The mapping relationship between the system position and the partition is pre-stored in the application program cross-system communication device, and the mapping relationship between the system position and the partition is shown in the following table 1:
TABLE 1
| System location | Partition(s) |
| First hard disk | Main partition |
| Second hard disk | First expansion partition |
| Third hard disk | Second expansion partition |
| …… | …… |
The system positions are in one-to-one correspondence with the partitions; if the system position is the first hard disk, the partition is a main partition; if the system position is the second hard disk, the partition is a first expansion partition; if the system position is the third hard disk, the partition is a second expansion partition.
The mapping relationship between the partition and the control system is shown in the following table 2:
TABLE 2
| Partition(s) | Control system |

205. When it is detected that the application program a needs to send target communication data to the application program B in another android system, the application program cross-system communication device sends the target communication data from the application program a to the application program B through a socket communication network.
As can be seen, port usage conflicts are likely to occur compared to establishing a large number of wireless socket communication links, resulting in lower communication efficiency for application program cross-system communication; meanwhile, a large number of wireless socket communication links are established, so that the communication load of cross-system communication of application programs is increased, and in the embodiment of the application, a socket communication network with a star topology structure is formed based on a plurality of android systems and a plurality of system positions, and a plurality of application programs in each of the plurality of android systems are bound with the cross-system communication service of each of the android systems, so that target communication data can be sent from one application program in one of the android systems to one application program in the other android system through the socket communication network. Because communication data transmitted through a socket communication network cannot collide, communication efficiency of cross-system communication of application programs is facilitated; because any two application programs in different android systems can transmit communication data through a socket communication network, a large number of wireless socket communication links are prevented from being established, and the communication load of cross-system communication of the application programs is reduced.
In some possible embodiments, the application cross-system communication device sending the target communication data from application a to application B through the socket communication network includes:
the method comprises the steps that an application program cross-system communication device obtains a first ID of an application program B and a second ID of an android system where the application program B is located;
if the android system where the application program B is located is determined to be the central control system according to the second ID, the application program cross-system communication device sends target communication data from a socket client of the android system where the application program A is located to a socket server;
and the application program cross-system communication device sends the target communication data to the application program corresponding to the first ID through the socket server.
The application cross-system communication device may determine a target control system corresponding to the target system ID according to a mapping relationship between the pre-stored system ID and the control system.

TABLE 3 Table 3
| System ID | Control system |
| First System ID | Central control system |
| Second System ID | First non-central control system |
| Third System ID | Second non-central control system |
| …… | …… |
The system IDs are in one-to-one correspondence with the control systems; if the system ID is the first system ID, the control system is a central control system; if the system ID is the second system ID, the control system is a first non-central control system; if the system ID is the third system ID, the control system is the second non-central control system.
It can be seen that, in this example, if a certain application program a in a non-control system sends communication data to a certain application program B in a central control system, the communication data is sent from a socket client of the android system where the application program a is located to a socket server of the central control system, and the communication data is sent to the corresponding application program B through the socket server of the central control system. Because communication data transmitted through a socket communication network cannot collide, communication efficiency of cross-system communication of application programs is facilitated; because any two application programs in different android systems can transmit communication data through a socket communication network, a large number of wireless socket communication links are prevented from being established, and the communication load of cross-system communication of the application programs is reduced.
In some possible embodiments, the application cross-system communication device sending the target communication data from application a to application B through the socket communication network includes:
the application program cross-system communication device acquires a third ID of the application program B and a fourth ID of an android system where the application program B is located;

The application program cross-system communication device sends the target communication data to a socket client of the android system corresponding to the fourth ID through a socket server;
and the application program cross-system communication device sends the target communication data to the application program corresponding to the third ID through the socket client of the android system corresponding to the fourth ID.
In this example, if an application program a in one non-central control system sends communication data to an application program B in another non-central control system, the communication data is sent from a socket client of the android system where the application program a is located to a socket server of the central control system, the communication data is sent to the socket client of the android system where the application program B is located through the socket server, and the communication data is sent to the corresponding application program B through the socket client of the android system where the application program B is located. Because communication data transmitted through a socket communication network cannot collide, communication efficiency of cross-system communication of application programs is facilitated; because any two application programs in different android systems can transmit communication data through a socket communication network, a large number of wireless socket communication links are prevented from being established, and the communication load of cross-system communication of the application programs is reduced.
