lo hice, y después de un tiempo la aplicación se ejecuta, el error es: 12-16 18: 09: 47.406: ERROR/Base de datos (21184): android.database.sqlite.DatabaseObjectNotClosedException: La aplicación no se cerró el cursor o el objeto de la base de datos que se abrió aquí Creo que es el cursor el que debe cerrarse. ¿Cómo puedo cerrarlo? – rogcg
@psyhclo: ¿Has visto mi edición? Tiene dos instancias de OpenHelper, cada una de las cuales se usa para obtener una conexión de base de datos, por lo que ambas deben estar cerradas. (Es posible que desee combinar esos dos OpenHelpers; esa es su llamada). –
El método close() debe estar dentro de qué clase, OpenHelper o CallDataHelper. El campo openHelper está en CallDataHelper, pero cuando trato de declarar el método close, dice esto: openHelper no se puede resolver en una variable. Y ofrece crear el campo. Obs: Estoy declarando el método close() en CallDataHelper. Y si trato de hacer esto: public void close() { \t \t // NOTA: openHelper ahora debe ser miembro de CallDataHelper; \t // actualmente lo tiene como local en su constructor \t if (this.db! = Null) { \t \t this.db.close(); \t} – rogcg
