This will sadly not solve my problem. The GPGME interface is not the interface we would
like to use for our purposes, because not all of the GPGME features should be available 
in our framework (intentionally). Therefore I would have to write (actually I already wrote, 
beside the callback problem) a C++ wrapper for GPGME. And I would have to write another 
wrapper for the Java wrapper, for the same reason. The combination of this would lead to 
maintaining at least two wrappers: the one for Java and the one for C++. Moreover the 
license is GPL and we would need LGPG. Maybe this point could be solved with separate 
license negotiations. But for now I guess I'm back to my question: What would happen if 
I would rely on pinentry in android?
