IONIC not display image from assets on device

i try

  • background-image: (‘assets/img/auth-background.jpg’) no-repeat center center fixed;
  • background-image: (’…/assets/img/auth-background.jpg’) no-repeat center center fixed;
  • background-image: (’./assets/img/auth-background.jpg’);

but ONLY device not display

my image (640x 360)
my sclass
.auth-home {
background-image: (’./assets/img/auth-background.jpg’);
background-size: 100%;
background-position-y: 50%;
}

What does that mean? Where does it show the image?

Did you remote debug the problem on the device already?

Look at the console and network tabs for errors.

Check your image path once again. Could you please share some console logs?
