AndroidManifest.xml user defined data - is it possible?

I'm thinking about 开发者_开发百科possibility to put into AndroidManifest.xml some custom data. E.g. version of SQLite database for this particular release of app.

For sure i can put those data as hardcoded in sources or somewhere in preferences, but still I'm just wondering is it possible?

Why not put it in a res/values xml file (maybe res/values/strings.xml) as a constant?
