Boa tarde,

Bom , eu sou novo no fórum espero ter criado o topico no local correto:

A duvida é a seguinte, preciso fazer um player de musica, ja consegui fazer rodar …
mas tenho algumas duvidas

1º - Como crio uma playlist? usando o metodo setOnEndOfMedia , do mediaPlayer
2º como pego as informações (nome da musica, cantos, autos, etc…) do arquivo que esta rodando.
