step 101, acquiring an application identifier of a first application installed in the vehicle-mounted system, wherein the first application is any third party application installed in the vehicle-mounted system.
Step 102, when the application identifier of the first application is included in the identifier set, the first application is added to the application set. The identification set comprises application identifications of all third-party applications supported by the vehicle-mounted system for application switching.
Step 103, when an application switching instruction is received, starting a target application in the application set.
In summary, in the application switching method provided by the embodiment of the present application, after the application identifier of the first application installed in the vehicle-mounted system is obtained, the vehicle-mounted system compares the application identifier of the first application with the application identifiers in the identifier set. And if the identification set contains the application identification of the first application, adding the first application into the application set. When the vehicle-mounted system receives the application switching instruction, a target application in the application set can be started. Because the application set can comprise the third party application, the application except the built-in application of the vehicle-mounted system is supported to be switched, and therefore the flexibility of application switching is improved.
Fig. 2 is a flowchart of another application switching method according to an embodiment of the present application. The method can be applied to an in-vehicle system. As shown in fig. 2, the method includes:
step 201, an application identifier of a first application installed in a vehicle-mounted system is obtained.
The first application is any third party application installed in the vehicle-mounted system. The third party application in the embodiment of the application refers to other applications except for the built-in application of the vehicle-mounted system. The application identifier of the first application may be a package name of the first application, or may be other information capable of uniquely identifying the first application.
Optionally, the triggering condition for the vehicle-mounted system to acquire the application identifier of the first application may be to install the first application, update the first application and/or uninstall the first application.
Step 202, acquiring an identification set.
The identification set comprises application identifications of all third-party applications supported by the vehicle-mounted system for application switching. Optionally, the identifier set may further include an interface identifier of a playing interface of the third party application, where the identifier set may include an interface identifier of a playing interface of the third party application corresponding to each application identifier, or the identifier set may include interface identifiers of playing interfaces of third party applications corresponding to one or more application identifiers. The vehicle-mounted system acquires the identification set from the corresponding service end of the vehicle-mounted system in a wired transmission or wireless transmission mode. Alternatively, the server may be a server, or a server cluster formed by a plurality of servers, or a cloud computing service center, etc., which is not limited in the embodiment of the present application.
The server is responsible for maintaining the set of identifications. Optionally, the server side periodically acquires application identifiers of third-party applications supported by the vehicle-mounted system in the application market for application switching, and compares the application identifiers with the application identifiers in the identifier set stored in the server side. When the application identifier of the third party application supporting the application switching in the vehicle-mounted system in the application market exists in the application identifier which is not included in the identifier set, the server adds the application identifier into the identifier set. When other application identifiers except the application identifiers of the third party applications supported by the vehicle-mounted system for application switching in the application market exist in the identifier set, the server side deletes the other application identifiers from the identifier set.
When the server adds the application identifier of the third party application to the identifier set, if the interface identifier of the playing interface of the third party application is valid, the server may also add the interface identifier of the playing interface of the third party application to the identifier set. For example, the interface identifier of the playback interface of the third party application may be an activity name of the playback interface of the third party application.
Alternatively, after the on-board system is powered on, the on-board system may acquire the identifier set by means of wireless transmission whenever networking is performed, or the on-board system may periodically acquire the identifier set by means of wireless transmission. Or the vehicle-mounted system and the server end are connected in a wired way, and then the identification set is obtained in a wired transmission mode.

Optionally, the application set includes built-in applications of the vehicle-mounted system and third-party applications, and the applications in the application set have an arrangement order. The arrangement order may be an order set manually, or may be a time order of application installation, for example. Alternatively, applications in the application set may be manually ordered, added, and deleted.
Optionally, the triggering condition for the vehicle-mounted system to acquire the application set may be to install the first application, update the first application and/or uninstall the first application.
Optionally, after the first application is added to the application set, when the vehicle-mounted system receives an update instruction for the first application, an application identifier of the first application in the application set and an interface identifier of a playing interface of the first application are updated. Because the package name of the application and/or the activity name of the playing interface may change when the application is updated, after the application is updated, the application identifier of the application and the interface identifier of the playing interface in the application set are updated, so that the validity of the application identifier of the application and the interface identifier of the playing interface in the application set can be ensured.
Optionally, after the first application is added to the application set, when the vehicle-mounted system receives a deletion instruction for the first application, the first application in the application set is deleted.

