Step 3: Software Test
Download the APK file attached to this step to your phone and plug in the button you have made. Turn up your volume to 100%. The number is the sound energy of the microphone input. You should see a spike in that number and the screen should turn blue when you click the button. If this happens, you have successfully created the button!
If not, here are some trouble shooting tips:
1) Make sure your Android phone has no media audio effects on. Go to Settings -> Sound -> Media Audio Effects -> Wired Connection -> Disable Audio Effects.
2) You actually have a microphone line in to your phone
3) Media Volume is 100%
Post a comment if you cannot get it working, and I'll see if I can help.
Good luck!
