java - Error: cannot find symbol class Builder (using Retrofit) -
been following retrofit tutorial, stuck on issue:
error:(12, 46) error: cannot find symbol class builder
here's file, restadapter.java:
package com.myapp.jobapp; import retrofit.restadapter.builder; import retrofit.restadapter; public class restadapter { public static final string base_url = "http://api.myservice.com"; restadapter restadapter = new restadapter.builder() .setendpoint(base_url) .build(); } here's what's in build.gradle:
dependencies { compile 'com.squareup.retrofit:retrofit:1.9.0' } here's stacktrace:

i've tried code, , buider not recognized way doing.
try this:
public static final string base_url = "http://api.myservice.com"; public restadapter providesrestadapter(gson gson) { return new restadapter.builder() .setendpoint(base_url) .build(); } of course, method goes inside class. think class module/restclient configure api. so, can name class appmodule, restclient or name prefer.
below, tutorials can useful:
