Android, Ubuntu, and the JDK

[Richard Gaskin]

Many thanks to RunRev for providing Android build support in LiveCode 
for Linux.

I was looking forward to trying that last night, but ran into a snag:

I've installed the Android SDK, with a minimum version support of 2.2. 
I've also installed OpenJDK for Java 6, and that much seems to be working.

But when setting up LiveCode's Prefs window I can select the SDK folder 
without issue, but pointing it to my JDK folder alerts me that it's "not 
a valid JDK", with no further details.

What exactly is it looking for?

Have any of you been able to successfully set up Android building from 
LC 5.5.2 under Ubuntu?

TIA -
