Selector does not work with mipmap image in android
<p>All I want is that an imagebutton which changes to another image when user press the button on. Following is my directory list. As you see I don't have drawable-hdpi, drawable-mdpi ..and others. And also I can't see mipmap-hdpi, mipmap-mdpi ..and others. My problem is I can't add selector xml for my imagebutton.

Following image is my content_main file which known as activity_main.

My program shows the image of button but when I add  android:background="@drawable/fbpressed" code piece in content_main, the program fails. it says unfortunately Login2 has stopped!</p>

<p>I tried lots of combination for my selector file which is fbpress.xml. like I tried android:icon="@mipmap/facebook_pressed" but it fails again and again. any idea?</p>
