If you are using the default Dropbox app for Android, you will find that it can only link to a single Dropbox account. If you need to access another account, you will need to unlink the current account and login with the next account. This shouldn’t be a problem if you only need to access the alternate account once in a blue moon. However if you constantly need to access multiple Dropbox accounts on Android, you will need a better solution than the default Dropbox app for Android.
