I have probably completed an app. The icon of the app on the test machine interface displays the default Android icon. I found a simple way to change it.
This is the default icon and it’s pretty cute, but I made a logo myself and it just got so bad.
Open the Androidmanifest.xml file and find the code in application
android:icon="@mipmap/ic_launcher"Press Ctrl + left mouse button to go to the corresponding location
Replace your logo picture in the background as shown in the picture, and put the picture in the drawable-folder
Then it becomes what you want~
