The base class from which an application should derive in order to receive RS messages from scripts. When a script calls rsSendToClient, the data fields will be filled, and the run method will be called on a separate thread. This will occur some time after rsSendToClient completes in the script, as rsSendToClient is asynchronous. Message handlers are not guaranteed to have completed when android.renderscript.RenderScript#finish returns.
