How to support multiple android version in your code?

Question

Take accessing contacts in android android.jar for versions 1.6 has People.CONTENT_URI for invoking contacts related info whereas in later versions we need to have api suppo

Answer 1

Best practice (though not for Android, but for J2ME) to my knowledge is to use preprocessing C/C++ styled statements, like:

//#if S40
    ...
//#else
    ...
//#endif

Some IDE's support these kind of preprocessing, e.g. Netbeans. To my knowledge Eclipse has some plugins to enable preprocessing also. I don't really know are they applicable to Android development. Try to google yourself.
