Embodiment Construction

[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] The invention provides a booting method, which is applied to an intelligent device.

[0050] refer to figure 1 , figure 1 It is a flowchart of an embodiment of the boot method of the present invention. In this embodiment, the boot method includes the following steps:

[0051] S10: Start ActivityManagerService in the SystemServer process created by Zygote;

[0052] S20: ActivityManagerService sends a custom BOOT_P for starting the first priority system service or system application 0 broadcast;

[0053] S30: In the custom BOOT_P 0 After the preset time after the broadcast is sent, send a custom BOOT_P for starting the second priority system service or system application 1 broadcast;

[0054] S40: In the custom BOOT_P 1 After the preset time after the broadcast is sent, send the source ACTION_BOOT_COMPLET...

Abstract

The invention provides a boot method, a boot device and an Android intelligent device. The method comprises the following steps of starting ActivityManagerService in a SystemServer process created by a Zygote process in a boot process; sending custom BOOT-P0 broadcast for starting a system service or a system application with the first priority in a FinishBooting function or other processes by the ActivityManagerService; after the custom BOOT-P0 broadcast is sent for the preset time, sending custom BOOT-P1 broadcast to start a system service or an application whose boot priority is next only to the system service or application started by the BOOT-P0 broadcast; and after the custom BOOT-P1 broadcast is sent for the preset time, sending original ACTION-BOOT-COMPLETED broadcast for starting a third-party application and / or a system service with third priority. The custom BOOT-P broadcast can be increased according to the number of the system services which need to be started, so that the applications or the services to be started are started in a boot process according to the order of the priority, and thus the system lag caused by CPU occupation due to centralized startup of many applications or services at the same moment is avoided, the system burden is relieved and the smoothness of system running is improved.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to a boot method, a boot device and an Android smart device. Background technique [0002] With the rapid development of Android TVs using the Android system, more and more TV applications emerge as the times require. Entertainment TV has become a trend, so the TV experience is particularly important. In order to improve the experience of the product itself, many TV applications (including third-party applications) will adopt the method of starting certain services, monitoring the user's operation in the background, and providing real-time Response to improve the user's favorability. Because some services are started in Init.rc, and the way to start the application at this time is generally to listen to the system to start broadcasting ACTION_BOOT_COMPLETED. In this way, during the boot process, many applications start at a concentrated time, and the CPU usage is quite high. ...
