问题 I am very new to java/Android development. My IDE of choice is Android Studio. Essentially I need to upload images/vidoes clips and audio clips to GCS. I am instantiating the service like this " final GcsService gcsService = >GcsServiceFactory.createGcsService(RetryParams.getDefaultInstance());" When I run the app I get the following error java.lang.NoClassDefFoundError: com.google.appengine.api.utils.SystemProperty at >com.google.appengine.tools.cloudstorage.GcsServiceFactory

问题 I currently have a web page that presents a list of records from a datastore with an edit link. I want to convert this from db. to ndb. I am a Python and GAE newbie.

问题 I am trying to launch an instance of Discourse on Google's Cloud Platform using their recently released "Launcher" (https://cloud.google.com/launcher/#/details/bitnami-launchpad:discourse?q=discourse) It is able to create a new project, but during the step "Initializing Cloud Engine" it fails -- citing "Unknown error." as the reason.

问题 In GAE, I've got a table full of "one offs" -- things like "last-used sequence number" and the like that don't really fall into other tables. It's a simple String-key with String-value pair. I've got some code to grab a named integer and increment it, like so: @PersistenceCapable(detachable="true") public class OneOff { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent private String dataKey; @Persistent private String value; public OneOff

问题 Here's my problem: class City(Model): name = StringProperty() class Author(Model): name = StringProperty() city = ReferenceProperty(City) class Post(Model): author = ReferenceProperty(Author) content = StringProperty() The code isn't important... its this django template: {% for post in posts %} <div>{{post.content}}</div> <div>by {{post.author.name}} from {{post.author.city.name}}</div> {% endfor %} Now lets say I get the first 100 posts using Post.all().fetch(limit=100) , and pass this list

问题 I am working with the Oauth2 Decorator provided by Google. Right now I am just trying to do a very simple login via Oauth2 to Google using GAE.

问题 I followed the below link to implement a "sign out" button in my android app, which uses a Google API client. However, upon connecting the google api again, the user is not presented with an account picker. It looks like the value of her/his original choice is somehow still cached perhaps. I've been trying to figure this out for a few hours. Any and all ideas very welcome.
