=INTRODUCTION

I compare the following Open Street Map implementation

- OsmAnd http://osmand.net/
- Big Plannet Tracks http://code.google.com/p/big-planet-tracks/
- MapDroid http://tedp.id.au/mapdroid/
- RMaps2 http://code.google.com/p/robertprojects/

I think RMaps2 is one of the most active project, 
simple design and small footprint.
So I choose it as a base project to realize a offline map feature.

=Building RMaps2 base Android module for Titanium

- first of all, generate android resource, R class.
  (Titanium doesn't support it at this time, so I wrote ant target in build.custom.xml)
  > ant rsc-gen
- type ant.
- copy android resource files under res folder using ant target copy-rsc
  > ant copy-rsc

NOTE: Titanium mobile module building system also doesn't support Android aidl,
      but I wrote pre.compile hook(1.6.x series doesn't have this hook, use 1.7.x)
      (see /Library/Application Support/Titanium/mobilesdk/osx/1.7.0/module/android/build.xml)

= Building example Titanium app using RMaps2 based Android module
- copy org.appcelerator.openstreetmap-android-0.1.zip into example/TiUIOpenStreetMapExample
- build TiUIOpenStreetMapExample project using Titanium Developer/Titanium Studio


=PROBLEMS:
- post.jar,  hook doesn't. I don't know why.
- properties, manifest.moduleid and manifest.version are blank in build.custom.xml
  even though there is a line <property file="${ti.module.root}/manifest" prefix="manifest"/>
  so I gave tricky lines in build.properties, those properties will be set manually in it.
- RMap2 based Android module has these errors:

=TODO
- current version's RMaps2 is not support Android 1.6
- add public methods and properties same as Titanium.Map.MapView
