How to disable GZipContent in Cloud Endpoints builder in Android

Question

I want to disable GZipContent for a Google Cloud Endpoints class so that a POST can work on the local development server.

The latest GPE release generates this endpoint builder:

public static final class Builder extends AbstractGoogleJsonClient.Builder {
    public Builder(HttpTransport transport, JsonFactory jsonFactory,
        HttpRequestInitializer httpRequestInitializer) {
      super(
          transport,
          jsonFactory,
          ...);
    }

and Google documentation recommends using it like this:

Myendpoint.Builder endpointBuilder = new Myendpoint.Builder(
                    AndroidHttp.newCompatibleTransport(),
                    new GsonFactory(),
                    credential);

Does anyone know how to disable GZipContent for the endpoint?

Thanks.

You can use:

builder.setGoogleClientRequestInitializer(new TictactoeRequestInitializer() {
     protected void initializeTictactoeRequest(TictactoeRequest<?> request) {
         request.setDisableGZipContent(true);
     }
   });

Replace TictactoeRequest with the appropriate class for your application.

Thanks Dan! That looks just right (I noticed the control in the xxxxxRequestInitializer but wasn't sure how to use it). I'll test it later when I'm done with my day-job and accept the answer then. – aez Mar 13 '13 at 18:37

I'm not 100% why Dan's answer didn't work for me, but this GitHub project's code solved it for me.

/*
 * TODO: Need to change this to 'true' if you're running your backend locally using
 * the DevAppServer. See
 * http://developers.google.com/eclipse/docs/cloud_endpoints for more
 * information.
 */
protected static final boolean LOCAL_ANDROID_RUN = false;

/*
 * The root URL of where your DevAppServer is running (if you're running the
 * DevAppServer locally).
 */
protected static final String LOCAL_APP_ENGINE_SERVER_URL = "http://localhost:8080/";

/*

 * accessed via the Android emulator (if you're running the DevAppServer
 * locally). In this case, you're running behind Android's virtual router.

 */
protected static final String LOCAL_APP_ENGINE_SERVER_URL_FOR_ANDROID = "http://10.0.2.2:8080";

/**
 * Updates the Google client builder to connect the appropriate server based
 * on whether LOCAL_ANDROID_RUN is true or false.
 *
 * @param builder Google client builder
 * @return same Google client builder
 */
public static <B extends AbstractGoogleClient.Builder> B updateBuilder(
        B builder) {
    if (LOCAL_ANDROID_RUN) {
        builder.setRootUrl(LOCAL_APP_ENGINE_SERVER_URL_FOR_ANDROID
                + "/_ah/api/");
    }

    // only enable GZip when connecting to remote server
    final boolean enableGZip = builder.getRootUrl().startsWith("https:");

    builder.setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
        public void initialize(AbstractGoogleClientRequest<?> request)
                throws IOException {
            if (!enableGZip) {
                request.setDisableGZipContent(true);
            }
        }
    });

    return builder;
}

For those that are Googling for the error I saw, it was java.io.EOFException, but only in the development server. Here's how I was able to fix this, using the example stated in the OP's question:

Myendpoint myendpointClient = new Myendpoint.Builder(
                AndroidHttp.newCompatibleTransport(),
                new GsonFactory(),
                credential).build();
EndpointService svcCall = myendpointClient.endpointService("firstArg");
// Note, I didn't call "execute()", as normal!
svcCall.setDisableGZipContent(true);
// This is also a handy place to set http headers, etc
svcCall.getRequestHeaders().set("x-oddballhdr","OddballValue");
// It's now time to call execute()
svcCall.execute();

That may be a bit simpler than the other helpful answers.
