How to Add Firebase Analytics to Android App in Android Studio?

Firebase Analytics is a powerful tool for understanding your app's usage and user engagement. Here's a step-by-step guide on how to integrate Firebase Analytics into your Android app using Android Studio:

Set up a Firebase project:
- Go to the Firebase Console.
- Click on "Add Project" and follow the prompts to create a new Firebase project.
Add your Android app to the Firebase project:
- In the Firebase console, click on the Android icon to add an Android app to your project.
- Enter your app's package name.
- Download the google-services.json file when prompted and place it in your app's root directory (app/).

Add Firebase SDK to your app:

In your root-level build.gradle file, make sure you have Google's Maven repository:

buildscript {
    repositories {
        // ...
        google() // This should be already added for most Android Studio projects.
    }
    // ...
}

Add the classpath for the Google services plugin:

buildscript {
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:4.3.8' // Check for the latest version
    }
}

In your app-level build.gradle file, apply the plugin at the bottom of the file:
```
apply plugin: 'com.google.gms.google-services'
```

Add the Firebase Analytics dependency:

dependencies {
    // ...
    implementation 'com.google.firebase:firebase-analytics:19.0.1' // Check for the latest version
}

Initialize Firebase in your app:
Typically, Firebase initializes itself automatically in your app. However, if you ever need to initialize it manually, you can do so by adding the following code in your Application class:
```
import com.google.firebase.FirebaseApp;

public class YourApplicationClass extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        FirebaseApp.initializeApp(this);
    }
}
```

Use Firebase Analytics:

To log events, you can get an instance of FirebaseAnalytics and use its methods:

import com.google.firebase.analytics.FirebaseAnalytics;

// ...

FirebaseAnalytics mFirebaseAnalytics = FirebaseAnalytics.getInstance(this);

// To log an event
Bundle params = new Bundle();
params.putString("item_name", "example_item_name");
mFirebaseAnalytics.logEvent("event_name", params);

Run your app:
After making these changes, run your app. Firebase will automatically start collecting data, and you should see user engagement metrics and any logged events in the Firebase console after a few hours.

Integrating Firebase Analytics in Android Studio:

Description: Integrate Firebase Analytics into your Android Studio project to track user interactions and events.

Code:

// Add the Firebase Analytics dependency in your app-level build.gradle file
implementation 'com.google.firebase:firebase-analytics:20.0.2'

// Initialize Firebase Analytics in your Application class or MainActivity
FirebaseApp.initializeApp(this);

Logging events and user properties with Firebase Analytics:

Description: Log custom events and user properties to capture meaningful data for analysis.

Code:

// Log a custom event
Bundle params = new Bundle();
params.putString("category", "button_click");
params.putString("label", "login_button");
firebaseAnalytics.logEvent("button_click", params);

// Set user properties
firebaseAnalytics.setUserProperty("preferred_language", "en");

Implementing conversion tracking with Firebase Analytics:
- Description: Track conversions or specific user actions that contribute to your app's goals or success.
- Code:
```
// Log conversion event
firebaseAnalytics.logEvent(FirebaseAnalytics.Event.ECOMMERCE_PURCHASE, params);
```

Handling screen views and navigation events in Firebase Analytics:

Description: Log screen views and navigation events to understand how users navigate through your app.

Code:

// Log screen view event
Bundle screenParams = new Bundle();
screenParams.putString(FirebaseAnalytics.Param.SCREEN_NAME, "MainActivity");
screenParams.putString(FirebaseAnalytics.Param.SCREEN_CLASS, "MainActivity");
firebaseAnalytics.logEvent(FirebaseAnalytics.Event.SCREEN_VIEW, screenParams);
