Contact permissions problem in android manifest

I need to set the permission in the manifest to read, I manually edited the manifest after having problems trying to use the android manifest editor. My code is below and is currently proving to be erroneous. Any help appreciated. :)

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="ac.uk.d"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Quiz"
                  android:label="@string/app_name">
            <intent-filter>
                <开发者_高级运维action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="7" />
    <uses-permission android:name="android.permission.READ_CONTACTS"/>
</manifest>

The issue is that you have not cleaned the project. To clean the project, select 'Project' on the top menu bar then you'll find clean upon which you clean the selected project or clean all projects as per your needs..
