Can’t create java class by QAndroidJniObject

[stereoMatching]

Try to create a java class from c++ side but keep crashing

appBucksAdv.java

package adv;
 
    import org.qtproject.qt5.android.bindings.QtApplication;
    import org.qtproject.qt5.android.bindings.QtActivity;
 
    import android.os.Bundle;
 
    public class appBucksAdv extends QtActivity
    {    
    }

package adv;
     
    import org.qtproject.qt5.android.bindings.QtApplication;
    import org.qtproject.qt5.android.bindings.QtActivity;
     
    import android.os.Bundle;
     
    public class appBucksAdv extends QtActivity
    {    
    }
