When I run my application, it's automatically create a droid-bot picture on surface of application. So, I want to change a picture, what should I do?

回答1:

(1) create a PNG image (say icon.png) and save it in the folder:

res/drawable 

(2) Then, in AndroidManifest.xml of your application add the icon tag in your application:

android:icon=”@drawable/icon”

e.g.

<application android:name ="yourAppMgr" android:icon="@drawable/icon" 
                //... >

回答2:

AFAIK you can't change the icon of installed application with some completely custom one, but you can add application shortcut with custom image to the home screen from your application.
