DK> Is it possible to use texlive in a closed-source commercial app?
DK> In other words: Can I compile and use TexLive in a paid Android app?

DK> You mention in your license document: "In short, this means that all the
DK> material in TeX Live may be freely used, copied, modified, and/or
DK> redistributed, subject to (in many cases) the sources remaining freely
DK> available."

DK> Does that mean that when using TexLive the source code of any app that uses
DK> texlive must be made available?

TL has many applications with many different licenses, from public
domain to GPL with everything in between.  

However, ALL these licenses allow you to compile the code and use it
in any application you want including a closed source Android app.
Some licenses require you to make the source of these applications
(but not yours) freely available. Many people solve this by adding to
their commercial product the text "This product uses GPL software; you
can get its source from ..."

So yes, what you want is possible, if you acknowledge TL and give your
users a link to TL sources.

However, if you want to MODIFY the sources or link them as a library,
you must be careful and read the individual licenses.  Some code in TL
can be used this way, some cannot.
