Android, filament gltf viewer freezes emulator

kelvinwatson opened this issue 2 years ago · comments

Describe the bug
Emulator freezes periodically when running a simple gltf viewer app. Pasted all application code as it is a very small app.

build.gradle

    implementation 'com.google.android.filament:filament-android:1.19.0'
    implementation 'com.google.android.filament:filament-utils-android:1.19.0'
    implementation 'com.google.android.filament:gltfio-android:1.19.0'

class MainActivity : AppCompatActivity() {
    companion object {
        init {
            Utils.init()
        }
    }

    private val frameCallback = object : Choreographer.FrameCallback {
        override fun doFrame(currentTime: Long) {
            choreographer.postFrameCallback(this)
            modelViewer.render(currentTime)
        }
    }

    private lateinit var surfaceView: SurfaceView
    private lateinit var choreographer: Choreographer
    private lateinit var modelViewer: ModelViewer

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        surfaceView = SurfaceView(this).apply {
            setContentView(this)
        }
        choreographer = Choreographer.getInstance()
        modelViewer = ModelViewer(surfaceView)
        surfaceView.setOnTouchListener(modelViewer)

        loadGlb("DamagedHelmet")

        modelViewer.scene.skybox = Skybox.Builder().build(modelViewer.engine)

        // make background white
        val white = Color.WHITE
        val alpha = Color.alpha(white).toFloat()
        val red = Color.red(white).toFloat()
        val green = Color.green(white).toFloat()
        val blue = Color.blue(white).toFloat()

        modelViewer.scene.skybox =
            Skybox.Builder().color(red, green, blue, alpha).build(modelViewer.engine)
    }

    override fun onResume() {
        super.onResume()
        choreographer.postFrameCallback(frameCallback)
    }

    override fun onPause() {
        super.onPause()
        choreographer.removeFrameCallback(frameCallback)
    }

    override fun onDestroy() {
        super.onDestroy()
        choreographer.removeFrameCallback(frameCallback)
    }

    private fun loadGlb(name: String) {
        val buffer = readAsset("models/${name}.glb")
        modelViewer.loadModelGlb(buffer)
        modelViewer.transformToUnitCube()
    }

    private fun loadEnvironment(ibl: String) {
        // Create the indirect light source and add it to the scene.
        val buffer = readAsset("envs/$ibl/${ibl}_ibl.ktx")
        KTXLoader.createIndirectLight(modelViewer.engine, buffer).apply {
            intensity = 50_000f
            modelViewer.scene.indirectLight = this
        }
    }

    private fun readAsset(assetName: String): ByteBuffer {
        val input = assets.open(assetName)
        val bytes = ByteArray(input.available())
        input.read(bytes)
        return ByteBuffer.wrap(bytes)
    }
}

To Reproduce
Steps to reproduce the behavior:

Run the app with the code above on an emulator
Observe that the emulator freezes. Observe that this does not occur on a physical device.

Expected behavior
Emulator should not freeze when running a simple Filament app.

Is the emulator frozen or the app? If the former, that sounds like an emulator bug. I've never seen this issue myself even though I regularly work in the emulator.

@romainguy It's definitely the emulator. The 3 soft nav buttons become unresponsive to taps. The controls on the panel beside of the emulator also become unresponsive.

This should be reported against the emulator at b.android.com then, sorry :/
