For example, a usb disk is inserted into an interface of the electronic device, or an SD card may be inserted into the mobile terminal device.
In the prior art, one of the dual systems of the electronic device operates in the foreground of the electronic device, the other of the dual systems operates in the background of the electronic device, and when the external device is connected to the electronic device, the external device is mounted on the system operating in the foreground, so that the system operating in the foreground can access the external device.

In one example, a driver service is configured in the kernel.
In an example, fig. 3 is an architecture diagram of a first system provided in the present application, and as shown in fig. 3, a first vold layer includes a first network link management service, a first command monitoring service, a first volume management service, and a first network link processing service; the first command monitoring service and the first volume management service can transmit messages and instructions, and the first volume management service and the first network link processing service can transmit messages and instructions. The first service layer of the first system comprises a first storage management service, the first mounting service and a first NDC service; the first storage management service and the first mounting service can transmit messages and instructions, and the first mounting service and the first NDC service can transmit messages and instructions. The first mount service can transmit messages and instructions with the first command monitoring service of the first vold layer through the first NDC service, that is, the first mount service can transmit messages and instructions with the first vold layer through the first NDC service; the first NDC service can transmit messages and instructions with the first command monitoring service through the first socket; the first network link processing service of the first vold layer can transfer messages and instructions with the kernel, that is, the first vold layer can transfer messages and instructions with the kernel. The driver service of the kernel and the first network link processing service can transfer messages and instructions, that is, the kernel and the first vold layer can transfer messages and instructions.
In an example, fig. 4 is an architecture diagram of a second system provided in the present application, and as shown in fig. 4, the second vold layer includes a second network link management service, a second command monitoring service, a second volume management service, and a second network link processing service; the second command monitoring service and the second volume management service can transmit messages and instructions, and the second volume management service and the second network link processing service can transmit messages and instructions. The second service layer of the second system comprises a second storage management service, the second mounting service and a second NDC service; the second storage management service and the second mounting service can transmit messages and instructions, and the second mounting service and the second NDC service can transmit messages and instructions.

The driver service of the kernel and the second network link processing service can transfer messages and instructions, that is, the kernel and the second vold layer can transfer messages and instructions.
The method comprises the steps that an external interface is arranged on the electronic equipment, and when a user inserts the external equipment into the external interface of the electronic equipment, the inner core can detect that the external equipment is inserted into the external interface of the electronic equipment; thus, the kernel may generate an insertion message that characterizes the insertion of the external device onto the external interface of the electronic device.
In one example, an electronic device is configured with a first system and a second system, the first system running in a foreground of the electronic device, the second system running in a background of the electronic device; a user inserts an external device into an external interface of the electronic device; the kernel of the electronic device can detect that the external device is inserted into the external interface of the electronic device.
S102, the kernel sends the insert message to the first vold layer and the second vold layer respectively.
In this step, the driver service of the kernel sends the insertion message generated by the kernel to the first vold layer of the first system and the second vold layer of the second system, respectively.
In one example, the driver service of the kernel sends an insert message to a first network link processing service of a first vold layer; meanwhile, the drive service of the kernel inserts the message and sends the message to the second network link processing service of the second vold layer.
S103, the first vold layer sends the insert message to the first mounting service through the first socket, and the second vold layer sends the insert message to the second mounting service through the second socket.
In this step, since the first socket may communicate the first vold layer with the first mount service of the first service layer, the first vold layer of the first system may send the insert message to the first mount service of the first service layer through the first socket.
In one example, a first mount service may transmit messages and instructions with a first command monitoring service of a first vold layer through a first NDC service, the first NDC service may transmit messages and instructions with the first command monitoring service through a first socket, the first command monitoring service may transmit messages and instructions with a first volume management service, and the first volume management service may transmit messages and instructions with a first network link processing service, so that the first network link processing service of the first vold layer of the first system sends an insert message to the first command monitoring service of the first vold layer through the first volume management service; then, the first command listening service sends the insertion message to a first NDC service of the first service layer through a first socket; then, the first NDC service transmits the insert message to a first mount service of the first service layer.
Since the second socket can communicate the second vold layer with the second mount service of the second service layer, the second vold layer of the second system can send the insertion message to the second mount service of the second service layer through the second socket.
In one example, the second mount service may transmit the message and the instruction with the second command monitoring service of the second vold layer through the second NDC service, the second NDC service may transmit the message and the instruction with the second command monitoring service through the second socket, the second command monitoring service may transmit the message and the instruction with the second volume management service, and the second volume management service may transmit the message and the instruction with the second network link processing service, so that the second network link processing service of the second vold layer of the second system sends the insert message to the second command monitoring service of the second vold layer through the second volume management service; then, the second command listening service sends the insert message to a second NDC service of the second service layer through a second socket; the second NDC service then sends an insert message to a second mount service of the second service layer.

and S505, the first application service layer acquires a formatting instruction triggered by a user.
In this step, a first application service layer is also included in the first system; the first application service layer can directly transmit information and instructions with the kernel, or the first application service layer can transmit information and instructions with the kernel through the first mount service and the first vold layer.

