Al manifiesto todo funciona bien ahora.

Ok, así que tengo una aplicación que he comenzado a crear que al final quiero ser capaz de tomar una foto, que luego te lleva a otra pantalla que le permite ser capaz de "Utilice" o "Retake" la imagen.

Cuando se toma la imagen que necesita para ser guardado en una nueva carpeta en la tarjeta SD, (si la carpeta no está allí, entonces tiene que crearlo). Tenía todo esto trabajando un par de semanas atrás, pero después de hacer algunos de edición y apagar eclipse no puedo parecer que volver a trabajar?

La sección para esto es después de int imageNum = 0; He añadido imagesFolder.mkdirs(); Que i belive es correcto para crear una nueva carpeta, pero incluso esto parece no estar funcionando ahora.

Ahora la imagen sólo se toma y ni la nueva carpeta se crea o la imagen se guarda.
