In your 'public void onPictureTaken(byte[] data, Camera camera)'
method
You have to create a BMP out of the 'data'. The 'data' is not JPEG. It
is RGB data (if i'm not mistaken).
Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
Then you compress the bitmap into jpeg.
bmp.compress(...) to create a PNG or JPEG file.
A side note: If you want to avoid the MediaScanner to have to run
before your gallery can actually see the proper picture, supply the
DATA column in your insert statement (add it to the ContentValues).
The value of the DATA column is a string, it is the fully-qualified
path-name to your JPEG or PNG file.
