Having trouble creating transparent material on Android?

I’m having trouble creating transparent objects on Android. I’ve created a material that appears transparent on my computer but becomes visible when I build and run it on my Android device.

Here’s how the scene looks like on my computer:

And here it is on my Android:

And here’s the inspector window of the matieral:

What am I doing wrong??

use alpha map
or do your image background in white color, bcoz white color is use as transparent map.

best of luck
