This sample for Android is a repository of simple method examples that access email, calendar events, contacts, and files in Office 365. These "snippet" methods are self contained so you can paste them into your own code or use as reference for learning.

This sample includes the following operations:
Calendar
- Get existing calendar events by date range.
- Create an event.

To run the snippets project your device needs to meet the following requirements:
- Android API level 16 or newer.
To use the Office 365 Code Snippets for Android you need the following:
- The latest version of Android Studio.
- The Gradle build automation system version 2.2.1 or later.
- An Office 365 account. You can sign up for an Office 365 Developer subscription that includes the resources that you need to start building Office 365 apps.
- Java Development Kit (JDK) 7.
- A registered Azure application with a client id and redirect uri value. The application must have the following permissions:
- Windows Azure Active Directory
- Enable sign-on and read user's profiles.
- Access your organization's directory.
- Office 365 SharePoint Online
- Read and write user files.
- Office 365 Exchange Online
- Read and write user mail.
- Send mail as a user.
- Read and write user calendars.
- Read and write user contacts.
- Windows Azure Active Directory
Each client application that you register with Azure can have its own unique set of permission requirements, application title, and redirect URL. Unless you have an existing application registration that uses the same combination of permissions, title, and URL, you should create a new registration for each app.
- Register a native client application in Azure Active Directory and assign the required permissions to the sample application in Azure.
Note: Be sure to select the native client application on step 5 of the Azure Management Portal azure application procedure.
Open the project by importing the settings.gradle file.
-
Install Android Studio and add the Android SDK packages according to the instructions on developer.android.com.
-
Download or clone the Office 365 Code Snippets for Android.
-
Start Android Studio.
-
From the Welcome to Android Studio dialog box, choose Import project (Eclipse ADT, Gradle, etc).
-
Respond to the dialog ("Gradle Sync: Gradle settings for this project are not configured yet. Would you like the project to use the Gradle wrapper? ") by clicking the OK button to use the Gradle wrapper
-
Select the settings.gradle file in the O365-Android-Snippets folder and click OK.
-
Open
Constants.java. -
Find the
CLIENT_IDconstant and set its String value equal to the client id you registered in step 1. -
Find the
REDIRECT_URIconstant and set its String value equal to the redirect URI you registered in step 1.
Note: The starter project declares the required dependencies using Gradle. The dependencies are:
Once you've built the snippets project you can run it on an emulator or device.
- Run the project.
Note: The sample is designed to run in landscape mode. If you want to run the sample in portrait mode, change the orientation of the emulator by pressing the ctrl-f12 key combination on a Windows computer and control-f12 on a OSX computer.
- Click the "Connect" item on the action bar overflow menu and enter your credentials.
- Click a task in the main activity list to run a task.
- View the results of the task in the detail pane to the right of the list.
- Optionally, clear the results of the task by clicking the "Clear Results" action bar item.
- Run all tasks in the list sequentially by clicking the "Run All" action bar item.
The starter project uses these classes to manage interactions with Office 365:
These classes have snippet methods that wrap calls to the SharePointClient and OutlookClient objects in the Office 365 SDK for Android. Look at the classes in the com.microsoft.office365.snippetapp.O365Stories package to see how the snippets are called.
The Office 365 SDK for Android uses the Azure Active Directory Library (ADAL) for Android for connecting your app to Office 365. The ADAL provides protocol support for OAuth2, Web API integration with user level consent, and two-factor authentication.
The AuthenticationController object manages getting a token from ADAL and returning it to your application.
The CalendarSnippets object wraps the API operations that create, update and delete calendar events in an Office 365 Exchange calendar.
The getO365Events method gets a list of events from the Office 365 calendar and loads pages of events into a local list. Changes, deletions, and additions to this list are posted asynchronously to the Office 365 calendar by the updateCalendarEvent, deleteCalendarEvent, and createCalendarEvent methods.
The FileFolderSnippets object wraps the API operations that create, update, and delete files stored on OneDrive for Business.
The getFilesAndFoldersFromService method gets a list of all of the files and folders that are stored on OneDrive for Business and loads the list into a local array. Changes, deletions, and additions to the local list of files are posted asynchronously to OneDrive for Business by the postUpdatedFileToServer, deleteFileFromServer, and postNewFileToServer methods.
The getFilesAndFolders method returns a list of Item objects containing the selected files contents.
The EmailSnippets object wraps the API operations that create, update and delete mail items in an Office 365 Exchange mailbox.
The getMailMessages method gets a list of mail items from the Office 365 mailbox and loads pages of items into a local list. Deletions to this list, and mail sent from the mailbox are posted asynchronously to the Office 365 calendar by the deleteMail, sendMail, forwardMail, and replyToEmailMessage methods.
The ContactsSnippets object wraps the API operations that create, update and delete contacts in Office 365 Exchange.
The getContacts method gets a list of contacts from Office 365 and loads pages of contacts into a local list. Changes, deletions, and additions to this list are posted asynchronously to Office 365 by the updateContact, deleteContact, and createContact methods.
The UsersAndGroupsSnippets object wraps the API operations for working with users, groups, and other Azure Active Directory data. Office 365 users and groups are stored in Azure Active Directory.
The getUsers method gets a list of all users from the Office 365 tenant. Similarly getGroups gets all the groups from the Office 365 tenant. getTenantDetails will retrieve information about the Office 365 tenant itself.
We'd love to get your feedback on the O365 Android Snippets project. You can send your questions and suggestions to us in the Issues section of this repository.
Questions about Office 365 development in general should be posted to Stack Overflow. Make sure that your questions or comments are tagged with [Office365] and [API].
