I,m trying to work through and test a Voice Recognition example based on the VoiceRecognition.java example at http://developer.android.com/resources/samples/ApiDemos/src/com
It appears you cannot use android:launchMode="singleInstance" when using the RecognizerIntent. I removed this from the manifest and the Voice Search runs correctly.
Thanks again Steve, for the info on USB debugging on the device. Very handy.
