Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, prompting text information in the status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

The event manager can be used for judging whether the touch coordinate of the touch operation of the user is in the first area or not under the condition that the first control mode is started. If so, reporting the touch operation event to an application program layer; if not, no processing is carried out on the touch operation.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), and the like.

The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, and the like.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing. The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

In the following, with reference to the captured photographing scene, the workflow of the software and hardware of the electronic device 100 in the case that the first control mode is turned on is exemplarily described.

When the first control mode is turned on, when the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, timestamp of the touch operation, and other information). The raw input events are stored at the kernel layer. The application framework layer acquires the original input event from the kernel layer, and the event manager judges whether the touch coordinate is in the first area. If so, identifying a control corresponding to the original input event, taking the touch control operation as a touch click operation, taking the control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through a camera 193. If not, no processing is carried out on the original input event.

S302, the first device starts to start a window of the first application.

S303, the first device checks whether the first application on the second device has been started. If the first application on the first device is not started, the first device executes all processes of starting the window of the first application. If the first application on the first device has been launched, S304 is performed.

S304, the first device checks whether a window of the first application of the second device has been launched. If the second device does not start the window of the first application, S305 is performed. If the second device has launched the window of the first application, S306 is performed.

S305, the first device acquires the process information of the first application of the second device. And starting the first application according to the process information, so that the first device can multiplex the process information of the first application of the second device to start the first application, thereby improving the speed of starting the first application.
