1*90c8c64dSAndroid Build Coastguard Worker<p>AdbTest is a sample program that implements a subset of the <code>adb</code> USB protocol. 2*90c8c64dSAndroid Build Coastguard WorkerCurrently it only implements the <code>adb logcat</code> command and displays the log 3*90c8c64dSAndroid Build Coastguard Workeroutput in a text view and only allows connecting to one device at a time. 4*90c8c64dSAndroid Build Coastguard WorkerHowever, the support classes are structured in a way that would allow 5*90c8c64dSAndroid Build Coastguard Workerconnecting to multiple devices and running multiple <code>adb</code> commands simultaneously.</p> 6*90c8c64dSAndroid Build Coastguard Worker 7*90c8c64dSAndroid Build Coastguard Worker<p>This program serves as an example of the following USB host features:</p> 8*90c8c64dSAndroid Build Coastguard Worker 9*90c8c64dSAndroid Build Coastguard Worker<ul> 10*90c8c64dSAndroid Build Coastguard Worker<li>Matching devices based on interface class, subclass and protocol (see <code>device_filter.xml</code>)</li> 11*90c8c64dSAndroid Build Coastguard Worker 12*90c8c64dSAndroid Build Coastguard Worker<li>Asynchronous IO on bulk endpoints</li> 13*90c8c64dSAndroid Build Coastguard Worker</ul>