Then, the second system can unload the external device from the second system; in one example, the second mounting service of the second system unloads the external device from the second system after receiving the message returned by the second mounting service.
In one example, when the second monitoring service determines that the second system mounts the external device, the second monitoring service sends a first response message to the first monitoring service of the first system, where the first response message indicates that the second system mounts the external device; then, the first listening service of the first system sends the first response message to the first application service layer of the first system. Therefore, the first application service layer of the first system can generate first prompt information according to the first response message, wherein the first prompt information is used for indicating that the second system mounts the external device; then, the first application service layer of the first system displays first prompt information to a user, and the user can know that the second system mounts the external equipment; therefore, the user needs to manually trigger the second system to firstly uninstall the external device, and then the first system can perform formatting processing on the external device, at this time, the user triggers the second application service layer of the second system to input a second uninstalling instruction to the second application service layer. Further, a second application service layer of the second system can acquire a second unloading instruction; then, the second application service layer generates a second unloading event according to the second unloading instruction, and meanwhile, the second application service layer calls a second mounting service of a second system; furthermore, a second mount service of the second system can acquire a second uninstall event; then, the second mount service of the second system can uninstall the external device from the second system.

In one example, after the external device is uninstalled from the second system by the second mount service of the second system, the electronic device may automatically trigger completion of the formatting process of the external device; at this time, the second mounting service of the second system unloads the external device from the second system, and then the second monitoring service of the second system can monitor that the external device is unloaded from the second system; then, the second monitoring service of the second system sends a second response message to the first monitoring service of the first system, wherein the second response message indicates that the external equipment is unloaded from the second system; then, the first monitoring service of the first system sends the second response message to the first application service layer of the first system; then, a first application service layer of the first system can call a first mounting service of the first system; and then the first mounting service of the first system can format the external device mounted on the first system according to the previous formatting event.
In one example, after step S508, the following steps may be further included:
s509, the first mount service sends a third response message to the first application service layer, where the third response message is used to indicate that the external device completes formatting.
In this step, after the first mount service of the first system formats the external device, the first mount service sends a third response message to the first application service layer, where the third response message indicates that the external device completes formatting. Furthermore, the first application service layer can know that the first system completes the formatting process of the external device.
And S510, generating and displaying second prompt information by the first application service layer, wherein the second prompt information represents that the external equipment completes formatting.
In this step, the first application service layer generates second prompt information and displays the second prompt information to the user, so that the user knows that the first system has formatted the external device.
In one example, after step S506, the following steps may also be performed:
and S511, when the second monitoring service determines that the second system does not mount the external device, the second monitoring service returns a fourth response message to the first application service layer through the first monitoring service, wherein the fourth response message is used for indicating that the second system does not mount the external device.
In this step, after step S506, if the second monitoring service determines that the second system does not mount the external device, the first system may directly perform formatting processing on the external device mounted by the first system. At this time, if the second monitoring service determines that the second system does not mount the external device, the second monitoring service sends a fourth response message to the first monitoring service of the first system, and the fourth response message indicates that the second system does not mount the external device; and then, the first monitoring service of the first system returns the fourth response message to the first application service layer of the first system, so that the first application service layer knows that the second system does not mount the external device.
S512, the first application service layer calls the first mounting service.
In this step, after the first application service layer learns that the second system is not equipped with the external device, the first application service layer may directly invoke the first mounting service of the first system.
And S513, the first mounting service carries out formatting processing on the external equipment according to the formatting event.
In this step, the first mount service of the first system may know that the second system does not mount the external device, and further, the first mount service of the first system may format the external device according to the formatting event in step S506.
In this embodiment, on the basis of the above embodiment, when the external device needs to be formatted, the first application service layer of the first system sends the formatting event to the second monitoring service of the second system through the first monitoring service of the first system; furthermore, when the second monitoring service of the second system determines that the second system mounts the external device, the second system can unload the external device, so that the first mounting service of the first system formats the external device; when the second monitoring service of the second system determines that the second system does not mount the external device, the first mounting service of the first system can directly format the external device. Therefore, when the external device is mounted on the first system and the second system, the formatting process of the external device can be completed in one system.
