Black screen android unity build

Hello,

So I have a unity project in which I dragged a WikitudeCamera (deleted the original one that comes with a scene) and and ImageTracker. That's all there is in the scene. If I run it in unity with a webcam, it works perfectly. The image gets detected and the model gets show accordingly. But when I build for Android using my phone, I only get a black screen and nothing else.

Building and running the main menu scene from the example scenes does work. But only when I go from Menu Scene to any other scene, only then it works. If I build any example scene seperately, I get the same result. A black screen,

I have looked around on the forum trying to find a solution, but so far I haven't found one that works.

I finally managed to fix it and is running on my Android device.

I am not sure if it was a wikitude or unity problem. I started with a new project and imported the wikitude package at the beginning, but I had to make some changes on the script of the ManifestAR and ContinuousRecognitionController files in order to work. 

Hello,


I am also facing the same problem. I dragged a WikitudeCamera (deleted the original one that comes with a scene) and and ImageTracker. That's all there is in the scene. If I run it in unity with a webcam, it works. But when I build and run for my Android phone, I only get a black screen along with Wikitude logo and nothing else.

You have to give permission to your camera in the AndroidManifest.xml file.

<uses-permission android:name="android.permission.CAMERA" />

<uses-feature android:name="android.hardware.camera" android:required="true" />

These 2 permissions were already there in the AndroidManifest.xml.

It's been a while since I did it. Sorry... 

In my start scene I created an empty game object and attached this script on it. So when I start my app for the first time it asks for permission.

Hope this works...

@elli karyati. Thank you. The camera is now working.

To avoid Black Screen problem, I had to give camera permission manually (on android) after the Wikitude-AR based app get installed.

Hi,

I have a black screen when I build a scene to an Android 10/ Unity 2018.4.27f1

Can anybody help?

Hi,


did you make sure to follow the details mentioned in this stream and other forum posts related to a black screen in combination with Unity? Please also check the setup and getting started guide in our Unity documentation to ensure that all steps are followed as required.


Thx and greetings

Nicola
