Hi Scott et al,
I have been running an rp3 with raspian (debian GNU/Linux for the raspberry pi) for about 6 months. At first there were problems with stuttering speech using speakup (screen review package for linux). I have been a debian (and other flavours of linux) user for about 20 years. Debian on many platforms can be installed with speakup from the cli without sighted assistance.
At first, I had to ssh from another linux box into the rp3 to compile the kernel with patches for speakup. It was a disappointment. Now there are raspian images including speakup that can be installed on the microSD card from any machine. (see the raspberry vi website (spelling is correct: vi) You then put the microSD into the RP and it boots, runs with good speech and you have a full featured debian box on the rp. Many standard debian packages are available from the rp servers, including, I believe a full asterisk setup.
Of course this is running debian, not android on the rp. I haven't had time to test out android on the rp. It's still on my to-do list. <grin>
Anyway, a partial answer to your question: You can develop software on the rp under raspian. There are lots of development tools, gcc, make, emacs, etc.
