According to the docs:

A namespace becomes a bundle as soon as you add a bundle class to it. The bundle class name must follow these simple rules:

...
Prefix the name with the concatenation of the vendor (and optionally the category namespaces);

The Doctrine Bundle relies on this convention to find your metadata. So the namespace of your bundle should be something like YourName\AppBundle.
