Unity 5 after publish, android scene appears empty

Question

I'm working on a school project and we are building a game for Google Cardboard using Unity 5. I have all the drivers, SDK, and JDK files I need and I can play the game in editor and it will appear on my phone via the Unity Remote 4 app. It has terrible fps (less than 10, I'd guess) but that's not even my question.

I tried publishing the project and moving it to my phone to see if that would help with frame rate. Instead, I got a blue screen. Blue like an empty unity scene. I can still see the cardboard outline interface so I know that objects are still in the scene but I can't see anything.

Answer 1

I don't know if this can help you (without any further information) but you could try these options

• turn off Cardboard.SDK.nativeDistortionCorrection: to make Unity draw directly to the screen.

• Edit Cardboard.CreateStereoScreen() and change the settings.

Answer 4

I had a problem with a blue screen on Android devices which sounds similar to this one. From what I found out it may happen that some Start() callbacks are not called correctly on Android in the startup scene. If nothing happens but the camera is active it only renders a blue background screen. This happens only very sporadically.

There are two things you can try:

1. Create an "empty" startup scene which only loads your actual scene.

2. Use not only Start() but also OnEnable() for backup.

Answer 5

Make sure you hit "Add Open Scenes" in Build Settings such that all you scenes are added to the build. This was the solution for my case.

Answer 6

I have resolved my issue for Google cardboard by these steps.

Edit -> Project settings -> Player -> Other settings -> Graphics APi

And remove Vulkan from the list by clicking - at the right bottom of the box.
