You can use the Metadata API. For example:

Query query = new Query(Entities.KIND_METADATA_KIND);
DatastoreService datastoreService = DatastoreServiceFactory.getDatastoreService();

Iterable<Entity> entityIterable = datastoreService.prepare(query).asIterable();

for(Entity entity : entityIterable) {
    System.out.println("Entity kind: " + entity.getKey().getName());
}
