No matching client found for package name (Google Analytics) - multiple productFlavors & buildTypes

📝👋 Hey there tech enthusiasts! Are you facing some trouble setting up Google Analytics for your app? 📊📱 Don't worry, you're not alone! Many developers encounter the dreaded "No matching client found for package name" error when dealing with multiple product flavors and build types. But fear not! In this blog post, we'll address common issues and provide easy solutions to get you up and running with Google Analytics in no time. Let's dive in! 🏊‍♀️

The Problem: 🙄

So, you have multiple product flavors and build types in your app, and things work fine when you select the Build Variant with the correct applicationId. But as soon as you switch to another variant with a different applicationId, you encounter the dreaded error message:

Error:Execution failed for task ':app:processAllcategoriesDebugfreeGoogleServices'.
No matching client found for package name 'com.my.app.package.name.debug'

What's Going On? 🤷‍♂️

Let's break down the error message a bit. In this particular case, Debugfree is the custom build type, and Allcategories is one of the product flavors. The error is caused by the mismatch between the applicationId (package name) specified in your google-services.json file and the one associated with your selected variant. This creates a perplexing situation: how can you work around this issue? 🤔

Solution 1: Dynamic google-services.json ⚙️

One way to tackle this problem is by having a dynamic google-services.json file that adapts to the selected variant. Instead of having a single google-services.json file in the app folder, you can create separate flavor-specific source sets and place the respective google-services.json files there. This way, each variant will pick up the correct configuration automatically. 🔄

Solution 2: Single google-services.json For All Flavors 📂

Alternatively, if you prefer to keep a single google-services.json file for all flavors, you can achieve this by utilizing Gradle tasks. You can create a task to copy the required google-services.json file to the app folder based on the selected variant. This way, you won't need multiple configuration files cluttering your project. 📥

Solution 3: Adding Multiple Package Names 🎯

You might have noticed the package_name field in the google-services.json file, which contains your package name: com.my.app.package.name. Although the documentation doesn't provide explicit instructions, you can manually add multiple package names to this field to cover all your build variants. However, exercise caution and ensure that each package name corresponds to a valid variant configuration. 📦

Conclusion and Call-to-Action 💡

Setting up Google Analytics with multiple product flavors and build types can be tricky, but with the right approach, you can conquer this challenge! Whether you choose a dynamic google-services.json, a single file for all flavors, or adding multiple package names manually, you now have the tools to overcome the "No matching client found for package name" error. 🎉
