Embedding Whereby in Android

Learn how to embed Whereby rooms in your native Android app using the WebView class.
We offer native SDKs that allow you to tap into powerful features such as listening to room events and use custom buttons to send commands to the room from your application.

In order to embed a room in Android, add these permissions to the manifest:
XML
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
You will need to use the WebView class. Start by creating a custom WebChromeClient class and override the onPermissionRequest method:
Java
Kotlin
import android.annotation.TargetApi;
import android.app.Activity;
import android.os.Build;
import android.webkit.PermissionRequest;
import android.webkit.WebChromeClient;
​
public class CustomWebChromeClient extends WebChromeClient {
    private Activity activity;
​
    public CustomWebChromeClient(Activity parentActivity) {
        super();
        activity = parentActivity;
    }
​
    @Override
    public void onPermissionRequest(final PermissionRequest request) {
        activity.runOnUiThread(new Runnable() {
            @TargetApi(Build.VERSION_CODES.LOLLIPOP)
            @Override
            public void run() {
                request.grant(request.getResources());
            }
        });
    }
}
import android.app.Activity
import android.webkit.PermissionRequest
import android.webkit.WebChromeClient
​
class CustomWebChromeClient(private val activity: Activity) : WebChromeClient() {
    override fun onPermissionRequest(request: PermissionRequest) {
        activity.runOnUiThread { request.grant(request.resources) }
    }
}
Then, create a WebViewUtils helper class to configure the WebView. Here is a possible configuration:
Java
Kotlin
import android.annotation.SuppressLint;
import android.webkit.CookieManager;
import android.webkit.WebSettings;
import android.webkit.WebView;
​
public class WebViewUtils {
​
    @SuppressLint("SetJavaScriptEnabled")
    public static void configureWebView(WebView webView) {
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webSettings.setDomStorageEnabled(true);
        webSettings.setDatabaseEnabled(true);
        webSettings.setMediaPlaybackRequiresUserGesture(false);
        CookieManager.getInstance().setAcceptCookie(true);
        CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
    }
}
import android.annotation.SuppressLint
import android.webkit.CookieManager
import android.webkit.WebView
​
object WebViewUtils {
    @SuppressLint("SetJavaScriptEnabled")
    fun configureWebView(webView: WebView) {
        val webSettings = webView.settings
        webSettings.javaScriptEnabled = true
        webSettings.domStorageEnabled = true
        webSettings.databaseEnabled = true
        webSettings.mediaPlaybackRequiresUserGesture = false
        CookieManager.getInstance().setAcceptCookie(true)
        CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true)
    }
}
Finally, set up your activity following these steps:
1.Configure the webView.
2.Request the permissions if needed.
3.Add the ?skipMediaPermissionPrompt parameter to the room URL and load it.
Here is an example:
Java
Kotlin
import androidx.annotation.NonNull;
import androidx.annotation.RequiresApi;
import androidx.appcompat.app.AppCompatActivity;
import android.Manifest;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
​
import java.util.ArrayList;
import java.util.List;
​
public class MainActivity extends AppCompatActivity {
​
    public String roomUrlString = ""; // Replace by your own
    private String roomParameters = "?skipMediaPermissionPrompt";
​
    private static final int PERMISSION_REQUEST_CODE = 1234;
    private String[] requiredDangerousPermissions = {
            Manifest.permission.CAMERA,
            Manifest.permission.MODIFY_AUDIO_SETTINGS,
            Manifest.permission.RECORD_AUDIO
    };
​
    private WebView webView;
​
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.webView = findViewById(R.id.webView);
        WebViewUtils.configureWebView(this.webView);
        this.webView.setWebChromeClient(new CustomWebChromeClient(this));
        this.webView.setWebViewClient(new WebViewClient());
    }
​
    @Override
    protected void onResume() {
        super.onResume();
        if (this.webView.getUrl() == null) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && this.isPendingPermissions()) {
                // This explicitly requests the camera and audio permissions.
                // It's fine for a demo app but should probably be called earlier in the flow,
                // on a user interaction instead of onResume.
                this.requestCameraAndAudioPermissions();
            } else {
                this.loadEmbeddedRoomUrl();
            }
        }
    }
​
    private void loadEmbeddedRoomUrl() {
        this.webView.loadUrl(roomUrlString + roomParameters);
    }
​
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        switch (requestCode) {
            case PERMISSION_REQUEST_CODE:
                if (this.grantResultsContainsDenials(grantResults)) {
                    // Show some permissions required dialog.
                } else {
                    // All necessary permissions granted, continue loading.
                    this.loadEmbeddedRoomUrl();
                }
                break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }
​
