Production Networking Patterns Deep Dive

Overview

Production patterns: timeouts, security config, monitoring.

Core Concepts

Timeouts prevent indefinite waits: - connectTimeout: 10-30s - readTimeout: 20-60s
- writeTimeout: 20-60s - callTimeout: includes retries

Code Examples

val httpClient = OkHttpClient.Builder()
    .connectTimeout(30, TimeUnit.SECONDS)
    .readTimeout(60, TimeUnit.SECONDS)
    .writeTimeout(60, TimeUnit.SECONDS)
    .callTimeout(120, TimeUnit.SECONDS)
    .build()
// Network Security Config XML
<domain-config>
    <domain includeSubdomains="true">example.com</domain>
    <pin-set>
        <pin digest="SHA-256">...</pin>
    </pin-set>
</domain-config>

Senior-Level Insights

• One OkHttp instance per app
• Connection pool management
• Timeouts must account for network latency
• Production monitoring: latency, errors, bandwidth
