oframe is null?

Question

I included a scene with easyAR 3.0 in an assetbundle of unity but when opening it in android it presents this error ([EasyAR] oframe is null), and this (Uknown error), how can I fix this?

Answer 1

"[EasyAR] oframe is null" is not an error. It's possible in normal runs.

And for "Uknown error", where do you get this error? Do you have any call stack information?

I am trying to load the Image Target from the persistent data path and get this:

[EasyAR]:/storage/emulated /0/Android/data/com.wijari.prototype/files/namecard.jpg
[EasyAR] use ezar camera device
[EasyAR] RequestPermissions status Granted msg

Unknown Error
<LoadImageTarget>d_18:MoveNext()
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

[EasyAR] oframe is null
[EasyAR] oframe is null
[EasyAR] oframe is null ...

Also try reading the ImageTarget from Streaming Assets but the application closes by itself

In unity editor works correctly with Streaming Assets and Persistent Data Path.

maybe you miss the "file://" header, www path need the header, so your path should be "file://xxxx/xxxx/xxx/xxx.jpg"

thanks, this works for me, this is the final code:

           path = Utility.AddFileHeader(Application.persistentDataPath + "/"  + path);
           UriBuilder uriBuilder = new UriBuilder(path);
           uriBuilder.Scheme = "file";  
           path = uriBuilder.ToString();
