Slow app startup will bring bad user experience, cause bad reviews from users, and even uninstall your app. The information provided in this article can help you optimize the startup time of your application. let's first understand the internal principles of application startup. The actual time Beyonce takes the stage has ranged from 8:30 p.m.

Next, we will discuss how to analyze startup performance. #ANDROID MEASURE APP STARTUP TIME HOW TO# Finally, at the end we will introduce some common problems that affect startup performance, and will give corresponding solutions. Application startup principleĪpplication startup can be divided into three types, cold startup, warm startup, and hot startup. The time spent on each type is different. In cold start mode, the application process does not exist at all, and the system needs to create a new application process. In the other two modes, the system only needs to switch the running application from the background to the foreground. It is recommended that you optimize for cold start mode. The cold start speed has been improved, and the warm start and hot start will also become faster.

So during the application startup process, what operations did the Android system and application layer do? Understanding their internal principles will help us optimize the startup performance. A particular issue I need to try and solve right now is painfully long startup times after a deployment to App Service. #ANDROID MEASURE APP STARTUP TIME ANDROID# Im not the most experience Episerver person around, and recently did a migration of our site from Azure Hosted VMs to Azure App Service. Cold startĬold start means that the application is re-created: before the start, the system process has not yet created an application process. Once the system has created the application process, the application process will perform the following steps: A blank startup form is displayed immediately after the app starts.Compared with other startup methods, the cold startup mode requires more initialization operations for the system and applications, so optimization also has certain challenges.Īt the beginning of the cold start, the system needs to perform three tasks: A cold start usually occurs when you open an application for the first time or the system actively kills your application. At this time, the user can use the app.įigure 1 shows the alternate execution process between the system and the application during the startup processįigure 1 shows the important steps of the cold start process Once the application process has finished drawing for the first time, the system process will replace the previously generated background form with Main Activity. Start-up performance problems may occur during application creation and main activity creation. When your application starts, the blank window will always exist until the system completes the first drawing operation of the application. #ANDROID MEASURE APP STARTUP TIME ANDROID#.#ANDROID MEASURE APP STARTUP TIME HOW TO#.
