Pessoal.
-- Estou tendo o erro
java.lang.NullPointerException: Attempt to invoke virtual method on a null object reference
Isso porque minha context está null, mas se a crio desde a MainActivity recebo o erro que preciso ter um construtor com 0 argumentos.
"MainActivity has no zero argument constructor"
"MainActivity has no zero argument constructor"
Agradeço desde já!
