Dúvida no Ex. 9 da Aula 5 - Persistência com SQLite

Ola Flávio, bom dia !

Você poderia colocar o erro que é gerado aqui para gente ver ?

Abraços

Matheus

Onde posso pegar o Log de erros? pois no emulador só aparece "o aplicativo parou"

Quando o emulador apresenta essa informação um exception é lançada e pode ser vista no logCat.
