specific Embodiment

[0052] An efficient Android terminal screen sharing method is provided in this specific embodiment, which can be implemented according to the following steps:

[0053] Step 1: Configure screen sharing parameters, including server expectations, screen capture rate, number of image caches, and shared screen area;

[0054] Step 2: Turn on Wi-Fi Direct on both devices at the same time, obtain the peer list and select a peer connection. When connecting, the one with the larger expected value of the two devices is the Group Owner, and the other is the Group Client. The Group Client depends on the service Send a connection request through the terminal socket information, and establish a data channel with the Group Owner;

[0055] Step 3: Apply to the user for screen acquisition permission. After obtaining user authorization, call the Android system interface to capture screen content data at regular intervals, remove the line spacing existing in the buffered data, and obtain full-scr...

Abstract

The invention discloses an Android terminal screen sharing method, and relates to the technical field of wireless data sharing at close range. The method establishes a data transmission channel between Android terminals through connection established by Wi-Fi Direct and achieves real-time transmission of data by means of a wireless direct connection technology; in the first time, only the screen information of a user-specified area is sent to a server; from the second time, only the area image which has changes for once in a shared area and starting point coordinates thereof are sent to the server at a time, so that the amount of shared transmission is reduced, transmission speed of shared data is accelerated, and real time performance of shared information is ensured; meanwhile, only theuser-specified area is shared, so that the problem of privacy leakage when an Android terminal screen is shared is solved, and security of user personal information is ensured.

Description

technical field [0001] The invention relates to the technical field of short-range data wireless sharing, in particular to a method for Android terminal screen sharing. Background technique [0002] With the gradual maturity of Android terminal products, wireless data transmission technology is used to transmit data between Android terminals, realize interface sharing of pictures, games, videos, etc., and the demand for completing demonstration teaching, screen viewing and other related functions is gradually increasing. [0003] At present, sharing between short-distance Android terminal screens is to capture the entire mobile phone screen and send it to the requesting party. In addition to the sharing information required by the requesting party, the entire mobile phone screen also contains information on the user's mobile phone. Other information displayed and all operations on the interface, so this method of capturing a full-screen image for sharing has the following pr...
