[0006] However, this implementation method can cover the black screen through the boot animation program, but due to the high-speed and cyclic execution of actions such as picture decoding and image output during the execution of the animation program, it will take up a lot of CPU resources. The CPU resources will be tight when the system starts within a certain period of time, which will affect the startup speed and efficiency of other modules, and will increase the system startup time.

Embodiment 1
[0024] combined with figure 1 Shown, a kind of Android smart TV prevents the method for starting LOGO and switching black screen of application, it is characterized in that, described method comprises the steps:
[0025] Step 1: Customize the system initialization program and cancel the start of the boot animation program;
[0026] Step 2: Through the state control between the layer management service and the application management service, the display update control of the frame buffer is performed by detecting whether the Home application is started, replacing the black screen during the cover initialization process completed by the boot animation program. The process of detecting whether the Home application is started to perform frame buffer display update control includes the following steps:
[0027] Step 2.1: Customize the application management service. After starting the Home application, notify the layer management service of the name of the Home application through...

The invention discloses a method for preventing a blank screen of a startup LOGO and an application for an Android smart television, which comprises the following steps of: step 1, customizing a system initialization program, and canceling the starting of a starting animation program; and step 2, through state control between the layer management service and the application management service, bydetecting whether the Home application is started to carry out display updating control of the frame cache, replacing a blank screen which is finished by a startup animation program and covers an initialization process; after an Android smart television is started and a LOGO is displayed, customizing a layer management service and an application management service of a system, and controlling a frame buffer refreshing request of each module and each application of the system according to the starting state of a Home application. Meanwhile, due to the fact that a boot animation program is not started, CPU resources are released, more CPU resources are distributed to other modules of the system, the processing speed of the CPU is higher when the system is started, and the system starting time is effectively shortened.
Description
technical field [0001] The invention relates to the technical field of smart TVs, in particular to a method for an Android smart TV to prevent a black screen from starting LOGO and switching between applications. Background technique [0002] Android smart TV booting is mainly divided into three stages: the bootloader stage, the operating system stage, and the Home application startup stage. [0003] The display of the boot LOGO, one is to display it during the boot process; the other is to display it when the operating system is initialized, and then perform other initializations. Both methods are to output the boot LOGO image to the video memory and display it on the screen. show. [0004] However, after the startup LOGO display is completed, since the initialization of the operating system has not been completed, when there are other modules to be initialized, especially the initialization of the hardware modules related to the video memory, the video memory will be refr...
