DeviceCommandDialog

public class DeviceCommandDialog extends org.eclipse.swt.widgets.Dialog
Execute a command on an ADB-attached device and save the output. There are several ways to do this. One is to run a single command and show the output. Another is to have several possible commands and let the user click a button next to the one (or ones) they want. This currently uses the simple 1:1 form.
