I was able to load a device parameters through the url from Unity.
URL: "https://arvr.google.com/cardboard/download/?p=Cgxtb2JmaXNoIEdtYkgSElZJU0lUIFBMQVlFUjM2MC5ERR2ZuxY9JbbzfT0qEAAASEIAAEhCAABIQgAASEJYADUpXA89OgiCc4Y-MCqJPlAAYAA"

Please check the screenshots and let me know if the parameters loaded are right:

Yes, the name is correct at least.

It seems that the url is changed. But it doesn't matter, any kind of url will do. Is that just default cardboard profile? or will it override current cardboard profile?

For now it loads the default profile at start, hence overrides the saved profile. I am working on loading the default profile only when there is no saved profile.

Thanks. If possible, provide both possibilities, one is set default profile, another is set current profile.

Will do that. Thanks.

@cai-mobfish
The implementation is complete. Function to load device parameters from URL is 'LoadDeviceParametersFromURL' in 'CardboardQrCode.cs'.

I have created provision to load default device parameters (in 'CardboardMainCamera.cs') when one is not available.
Changes are pushed to branch 'DeviceProfileFromURL'.

@rohantipare Thanks for the implementation. I have yet tested on my side, but I have a question:

I noticed that you added a header file directly in Plugin folder, which already exist in Cardboard SDK. How does it work without implementation file in Unity?

@cai-mobfish
I did not found a way to make the 'device_param_helper.h' accessible to the utility native file. It fails to build if that file is not included. I am looking for the solution.

@rohantipare I see. I didn't mean it's not good, it's just a question. It's fine if it works with Build. I'll do some test later today.

@rohantipare I just checked your code and tested, code works. And I have some additional questions:

• I noticed libsdk.a is modified, please post here which file and what code have changed?
• I noticed that set this kind of url parameters also works offline, and the paramater in the url is the base64 text of protocol-buffer-encoded parameter. Is the full url needed?
• If I have a short link like this "https://goo.gl/tcRG0r", is it also able to decode with Internet?

And please do these changes:

• Merge from public-dev, I did some change today, added feature vr and no-vr camera.
• With this change, I think the part of logic "scan camera when profile unavailable" will no longer needed. I also noticed that there is a method in object-c, saveCardboardV1Params. It seems that when I skip the camera scan when no profile available, cardboard sdk will set a default value, can we also use that when profile is not available? If not, we should extract default cardboard v1 parameter and do on our own, please post the default cardboard v1 url here if this is the case.
• Invoke("LoadDefaultProfile", 1f); I noticed you write this. Try to load default profile without any coroutine or delay method. Also, put them in CardboardQrCode. If it's really impossible, please explain here why and leave this part to me if it can be solved in unity c# code.

@cai-mobfish
1: 'libsdk.a' - I was trying to expose the 'device_param_helper.h' file in the libsdk.a to make it accessible for the native code, but it didnt work. I will reset it previous version.
2: 'short url' - It should work with short url. I will confirm it. The Failure case needs to be handled in case of connectivity issues.
3: 'cardboard v1' - I will look into it.
4: Invoke("LoadDefaultProfile", 1f) - I was not able to call this function from Awake or Start, as not all callbacks/listeners for 'parameter change'; would be listening. This leads to incomplete execution of device parameter updation.

@cai-mobfish
I have pushed the merged branch of 'ParmetersFromURL'
I have tested the short URL, it works.

@cai-mobfish
I have found the URL for cardboard v1 parameters.
http://g.co/cardboard

I did some refactor and modification in new branch, and merged into public-dev.

Default cardboard profile will be set when app is initially started. Change profile in script can be done in any time, and will overwrite current profile.
