I am trying to send a request to the Google GeoCode API using Retrofit. The service interface looks like this:
public interface FooService {
@GET("/maps/api/geocode/json?address={zipcode}&sensor=false")
void getPositionByZip(@Path("zipcode") int zipcode, Callback<String> cb);
}
When I call the service:
OkHttpClient okHttpClient = new OkHttpClient();
RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint(Constants.GOOGLE_GEOCODE_URL).setClient(new OkClient(okHttpClient)).build();
FooService service = restAdapter.create(FooService.class);
service.getPositionByZip(zipCode, new Callback<String>() {
@Override public void success(String jsonResponse, Response response) {
...
}
@Override public void failure(RetrofitError retrofitError) {
}
});
I receive the following stacktrace:
06-07 13:18:55.337: E/AndroidRuntime(3756): FATAL EXCEPTION: Retrofit-Idle

I took a look at the StackOverflow question: Retrofit: multiple query parameters in @GET command? but it did not seem applicable.
I took the code pretty much verbatim from here: http://square.github.io/retrofit/ so I am a bit of a loss to understand the issue.
Thoughts?
AFAIK, {...}
can only be used as a path, not inside a query-param. Try this instead:
public interface FooService {
@GET("/maps/api/geocode/json?sensor=false")
void getPositionByZip(@Query("address") String address, Callback<String> cb);
}
If you have an unknown amount of parameters to pass, you can use do something like this:
public interface FooService {
@GET("/maps/api/geocode/json")
@FormUrlEncoded
void getPositionByZip(@FieldMap Map<String, String> params, Callback<String> cb);
}
