I am new to Unity and VR. I am trying to create a very basic VR application using Unity and my Android phone via Google Cardboard.
I followed the steps given here, https://developers.google.com/cardboard/develop/unity/quickstart, https://docs.unity3d.com/Manual/android-sdksetup.html and installed android studio sdk on my laptop.
Here is my scene, hierarchy, and build settings. No error while building. The refrigerator model is my game object, and as you can see the camera points at the refrigerator, at least that's what I inferred.
On my phone, I only see the green background when facing down, as I turn my phone up it changes into white. Nothing else is seen.

Make sure the HelloCardboard scene is included when building your app, and remove the default empty scene which just contains an extra redundant camera.
You have to do that from the Build Settings window with the button "Add Open Scenes".

So, my game in the windows build works perfectly but it freezes in my android build when my gamescene is finally loaded. It's a network game so I can see my android player moving, it's just that the screen it's permanently frozen. I have no errors in console and in one of my build I managed to get this: not sure if it helps, not sure what to do

Use Vulkan API for Android - instead of GLES: https://docs.unity3d.com/Manual/GraphicsAPIs.html
I'm trying to run through the instructions or the basic demo here: https://learn.microsoft.com/en-us/azure/spatial-anchors/quickstarts/get-started-unity-android Everything seems to go fine however when running the app on my Galaxy S8+, the script seems to go no further than displaying the message 'Tap a surface to add the Local Anchor' with a Next Step button below. No amount of tapping gets me further.
The camera is working.
I'm using Unity 2018.3.11f1
ARCore 1.50 as indicated in the instructions.
I've also tried exporting and building in Android studio and deploying and still nothing. I did make sure I had ARCore Supported selected in the Player Settings --> XR Settings
Anyone else encounter this?
I am developing using Unity5.3.5f1 (64 Bit) and have a problem with a black screen on my Nexus 7 Android version 4.4.3 every time I try to launch the app.
I try to implement the Vuforia Object Recognition Unity Sample (https://developer.vuforia.com/library//articles/Training/Vuforia-Object-Recognition-Unity-Sample-Guide) so it should work while I followed the instructions.
I didn't modify the code, just followed the instructions to add the 3D target.
I followed the hints of the developer forum to set the player settings for building https://developer.vuforia.com/forum/issues-and-bugs/camera-not-working-when-app-installed-mobile but nothing changed the situation:
Setting Rendering Path to "Legacy Deffer"
changing the Minimum API Level to Android 4.2
enable "GPU skinning"
set graphics APIs to "OpenGLES2"
I have noticed a lot of problems between unity and mobile devices when building. There seems to be some residual meta data left on the device from unity so not all changes end up working properly (which holds the information of what objects the script is attached to). I had an instance where I deleted EVERYTHING in my scene and I had a debug script attached to some of those items that would output some text to the Xcode console in the scripts start() method. After cleaning out the entire scene and redeploying that debug script was sill outputting to the console. I deleted the .meta file associated with that script and redeployed. This deletion stopped the file from running. I have noticed that restarting the device can also fix this issue. Also deleting the meta, deploying, then undoing the delete and running again also fixes some of these issues. You will NOT notice this problem when developing in unity and breakpoints will never be hit, but it will still happen on the mobile device and even run scripts that you completely disabled.
I've been working on an AR application using unity3d with vuforia
whenever a marker is detected (image) it must show a specific 3d model related to that image
It works totally perfect in unity but when I export the app as .apk and run it on my android device, models don't appear, although it detects the marker I checked that by printing out a specific sentence related to each marker
I also tried before to load some models from the unity assets and it also worked fine and appeared on my android device
I'm using 3ds models each one is about 23 MB size
I thought it might be because of the size of app so I tried to place only one model but that didn't work either..
any solutions for that?
I created a new Unity Project which just has a simple Main camera and a Directional Light. I added the scene and chose Android as my build environment. When I "Build and Run" my Unity app always crashes and does not start the game. I tried building the same apk on other (non-tango) android device and it seems to load fine. I haven't even added my Tango prefabs yet (although i did try adding them but no luck).
Am I missing something ? Has anyone else experienced this problem ?
P.S.: My other tango unity samples seem to run fine.
Try following the steps in https://developers.google.com/project-tango/apis/unity/unity-prefab-motion-tracking. They also have some suggested Player Settings for Default Orientation (Landscape Left) and Min API (17).
Try disabling "Dynamic Batching" in android player settings and disable "Draw Default UX Exceptions" in Tango Ux Script, which did the trick for me
