This projects aims to provide a reusable action bar widget. The action bar replaces the default title and is therefor located at the top of the screen. The action bar highlights important actions. The action bar pattern is well documented over at Android Patterns. The action bar widget is an Library Project. This means that there's no need to copy-paste resources into your own project, simply add the action bar widget as a reference to your existing project.

The action bar: is located at the top of the screen to support navigation and highlight important functionalities replaces the title bar (which is often included into it) is best used for actions across your app, like search, refresh and compose can provide a quick link to app homeby tapping the app logo is preferably not contextual, but actions can differ from page to page

Use when You want to bring key actions on screen, so they are in sight. You don't want to hide them under the menu-button. The action bar is best used for common actions like search, refresh and compose. When screen real estate is valuable, consider putting actions in the options menu.

<!-- Variation on the Light theme that turns off the title --><style name="Theme.IOSched" parent="android:style/Theme.Light">    <item name="android:windowNoTitle">true</item>    <item name="android:windowContentOverlay">@null</item></style>

The android:windowContentOverlay is your shadow, and setting it to @null in your theme will eliminate it. You can see this in action in the Google I|O 2010 conference app, which uses many of the same UI conventions as does the new Twitter app. However, right now, the Twitter app has not yet been open-sourced, which is why I point you to the I|O app. The code fragment above is from that app's styles.xml resource.

Additionally, you can feel free to use the Search bar selection mechanism as a replacement for tabs since it’s really just a fast pivot on a data set. If you have more than 3 data sets, tabs become problematic since no more than 3 can be onscreen at once. For example, look at how we implemented the Profile switching mechanism below:

The good news for developers is you get this highly functional contacts feature for free if users choose to sync contact information into your app

The good news for developers is you get this highly functional contacts feature for free if users choose to sync contact information into your app. QuickContact for Android provides instant access to a contact's information and communication modes.

The concept of ActionBar has been introduced with the Twitter application for Android. More recently, we have seen this widget in the Google I/O 2010 schedule application. To sum up, an ActionBar can be considered as an advanced title bar that is capable of: containing several ActionBaritems (similar to buttons) being styled so that the general look’n'feel of the application is in accordance with the underlying brand/visual identity containing a title to show the user a summary of the screen content featuring several user interaction pattern.

Consumers want immediate access to what’s relevant and QR codes are being used to make that possible.

Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix barcodes that can hold thousands of alphanumeric characters of information. Their ability to hold more information and their ease of use makes them practical for small businesses.

When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser.

Split out many internal classes into top-level classes. Removed unnecessary class (ActionList). Added support for fetching a specific Action (View) from the bar by index. Minor syntactic changes to improve performance.
