How get result from system activity? ( ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION )

Compozitor

There is a task to copy files from application resources to the device for further work with them when the application is launched.

When the application is launched, I launch an activity that asks to grant the application the right to access all files.
I manually grant the application this right, but for reasons unknown to me, the application, having received permission, does not copy files to the device, but does this only when the application is launched again.

And I wanted to track the result of the activity using the result class inherited from QAndroidActivityResultReceiver, the reference to which is specified in the call QtAndroid::startActivity(intent, 118, &result) but analyzing the execution of the program, I conclude that the void handleActivityResult(int receiverRequestCode, int resultCode, const QAndroidJniObject &data) method was not called when working with the activity.

And finally, a question: Why does the activity that asks to grant the application access rights to all files not give any results in the method handleActivityResult(int receiverRequestCode, int resultCode, const QAndroidJniObject &data)?

It seems that this method is simply not called.

ActivityResult result;

jboolean value = QAndroidJniObject::callStaticMethod<jboolean>("android/os/Environment", "isExternalStorageManager");
    if (value == false)
    {
      // Get packege name (exemple: "package:org.appname.test")
      QAndroidJniObject activity = QtAndroid::androidActivity();
      QAndroidJniObject context = activity.callObjectMethod("getApplicationContext", "()Landroid/content/Context;");
      QAndroidJniObject packageName = context.callObjectMethod("getPackageName", "()Ljava/lang/String;");
      QString sPackageName = "package:"+packageName.toString();

      // Get permission to access all files
      QAndroidJniObject ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION = QAndroidJniObject::getStaticObjectField( "android/provider/Settings", "ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION","Ljava/lang/String;" );
      QAndroidJniObject intent("android/content/Intent", "(Ljava/lang/String;)V", ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION.object());
      QAndroidJniObject jniPath = QAndroidJniObject::fromString(sPackageName);
      QAndroidJniObject jniUri = QAndroidJniObject::callStaticObjectMethod("android/net/Uri", "parse", "(Ljava/lang/String;)Landroid/net/Uri;", jniPath.object<jstring>());
      QAndroidJniObject jniResult = intent.callObjectMethod("setData", "(Landroid/net/Uri;)Landroid/content/Intent;", jniUri.object<jobject>() );


      QtAndroid::startActivity(intent, 118, &result);

    value = QAndroidJniObject::callStaticMethod<jboolean>("android/os/Environment", "isExternalStorageManager");
    if (value == true)
    {
      // Copying files
      
    }

File activity_result.h
