755 PointsCrystal Ball sound not working when loaded in phone
The app was perfectly working before I removed the button. Then when I put the shake detector and loaded it in my phone, the sound was gone. Everything is working fine. I have xperia z1 if that matters.

Treehouse TeacherDo you get any kind of errors in logcat or the console? Is it just the sound that isn't working? It could be a device-specific issue.

755 PointsNo. I checked it. There's nothing in there. I'll try to use different device and see if that works. If it does, what specifically could have caused that?

Treehouse TeacherMost device manufactures modify the base Android operating system, and sometimes introduce bugs. If it works on other devices then it is most likely related to the hardware and its version of the operating system. You'd have to track down a solution from there, which can be a pain. This is the biggest gripe of Android developers. :-/
