Yes. And luckly it works in all devices =) I was a bit scared that I
might hit a wierd problem here involving code generation or whatever,
but ... just a normal typo in my program.

See here:

http://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/bindings/android-ndk/

The file jni.pas is what you are looking for. The rest are Android NDK
headers. I think that it should work for any Java platform.

In the folder "examples" there, there is a full Android JNI example.

In lazarus/lcl/interfaces/customdrawn/* there is also a lot of JNI
code for Android which can be utilized as examples to learn how to use
JNI.
