Flicker on animation change when dynamic layer is changing

[atuldhanuka]

Hello Everyone,

I am adding LottieAnimationView to my layout inside ConstraintLayout. I have a one json file which is been keep in raw folder. Depending on the condition i am changing the layer index.

Like - loadData(setOf(32, 42, 44, 46, 48), binding.viewAnimation, context), loadData(setOf(0, 1, 13), binding.viewAnimation, context)

When I do this, I can see that the LottieAnimationView flickers.

`private suspend fun loadAndFilterData(
layerSet: Set,
viewAnimation: LottieAnimationView,
context: Context?
) {
withContext(Dispatchers.IO) {
try {
val inputStream: InputStream? =
context?.resources?.openRawResource(R.raw.animationjson)
val data = inputStream?.bufferedReader().use { it?.readText() }
val json = data?.let { JSONObject(it) }
// Get the layers and filter them based on the indices
val layers = json?.optJSONArray("layers") ?: JSONArray()
val newLayers = filterLayers(layers, layerSet)
// Replace the layers in the original JSON with the new filtered layers
json?.put("layers", newLayers)
// Now you would convert the modified JSON to a LottieAnimation
val animationVehicle = json.toString()
withContext(Dispatchers.Main) {
showAnimation(animationVehicle, viewAnimation)
}
} catch (e: IOException) {
DevLog.e("File Error", "Failed to read file")
} catch (e: Exception) {
DevLog.e("JSON Error", "Failed to parse or process JSON")
}
}
}

private fun showAnimation(
animationVehicle: String,
viewAnimation: LottieAnimationView
) {
viewAnimation.setAnimationFromJson(animationVehicle)
viewAnimation.speed = 1.0f
viewAnimation.playAnimation()
}`

is there a way to stop the flicker when layer is change. it should change smoothly without visible because in iOS it is happening smoothly.
