Let's create an icon for our application!
Open Android Asset Studio and choose "Launcher icons".
Create an image of your choice and download the zip file. Opening the file you will see that there's several images inside qualified folders. Move each of these images into the correct folders and add qualified folders that don't currently exit. Override the existing icons when prompted.
Note: The tool doesn't provide a resource for
drawable-ldpi.
We already have this file name specified in the manifest, so we won't need to update the file. In general, If you want to add an icon, add it to the <application/> tag:
<application
android:label="@string/app_name"
android:icon="@drawable/ic_launcher">
