     31  * <p>
     32  * There are several reasons why we wouldn't want to use this class on an Eclair device:
     33  * <ul>
     34  * <li>It would see at most one account, namely the first Google account created on the device.
     35  * <li>It would work through a compatibility layer, which would make it inherently less efficient.
     36  * <li>Not relevant to this particular example, but it would not have access to new kinds
     37  * of data available through current APIs.
