Add MediaRouter API to get presentation display. This new API makes it possible for an application to ask on which Display it should show a Presentation based on the currently selected media route. Also added a new API on DisplayManager to query displays that support a certain category of uses. Improved the documentation of the Presentation class to explain how to choose an appropriate Display for presentation. Bug: 7409073 Change-Id: Iab451215e570ae55f3718fc228303143c800fe51

Fix deadlock. The display manager must never call into the activity manager with its lock held. Make it clear that the adapters are constructed while holding the syncroot lock. Bug: 7377631 Change-Id: I1557313cbb31dcad9b5a46919a88a5a1c1af3e9b

Add new Display API for secure video capabilities. Added a new API to determine whether the display supports protected buffers so that an application can choose a different content stream or change how it decodes the content so that it will be viewable on the display. At present, wifi display does not fully support protected buffers although this may be enhanced in the future. Bug: 6986623 Change-Id: If53a53d72b0ec92753cc4b29f99fcb131e00449b

Make display manager tell input system about viewports. The window manager is no longer responsible for telling the input system about the display viewport. Change-Id: I932882bae55decef55f25093bb2a7ebac1620bb1

More improvements to the display manager. Added more complete support for logical displays with support for mirroring, rotation and scaling. Improved the overlay display adapter's touch interactions. A big change here is that the display manager no longer relies on a single-threaded model to maintain its synchronization invariants. Unfortunately we had to change this so as to play nice with the fact that the window manager wants to own the surface flinger transaction around display and surface manipulations. As a result, the display manager has to be able to update displays from the context of any thread. It would be nice to make this process more cooperative. There are already several components competing to perform surface flinger transactions including the window manager, display manager, electron beam, overlay display window, and mouse pointer. They are not manipulating the same surfaces but they can collide with one another when they make global changes to the displays. Change-Id: I04f448594241f2004f6f3d1a81ccd12c566bf296

Add initial multi-display support. Split the DisplayManager into two parts. One part is bound to a Context and takes care of Display compatibility and caching Display objects on behalf of the Context. The other part is global and takes care of communicating with the DisplayManagerService, handling callbacks, and caching DisplayInfo objects on behalf of the process. Implemented support for enumerating Displays and getting callbacks when displays are added, removed or changed. Elaborated the roles of DisplayManagerService, DisplayAdapter, and DisplayDevice. We now support having multiple display adapters registered, each of which can register multiple display devices and configure them dynamically. Added an OverlayDisplayAdapter which is used to simulate secondary displays by means of overlay windows. Different configurations of overlays can be selected using a new setting in the Developer Settings panel. The overlays can be repositioned and resized by the user for convenience. At the moment, all displays are mirrors of display 0 and no display transformations are applied. This will be improved in future patches. Refactored the way that the window manager creates its threads. The OverlayDisplayAdapter needs to be able to use hardware acceleration so it must share the same UI thread as the Keyguard and window manager policy. We now handle this explicitly as part of starting up the system server. This puts us in a better position to consider how we might want to share (or not share) Loopers among components. Overlay displays are disabled when in safe mode or in only-core mode to reduce the number of dependencies started in these modes. Change-Id: Ic2a661d5448dde01b095ab150697cb6791d69bb5

Add plumbing for new surface flinger display API. Cleaned up the implementation of Surface and SurfaceSession to use more consistent naming and structure. Added JNI for all of the new surface flinger display API calls. Enforced the requirement that all Surfaces created by the window manager be named. Updated the display manager service to use the new methods. Change-Id: I2a658f1bfd0437e1c6f9d22df8d4ffcce7284ca2

Stub out display manager service implementation. Reverting to the previous stub as the display adapter registration and the logical to physical mapping is not at all what we are going to need moving forward. Fixed up the service initialization order so that the display manager service has a context from the start. Change-Id: I717f2f1099c7a77180ef207c371ec8329258850a

Start moving away from DisplayMetrics.DENSITY_DEVICE. This puts in most of the infrastructure needed to allow us to switch between different densities at run time. The main remaining uses of the global are to initialize the Bitmap object (not sure what to do about that since it doesn't have anything passed in the constructor to get this information from), and being able to load drawables if we need a different density than what was preloaded by zygote.

Add display manager skeleton. The purpose of this change is to remove direct reliance on SurfaceFlinger for describing the size and characteristics of displays. This patch also starts to make a distinction between logical displays and physical display devices. Currently, the window manager owns the concept of a logical display whereas the new display manager owns the concept of a physical display device. Change-Id: I7e0761f83f033be6c06fd1041280c21500bcabc0
