Android mail client using Exchange Web Services?

Question

I'm looking for an Android e-mail client that connects to a hosted Exchange 2010 server via Exchange Web Services (EWS). I know there are several mail apps (including the stock mail client) that can work with Exchange through ActiveSync and/or WebDAV, but my server supports neither of these.

Answer 1

JWebServices for Exchange is Java API for Microsoft Exchange 2007/2010/2013 and Office 365. The API offers complete Exchange Web Services functionality including the ability to create/update/move/copy items and folders, search items and folders, send messages, send meetings requests and more. Supports JDK 1.5+ and Android 1.6+.

Answer 2

You can use Microsoft's EWS API which is Open Source for Android by doing the following steps:

1. download the source code available in the URL: http://archive.msdn.microsoft.com/ewsjavaapi EWSJavaAPI_1.1.5.zip

2. Make the changes to above API to work for JDK 1.4 in Eclipse like remove override annotations, etc.

3. Download source code of javax.* package available in below URL http://www.java2s.com/Code/Jar/j/Downloadjsr17310srcjar.htm jsr173_1.0_src.jar.zip

4. Download source code of stax API available in below URL, http://dist.codehaus.org/stax/distributions stax-src-1.2.0.zip

5. Keep all the sources under the single Java project in Eclipse

6. Open the project explorer and select the package which are starts with "javax" and rename to your company name (e.g., com). Note: Eclipse will ask for all the naming contexts will change then click OK.

7. Export all the Java sources to one single jar file.

8. Then You good to go to use the jar in Android application with out any problems.

I used the same way explained above and it worked in Android application 100% perfectly.
