You forgot the result. The items key is in the result.

I'm sure there are more elegant ways of doing this, but this seems to work...

Create 2 empty game objects and name them Cam1 and Cam2. Add a camera game object to both. Settings for cameras.

Camera 1 (foreground): Depth: 1 Clear flag: Depth only

Camera 2 (background): Depth: 0 Clear Flag: Solid Color

Now just point camera 1 at the stuff you want in the foreground and point camera 2 at the background or whatever configuration you want.

Considering Java is pass-by-value, we know that Java isn't passing the object, it's passing a reference to the object.

Because of this, when you did CardBoard c3 = c1.go(c2);, the method go(Cardboard cb) just copied the reference value of c2 to cb and therefore c2 is unharmed by the cb = null;. So, c2 is not eligible for GC.

c3 never gets to be constructed as an object, it is just a variable of type CardBoard initialized to null. Thus, it cannot be garbage collected because it is not even created on the heap.

The ItemsDB constructor used when the activity is started calls fillItemsDB() which adds items to the ItemsDB field. However, that field is not initialized in this constructor.

You need to either initialize it there, call the other constructor, or initialize where you declare the field.

Your browser is probably just caching the image response from cataas.com.

Per the answers to this SO question, you can just tack on some harmless GET parameters to the request URL that will be ignored by the server but ultimately trick your browser into not caching the response:

Should I take into account the framerate dependency and multiply the distance to Time.deltaTime or this distance is framerate independent?

No because:

1. you already know the original and new positions
2. distance calculations doesn't involve time even during instantaneous calculations

Frame rate or more importantly time since last update impacts when you are calculating a new position based on velocity. In this case time since last update is used as a scalar.

By the way the line

Try the following. It will check only if there is a period near the end, and it will remove the extra quotation marks and comma that you remove in between your test and output case, but will not remove extra characters.

I haven't found a solution to work around the problem, so I decided to do without VR plugins completely, i.e. no XR management plugin and no G-Cardboard XR plugin.

My solution: I have created two independent cameras, which are combined by the father object and thus form the main camera. Then I assigned a script to the parent object of the main camera, which reads the gyroscope data from my iPhone and thus adjusts the rotation of the camera.
