iPhone export is described @ http://www.tersus.com/#Id=3285 (see at the bottom of the page - requires a Mac for the final stages).
Android export should work without extra steps. I.e. once the SDK is installed, and the studio configured to locate it (which should occur automatically on first export, but can be overridden later via Window>Preferences>Tersus>Application Export Wizard), export should launch the application in the SDK's virtual device emulator.
Which version of Tersus (Help -> About Tersus) and the Android SDK (About option) are you using?
