Mp3 player App Inventor

[luizcrf]

Hello, sorry my English.
I want to create an application with a list of songs on APP INVENTOR.
Follow the tutorial (youtube. com/watch?v=pQh16rcWSOo) below to create a mp3 button with the PLAY / STOP function.
However, I wonder how:

1º Place the PLAY / STOP function on the same button, rather than having each role on a separate button

2º Stopping a player while the other is activated
.

I want to create something like this:
brianhadaway . com/audio/oneButtonAudioPlayer . html

is it possible to do this in the APP INVENTOR?

I advise you to learn programming java android , app inventor is limited

 

[msftguy]

its possible ... if you know Java if/else you can do it

I think you should java and learn tut at androidhive about player music. Good luck
