I am trying to build an android application with endpoint API, but am new to Google App Engine.

As I understand it, there's some kind of API Explorer included in the SDK that should let me test/verify my API -- the docs say: "Test the API backend in the Google APIs Explorer by navigating to http://localhost:8888/_ah/api/explorer". But I can't find any documentation of what API Explorer actually is, does, or looks like.

In my case when i click http://localhost:8888/_ah/api/explorer I get error 500

HTTP ERROR 500

Problem accessing /_ah/api/explorer. Reason:

I don't understand the error :(

this is my AsyncTask code , and Iam using Java 8

class EndpointsAsyncTask extends AsyncTask<Pair<Context, String>, Void, String> {

    private static MyApi myApiService = null;

    private Context context;

        @Override

        protected String doInBackground(Pair<Context, String>... params) {

            if(myApiService == null) {  // Only do this once

                MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(),

                        new AndroidJsonFactory(), null)

                        // options for running against local devappserver

                        // - 10.0.2.2 is localhost's IP address in Android emulator

                        // - turn off compression when running against local devappserver

                        .setRootUrl("http://10.0.2.2:8888/_ah/api/")

                        .setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {

                            @Override

                            public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest) throws IOException {

                                abstractGoogleClientRequest.setDisableGZipContent(true);

                            }

                        });

                // end options for devappserver



                myApiService = builder.build();

            }



            context = params[0].first;

            String name = params[0].second;



            try {

                 return myApiService.sayHi(name).execute().getData();

            } catch (IOException e) {

                return e.getMessage();

            }

        }



        @Override

        protected void onPostExecute(String result) {

            Toast.makeText(context, result, Toast.LENGTH_LONG).show();

        }

    }

and this is my Endpoint code

@Api(

        name = "myApi",

        version = "v1",

        namespace = @ApiNamespace(

                ownerDomain = "backend.builditbigger.gradle.udacity.com",

                ownerName = "backend.builditbigger.gradle.udacity.com",

                packagePath=""

        )

)

public class MyEndpoint {



    /** A simple endpoint method that takes a name and says Hi back */

    @ApiMethod(name = "sayHi")

    public MyBean sayHi(@Named("name") String name) {

        MyBean response = new MyBean();

        response.setData("Hi, " + name);



        return response;

    }

}
