Introduction: In the evolving landscape of mobile application development, understanding user behaviour, managing user identity, and delivering personalised communication are critical components of a successful digital product. Google provides a suite of powerful tools through Firebase and Google Analytics that help developers build, improve, and grow their applications efficiently. This article explores Google Analytics , Firebase Authentication , Firebase Cloud Messaging (push notifications), and other core Firebase products , along with their practical uses. Google Analytics Google Analytics for Firebase is a free app measurement solution that provides insights on app usage and user engagement. Unlike traditional Google Analytics, this version is tightly integrated with Firebase services, making it highly useful for mobile and cross-platform apps. Key Features: Event tracking : Automatically or manually track user actions like screen views, button taps, purchases, etc. User segm...

It is important to note, you cannot mix AppCompat and Jetpack in the same project. You must convert everything to use Jetpack if you want to upgrade. The support library artifacts are being deprecated and all future development is going into AndroidX , so there's no avoiding this migration. Alan Viverette sums this up nicely: “There won’t be a 29.0.0, so Android Q APIs will only be in AndroidX” The stable release of 28.0.0 will be the final feature release packaged as android.support . All subsequent feature releases will only be made available as androidx-packaged artifacts. Below tips will give you a clearer transition path. The current version of AppCompat (v28.x) is exactly the same as AndroidX (v1.x). In fact, the AppCompat libraries are machine generated by changing maven coordinates and package names of the AndroidX codebase. For example, android.support.v7.app.AppCompatActivity is now androidx.appcompat.app.AppCompatActivity For a complete listi...

64-bit CPUs bring in areas such as artificial intelligence, machine learning, and immersive mobile. Supporting 64-bit prepares the ecosystem for the innovation enabled by the advanced compute capabilities of 64-bit devices, and for future Android devices that only support 64-bit code. Starting August 1, 2019 , all new apps and app updates that include native code must have 64-bit versions as well as 32-bit versions when publishing to Google Play. How am I affected? Your app makes use of native code if it meets any of the following criteria: - Your app makes use of C or C++ code. - Your app links with third-party libraries that contain native code. - Your app is built by a third-party app builder that uses native libraries. Preparing for the 64-bit requirement 1. Inspect your APK or app bundle for native code. You can check for .so files using APK Analyzer. Identify whether they are built from your own code or are imported by an SDK or library that you are using. If y...
