Android uses a static resource file R. This file (at least in eclipse) is automatically updated when ever you add new id’s of any sort. How can I create/implement the same feature in a normal java application? Is it as simple as just writing an xml parser and just updating the resource file after the xml is modified?
In a way, yes. You need to create a custom build script/program which runs at the start of each build (before anything else), scans your resource folder files (and if they are XML files it needs to read in the XML files and parse out the string resources or whatever from those), then write it all to a Java file in some manner (e.g. R.string_name = “string value”).
Make sure the XML files aren’t actually packaged in your .jar, since all that information will be stored inside your Java resources file now.
For things which aren’t XML files you could just store the filename as a string in the Java resources file.
