HTTPDNS Android SDK (SNI Hidden v1.0.0)

1. Init

import com.alibaba.sdk.android.httpdns.HttpDns;
import com.alibaba.sdk.android.httpdns.HttpDnsService;
import com.alibaba.sdk.android.httpdns.InitConfig;

String appId = "app1f1ndpo9";

new InitConfig.Builder()
    .setContext(context)
    .setPrimaryServiceHost("httpdns-a.example.com")
    .setBackupServiceHost("httpdns-b.example.com")
    .setServicePort(443)
    .setSecretKey("your-sign-secret") // optional if sign is enabled
    .setEnableHttps(true)
    .buildFor(appId);

HttpDnsService httpDnsService = HttpDns.getService(appId);

2. Resolve

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

3. Official HTTP Adapter (IP + Empty-SNI + Host)

import com.alibaba.sdk.android.httpdns.network.HttpDnsAdapterOptions;
import com.alibaba.sdk.android.httpdns.network.HttpDnsAdapterRequest;
import com.alibaba.sdk.android.httpdns.network.HttpDnsAdapterResponse;
import com.alibaba.sdk.android.httpdns.network.HttpDnsHttpAdapter;

HttpDnsHttpAdapter adapter = HttpDns.buildHttpClientAdapter(
    httpDnsService,
    new HttpDnsAdapterOptions.Builder()
        .setConnectTimeoutMillis(3000)
        .setReadTimeoutMillis(5000)
        .setRequestIpType(RequestIpType.auto)
        .setAllowInsecureCertificatesForDebugOnly(false)
        .build()
);

HttpDnsAdapterResponse response = adapter.execute(
    new HttpDnsAdapterRequest("GET", "https://api.business.com/v1/ping")
);

Behavior is fixed:

• Resolve by /resolve.
• Connect to resolved IP over HTTPS.
• Keep Host header as business domain.
• No fallback to domain direct request.

4. Public Errors

• NO_IP_AVAILABLE
• TLS_EMPTY_SNI_FAILED
• HOST_ROUTE_REJECTED
• RESOLVE_SIGN_INVALID

5. Removed Public Params

Do not use legacy public parameters:

• accountId
• serviceDomain
• endpoint
• aesSecretKey
