August 3, 2015 - 10:18pm #1

Hi, i am new and i was creating AR project for my final college assignment. I'm using Unity 4.6.2 and Vuforia, i faced the problem when i implemented it to my Samsung GT S-6810 Jelly Bean and Motorola and it only show black screen after the splash image. I set the 32 & 24 bit display buffer uncheck but nothing change.

Before, i created AR project used Vuforia 4.2.3 and everything worked well on my phone, though i need to updgared it to vuforia 5 because i need the VirtualButton Samples which did'nt release anymore for 4.2.3 version.

Please please help

I am with this same issue... I tested my app on Samsung SII and S4 with no problem, but in Samsung Galaxy Gran Duos and J8, I got black screen... why?!

 

I noticed that it happened after I changed AR Camera World center mode to DEVICE TRACKING. Since then, I returned with this issue reports by some users.

 

I already changed Graphics API to Open GLES2, Rendering path to Legacy deferred, downloaded the latest JDK, built on 32 and 64 bit and NOTHING! Same issue...

 

I don't know what to do anymore... does anyone can help me?

HI :) : i want to share my case LOOK:

I got the black screen, some post say you should delete the vuforia.jar and the vuforiaUnityPlayer.jar on Plugins/Android (because the android SDK JAR crash)..... DONT DO THAT your androids will be copiled but when you start the app it will go to black.

SOLUTION:

Download a new oracle JAVA SDK 8 for windows 86 bit (32 BITS) change the java sdk on your unity 5 file for the new one

 

IT WORKS FOR ME.... hope this can be usseful for some one else :)

I see you are using Unity 64bit but as far as I know, vuforia still works only with Unity 32bits on windows plataform.

Hey guys,

 

maybe someone can still help me!

 

I am developing using Unity5.3.5f1 (64 Bit) and have the same problem with the black screen on my Nexus 7 Android version 4.4.3.

I tryed every solution for the player settings mentioned here but nothing worked!

I try to implement the Vuforia Object Recognition Unity Sample (https://developer.vuforia.com/library//articles/Training/Vuforia-Object-Recognition-Unity-Sample-Guide)

 

I have no idea how to fix this problem! :(

 

Thanks for your help!

Hi,

I had the same problem, using Unity 5.1.2f1 32 bits, and vuforia 5. You should also check that in Other Settings for Android, Rendering, not only Rendering path should be set to Legacy Deferred, but also uncheck Automatic Graphics API and just leave OpenGLES2. I had here OpenGLES2 and OpenGLES3 and removing the last one made my project work.

I also tried with Rendering path set to Forward and the app still worked.

I'm very happy to hear you finally got things working. It took me some time to figure it out myself.

The software is great and you can do a lot of fun things with it, but I wish they had a team dedicated to keeping up with Unity's changes, and updating their documentation, so new developers don't have to spend so much time trying to setup.

But at least you can enjoy the software now..

Happly Developing! ^_^

Setting the minimum supported Android platform version to Android 4.0.3 fixed the issue, along with setting the Rendering Path to Legacy Deferred(light prepass) to show the 3D Object in the sample's scene.

I tried getting my Samsung Note 4 to work with the Background Texture Access Samply Unity Project, but the device only shows a black background with a flickering white triangle. I am also working on my own project which is showing a flickering red triangle on a blank background when I try using the ARCamera. The ARCamera is working fine in the editor.

Should I use a different version of the Unity Vuforia SDK? or what are my options to get this working on an Android device? Thank you for the help.

I am currently using Unity 5.1.2p3 (32 bit) with the latest Vuforia Unity SDK.

Check the logs to see if there is any error message. Maybe you are forgetting to use a license key. Is this happening with the sample apps we provide?
