead of default browser are
both in usability (clean bring up of the web browser and robust way of
closing it (that "input keyevent KEYCODE_HOME" is for the default
browser is far from optimal) and in security (maintain separate context
that does not share cookies or other stored values with the main
browser). It should be noted that the URL for the Hotspot 2.0 use cases
comes from an external device and it is not exactly good to accept any
random URL and launch it in a web browser that is used for most of the
normal web site browsing on the device.
