### Install Web3Auth Android SDK (Groovy)

Source: https://github.com/web3auth/web3auth-android-sdk/blob/master/README.md

Instructions for adding the Web3Auth Android SDK dependency to your project. It requires adding the JitPack repository to your project-level `settings.gradle` and the SDK dependency to your app-level `build.gradle`.

```Groovy
dependencyResolutionManagement {
     repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
     repositories {
         google()
         mavenCentral()
         maven { url "https://jitpack.io" } // <-- Add this line
     }
}

implementation 'com.github.web3auth:web3auth-android-sdk:9.0.0'
```

### Initialize and Login with Web3Auth Android SDK (Kotlin)

Source: https://github.com/web3auth/web3auth-android-sdk/blob/master/README.md

Demonstrates how to initialize the Web3Auth SDK with necessary options like client ID, network, and redirect URL. It also shows how to handle user login using a specified provider and manage the login callback, including handling results when the app is active or not alive.

```Kotlin
import com.web3auth.core.Web3Auth
import com.web3auth.core.types.Web3AuthOptions
import com.web3auth.core.types.Provider
import com.web3auth.core.types.LoginParams
import com.web3auth.core.types.Web3AuthResponse
import android.net.Uri
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import android.widget.Toast
import android.content.Intent
import java.util.concurrent.CompletableFuture

class MainActivity : AppCompatActivity() {
    private lateinit var web3Auth: Web3Auth

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        web3Auth = Web3Auth(
            Web3AuthOptions(
                context = this,
                clientId = "YOUR_WEB3AUTH_CLIENT_ID", // Pass over your Web3Auth Client ID from Developer Dashboard
                network = Network.MAINNET,
                redirectUrl = Uri.parse("{YOUR_APP_PACKAGE_NAME}://auth"),
            )
        )

        // Handle user signing in when app is not alive
        web3Auth.setResultUrl(intent?.data)
    }

    override fun onResume() {
        super.onResume()
        if (Web3Auth.getCustomTabsClosed()) {
            Toast.makeText(this, "User closed the browser.", Toast.LENGTH_SHORT).show()
            web3Auth.setResultUrl(null)
            Web3Auth.setCustomTabsClosed(false)
        }
    }
    
    override fun onNewIntent(intent: Intent?) {
        super.onNewIntent(intent)

        // Handle user signing in when app is active
        web3Auth.setResultUrl(intent?.data)
    }

    private fun onClickLogin() {
        val selectedLoginProvider = Provider.GOOGLE   // Can be Google, Facebook, Twitch etc
        val loginCompletableFuture: CompletableFuture<Web3AuthResponse> = web3Auth.login(LoginParams(selectedLoginProvider))
        
        loginCompletableFuture.whenComplete { _, error ->
            if (error == null) {
                // render logged in UI
            } else {
                // render login error UI
            }
        }
    }
}
```
