The platform specific documentation for Android mentions you need to put your banks in a Mobile subdirectory and make some modifications to the AndroidGame.ini file.
Here are the steps in more detail:

  1. Open {gamename}\Config\Android\ AndroidGame.ini (Create any folders or files that don’t already exists)
  2. In the file, paste the following text:
[/Script/UnrealEd.ProjectPackagingSettings]
-DirectoriesToAlwaysStageAsNonUFS=(Path="FMOD/Desktop")
+DirectoriesToAlwaysStageAsNonUFS=(Path="FMOD/Mobile")
  1. In {gamename}\Content\FMOD, create a folder called “Mobile”
  2. Copy and paste the banks in
    {gamename}\Content\FMOD\Desktop
    to
    {gamename}\Content\FMOD\Mobile

You should now be able to build to Android
