sorry if there's already a tutorial .My English is not very good,hope you can understand what i'm saying.
I have a background music in my game ,and a SFX when you shot the monster.The preview on computer is no problem,but I export it to cocoonJS,and install the APK file on my andriod mobile phone,there's only one sound playing.almost is the shotting SFX,the background music played just about 0.5 second then stopped.
how can i fix this?
