仅在某些Android设备上引发java.net.SocketTimeoutException

我正在尝试从Android设备上载JPEG图像文件。我正在使用square/okhttp库来创建请求。我在Lenovo Yoga平板电脑上遇到此问题，当我尝试上传图像时，出现以下异常。但是，当我在Samsung Galaxy Tab 10“上运行相同的代码时，一切正常，并且图像成功上传。

相机会捕获图像并将其存储在/ storage / emulated / 0 /中，应用将从此处将其拾取并尝试上传。我有一个在后台运行的服务进行上传。

final MediaType MEDIA_TYPE_IMAGE_JPEG = MediaType.parse("image/jpeg");

        File file = new File(path);
        Request request = new Request.Builder()
                .url(baseUrl)
                .addHeader("timestamp", map.get("timestamp"))
                .addHeader("Content-Type", map.get("Content-Type"))
                .post(RequestBody.create(MEDIA_TYPE_IMAGE_JPEG, file))
                .build();

        OkHttpClient client = new OkHttpClient();
        Response response = client.newCall(request).execute();

例外：

您必须增加服务器端的读/写超时。Android的临时解决方法是增加OkHttp3客户端的默认超时：

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(60, TimeUnit.SECONDS)
        .writeTimeout(120, TimeUnit.SECONDS)
        .readTimeout(60, TimeUnit.SECONDS)
        .build();
