Remove the accessibility focus search code. 1. In JellyBean we have added some APIs to search for next accessibility focus in various directions and set accessibility focus from hover. However, we have decided that there is not clean answer for how this should behave and the APIs were hidden. Now the accessibility service is responsible for that. The unused code is now taken out. 2. This patch also takes out the hidden attribute accessibiligyFocusable since we moved the responsibility for implementing focus search strategy to accessibility services and we did not need that for Jellybean which is a good sign that this is not needed. I general this is one less thing for an app developer to worry about. We can add this if needed later. bug:6773816 Change-Id: I0c858d72c93a2b7ff1f8f35a08d33ec4b9eb85fd

Add the possibility to modify the View focus rect This change makes it possible for a view to supply a different rectangle than the drawing rect to be used by the FocusFinder when finding a new view to give focus to. This is useful if e.g. the total view area is larger than the interactive area of the view. The default implementation of getFocusRect() will return getDrawingRect(). The existing behaviour is only changed if getFocusRect() is overridden by a subclass of android.view.View Change-Id: I52dd95c6fa296b744e354217051dcec1bb3c8e92

Improving accessibility focus traversal. 1. Now the views considered during the accessibility focus search are the ones that would get accessibility focus when thovered over. This way the user will get the same items i.e. feedback if he touch explores the screen and uses focus traversal. This is imperative for a good user experience. 2. Updated which focusables are considered when searching for access focus in ViewGroup. Generally accessibility focus ignores focus before/after descendants. 3. Implemented focus search strategy in AbsListView that will traverse the items of the current list (and the stuff withing one item before moving to the next) before continuing the search if forward and backward accessibility focus direction. 4. View focus search stops at root namespace. This is not the right way to prevent some stuff that is not supposed to get a focus in a container for a specific state. Actually the addFocusables for that container has to be overriden. Further this approach leads to focus getting stuck. The accessibility focus ignores root names space since we want to traverse the entire screen. 5. Fixed an bug in AccessibilityInteractionController which was not starting to search from the root of a virtual node tree. 6. Fixed a couple of bugs in FocusFinder where it was possible to get index out of bounds exception if the focusables list is empty. bug:5932640 Change-Id: Ic3bdd11767a7d40fbb21f35dcd79a4746af784d4

Removing hierarchical accessibility focus directions. 1. The accessibility focus directions are not needed since an accessibility service just get the root, first child, next sibling, previous sibling and call execute the action to give it accessibility focus. Now the accessibility node info tree is properly ordered taking into account layout manager directions for both layout manager that we report and ones that we have determined as not important for accessibility. Also the position of a node info are ordered properly based on their coordinates after all transformations as opposed to child index. bug:5932640 Change-Id: I994a8297cb1e57c829ecbac73a937c2bcbe0bac7

Accessibility focus - framework Usefulness: Keep track of the current user location in the screen when traversing the it. Enabling structural and directional navigation over all elements on the screen. This enables blind users that know the application layout to efficiently locate desired elements as opposed to try touch exploring the region where the the element should be - very tedious. Rationale: There are two ways to implement accessibility focus One is to let accessibility services keep track of it since they have access to the screen content, and another to let the view hierarchy keep track of it. While the first approach would require almost no work on our part it poses several challenges which make it a sub-optimal choice. Having the accessibility focus in the accessibility service would require that service to scrape the window content every time it changes to sync the view tree state and the accessibility focus location. Pretty much the service will have to keep an off screen model of the screen content. This could be quite challenging to get right and would incur performance cost for the multiple IPCs to repeatedly fetch the screen content. Further, keeping virtual accessibility focus (i.e. in the service) would require sync of the input and accessibility focus. This could be challenging to implement right as well. Also, having an unlimited number of accessibility services we cannot guarantee that they will have a proper implementation, if any, to allow users to perform structural navigation of the screen content. Assuming two accessibility services implement structural navigation via accessibility focus, there is not guarantee that they will behave similarly by default, i.e. provide some standard way to navigate the screen content. Also feedback from experienced accessibility researchers, specifically T.V Raman, provides evidence that having virtual accessibility focus creates many issues and it is very hard to get right. Therefore, keeping accessibility focus in the system will avoid keeping an off-screen model in accessibility services, it will always be in sync with the state of the view hierarchy and the input focus. Also this will allow having a default behavior for traversing the screen via this accessibility focus that is consistent in all accessibility services. We provide accessibility services with APIs to override this behavior but all of them will perform screen traversal in a consistent way by default. Behavior: If accessibility is enabled the accessibility focus is the leading one and the input follows it. Putting accessibility focus on a view moves the input focus there. Clearing the accessibility focus of a view, clears the input focus of this view. If accessibility focus is on a view that cannot take input focus, then no other view should have input focus. In accessibility mode we initially give accessibility focus to the topmost view and no view has input focus. This ensures consistent behavior accross all apps. Note that accessibility focus can move hierarchically in the view tree and having it at the root is better than putting it where the input focus would be - at the first input focusable which could be at an arbitrary depth in the view tree. By default not all views are reported for accessibility, only the important ones. A view may be explicitly labeled as important or not for accessibility, or the system determines which one is such - default. Important views for accessibility are all views that are not dumb layout managers used only to arrange their chidren. Since the same content arrangement can be obtained via different combintation of layout managers, such managers cannot be used to reliably determine the application structure. For example, a user should see a list as a list view with several list items and each list item as a text view and a button as opposed to seeing all the layout managers used to arrange the list item's content. By default only important for accessibility views are regared for accessibility purposes. View not regarded for accessibility neither fire accessibility events, nor are reported being on the screen. An accessibility service may request the system to regard all views. If the target SDK of an accessibility services is less than JellyBean, then all views are regarded for accessibility. Note that an accessibility service that requires all view to be ragarded for accessibility may put accessibility focus on any view. Hence, it may implement any navigational paradigm if desired. Especially considering the fact that the system is detecting some standard gestures and delegates their processing to an accessibility service. The default implementation of an accessibility services performs the defualt navigation. bug:5932640 bug:5605641 Change-Id: Ieac461d480579d706a847b9325720cb254736ebe
