Setting up Firebase in Your Android App

Empowering Android Apps with WebView and Firebase Analytics

Firebase Webview, a powerful tool for Android developers, enables the seamless integration of web content within native Android applications. It allows developers to expand their app’s functionality and create engaging user experiences . This means that developers can use WebView to embed web pages in their apps, without having to force users to open a separate web browser. This powerful tool not only expands the reach of web content but also enhances the user experience by providing a unified and consistent platform for accessing both native and web-based features.

Harnessing the Power of WebView

WebView in Android is a fundamental component that allows developers to display web content within their native applications. It acts as a bridge between the native code of an Android app and the web content it wants to showcase.

Integrating Firebase Analytics for WebView:

To gain valuable insights into user behavior and website usage within the WebView, developers can integrate Firebase Analytics for Firebase (GA4). This powerful analytics platform provides a comprehensive set of tools to track user interactions, measure engagement metrics, and identify trends in website usage.

Implementing Webview in Android

Step 1: Creating a webview layout

First, adding the WebView in the XML layout file. Put the below code and as mentioned in screenshot:


               android:layout_height=“match_parent” />

It’s crucial to optimize the webview settings for performance and user interaction. This includes enabling JavaScript, adjusting the zoom controls, and setting a responsive viewport.

Step 2: Add INTERNET permission to the Manifest File

After adding the Webview in XML, you need to add Internet permissions into the manifest file. Use the below snippet and screenshot as mentioned below:

<uses-permission android:name=“android.permission.INTERNET” />


Step 3: Enable JavaScript using setJavaScriptEnabled()

After adding the permission into the manifest.xml file, to make your WebView visible to JavaScript code running within the WebView, register it as described below:

// Enabled Javascript

WebSettings webSettings = mywebview.getSettings();


mywebview.loadUrl(“https://www.advaana.com/”); // Load URL



                    new AnalyticsWebInterface(this), AnalyticsWebInterface.TAG);

        } else {

            Log.w(TAG, “Not adding JavaScriptInterface, API Version: “ + Build.VERSION.SDK_INT);


        // WebViewClient allows you to handle

       // onPageFinished and override Url loading.

        mWebView.setWebViewClient(new WebViewClient());

        // loading http://www.google.com url in the the WebView.




Step 4: Create a JavaScript Handler (Web Interface)

Now, after registering your webview as above mentioned step, implement a class with method marked AnalyticsWebInterface as mentioned below in the code below, also you can refer to the JavaScriptInterface document

public class AnalyticsWebInterface {
public static final String TAG = “AnalyticsWebInterface”;
private FirebaseAnalytics mAnalytics;
public AnalyticsWebInterface(Context context) {
mAnalytics = FirebaseAnalytics.getInstance(context);
public void logEvent(String name, String jsonParams) {
LOGD(“logEvent:” + name);
mAnalytics.logEvent(name, bundleFromJson(jsonParams));
private void LOGD(String message) {
// Only log on debug builds, for privacy
if (BuildConfig.DEBUG) {
Log.d(TAG, message);
private Bundle bundleFromJson(String json) {
if (TextUtils.isEmpty(json)) {
return new Bundle();

Bundle result = new Bundle();
try {
JSONObject jsonObject = new JSONObject(json);
Iterator<String> keys = jsonObject.keys();

while (keys.hasNext()) {
String key = keys.next();
Object value = jsonObject.get(key);

if (value instanceof String) {
result.putString(key, (String) value);
} else if (value instanceof Integer) {
result.putInt(key, (Integer) value);
} else if (value instanceof Double) {
result.putDouble(key, (Double) value);
} else {
Log.w(TAG, “Value for key “ + key + ” not one of [String,                                   Integer, Double]”);
} catch (JSONException e) {
Log.w(TAG, “Failed to parse JSON, returning empty Bundle.”, e);
return new Bundle();

return result;
 // [END analytics_web_interface]

Step 5: Send Event Data to Native Code (add code to your website)

Now, after setting up all the things, you need to add Javascript functions to forward events and user properties to native code. You have to add the function into your index.html file. The following code shows how to send events to your native code using Javascript Handler function:

Step 6: Log Events in Android Logcat

Now, it’s time to see the events that are reflecting into your Android Logcat. See the below screenshot for your reference:




Step 7: Monitor Events in Firebase DebugView

Let’s look into the Firebase DebugView as well as into the RealTime Analytics whether our events are reflected into the dashboard or not. Screenshots are mentioned below:

Firebase DebugView:


Firebase Webview empowers Android developers to seamlessly integrate web content within their native applications, unlocking a realm of possibilities for creating immersive and engaging user experiences. The integration of Firebase Analytics for Firebase (GA4) further enhances the value of Firebase Webview, enabling developers to gather valuable insights into user behavior and website usage within the WebView. With GA4, developers can track user interactions, identify popular pages, and understand user engagement patterns, allowing them to optimize their apps for enhanced usability and performance. The combination of Firebase Webview and GA4 provides a powerful toolset for Android developers to craft innovative and data-driven applications that cater to the evolving needs of modern users.

The convergence of Firebase Webview and GA4 marks a pivotal moment in Android app development. This powerful combination empowers developers to create applications that are not only visually appealing and functionally robust but also data-driven and personalized. The evolution of technology will amplify the impact of Firebase Webview and GA4 on the trajectory of mobile app development.
