Android takePicture ha fallado

He estado intentando hacer una aplicación de la cámara para el androide pero cuando intento tomar la imagen, él insectos y tengo que forzar cerca. El LogCat es:

He intentado tanto camera.takePicture(null, null, photoCallback); Y camera.takePicture(ShutterCallback, rawCallback, photoCallback); , Como se puede ver, y también leí en algún lugar que System.gc(); Podría funcionar, pero no lo hizo. Además, leí que un problema común era olvidar reiniciar la vista previa después de tomar la foto, pero estoy llamando a camera.startPreview(); Después de que, por lo que realmente no sé lo que está pasando!

Estoy ejecutando Android 2.3.3 (Motorola Razr). (Parece que muchas personas tienen problemas con la cámara en Android 2.3.3 …).

Estaría muy agradecido si alguien pudiera ayudar!

HE CARGADO TODO EL PROYECTO A http://www.4shared.com/rar/meSWrQPm/CameraTest.html

He descargado una aplicación que mostró este registro … Tal vez hay algo aquí que podría ayudar: parece que el problema se produjo al crear el directorio de archivos. ¿Como puedo resolver esto?
