Embodiment 1

[0074] Embodiment 1: The processing flow of switching the system when playing music or video

[0075] When switching between dual operating systems, the music player is notified by sending a system broadcast to pause the music (Music) playback, and simulates the power (Power) button to put the operating system that is about to switch to the background and enter the sleep state, so that the Switch to the background operating system to pause the playback of all currently running videos (Video), so that the music player and video player will stop occupying audio and video hardware resources. At the same time, this embodiment starts a monitoring thread on the media playback server (MediaPlayerService) to monitor the system switching event. When the monitoring thread monitors that the operating system is switched from the foreground to the background, and all audio and video are stopped playing, a notification Kernel audio and video hardware resources have been released.

Embodiment 2

[0077] Embodiment 2: The processing flow of switching the system when playing the prompt tone

[0078] When the foreground system is currently playing prompt sounds (for example: screen lock, incoming call, alarm clock, etc.), the system switching cannot force the system to release the hardware resources used to play these prompt sounds from the application layer. Therefore, in this embodiment, the HAL layer is used. The audio module starts a monitoring thread to monitor system switching events. When the system switches from the foreground to the background, all audio resources are released, and the upper-layer write data operations (play audio) and read data operations (record audio) are overridden; when the system switches from the background When switching to the foreground, the upper-layer read and write data operations are reconnected.

[0079] The technical effect achieved by adopting this processing method in this embodiment is: the sound playback / recording logic of the...

Abstract

The present application discloses a method for switching operating systems with dual Android terminals, comprising: for an audio and video playback application currently running in an operating system that is about to be switched to the background in the dual Android terminals, suspending all audio and video playback applications by means of system broadcasting. The audio and video playback application; the audio and video playback application pauses the audio and video playback according to the system broadcast, and releases the audio and video hardware resources occupied by the audio and video playback application. Corresponding to the above method, the present application also discloses a dual Android terminal device. The application of the technical solution disclosed in the present application can ensure the normal operation of the upper-layer application program when the operating system is switched.

Description

technical field [0001] The present application relates to the technical field of intelligent terminals, and in particular, to a method and device for switching operating systems with dual Android terminals. Background technique [0002] Android, the common unofficial Chinese name is Android, is an open source mobile operating system based on the Linux kernel. It is continuously led and developed by the Open Handset Alliance (OHA, Open Handset Alliance) established by Google. It is mainly designed for touch screens. Mobile devices such as smartphones and tablets and other portable devices. [0003] Normally, an Android phone has only one operating system, but with the development of technology, some smart terminals with dual Android systems have appeared. However, this is actually a dual-domain smart terminal. This type of terminal can still only start one Android operating system at a time, and using two users does not start two Android systems. This switching system is no...
