Estoy creando una aplicación para Android que simplemente tomará una imagen de sdcard (galería de teléfonos) y la almacenará en el disco de Google. Hice mucho esfuerzo en esto, tomé ayuda del código provisto por los desarrolladores de Google enconducir inicio rápido. Hice un control de botón en mi archivo main.xml, cuando hago clic en este botón, aparece dentro de la galería del teléfono y cuando selecciono una imagen, no pasa nada.

Este es Log Cat de mi eclipse IDE
