如何通过Qt从android打开位置设置？

我已经尝试了这个，我可以成功打开设置，但不能打开位置设置：

QAndroidJniObject intent("android/content/Intent","()V");
    if ( intent.isValid() )
    {
        QAndroidJniObject param1 = QAndroidJniObject::fromString("com.android.settings");
        QAndroidJniObject param2 = QAndroidJniObject::fromString("com.android.settings.Settings");

        if ( param1.isValid() && param2.isValid() )
        {
            intent.callObjectMethod("setClassName","(Ljava/lang/String;Ljava/lang/String;)Landroid/content/Intent;",param1.object<jobject>(),param2.object<jobject>());

            activity.callObjectMethod("startActivity","(Landroid/content/Intent;)V",intent.object<jobject>());
        }
    }

我甚至已经将param2更改为＆＃34; android.settings.LOCATION_SOURCE_SETTINGS＆＃34;因为它写在Android Developer页面上 - 但没有任何成功。

有人知道怎么做吗？谢谢！

我找到了解决方案！

QAndroidJniObject activity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");
if ( activity.isValid() )
{
    qDebug() << "activity.isValid()";
    QAndroidJniObject param = QAndroidJniObject::fromString("android.settings.LOCATION_SOURCE_SETTINGS");

    if (param.isValid() )
    {
        QAndroidJniObject intent("android/content/Intent","(Ljava/lang/String;)V", param.object<jstring>());
        activity.callObjectMethod("startActivity","(Landroid/content/Intent;)V",intent.object<jobject>());
    }
}

QAndroidJniObject activity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");
if ( activity.isValid() )
{
     QAndroidJniObject param = QAndroidJniObject::fromString("android.settings.LOCATION_SOURCE_SETTINGS");

     if (param.isValid() )
     {
           QAndroidJniObject intent("android/content/Intent","(Ljava/lang/String;)V", param.object<jstring>());
           activity.callMethod<void>("startActivity","(Landroid/content/Intent;)V", intent.object<jobject>());
     }
 }
