RvJNIHelper

Helper classes to load java classes in an Qt project thru JNI.

This helper was created a long time ago with pure C++. I started to port this to Qt.

The idea is to make java calls easily in Qt:

RvJVMHelper* h = new RvJVMHelper(QString("."));

RvJVMObject *obj = h->createObject("Test");
obj->callMethod("m"); //void method. No parameters

int *ret = (int *) obj->callMethod("sum", "(II)I", 10, 20); 

qDebug() << (QString("%1").arg(*ret));
delete ret;

obj->callMethod("printName", "(Ljava.lang.String;)V", "Teste de nova String via C++");

char *str = (char *) obj->callMethod("returnName", "(I)Ljava.lang.String;", 10);

qDebug() << str;

delete str;

At signature names, I've used different approach (using java.lang.String instead of java/lang/String) to make calls more close to Java use.

Qt has a module named QAndroidExtras. But it's no compiled for Desktop andit's using Qt private headers (qjni.h).
