# Using Android SDK

Embedded Wallets provides a comprehensive set of functions to handle authentication, user management, and blockchain interactions in your Android applications. These functions allow you to implement features like user sign-in, Multi-Factor Authentication (MFA), private key retrieval, and Wallet Services with minimal effort. Each function is designed to handle a specific aspect of Embedded Wallets' functionality, making it easy to integrate into your Android projects.

## `getWeb3AuthResponse()`[​](#getweb3authresponse "Direct link to getweb3authresponse")

The `getWeb3AuthResponse()` method returns the full `Web3AuthResponse` from the current session. This gives you direct access to all session data including keys, user info, signatures, and factor keys.

```
val response = web3Auth.getWeb3AuthResponse()

```

warning

`getWeb3AuthResponse()` throws an `Error` with code `NOUSERFOUND` when no active session exists. Check for an active session using `getPrivateKey().isNotEmpty()` before calling this method.

For most use cases, prefer the typed methods (`getPrivateKey()`, `getEd25519PrivateKey()`, `getUserInfo()`) which provide a more ergonomic API with clear error messages.
