Error: Execution failed for task ':app:generateDebugBuildConfig' - android-studio

Question

I'm building an app that uses a Cordova plugin for Google Maps. I keep getting this error and have no clue how to fix it or what it even means. Any help would be appreciated. Here's the error:
* What went wrong:
Execution failed for task ':app:generateDebugBuildConfig'.
> Failed to calculate the value of task ':app:generateDebugBuildConfig' property 'buildConfigPackageName'.
> org.xml.sax.SAXParseException; systemId: file:/C:/Users/Amanda/Desktop/project2/platforms/android/app/src/main/AndroidManifest.xml; lineNumber: 5; columnNumber: 184; The prefix "tools" for attribute "tools:overrideLibrary" associated with an element type "application" is not bound.
And my AndroidManifest.xml:
<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="10000" android:versionName="1.0.0" package="com.example.project2" xmlns:android="http://schemas.android.com/apk/res/android">

Error
org.xml.sax.SAXParseException;
systemId: file:/C:/Users/Amanda/Desktop/project2/platforms/android/app/src/main/AndroidManifest.xml;
lineNumber: 5; columnNumber: 184;
The prefix "tools" for attribute "tools:overrideLibrary" associated with an element type "application" is not bound.
As you can see the error is in line no 5 and column no 184.As suggested i think you are missing the name space
xmlns:tools="http://schemas.android.com/tools"
Add this to your manifest so that your manifest will look something like this
<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true"
android:versionCode="10000"
android:versionName="1.0.0"
package="com.example.project2"

<uses-permission android:name="android.permission.INTERNET" />
<application android:hardwareAccelerated="true" android:icon="#mipmap/ic_launcher" android:label="#string/app_name" android:supportsRtl="true" tools:overrideLibrary="za.co.twyst">
