    By setting the orientation you want in the manifest...
Example: Add android:screenOrientation="portrait" to the element in the manifest or landscape:
<application android:icon="@drawable/icon"
             android:label="@string/app_name">
    <activity android:name="QRCodeActivity"
              android:label="@string/app_name"
              android:screenOrientation="landscape" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
