How to call JAVA method that returns a String?

[lqsa]

I would like to call a JAVA method that is in my QtActivity that return a string.

I've tried these, but all gives me a compilation error:

jstring value = QtAndroid::androidActivity().callMethod<jstring>("getUser", "()Ljava/lang/String;");

jstring value = QtAndroid::androidActivity().callMethod<jstring>("getUser");

error: undefined reference to '_jstring* QAndroidJniObject::callMethod<_jstring*>(char const*, char const*, ...) const'

I found it!

    QAndroidJniObject juser = QtAndroid::androidActivity().callObjectMethod("getUser", "()Ljava/lang/String;");
    QString user = juser.toString();

Thanks for the tip. The problem was callMethod vs callObjectMethod. I think callObjectMethod is for functions that return L types (classes) and the former for primitive types.

Thanks
