It appears that the new Zeam version 2.9.2 requires Android 2.2 and up.
Starting at Zeam version 2.9.0 it was compiled in API level 8 which is 2.2 .
If you follow this link at xdadevelopers it appears that Zeam 2.8.8 is available as a download apk which might still be for 2.1 .
On my rooted NC it is Zeam 2.8.7
