How do I return bool from Android Java code?

Allstar12345

I'm new to Android and JNI stuff, I basically need to return a boolean from some android java code,

Now looking at an example I can get a string to return but not sure how to go about returning a bool

Currently have test.java:

    import org.qtproject.qt5.android.bindings.QtApplication;
    import org.qtproject.qt5.android.bindings.QtActivity;
    import android.content.res.Configuration;
 
    public class test extends QtActivity
    {    


    public static String printBob(int a)
    {
      return "hello bob";
    }

public boolean teste(){

    Configuration config = getResources().getConfiguration();
    return config.isScreenRound();

    };

    }

Now the printBob() works fine from:

QAndroidJniObject str = QAndroidJniObject::callStaticObjectMethod("test",
                                       "printBob",
                                       "(I)Ljava/lang/String;"
                                       );

    return str.toString();

But I'm not sure how to call the teste() function to return the bool

Thanks

@koahnig I read that initially, the signature for string is of course

(I)Ljava/lang/String;

I get that bit, but whatever i put in the last argument fails, I'm new to this stuff it doesn't really make sense


    QAndroidJniObject str = QAndroidJniObject::callStaticObjectMethod("test",
                                           "teste",
                                           "(I)Z");

@Allstar12345 You have to use full name, with package.
For example if your class test is in package com.mycompany.application:

 QAndroidJniObject str = QAndroidJniObject::callStaticObjectMethod("com/mycompany/application/test",
                                           "teste",
                                           "(I)Z");
