App crashes after setting to Theme.NoTitleBar.Fullscreen

Question

My app will start if I don't take away the title bar but when I do it crashes as soon as it starts.

This is the code I have so far.

?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.v1.solitare"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="19" />

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


        <activity
            android:name="com.v1.solitare.MainActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
            android:screenOrientation="landscape" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

Please help in any way possible. I just picked up Android coding with Eclipse today and I'm very new at it.

Edit: I think I found the LogCat Errors for it:

Answer 1

ActionBarActivity assumes you are using an ActionBar, while Theme.NoTitleBar themes remove the ActionBar (as that is part of the title bar on newer devices and ActionBarActivity assumes you are using a Theme.AppCompat theme which controls styling for the ActionBar).

Change your activity to extend FragmentActivity if you are okay with not having an Action Bar, although as per the Android design docs is a critical component for making your app feel like an Android app (although some would say that games are granted more leeway).
