Nithin is right, you need to add the following permission to your
AndroidManifest.xml, if it's not there already:
<uses-permission id="android.permission.CALL_PHONE"/>
You'll find that the KEYCODE_CALL button is being ignored, because by
default special buttons like the back/call/home ones are handled
internally. You need to override this behaviour by adding the
following line into the onCreate() of your activity:
setDefaultKeyMode(Activity.DEFAULT_KEYS_DIALER);
The rest looks OK to me. If you still have problems, try stepping
through the code in the debugger to determine which line is not
executing correctly...
