Use the OneDrive app in your Android device to work with your personal OneDrive account as well as your OneDrive for Business accounts. If your device is running Android 4.0 or a newer version, you can use the one app to work with both.
Add a OneDrive for Business account
In the OneDrive app, tap the Menu icon, and then tap Add OneDrive for Business.
Sign in using the username and password you use for OneDrive for Business.
Note: If you want to sign in with a OneDrive for Business account, your organization needs to have a qualifying SharePoint Online or Office 365 business subscription plan. You can't sign in with an account from an on-premises directory.
Switch between accounts
To switch between a personal OneDrive account and a OneDrive for Business account, or between multiple OneDrive for Business accounts, tap the Menu icon, and then tap the account you want to use.
Tip: You can add only one personal account to the OneDrive app. To open a different personal account, open Settings, tap your account name, tap Sign out, and then sign in with the account you want to use.