in step 2041, when the in-vehicle system receives an application switching instruction during the playing of the multimedia stream, a second application providing the multimedia stream is acquired. The second application is an application currently playing the multimedia stream.
Alternatively, when a pressing operation for a target key of the in-vehicle system is detected, it is determined that an application switching instruction is received. The target key may be a MODE key on a vehicle steering wheel, for example. Alternatively, when a voice including a keyword for application switching is detected, it is determined that an application switching instruction is received, the keyword may be "switch next multimedia application" or "switch multimedia", or the like.
In step 2042, when the second application is included in the application set, a next application of the second application in the application set is taken as a target application, and the target application is started.
Optionally, when the second application is the last application in the application set, its next application (i.e., the target application) is the first application in the application set.
In step 2043, when the second application is not included in the application set, the first application in the application set is taken as the target application, and the target application is started.
Optionally, when the application set includes the target application identifier of the target application and the target interface identifier of the playing interface of the target application, starting the playing interface of the target application according to the target application identifier and the target interface identifier. Or when the application set only comprises the target application identifier of the target application, starting the target application according to the target application identifier.
The vehicle-mounted system in the embodiment of the application mainly refers to a system based on android system (android), and any vehicle-mounted system capable of implementing the method of the application is included in the protection scope of the application, and the application is not described herein.
It should be noted that, the sequence of the steps of the application switching method provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be increased or decreased according to the situation, for example, before step 201, the vehicle-mounted system may first obtain the identifier set, that is, the vehicle-mounted system first executes step 202 and then executes step 201. Any method that can be easily conceived by those skilled in the art within the technical scope of the present disclosure should be covered in the protection scope of the present application, and thus will not be repeated.
In summary, according to the application switching method provided by the embodiment of the present application, the vehicle-mounted system obtains the application identifier and the identifier set of the first application installed in the vehicle-mounted system, and compares the application identifier of the first application with the identifier set.

The acceleration sensor 711 can detect the magnitudes of accelerations on three coordinate axes of the coordinate system established with the in-vehicle system 700. For example, the acceleration sensor 711 may be used to detect the components of the gravitational acceleration in three coordinate axes. The processor 701 may control the touch display screen 705 to display a user interface in a landscape view or a portrait view according to the gravitational acceleration signal acquired by the acceleration sensor 711. The acceleration sensor 711 may also be used for the acquisition of motion data of a game or a user.
The gyro sensor 712 may detect a body direction and a rotation angle of the vehicle-mounted system 700, and the gyro sensor 712 may collect a 3D motion of the user on the vehicle-mounted system 700 in cooperation with the acceleration sensor 711. The processor 701 may implement the following functions based on the data collected by the gyro sensor 712: motion sensing (e.g., changing UI according to a tilting operation by a user), image stabilization at shooting, game control, and inertial navigation.
The pressure sensor 713 may be disposed at a side frame of the in-vehicle system 700 and/or at an underlying layer of the touch display screen 705. When the pressure sensor 713 is disposed at a side frame of the in-vehicle system 700, a grip signal of the user to the in-vehicle system 700 may be detected, and the processor 701 performs left-right hand recognition or quick operation according to the grip signal collected by the pressure sensor 713. When the pressure sensor 713 is disposed at the lower layer of the touch display screen 705, the processor 701 controls the operability control on the UI interface according to the pressure operation of the user on the touch display screen 705. The operability controls include at least one of a button control, a scroll bar control, an icon control, and a menu control.
The fingerprint sensor 714 is used to collect a fingerprint of the user, and the processor 701 identifies the identity of the user according to the fingerprint collected by the fingerprint sensor 714, or the fingerprint sensor 714 identifies the identity of the user according to the collected fingerprint. Upon recognizing that the user's identity is a trusted identity, the processor 701 authorizes the user to perform relevant sensitive operations including unlocking the screen, viewing encrypted information, downloading software, paying for and changing settings, etc. The fingerprint sensor 714 may be provided on the front, back, or side of the in-vehicle system 700. When a physical key or vendor Logo is provided on the in-vehicle system 700, the fingerprint sensor 714 may be integrated with the physical key or vendor Logo.
The optical sensor 715 is used to collect the ambient light intensity. In one embodiment, the processor 701 may control the display brightness of the touch display 705 based on the ambient light intensity collected by the optical sensor 715. Specifically, when the intensity of the ambient light is high, the display brightness of the touch display screen 705 is turned up; when the ambient light intensity is low, the display brightness of the touch display screen 705 is turned down. In another embodiment, the processor 701 may also dynamically adjust the shooting parameters of the camera assembly 706 based on the ambient light intensity collected by the optical sensor 715.
The proximity sensor 716, also referred to as a distance sensor, is typically disposed on a front panel of the in-vehicle system 700. The proximity sensor 716 is used to capture the distance between the user and the front of the in-vehicle system 700. In one embodiment, when the proximity sensor 716 detects that the distance between the user and the front face of the in-vehicle system 700 gradually decreases, the processor 701 controls the touch display screen 705 to switch from the bright screen state to the off screen state; when the proximity sensor 716 detects that the distance between the user and the front face of the in-vehicle system 700 gradually increases, the processor 701 controls the touch display screen 705 to switch from the off-screen state to the on-screen state.
Those skilled in the art will appreciate that the configuration shown in fig. 7 is not limiting of the in-vehicle system 700 and may include more or fewer components than shown, or may combine certain components, or may employ a different arrangement of components.
