Put your uses-permission line after uses-sdk that is

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.pilot.clicker"
    android:versionCode="1"
    android:versionName="1.0">

 <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

<!-- Required -->
    <uses-permission android:name="android.permission.INTERNET"/>
