1<p>AdbTest is a sample program that implements a subset of the <code>adb</code> USB protocol. 2Currently it only implements the <code>adb logcat</code> command and displays the log 3output in a text view and only allows connecting to one device at a time. 4However, the support classes are structured in a way that would allow 5connecting to multiple devices and running multiple <code>adb</code> commands simultaneously.</p> 6 7<p>This program serves as an example of the following USB host features:</p> 8 9<ul> 10<li>Matching devices based on interface class, subclass and protocol (see <code>device_filter.xml</code>)</li> 11 12<li>Asynchronous IO on bulk endpoints</li> 13</ul>
