Android：重新启动应用程序时出现白屏

Question

I have a problem of white screen when I relaunch background app.

I click home button and then I click on app logo, my application resume and sometimes I have a white screen.

Do you know what's happening please?

Answer 1

This is the time that your application takes starting, before first activity is displayed.

If you extended the application class, you can look at the onCreate method, if there is much code here.

You can minimize the effects, setting the default window background to a color or drawable in a theme:

<item name="android:windowBackground">@color/mycolor</item>
