Error in Compiling : Android Studio

问题

I am trying to modify an existing android project built on IntelliJ. I have searched and tried many things but still my error doesn't go :\

Error:(5, -1) android-apt-compiler: [main] D:\android\tinynote\app\src\main\res\values\theme.xml:5:      
error: Error retrieving parent for item: No resource found that matches the given name 
'@style/Theme.AppCompat'.

What can I do ? Thanks in advance.

Specifically, error is in theme.xml

<?xml version="1.0" encoding="utf-8"?>

<resources>

 <style name="Theme.Bootstrap.Dark" parent="@style/Theme.AppCompat">
    <item name="android:windowBackground">@color/pager_background</item>
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
</style>

<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.ActionBar.Solid">
    <item name="background">@drawable/actionbar_background</item>
    <item name="android:background">@drawable/actionbar_background</item>
</style>

Try adding

dependencies { 
compile 'com.android.support:appcompat-v7:20.+' 
}

to your build.gradle file
