Android 使用改进的令牌身份验证

Android 使用改进的令牌身份验证,android,retrofit2,Android,Retrofit2,场景是,我有一个登录活动,它将用户名和密码发送到php rest api,如果响应正常,它将显示一个新活动(这里是一个测试活动) 然后,在新的活动中,使用从登录过程中获得的令牌,我可以通过改装来查询数据库 问题是我需要保存登录尝试中的cookies,以便在下一个请求中使用它。 我正在使用改装:2.2.0和 我读 及 我检查了所有可能的解决方案 我的应用程序正常工作,没有发生错误,但我的第一个和第二个活动中的标题字段值不同 这是我的改装客户端: public class RetrofitClien

我的应用程序正常工作,没有发生错误,但我的第一个和第二个活动中的标题字段值不同

这是我的改装客户端:

    public static Retrofit getRetroftInstance() {

            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
