Stop Android Studio from using Support Library

I'm surprised no one can still give you a straight forward answer. I hope my response will help.

So to stop Android Studio from using support library especially the infamous AppCompat v7, follow these few steps:

1) Gradle Scripts > build.gradle(Module: app)

2) Remove the line that says compile 'com.android.support:appcompat-v7:22.1.1'

3) res/values/styles.xml > change the parent value to: parent="@android:style/Theme.Holo.Light"

4) AndroidManifest.xml > change the application android:theme to: android:theme="@android:style/Theme.Holo.Light"

5) Go into your activities and remove the line that imports the support library. Change it to: import android.app.Activity;

6) Now in the menu bar: Build > ReBuild Project. Correct any errors then keep rebuilding until you get it to work, then run your project to ensure nothing crashes and your references are in order.

For me I got errors stating that I app:ShowAsAction is not supported or so. I had to change it to android:ShowAsAction. Just Make sure that for any error, you read it carefully and follow the suggestions in the little dialogues boxes that pop up beside the error line.
