I've developed a new little tool which will check what versions of the Android SDK and API levels are installed and also where those directories are. It will also check what version of Java (SDK) you have installed. It should help with some users who seem to struggle installing the correct versions and ensuring the correct API levels are on etc.
It is still technically a BETA, so if you see any weird messages, or things not working correctly, shoot me a screenshot here and I'll check it out.
Does not work with the Free Edition. You should be able to access this under the 'Tools' menu inside Fusion 2.5 once installed.
