title: Android SQLite R-Tree - How to install module?
body: <p><a href="http://www.sqlite.org/rtree.html" rel="noreferrer">http://www.sqlite.org/rtree.html</a> says that the r*tree is "included as part of the amalgamation but is disabled by default" and to enable it "simply compile with the SQLITE_ENABLE_RTREE C-preprocessor macro defined"</p>
  
  <p>Well I want to use R-trees in my android app, but clearly SQLite is all pre-installed etc. Is there a way to enable it on a user's phone/device?</p>
  
  <p>Alternatively, is it possible to use the NDK and the freely available source code for SQLite?</p>
