We'll correct this in the next section of this step. You will probably see some compilation errors or maybe a warning about a missing google-services.json file. Import the measure-view-performance-start project into Android Studio. If you don't have git on your machine, you can also download the code directly from GitHub. $ cd codelab-measure-android-view-performance This will create a folder called codelab-measure-android-view-performance on your machine: $ git clone

Run the following commands to clone the sample code for this codelab. How to view the collected metrics in the Firebase console.How to instrument custom code traces with metrics to record Slow/Frozen screens.Understanding Screen Rendering and what is a Slow/Frozen frame.

How to instrument custom code traces to measure the load time of an Activity or Fragment.Understanding the loading of an Activity or a Fragment.How to add Firebase Performance Monitoring to an Android app.You can easily extend this codelab to measure performance of Custom View components. So it's often useful to understand how to measure the load time and screen rendering performance of both Activities and Fragments by instrumenting custom code traces in your app. Also, many apps usually implement their own Custom Views for more complex use cases. However, industry apps usually don't have lots of Activities but rather one Activity and multiple Fragments. Doesn't Firebase Performance Monitoring provide these performance metrics out-of-the-box?įirebase Performance Monitoring automatically captures some performance data out-of-the-box, such as your app start time (i.e., the load time for your first Activity only) and screen rendering performance (i.e., slow and frozen frames for Activities but not for Fragments). Slow and frozen screens will directly impair user interaction with your app and create a bad user experience. Users are not able to see the entire content of the UI until it's completely drawn on the screen. For example, your Activity or Fragment contains the UI which holds the View components that users interact with. Views are a key part of Android applications that directly affect the user experience. Last Updated: Why do we need to measure the performance of Views?
