How to change the icon of application on Android

If you have to change the icon of your application for Android mobile phone do this:

Edit AndroidManifest.xml file:

<application android:icon="@drawable/ic_launcher" android:label="@string/app_name"

In this example "ic_launcher" is the name of the image of your icon (don't add here its extension e.g. ".png").
