when the chareter is visable when the camera is launch my mobile starts laging extrimaly

[SanganiKrish]

I am using lettest version of Sceneform android and still geting the same problem

[grassydragon]

Hi! Your model can be too highly detailed (have many polygons) for mobile devices.

[SanganiKrish]

I using this model in kotlin using corooting it is work smothly but when i use in java app is stuck

[grassydragon]

Do you mean that there are no lags when you use Kotlin with Sceneform?

[SanganiKrish]

yes

[SanganiKrish]

Why is this happening in Kotlin and not in Java?

[grassydragon]

Probably, that means that you block the main thread in Java while when the coroutine is suspended it frees the main thread for other tasks.

[SanganiKrish]

What should I d to free the main thread to java?

[SanganiKrish]

because in java i work on AsyncTask foe background Thread but my App is continue to stuck

[grassydragon]

You just need to use thenAccept with a callback: https://github.com/SceneView/sceneform-android/blob/993ad53f31228de3918ead4cd9509ed10347304d/samples/ar-model-viewer-java/src/main/java/com/google/ar/sceneform/samples/gltf/MainActivity.java#L94 Sceneform will load the model on a background thread.

i have used it

i have coded same as you

[grassydragon]

Try to run the sample application from the repository. I don't see any problems in your code. However, you don't need to use a Handler.
