Beside Terminal IDE (which is open source and a great package for VIM users) there is:

- AIDE https://play.google.com/store/apps/details?id=com.aide.ui...

- Sand IDE https://play.google.com/store/apps/details?id=com.jimmychen....

I used Terminal IDE on my Nexus 7 (yeah, too small for actual work) before and with a physical keyboard connected it comes with everything needed to create, build, pack and install Android apps, including native development in C/C++.

Not exactly a blog post, but might be a good place to start: http://www.spartacusrex.com/terminalide.htm
