The Android smart television is started mainly in three stages: a bootstrap phase, an operating system phase and a Home application starting phase.
Starting up LOGO, wherein one display is carried out at the stage of a bootstrap program; one method is to display the image when the operating system is initialized and then perform other initialization, and both methods are to output the startup LOGO image to the video memory and display the image on the screen.
However, after the display of the boot LOGO is completed, the initialization of the operating system is not completed, and when other modules are initialized, particularly the initialization of a hardware module related to the memory, the memory can be refreshed and controlled again, so that the image data of the boot LOGO in the memory is refreshed, the boot LOGO image disappears, the Home application is not started at this time, no image output of an application interface exists, and the screen can be in a black screen state.
Android to this problem, the current solution is: in the initialization stage of an operating system of an Android system, a starting animation program is started, the starting animation program outputs a picture frame sequence to a video memory at a high speed through frame buffer circulation, and an animation process is simulated and used for covering a black screen. And when the completion of the start of the Home application is detected, the system forces the boot animation program to exit, and at the moment, the application interface of the Home application is displayed.
However, although the black screen can be covered by the boot animation program, in the process of executing the animation program, since the actions such as picture decoding, image output and the like are executed at a high speed and circularly, a small amount of CPU resources are occupied, the CPU resources are in shortage during system startup in a certain time, the startup speed and efficiency of other modules are affected, and the system startup time is increased.

step 1: customizing a system initialization program, and canceling the starting of a starting animation program;
step 2: through state control between the layer management service and the application management service, and through detecting whether the Home application starts to carry out display updating control of frame cache, black screen in the covering initialization process finished by the starting animation program is replaced.
According to the method, after the Android smart television is started and the starting LOGO is displayed, the layer management service and the application management service of the system are customized, and the frame buffer refreshing requests of all modules and all applications of the system are controlled according to the starting state of the Home application, so that the switching between the starting LOGO and the application interface of the Home application is realized without a black screen, and the visual experience of a user is improved; meanwhile, as the bootinformation animation program is not started, the CPU resource is released, and more CPU resources are allocated to other modules of the system, so that the processing speed of the CPU is faster when the system is started, and the system starting time is effectively reduced.
Preferably, the process of detecting whether the Home application starts to perform the display update control of the frame cache in step 2 includes the following steps:
step 2.1: customizing an application management service, and notifying the layer management service of the name of the Home application in a system attribute mode after the Home application is started;
step 2.2: customizing the layer management service, acquiring the name of the application through the system attribute provided by the application management service when receiving a frame cache updating request, and detecting whether a requester is the Home application;
step 2.3: if the Home application is detected in the step 3, updating the image to a video memory through an updating request and frame caching; if the application is not the Home application, the update request is refused, and the frame cache keeps the original state.
Preferably, when it is detected that the Home application is started and an update request is made, when the layer management service receives the frame cache update request, the layer management service does not judge whether the update request is the Home application, defaults to pass through all the update requests, and when the Home application is started and an update request is made, the process of judging the started update request is omitted, and the time for starting the system is effectively shortened.
Compared with the prior art, the invention has the following advantages and beneficial effects:
(1) according to the method, after the Android smart television is started and the starting LOGO is displayed, the layer management service and the application management service of the system are customized, and the frame buffer refreshing requests of all modules and all applications of the system are controlled according to the starting state of the Home application, so that the switching between the starting LOGO and the application interface of the Home application is realized without a black screen, and the visual experience of a user is improved; meanwhile, as the bootinformation animation program is not started, the CPU resource is released, and more CPU resources are allocated to other modules of the system, so that the processing speed of the CPU is faster when the system is started, and the system starting time is effectively reduced.
(2) When detecting that the Home application is started and has an update request, the layer management service does not judge whether the update request is the Home application when receiving the frame cache update request, defaults to pass all the update requests, and omits the process of judging the started update request when the Home application is started and has the update request, thereby effectively shortening the starting time of the starting system.
