DisplayActionSheet issues in Android

I am using a Display Action Sheet in my code. When I am trying to run on Android, the execution stops after the await sentence and the disassembly window shows up. Only after I press the continue button on top, the execution of code moves ahead.

string action = string.Empty;

            action = await DisplayActionSheet("Upload Media", "Cancel", null, "Button1", "Button2");                      

Any reason why this happens, or should I use conditions to check which platform is used and show appropriate pop ups based on the native platform support.
