Obs. O fato de todas as activity estarem com Action Main e category Launcher é q eu estava testando uma a uma.

        startActivity(it);  
  
    }  
    Canais linhaSelecionada = (Canais) o;   
    String c = linhaSelecionada.getCodCanal();

Por que essas linhas estão fora do método?

Repare que é o linhaSelecionada que é null.

Bom dia, Marky.Vasconcelos

Perfeito velho exatamente isso…

Estava fazendo alguns teste e acabei deixando fora do metodo…eu não estava conseguindo chegar com o debug até ae, por isso não percebi…

Mto Obrigado
