Unity addressables very slow on android device?

Hi, I use Unity 2019.2.21f1 addressables v1.6.2

I load about 20 prefabs what use about 15 textures 2048 * 2048 like this

async void Start()
{
List<Task> tasks = new List<Task>();

foreach (string prefab in eLocationPrefab.GetNames(typeof(eLocationPrefab)))
{
var op = InstantiateLocationPrefab((eLocationPrefab)Enum.Parse(typeof(eLocationPrefab), prefab));
tasks.Add(op);
}

await Task.WhenAll(tasks.ToArray());

// -- Comleted ---//
}


internal static async Task<GameObject> InstantiateLocationPrefab(eLocationPrefab prefab)
{
AsyncOperationHandle<GameObject> op = Addressables.InstantiateAsync("{0}.prefab".FormatWith(prefab.ToString()));
await op.Task;

return op.Result;
}

Settings addressables in attach

In editor all this load fast about 2 sec

On andoid device like Samsung Galaxy S7 this operation about 15 sec. If you do not use addressables and put all the prefabs on the scene, then the scene is loaded about 3 sec on android device.

Has anyone encountered such a problem and why is it so slow on android?

 

Try disabling CRCs. That was my issue in WebGL, could be the same on Android.

 

Thank you ProtoTerminator. Yes its more faster now abot 6 sec, but still still not fast. On editor its 3 sec

What more can be done?

 

I don't know what else can be done. Did you test it with regular assetbundles?

 

Yes, with regular assetbundles. I disable Use Asset Budle Cache and now 5.6 sec on Samsung Galaxy S7. On slower devices, the situation is generally deplorable.

Can someone from the unity developers comment on the problem?

 

I've been seeing similar issues, building for quest, when loading larger assets with addressables, builds crash when loading assets
