If you don't mind a 3rd party app, you could try Arc2Earth Sync
It will connect to Fusion Tables on your account's behalf and make it look like an ArcGIS Feature service. It can also use your ArcGIS.com credentials to create/update web maps so your FT tables show up automatically in the ArcGIS iOS/Android apps (or any of the ArcGIS Online apps/apis).
Check out the sample here. And here's the same data used on Google Maps directly from the Fusion Table
We've got a big update coming out soon too. Image tiles, vector tiles, UTF grids are all automatically created/updated when your data changes and then hosted for you (or move the caches wherever you like). New providers for Fulcrum, CartoDB and plain ole local shapefiles make it really easy to get started and work with your data in ArcGIS Online.
