Here’s an alternative to Dropbox and Google Drive that just appeared. Since I’m interested in moving PDFs and EPUBs around, I tried that out. Unfortunately, the Android app does not know what to do with EPUBs. You can ask the app to open the files as text, but none of my readers are available as a choice for opening the file. Same situation with PDFs, although PDFs are recognized as such and viewable inside the app.
Compare this to Google Drive. If I click on an EPUB from the Drive app, it just downloads and opens in Aldiko.
