Ask Slashdot: Best Free and Open Source Apps For Android?

First time accepted submitter aNonnyMouseCowered writes "One of my favorite freeware Android applications has been pulled from the Google Play app store. While I found a replacement for the app, I've decided to install only apps that won't become obsolete merely because of the developer's whim or lack of interest. With the exception of games, which I don't deem essential for work, I don't want to install potential abandonware even if they cost the pauperly sum of $0.00. My decision has thus far meant installing a relatively crude text editor like BusyBox's version of vi, rather than any one of those full-blown mobile office suites. I've found a short list of open source Android apps at Wikipedia, including the usual suspects, Firefox and the VLC media player. There are also links to two other sites at the end of the article. But even the more comprehensive listings have large gaps in them even when compared 'merely' to the programs available in a typical GNU/Linux repository. So can anyone recommend useful or even just fun Free, Libre and Open Source Software for an Android smartphone or tablet? Free virtual beer to those that can find links for FLOSS programs for editing audiovisual media (Blender for Android?) and documents more sophisticated than HTML."
