Android : ClassNotFoundException: Didn't find class "com.google.android.gms.maps.SupportMapFragment" on path

The app has always been working fine until today. I've just updated my phone to 4.4.4 (Cyanogenmod). I've also updated Eclipse' ADT plugin and android SDK to the latest versions.

com.google.android.gms.maps.SupportMapFragment is definitely there under "Android Private Libraries" (screenshot below).

What I have tried: Repeatedly clean google-play-services_lib and my project Close and re-open Eclipse

Here is my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.app"
    android:versionCode="5"

    <permission

        android:protectionLevel="signature" />

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

        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.app.MainActivity"
            android:label="@string/app_name"
            android:configChanges="keyboardHidden|orientation" >

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="xxxxxxxxxxxxxxxxxxxxxxx" />
        <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

        <activity android:name="com.example.app.AboutActivity" >
        </activity>

    </application>

</manifest>

And screenshot showing the class is there:
