Android 每次启动应用程序时运行一段代码，但在应用程序最小化和重新打开时不运行

Question

Need to run a piece of code when the app each time the app is started and not while it is running or and not when main activity is navigated away from and returned to

just need to run the code once on when the app starts up

Answer 1

Without knowing more about your actual use case, the only thing that I can suggest is -

• Override attachBaseContext() in your Application class (Create one if you don't have it)

• Call super.attachBaseContext()

• Write the code you need to run in the method body. (As always, for any long-standing or db/network operations, don't do it on the main thread)

attachBaseContext() is one of the first things to be called when your app is launched so I think this should work for you.
