Facebook introduced Facebook Analytics for Apps, a platform that unifies analytics across multiple devices and platforms In this post, we will take a high-level view of integrating Facebook Analytics in Android application. For More Facebook Analytics details, refer official Facebook Analytics Page To Use the Facebook Analytics feature in our apps we need to Enable this feature. To do this follow these steps Step 1: Create a New app a Facebook Portal by following this link https://developers.facebook.com/products/analytics/quickstarts/android/ Step 2: Add Facebook SDK to the Android project. buildscript { Now open app-level Gradle file and Facebook SDK dependencies Step 3: Now we need to add Facebook APP ID open string file in project copy your app id from the Facebook portal and paste it in string Now update manifest.xml file by adding internet permission and Facebook APP id like below Step 4: Now we need to add our Android project details in App created in Facebook Portal Here we need to Application Package Name and MainScreen of application. Now we need to add HashKey for the Created application. The HashKey having 28 length How to create HashKey for Android application for Facebook integration? We can Generate HashKey in two ways. If you want it for production build add your Released Keystore file. We can also Generate HashKey in Android by programmatically Step 5: Verify App Events Now we can verify app events at Events Manager by running the application Events Manager will take 20 minutes to show events on the dashboard. How to add Facebook Log Events Facebook Events are categorized in to below categories Also have few Auto-logged Events Install App Journey Launch App See More Facebook Events at https://developers.facebook.com/docs/analytics/send_data/events Sample Code MainActivty.kt manifest.xml Resize and Crop Image in Android Kotlin Dependency Injection - What is Dependency Injection One to One Chat Application in Kotlin Related Topics
