So, for whatever reason the camera on my unity project build on android is black. I don't believe this is a coding issue considering the fact that it works perfectly fine on my pc with a normal webcam. I'm using unity 2021.1.0f1.
I figured it out. Turns out all I had to do was go into settings and turn on the camera permissions/restart the app. Even though I already allowed it in the app, guess it caused an error when a camera wasn't detected straight away.

After creating a demo project, I have exported a game project for my Android device and as the game played within the device, I got shocked because of this kind of output:
There is no Canvas UI exists, there is no skybox exist and there is a black stripe in the middle of the screen.
Up to now, I have tested game within the Unity Editor and it was working perfectly.
Here are the inspector settings for the Android Build:
Now provide me some suggestions so I can solve this problem and I can test the game within my Android device.
Now I got a solution for my this problem. I was getting this kind of error messages in the console:
There is a shader compiler related problem that exists and I got a proper solution in this thread and I have applied and it worked for me.

I've built the app and compiled it with VR enabled and cardboard selected as my VR device. I can install and run it on my phone (Samsung S8) BUT the in game camera is stuck in portrait mode and the yew is inverted (turning my head left turns the camera right). I have scoured the internet but still can't find a way to fix this.
I've enabled VR in playersettings and added google cardboard as my VR.
I've also disabled portrait views under orientation.
I've set the camera as both a child and parent object.
I've built the app with both cardboard and daydream selected as the VR (and each individually) but still the same issue.
I've tried forcing different higher levels of API requirement
I have added and removed GvrEditorEmulator from the project and the GvrControllerMain and no luck.
I've even flipped the camera manually by a 180 degrees and this made the view be in landscape but in this case the pitch was inverted (when I look up the camera looks down) and I haven't found a way to resolve this.
In the editor view the screen looks fine, but every time I run it on my Android phone it force starts in portrait mode and the pitch or yew is inverted.
Is there a hidden option I need to switch, does anybody have more suggestions that I could try?
You can see what the app looks like when I hold the phone i portrait mode on the link bellow (the image breaks when I try to add it to the post for some reason).

Its worth mentioning that I'm working with Unity version 2019 2.0b2 because any other version I tried would not detect my installed Android SDK and would not let me build the project. I've tried on multiple machines and always had that problem so I'm afraid of attempting an upgrade to a newer version would break my build ability.
This seems to be a known and reported issue for Google VR SDK for unity. Its been reported on their github page.
The only possible fix is reverting back to Unity 2018.3.14f1. I did this by exporting my v2019 project, then creating a new 2018.3.14f1 version project and importing the original into it. This rebuilds the project and should avoid conflicts if you're lucky.
I setup the Google VR SDK in 5.6Beta Unity, everything works out smoothly. I click on the demo scene and on the play button for the first time, I got this weird stereo rendering in my game view. Anyone have any idea how to fix this?
Here is the Official fix until the next release of gvr.

I'd say the value I have to change is the stereoMultiplier of the StereoController script attached to the main camera. Anyway I think I have changed every single value of GvrViewer, MainCamera and StereoController. Nothing seems to change the separation of the left and right cameras when compiled to the Android smartphone.
I can see a correct separation in the Unity Game View, but when I compile it to the smartphone, the cameras are too separated (see image below).
I think this issue has happened after updating the Smartphone to Android 6.0 Marshmallow (CyanogenMod 13.0), on Samsung S4.
UPDATE: I have updated to GoogleVR 1.0.1. The same problem is still happening.
Changing scale to 0.007 (which is a very similar scale to the objects in the provided demo scene of GoogleVR: 0.003) seems to fix the problem.
Note: discussed here: https://github.com/googlevr/gvr-unity-sdk/issues/351
UPDATE: in the previous link, somebody wrote:
Android app:
/sdcard/Cardboard/current_device_params
all gvr(cardboard) app will use this file --- "current_device_params".
maybe you should go the url to setup your device profile https://vr.google.com/cardboard/viewerprofilegenerator/

So, I made my game for Android device and I've got a menu, store, info scene and a main scene. The main scene is where I play the game. But when I hit start on the menu it loads the "MainScene" and all I can see is the GUI but nothing else. I can collect items but the scene is just black (except the GUI).
I tested out with a web player and everything was fine then changed to Android and after I installed it (several times) I looked at the black screen.
How to fix this?
(I'm using Unity 4.6.1)
Can't comment, not enough rep.
Anyway, there are lot of things that can cause a black screen to happen on Android. Here are a few to look at -
Be sure your camera is not getting deactivated (in your case maybe not).
Are you using any plugin that is using alpha channel or stencil buffer?
Any other plugin that may causing this, disable them to check.
Is your 24/32 bit buffer ticked/not on build settings?
Double check your camera settings, lighting.
Stripping level to disable and rendering path on build settings etc.
Check the game on another device.
Provide more info about the scene here
There's definitely something on that specific scene.
