I'm no expert and am not a programmer, but I believe Android apps *are* programmed in Java. I know the SDK is full of jar files.

OK, guess there is a way to run Java on Android. I was confused as there
are Java programs for Internet Chess Club that run on the Android phone and
I thought a Java program came as a Jar and so clearly there is something
different here?

Android apps are coded using Java, but they run in the Dalvik VM in
Android, which is different from the Sun Java VM on PCs

It would be interesting to know about the Android version development. Since
Pimlical was created in Java and there is no Java virtual machine on Android
I assume that there is a compiler that compiles Java source for Android
target and links all the needed things. Sort of like a Windows native would
have been.

Yes, google provides all the necessary components to run in Eclipse. The
Android version of PImlical is of course in Java, but you are quite correct
that Android phones do not have a JVM. They do implement most of the Java
classes, but in a typically stupid NIH fashion, fail to implement some basic
classes, and then implement some JVM classes but in a DIFFERENT manner. For
example, there is no Dimension class - rectangles are handled differently,
and for absolutely NO GOOD reason. This was unexpected as it meant a lot of
time wasted on dealing with incompatible serialization issues.

It has certinaly been immensely frustrating (not to mention hugely
time-wasting) to deal with all these totally unnecessary differences. Young
programmers still completely fail to understand the importance of standards
and feel that it's always better to "improve" things constantly, when such
"improvements" waste millinons of $'s and whatever slight benefit the
improvement brings is overwhelmed by confusion and incompatibility </rant>

Anyway, Eclipse is quite a nice environment to work in and debugging on the
Phone is not too bad, except for some very annoying bugs in Eclipse which
really should have been fixed a long time ago.

Cheers!

Right about standards you are. Has using Java saved time or wouldst have been better to have source in multiple languages? I suspect you are ahead with Java but not nearly as much as you expected. I think Java has not lived up to the original dream.

The original dream was write once, run anywhere. But they left out the
Gotcha - debug everywhere.

Yes. Many tens of thousands of lines of code transported into the Android
environment without modification. The problem was not the language per se,
but the different architecture, that went to the core of how the program was
put together. That was the biggest issue.

Expectation-wise, Java did fine - what I wasn't anticipating was that in
Android, Google changed things for no apparent good reason....
