ADE doesn't support fixed layout yet. I'm not familiar with Aldiko. It should work on ibooks. Try Chrome's Readium.
There has been an announcement (mentioned in Anne-Marie's webinar on Fixed Layout EPUB) that ADE will be updated in the fall for proper display of EPUB3, including Fixed Layout.
Great news Steve.
Adobe Digital Editions has come up with a new update ADE 4. You can view your Fixed Layout EPUB here. Please note that ADE 4 on Mac works fine with FXL EPUB exported from InDesign CC 2014, you might see some issue on Windows though. We are aware of the issues and the team is working on fixing these issues with ADE on Windows.
Readium is also a good reader which displays FXL EPUB fine.
Except it's not true. ADE 4.5.2 on Windows won't display fonts correctly. Try Readium instead.
