Abstract: The subject matter of this specification can be embodied in, among other things, a method that includes receiving at a computing device that is in a locked state, one or more user inputs to unlock the device and to execute at least one command that is different from a command for unlocking the device. The method further includes executing in response to the user inputs to unlock the device an unlocking operation by the device to convert the device from a locked state to an unlocked state. The method further includes executing the at least one command in response to receiving the user inputs to execute the at least one command. The at least one command executes so that results of executing the at least one command are first displayed on the device to a user automatically after the device changes from the locked state to the unlocked state.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating a dynamic mesh for rendering with a graphical user interface. Graphical objects are rendered onto a layer having transparent pixels. The system infers what areas of the layer are drawn areas, and a mesh is generated based on the drawn areas.

Abstract: Aspects of the subject technology relate to systems and methods for constraints-based layout and control of user interface (UI) elements. The system receives a first user input indicating an instruction to position a first UI element on a page of the layout application. The system receives a second user input indicating an instruction to position a second UI element on the page. The system receives a third user input indicating an instruction to create a connection from the second UI element to the first UI element. The system generates a layout constraint indicating a spatial relationship between the first UI element and the second UI element based on the connection. The system provides the layout constraint in a layout data file associated with the UI.

Abstract: The subject matter of this specification can be embodied in, among other things, a method that includes receiving at a computing device that is in a locked state, one or more user inputs to unlock the device and to execute at least one command that is different from a command for unlocking the device. The method further includes executing in response to the user inputs to unlock the device an unlocking operation by the device to convert the device from a locked state to an unlocked state. The method further includes executing the at least one command in response to receiving the user inputs to execute the at least one command. The at least one command executes so that results of executing the at least one command are first displayed on the device to a user automatically after the device changes from the locked state to the unlocked state.

Abstract: A computer-implemented user interface method includes displaying on a mobile device desktop a background image and one or more foreground items over the background image, receiving a user input to pan across the desktop, and panning the background images and one or more foreground images in a parallax manner relative to each other.

Abstract: An example method includes outputting, by a computing device and for display in a graphical development environment used during development of a software application, a graphical user interface associated with the software application, receiving, by the computing device, a development specification that associates a region of the graphical user interface with one or more candidate graphical objects for insertion into the graphical user interface, and receiving, by the computing device, an indication of a selection of the region of the graphical user interface. The example method further includes determining, by the computing device, based at least in part on the development specification and the indication of the selection of the region of the graphical user interface, a graphical object from the one or more candidate graphical objects, and outputting, by the computing device and for display at the region of the graphical user interface, an indication of the graphical object.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing a display list. Graphics processing commands are identified for generation of one or more graphical images on a computer device. During an initial recording of a graphics display list to include the graphics processing commands, if a sub-list of the display list is determined to not include any drawing commands, the display list is recorded so that commands on the sub-list are not executed when the display list is executed.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for defining a sequence of animations for changing visible and non-visible values of objects. One or more programmatic calls is received, the calls including animations and sequencing for their performance. Consecutive frames of the animations are displayed according to the animations and the sequencing defined in the programmatic calls. Non-displayed properties of the objects in the animations are changed in coordination with the displaying of the consecutive frames.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for software fallback upon detecting an error in hardware accelerated rendering. A display of an application is rendered using hardware acceleration. In response to detecting an error in the hardware accelerated rendering of the display, hardware acceleration is disabled for further rendering of the display. Subsequent to disabling the hardware acceleration for further rendering of the display, the display is rendered without hardware acceleration.

Abstract: Display of on-screen elements is coordinated, which includes generating a graphical wallpaper representation in a first process on a first visual layer on a display of a computing device, generating one or more graphical objects in a second process on a second visual layer of the display, wherein the second visual layer is positioned visually on top of the first visual layer, receiving user interactions with the one or more graphical objects and generating information that reflects the user interactions, and communicating the generated information to the first process.
