android - 使用 OkHttp 没有并发（网络调用按顺序执行）

问题描述

我com.squareup.okhttp3:okhttp:4.9.1在 Java Android 应用程序中使用 OkHttp ( )。

我的假设是可以使用OkHttpClient. 然而，情况似乎并非如此——这些调用对我来说是按顺序执行的。

这是我的设置：

Dispatcher dispatcher = new Dispatcher();

// for an unclear reason this sill does not allow concurrent calls
dispatcher.setMaxRequestsPerHost(32);

OkHttpClient httpClient = new OkHttpClient.Builder()
    .addInterceptor(
        new HttpLoggingInterceptor(s -> Log.d("KeyValueStorage", s))
            .setLevel(HttpLoggingInterceptor.Level.BODY)
    )
    .eventListenerFactory(new LoggingEventListener.Factory())
    .connectTimeout(10, TimeUnit.SECONDS)
    .readTimeout(10, TimeUnit.SECONDS)
    .writeTimeout(10, TimeUnit.SECONDS)
    .dispatcher(dispatcher)
    .build();

以下是日志：

日志显示了我如何使用相同的OkHttpClient. 令我惊讶的是，它们根本没有交错。

我尝试过的想法（没有成功）：
