Hi, Many people on here have a hard time getting their .acsm file to work on their Android device using the Adobe Digital Editions app, and these steps will help you open the .acsm correctly.
This worked for me on March 6th 2019.
I don't have the option to 'create shortcut' in the 3 dots menu
I had to hold down to select the file, then press Menu in the bottom right of the screen. In there, the bottom option was to create a shortcut on the home screen. Apart from this (step 8), tysonpdc's worked perfectly for me today on Android 6.0.
I appeciate the guide!
