Google released the Google Analytics SDK for iOS and Android v0.8, with iOS 4 mobile support, and fixes for Android. If you’re an app developer, understanding how users engage with your app is critical to building a successful development and monetization strategy. mobile SDKs enable you to track user activity directly in your native mobile apps — for e.g., you can see what “pages” or panels of your app are most popular or how many clicks a particular button or control generates or gain insight into how users interact with your app to help boost your ad earnings.
For e.g., you may find that users are browsing a significant number of pages that aren’t currently being monetized or that a particular ad unit converts better on certain pages than others. This type of rich usage data is crucial to optimizing the user experience as well as your revenue.
And, all “page view” and event tracking data is viewable in same interface as for tracking website statistics, and integrating it into your app is as simple as adding a few lines to your iOS or Android source code.
