Android Manifest . The markup in the document following the root element must be well formed

I have looked through other questions regarding the same problem but was unable to find a helpful solution. Here is my xml . What is wrong with it?

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://ift.tt/nIICcg"
package="com.example.projextxy"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="21" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".LogInActivity"
        android:label="@string/title_activity_log_in"
        android:parentActivityName="com.example.projextxy" >
    </activity>
    <activity
        android:name=".SignUpActivity"
        android:parentActivityName="com.example.projextxy"
        android:label="@string/title_activity_sign_up" >
    </activity>
</application>
