Why is my app not fullscreen

I did the final padding change to 50dp and followed that with no action bar. However when I run my project the output on the avd isnt full screen. However the preview on android studio looks correct. What changed would I need to make?

If you'd like, just a tip... experiment with the Theme.Holo.Ligh.NoActionBar.Fullscreen style. :) It's WONDERFUL for log-in/sign-up screens!

You need to use android:Theme.Holo.Light.NoActionBar in place of android:Theme.Holo.Light.Dialog.NoActionBar. Remove the 'Dialog'.

Beware with the version API, in the styles file we can see...

<!-- Base application theme, dependent on API level. This theme is replaced by AppBaseTheme from res/values-vXX/styles.xml on newer devices. -->

So, if you edit the styles file in res/values the action bar will not dissapear. You need edit the styles file for your API level, on my case res/valuesv14.

If you're sure you did everything correctly while editing styles.xml, try cleaning or re-building your project once. Go to Build -> Clean or Rebuild project. If that doesn't help, post your styles.xml file and AndroidManifest.xml on here and I'll have a look.

Style.xml: <resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Holo.Light.Dialog.NoActionBar">
    <!-- Customize your theme here. -->
</style>

</resources>

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

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

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