Theming the ActionBarSherlock in Android

If you want to customize your ActionBarSherlock follow this steps:

1. Create in values folder a new file style.xml

2. In style.xml file determine your styles you want for ActionBarSherlock e.g. :

<?xml version="1.0" encoding="UTF-8"?>

<resources xmlns:android="http://schemas.android.com/apk/res/android">

    <style name="Theme.Styled" parent="Theme.Sherlock.Light.DarkActionBar">

    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>

    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>

</style>

<style name="Widget.Styled.ActionBar" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">

    <item name="background">@drawable/bgraund</item>

    <!-- <item name="android:background">@drawable/top_bar</item> -->

    <item name="backgroundSplit">@drawable/bgraund</item>

    <item name="android:background">@drawable/bgraund</item>

</style>

</resources>

3. In your AndroidManifest.xml determine this your custom style that you just created in style.xml:

<application android:icon="@drawable/adsurfer_icon" 

        android:label="@string/app_name"

        android:debuggable="true"

        android:name=".app.AdsurferApplication"

        android:theme="@style/Theme.Styled" >

Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties

In order to fix this error:

1. Go to the Properties for your project (double click on your project), then find out Adroid Tools/Project Properties (see screenshot)

2. Then change Compile Compiance level to the higher level e.g 1.5 or 1.6 (That is it :) )

What is better Youtube or Vimeo

As I've understood from this article http://webtrends.about.com/od/profiles/a/Vimeo-Vs-Youtube-Video-Sharing-Sites.htm Youtube is still convenient for majority of my needs :) But if I have to publish some creative movie/clip I would prefer Vimeo.
