Augmented Images: Not being able to add images runtime when using Instant Preview

[patrickdemooij9]

SPECIFIC ISSUE ENCOUNTERED

Currently I can't add augmented images to the augmented images database. I currently wait until the session is tracking and then try to add the image so the augmented database located in the session config the following way: session.SessionConfig.AugmentedImageDatabase.AddImage("TestImage", testTexture);

testTexture is a Texture2D that is the same as image 001 from the example. The texture has read/write enabled and uses RGB 24 bit for formatting.

I have tried the following things:

• Adding the images on an empty image database.
• Creating the image database myself with ScriptableObject.Instantiate and then adding the image to it.
• Waiting 5 seconds after the session is tracking and then adding the image.

None of the above work for me. I also made a new project, thinking that maybe I messed with some configurations, but I am able to recreate the problem.

Error:

VERSIONS USED

• Unity: 2018.3.0f2
• ARCore SDK for Unity: 1.6
• Device manufacturer, model, and O/S: Editor
• ARCore: 1.7.190128146 On Windows, use: adb shell pm dump com.google.ar.core | findstr /i "packages: versionName" On macOS, use: adb shell pm dump com.google.ar.core | egrep -i versionName\|packages:
• Output of adb shell getprop ro.build.fingerprint: samsung/dreamltexx/dreamlte:8.0.0/R16NW/G950FXXS4CRLC:user/release-keys

STEPS TO REPRODUCE THE ISSUE

1. Create a new project with the versions specified above
2. Open the AugmentedImages example
3. Open the ExampleController
4. Add the following code with the other variables:

private bool addedNewDatabase; [SerializeField] private Texture2D testTexture;

5. Add the following code in the update after the check for if the application is tracking.

if (!addedNewDatabase)
            {
                ARCoreSession session = FindObjectOfType<ARCoreSession>();
                //session.SessionConfig.AugmentedImageDatabase = ScriptableObject.CreateInstance<AugmentedImageDatabase>();
                session.SessionConfig.AugmentedImageDatabase.AddImage("TestImage", testTexture);
                addedNewDatabase = true;
                return;
            }

6. Add the 001 example texture to the inspector for the testTexture. Enable the write/read attribute and use the RGB 24 bit formatting. It will give another error otherwise
7. Run the application, it will give an error in the editor window.

I am facing the same issue when i try to do it in editor, but it works well after building to an android device

[patrickdemooij9]

Just tried to make this work again, but it seems like it isn't an Instant Preview only problem. I debugged the whole code while on the android mobile and it doesn't return anything from "nativeSession.AugmentedImageDatabaseApi.AddImageAtRuntime". It just gets stops in that function.

The image part of ARCore needs some attention...
