Android Question Manifest - adding hardware acceleration

[JoeR]

How do I add hardware acceleration to the manifest? I added it as per manifest editor screen (SetApplicationAttribute) below and received error message
AndroidManifest.xml:16: error: No resource identifier found for attribute 'hardwareAccelerated' in package 'android'. I did also try reading related posts on this subject.

The reason I am trying to do this is that I am experiencing very slow vertical scrolling with webview on a Galaxy Ace using Android version 2.3.6 Gingerbread. I have read elsewhere that hardware acceleration can improve this.

Manifest Editor

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:hardwareAccelerated, "true") 
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
'End of default text.

android:hardwareAccelerated attribute was introduced in Android v3.0. You are getting this error because you are referencing an old version of android.jar (under Tools - Configure Paths).

However it will not affect your device.
