I've taken a look at the Android SDK: it seems the java.lang and 
java.util namespaces and their classes are available so it might be 
rather simple to get an Android application compiling and running.

But for now I have the problem to convert the class files provided by 
the SDK into Pascal units using javapp. I have unpacked the android.jar 
to $somedir/android and also copied javapp.jar there (just to be sure 
that there are no path problems ^^). I cd'd into that directory and 
issued the following command to convert the android.app namespace:

java -jar javapp.jar -protected javapp.jar android.app.

The output is the following:

default charset: UTF-8
Determining short Pascal class names...
Indexing classes under android/app/Activity...
Indexing classes under javapp/jar...
Printing classes...

The result is a "java.pas" and a "java.inc". The first includes the 
latter and the latter is empty.

So what am I doing wrong? (The same happens if I try to use the 
android.jar instead)
