As I promised, I am stuck and have come back again. I have copied one of my apps onto my hudl and it runs well, just as good as on my PC.
However, it has no sound. On this app there are only 2 sounds, an explosion and a failed sound. I looked elsewhere in this forum and came across the advice, "my notes about wave files for android:
sound must be wave (PCM) 16 bits , 2 channels (stereo) sampling rate 44.1 KHz". I tried using Audacity to set my 2 wav files to 16 bits, stereo and 44.1 KHz and I think that I managed but still no sounds
Any ideas?
