Android Guardar imagen en la tarjeta SD

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

al manifiesto todo funciona bien ahora.

Ok, así que tengo una aplicación que he comenzado a crear, que al final quiero poder tomar una foto, que luego te lleva a otra pantalla que te permite "Usar" o "Volver a tomar" el imagen.

Cuando se toma la imagen, debe guardarse en una nueva carpeta en la tarjeta SD (si la carpeta no está allí, entonces necesita crearla). Estuve todo esto funcionando hace un par de semanas, pero después de hacer algunas ediciones y cerrar el eclipse, parece que no puedo volver a funcionar.

La sección para esto es después de int imageNum = 0; he agregado imagesFolder.mkdirs(); que creo que es correcto crear una nueva carpeta pero incluso esto parece no estar funcionando ahora.

Ahora se acaba de capturar la imagen y no se crea la nueva carpeta o se guarda la imagen.

Debe asegurarse de que las listas de manifiesto el permiso para escribir en la tarjeta SD:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
