Getting toast message "Cannot play song" always when i rotate the phone while playing songs in Walkman application.
I think this is related to throw option as it shows some toast message starts with "Null is ready to use.please play music or video..."
try this
settings > apps > all > walkman > clear everything > try again
I tried it.But still same thing showing..:(
where are your songs stored? which formats?
try to use another music player like Google Music and see if you can play them, if you can not then the problem might be a corrupt audio file
