Getting AssetManager pointer from AAssetManager_fromJava (Android Qt6.9.1)

[SMF-Qt]

I was given this code to access the Android asset manager, I think the "activity.object<jobject>()" is wrong because when I run the App it errors:

QJniEnvironment env;
QJniObject activity;
if (env.isValid())
{
    activity = QJniObject::callStaticObjectMethod("org/qtproject/qt/android/QtNative", "activity", "()Landroid/app/Activity;");
    if (activity.isValid())
    {
        assetManager = AAssetManager_fromJava(env.jniEnv(), activity.object<jobject>());
    }
}

Running the app gives the following error:

F/.home.QtTest: runtime.cc:716] JNI DETECTED ERROR IN APPLICATION: jfieldID long android.content.res.AssetManager.mObject not valid for an object of class org.qtproject.qt.android.bindings.QtActivity
F/.home.QtTest: runtime.cc:716]     in call to GetLongField
F/.home.QtTest: runtime.cc:716]     from void org.qtproject.qt.android.QtNative.startQtApplication()

Can anyone suggest a correct value?
