A lot of people have been asking us about getting their Access Hosting Application and SharePoint 2010 site working on their Android Phone or Android Tablet. Let me start off by saying that we have not tested every Android device out there (there are a lot), but we have been successful getting our own simple hosted web contacts database working on a variety of Android phones.
The key problem that people run into when using Android is that the default browser is not supported by Microsoft SharePoint and blocks the authentication prompt. The fix is very simple. Download the free Mozilla FireFox browser from the Android Marketplace.
Mozilla FireFox is a fully supported browser by Microsoft for SharePoint 2010 and while every SharePoint feature may not work on the phone, you certainly can view all your Access web forms, reports, and queries.
