red question mark loading image as texture with Firebase storage
I'm trying to load image from firebase storage, but all that I get is a red question mark in unity or even when I build the application in android this is my script that I use ** I had a start function (start) to get all the data from firebase storage**
private void Start()
{
const long maxAllowedSize = 1 * 1024 * 1024;
storage_ref.Child(InputManager.ButtonName).Child("GoodAnswer.png").GetBytesAsync(maxAllowedSize).
ContinueWith((Task<byte[]> task) =>
{
if (task.IsFaulted || task.IsCanceled)
{
Debug.Log(task.Exception.ToString());
}
else
{
fileContents1 = task.Result;
Debug.Log("Finished downloading!");
}
});
storage_ref.Child(InputManager.ButtonName).Child("BadAnswer1.png").GetBytesAsync(maxAllowedSize).
ContinueWith((Task<byte[]> task) =>
{
if (task.IsFaulted || task.IsCanceled)
{
Debug.Log(task.Exception.ToString());
}
else
{
fileContents2 = task.Result;
Debug.Log("Finished downloading!");
}
});
storage_ref.Child(InputManager.ButtonName).Child("BadAnswer2.png").GetBytesAsync(maxAllowedSize).
ContinueWith((Task<byte[]> task) =>
{
if (task.IsFaulted || task.IsCanceled)
{
Debug.Log(task.Exception.ToString());
}
else
{
fileContents3 = task.Result;
Debug.Log("Finished downloading!");
}
});
}
And this is the function I call when I click on load button
public void Load()
{
int height = 1024;
int width = 1024;
target1 = new Texture2D(height, width, TextureFormat.RGB24, false);
target2 = new Texture2D(height, width, TextureFormat.RGB24, false);
target3 = new Texture2D(height, width, TextureFormat.RGB24, false);
//target.LoadRawTextureData(fileContents);
//target.Apply();
//target.EncodeToJPG();
//imgLoad.texture = target;
target1.LoadImage(fileContents1);
target2.LoadImage(fileContents2);
target3.LoadImage(fileContents3);
imgLoad1.texture = target1;
imgLoad2.texture = target2;
imgLoad3.texture = target3;
Debug.Log("Finished downloading!");
}
this is what I get when I run my application on the editor or my android phone
This is all my script to more understand my problem

anyone have any idea how to fix it, please

Image img = System.Drawing.Image.FromFile(path);
Texture2D tex = new Texture2D(image.Width, image.Height, TextureFormat.RGB24, false, false);
MemoryStream ms = new MemoryStream();
image.Save(ms, ImageFormat.Png);
ms.Seek(0, SeekOrigin.Begin);
tex.LoadImage(ms.ToArray());
tex.Apply();
ms.Close();
