UPDATE
Added
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
to the manifest all works ok now.
Ok so I have a app I have started to create which in the end I want to be able to take a picture, which then takes you to another screen which lets you be able to “Use” or “Retake” the picture.
When the image is took it needs to be saved into a new folder on the SD Card, (if the folder is not there then it needs to create it). I had all this working a couple of weeks ago but after i did some editing and shut down eclipse I cant seem to get it back working?
The section for this is after int imageNum = 0; i have added imagesFolder.mkdirs(); which i belive is correct to create a new folder but even this seems not to be working now.
Now the image just gets took and neither the new folder gets created or the image gets saved.

You should make sure the manifest lists the permission to write to the SD card:
