# Android SDK

## 初始化

```java
new InitConfig.Builder()
    .setContext(context)
    .setPrimaryServiceHost("httpdns-a.example.com")
    .setBackupServiceHost("httpdns-b.example.com")
    .setServicePort(443)
    .setSecretKey("your-sign-secret")
    .setEnableHttps(true)
    .buildFor("app1f1ndpo9");
```

## 解析

```java
HTTPDNSResult result = httpDnsService.getHttpDnsResultForHostSyncNonBlocking(
    "api.business.com",
    RequestIpType.auto,
    null,
    null
);
```

## 官方业务适配器

```java
HttpDnsHttpAdapter adapter = HttpDns.buildHttpClientAdapter(httpDnsService);
HttpDnsAdapterResponse resp = adapter.execute(
    new HttpDnsAdapterRequest("GET", "https://api.business.com/v1/ping")
);
```

固定策略：IP 直连 + 空 SNI + Host=真实域名，不回退到带 SNI。
