1. A screen projection method applied to a sink device, comprising:
receiving an identification detection request from a source device within a preset range of the sink device;
obtaining real-time proximity information for the source device based on the identification detection request;
comparing the real-time proximity information with learned proximity information for the source device to obtain a comparison result; and
in response to determining the comparison result indicates that the real-time proximity information matches the learned proximity information, receiving a screen projection request from the source device to perform screen projection;
wherein
the identification detection request includes a first signal strength value of the source device, and the real-time proximity information includes a first proximity signal strength value of the source device relative to the sink device and a first Media Access Control (MAC) address of the source device; and
wherein the obtaining of the real-time proximity information comprises:
obtaining a MAC address encapsulated by the source device into the identification detection request, as the first MAC address of the source device;
obtaining a plurality of history first signal strength values from a plurality of history identification detection requests that are received, and calculating a first average value of the plurality of history first signal strength values;
setting a signal strength value range based on the first average value; and
obtaining a second average value of ones of the plurality of history first signal strength values within the signal strength value range, as the first proximity signal strength value.
