My Text Justify is giving me blank page

I wrote an application to make the text justified, the problem is, the page is always blank, I used three methods but the page is still blank and not showing the text, I thought the problem is from the Manifest.xml (PageAbus is the page that comes blank)

<manifest xmlns:android="http://ift.tt/nIICcg"
    package="com.f.fa"
    android:versionCode="1"
    android:versionName="1.0" >

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

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        <activity
            android:name=".PageAbus"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
        </activity>
    </application>
</manifest>

Can you help?
