You have to pass "-classpath path/to/android.jar" (or "-classpath ." if you extracted android.jar in the current directory) as parameter to javapp (not as parameter to java!). I've added this fact to http://wiki.freepascal.org/FPC_JVM/Building#Building_javapp

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