A number of apps have similar profiles.

You make two different claims here, one that the Android UI is terrible and
the other that it is unfit
for enterprise applications. The first claim is opinion and therefore
unsupportable. The second is a
rather pointless objection to a system that is intended for running on
mobile devices and it's wrong
anyway. Given that enterprise apps are tiered, and many, many companies
like LinkedIn and Facebook
and IMDB andGoogle themselves program enterprise apps just fine on the
Android platform, the market
seems to have disproven your claim..
Surely you don't think HTML is superior to Android Java for UI programming,
yet it has been a part of
enterprise apps since the term "enterprise app" was born.

In money?
I'm sorry you had such a bad personal experience with fragments. I know
quite a few Android
programmers who produce highly complex enterprise clients using fragments
in a matter of weeks.
Sometimes new ways of doing things can be a struggle to learn, as one
forces new patterns and ways
of thinking on oneself against the inertia of years of doing something
another way. Some people fall
into the trap of blaming the tools for their difficulty, whining that they
suck or don't implement the proper
cognitive model, and impede their progress even further.
No matter how good you are on the accordion, you might be defeated by the
violin. But for those with the
talent and the perseverance, enlightenment and the concomitant skills can
be attained.
But even the best of programmers on the best of platforms with the best of
tools encounter, oh, how did you
phrase it?, "random [sic] misbehavior".

Including on the Android platform. Including by Google.
