If we simply switch to a Release configuration and deploy and run the app again: ActivityTaskManager: Displayed /.MainActivity: +806ms There is some overhead in starting/connecting the debugger, as well as missing optimizations from a Debug build.

The above log messages were captured while debugging an application from Visual Studio on an x86 Android emulator.

Note for Windows users: you will either need adb.exe in your %PATH% or add a powershell alias. On Windows, you could instead run the following powershell: > adb logcat -d | Select-String Displayed Alternatively, you can use the Android Debug Log in Visual Studio.įor example, you could run the following on macOS: $ adb logcat -d | grep DisplayedĪctivityTaskManager: Displayed /.MainActivity: +2s494ms You can use adb logcat to quickly view the Android device log at the command-line. On Android, the ActivityManager system process displays a “time to initial display” log message that gives the best picture of overall startup time. The process should be: measure, make changes, measure again, repeat. Blindly making performance changes may not make as much difference as you hoped, and complicated performance improvements can even hurt the maintainability of your codebase. If your goal is to improve your mobile application’s performance, the very first step should be to actually measure where things are. We’ll look at a few examples of diagnosing performance problems. Additionally, Xamarin.Android has specific tooling for measuring the performance of managed (C#) code. You can measure performance in Xamarin.Android applications in the same way as if developed with Java or Kotlin in Android Studio. They may get frustrated, abandon their shopping cart, or uninstall the app completely if kept waiting for too long. Users don’t want to see a splash screen for 10 seconds when using any app. Poor performance can be a huge detriment to a mobile application’s success.
