Example Code

I have attached some example code that should allow you to test various configurations. ?Let me know if you find it useful (or not).D
Download here ->?MediaStoreTest

From the code (the essential parts)

final Bundle extras = data.getExtras();
if (extras != null) {
File tempFile = getTempFile();
// new logic to get the photo from a URI
if (data.getAction() != null) {
processPhotoUpdate(tempFile);
}
}
}
break;
}
}
