Android change Application Title and Icon image

You need to modify the AndroidManifest.xml for this. Change the XML tag as shown below
<application android:icon="@drawable/your_icon" android:label="@string/your_title"
        android:theme="@android:style/Theme.Holo.Light">
        ....
        ....
</application>

Add the your_title in your strings.xml file and drop the your_icon image in the drawable folders ! 

Depending on what API level you are creating your Android application for, in your “res” folder you either have one folder called “drawable” or three folders called “drawable-ldpi”, “drawable-mdpi” and “drawable-hdpi”.
