+# HTTPDNS Android SDK (SNI Hidden v1.0.0)
+
+## 1. Init
+
+```java
+import com.newsdk.sdk.android.httpdns.HttpDns;
+import com.newsdk.sdk.android.httpdns.HttpDnsService;
+import com.newsdk.sdk.android.httpdns.InitConfig;
+
+String appId = "app1f1ndpo9";
+
+new InitConfig.Builder()
+    .setContext(context)
+    .setServiceUrl("https://httpdns.example.com:8445")
+    .setSecretKey("your-sign-secret") // optional if sign is enabled
+    .buildFor(appId);
+
+HttpDnsService httpDnsService = HttpDns.getService(appId);
+```
+
+## 2. Resolve
+
+```java
+HTTPDNSResult result = httpDnsService.getHttpDnsResultForHostSyncNonBlocking(
+    "api.business.com",
+    RequestIpType.auto,
+    null,
+    null
+);
+```
+
+## 3. Official HTTP Adapter (IP + Empty-SNI + Host)
+
+```java
+import com.newsdk.sdk.android.httpdns.network.HttpDnsAdapterOptions;
+import com.newsdk.sdk.android.httpdns.network.HttpDnsAdapterRequest;
+import com.newsdk.sdk.android.httpdns.network.HttpDnsAdapterResponse;
+import com.newsdk.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`
