ScreenCapture example fails if directory doesn't exist

[Google Code Exporter]

What steps will reproduce the problem?
1. Clone the andengineexamples project
2. Run the ScreenCapture Example for the first time (clean install)
3. Capture will fail

What is the expected output? What do you see instead?
Capture saved to sd card. 
Capture is not saved, it fails because the directory doesn't exist. Once the 
directory is created it works as expected.

ERROR/AndEngine(732): java.io.FileNotFoundException:

I'm using the ScreenCapture class, and when my app try to capture image and 
save in SDCard using FileUtils.getAbsolutePathOnExternalStorage(), I get the 
same error.
