    Hi there,

    I'm having a few problems creating a Texture2D after calling back from a C# plugin. Code below.

    Unity:
    Code (csharp):
    1.  
    2. public void GetImage()
    3. {
    4.          MyPlugin.Main.OpenImagePicker(OnGetImage);
    5. }
    6.  
    7. public void OnGetImage(string path)
    8. {
    9.         Debug.Log(path);
    10.         Texture2D texture = new Texture2D(2,2);
    11. }
    12.  
    Plugin:
    Code (csharp):
    1.  
    2. public static void OpenImagePicker(Action<string> callback)
    3. {
    4.         UnityApp.BeginInvoke(() => { callback(path); });
    5. }
    6.  
    The callback is executed fine, and the path is logged in OnGetImage, but as soon as it gets to trying to create a Texture2D, the whole app crashes. If I remove this line it works fine. If anyone has any ideas it would be massively appreciated.

    Edit: Must've been some kind of resource overload, as adding a WaitForEndOfFrame before I create the texture fixes it.

    Hi Zoooom : )
    Can you explain better your solution for this problem? I am just a novice in coding and i encountered the same problem with your native toolkit asset.
    I took the image and my app crash during the callback for a resource overload i suppose, cause that happen only with more texture on my scene.
    How can i use WaitForEndOfFrame and where? thanks : )
