[SOLVED] Crashing App: Download asset bundle for use in AR on Android

I hope someone can help. Sorry if this is obvious but I have been trying to download my asset for days to use in Augmented Reality, with no luck.

I created a bundle with:

Code (CSharp):

1. [MenuItem("Assets/Build AssetBundles")]
2.     static void BuildAllAssetBundles()
3.     {
4.         BuildPipeline.BuildAssetBundles(@"F:\MyPath", BuildAssetBundleOptions.None, BuildTarget.Android);
5.     }

I uploaded all the generated files onto my web server using Binary upload.

Then, in my scene, I download the bundle using:

Code (CSharp):

1.  
2. public string assetName;
3. private GameObject asset;
4.  
5. IEnumerator Start()
6.     {
7.         using (UnityWebRequest uwr = UnityWebRequestAssetBundle.GetAssetBundle("https://MyPath/argirl"))
8.  
9.         {
10.             yield return uwr.SendWebRequest();
11.  
12.             if (uwr.isNetworkError || uwr.isHttpError)
13.             {
14.                 Debug.Log(uwr.error);
15.             }
16.             else
17.             {
18.                 // Get downloaded asset bundle
19.                 AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(uwr);
20.                 asset = bundle.LoadAsset<GameObject>(assetName);
21.                 //Instantiate(asset);
22.             }
23.         }
24.        
25.         /*string url = "https://MyPath/argirl";
26.         UnityEngine.Networking.UnityWebRequest request
27.             = UnityEngine.Networking.UnityWebRequestAssetBundle.GetAssetBundle(url, 0);
28.         yield return request.SendWebRequest();
29.         AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(request);
30.         asset = bundle.LoadAsset<GameObject>(assetName);
31.         //Instantiate(asset);*/
32.     }

The commented out code above is another way I tried. Both work fine in Unity during run time using Instantiate(asset), but when I build it to my Android phone, it loads the asset bundle and then crashes the app when I try to place the "asset" GameObject in augmented reality later on.

I've read a lot on forums about different things to use but I'm new to asset bundles and don't know how to fix this. Also, I'm working with Unity 2019.3.0f6. Any help is appreciated!!!

 

No, it isn't null. It loads the asset fine when I test it in unity, like I said.

 

Isn't this building a bundle for Android??
BuildPipeline.BuildAssetBundles(@"F:\MyPath", BuildAssetBundleOptions.None, BuildTarget.Android);

 

OK... turns out that it was something SUPER obvious. lol I needed to add .prefix to my asset nameName. Glad to know my code above was correct though!

 

Please tell me how you solved this problem?

 

Umm... like I said, I added the .prefix to my asset name when calling it.
