Embodiment three

Referring to Fig. 3, the flow chart of the data transmission method of the embodiment of the present invention three is shown, which can be with Applied to the data transmission system including first terminal and second terminal, it can specifically include following steps:

Step 301, first terminal is sent out preset program bag by the first application process in the case where connecting second terminal It send to second terminal；It include the method function for realizing data transmission in preset program bag.

In embodiments of the present invention, second terminal and the first terminal can debug the corresponding general string of bridge by Android Row bus mode or the connection of local net mode.Specifically, Android debugging bridge is divided into two kinds of bridge modes, and one kind can pass through Wired bridge mode of USB (Universal Serial Bus, universal serial bus) connection, there are also one kind can pass through local Net the wireless bridging mode of connection.For wired bridge mode, user needs to click USB (Universal in second terminal Serial Bus, universal serial bus) debugging option, so that second terminal can open USB debugging port, USB debugs port After unlatching, first terminal could be bridged by adb and second terminal.For wireless bridging mode, user then needs One terminal and second terminal are all connected to the same local area network, such as are connected to the corresponding WiFi of the same local area network (Wireless FidelitV, Wireless Fidelity), so that first terminal could be bridged by adb and second terminal.Wherein, Second terminal can be the mobile terminal for being equipped with Android (Android) system.

First terminal can create and run the first application process in the case where connecting second terminal, and then first answers Adb push (push) order can be executed with process, specified is deposited so as to push in second terminal by preset program bag It is stored under storage catalogue.In practical applications, the preset program bag namely the program bag of a jar format, the preset program Packet is compiled by an executable dex file, includes the entrance that a main function is executed as program in dex file, The method function that the main function that is to say for realizing data transmission.In addition, in a particular application, which can Think the catalogue that the process with shell permission has permission to access, such as can be/data/local/tmp catalogue, correspondingly, The adb push order specifically can be adb push server.jar/data/local/tmp, wherein server.jar is For the packet name of preset program bag.

Step 302, second terminal receives first terminal and is sent out by the first application process in the case where connecting first terminal The preset program bag sent.

In embodiments of the present invention.After first terminal sends preset program bag to second terminal, second terminal accordingly may be used To receive the preset program bag, and the preset program bag can be stored under specified storage catalogue.At this point, first terminal can be with Preset program bag is provided to second terminal as server-side, correspondingly, second terminal, which can be used as client, receives the preset journey Sequence packet.

Step 303, first terminal will be directed to the preset first port of the second application process and be mapped to first in second terminal The corresponding second port of application process.

In embodiments of the present invention, each application process would generally pass through port preset in terminal and other equipment Data interaction is carried out, therefore, when the first application process in first terminal needs to be counted by second port and second terminal When the second application process according to transmission, and in second terminal needs to carry out data transmission by first port and first terminal, the The first application process in one terminal can be got through and the second application process in second terminal by adb reverse order Between interface channel.

Specifically, the first application process can execute adb reverse tcp:port1 tcp:port2 order, by The corresponding second port of the first application process is mapped to for the preset first port of the second application process in two terminals.Wherein, Port1 is the port numbers of first port in second terminal, and port2 is the port numbers of second port in first terminal, tcp Used in (Transmission Control Protocol transmission control protocol) carries out data transmission between two ports Communication protocol.

First terminal can realize the reverse proxy of port by adb reverse order, so that first terminal and second The role of terminal changes, and second terminal will be used as client, sends one to the second port of first terminal and is used to indicate Data transmit ready process connection request, and first terminal then can be used as server-side, receive that second terminal sends into Journey connection request, so that first terminal is without standby always, and then without constantly going confirmation second terminal by way of poll Data transmission prepare it is whether ready, so as to the joint efficiency between raising process.

Step 304, second port is set listening state by first terminal.

In embodiments of the present invention, since first terminal can be used as the passive server-side for receiving data, first eventually End can set listening state for second port, be sent to monitor second terminal by second port by first port Process connection request.

Step 305, store path of the first terminal according to preset program bag in second terminal, by with target permission Process creation order, start preset program bag in second terminal, have the of target permission to create in second terminal Two application processes, the Permission Levels of target permission are greater than or equal to the Permission Levels that system strategy executes permission.

In embodiments of the present invention, by taking target permission is shell permission as an example, first terminal can be in adb shell mould The process creation order with shell permission is executed in formula, to create second application with shell permission in second terminal Process.In a particular application, which can order for app_process (application process processing).Specifically, One terminal can execute following order lines in adb shell mode:

Export CLASSPATH=/data/local/tmp/server.jar

app_process/data/local/tmp com.example.Server

Wherein ,/data/local/tmp is storage catalogue of the preset program bag in second terminal, and server.jar is pre- The packet name of program bag is set, com.example.Server is the instance objects of a class that can apply data transmission method function. So far, preset program bag start completion in second terminal, the dex file in preset program bag can be run, so as to reality The creation of existing second application process.

Since the second application process is created that in adb shell mode, the second application process has shell Permission, correspondingly, the second application process will not be strong lower than the process of shell permission by the corresponding Permission Levels of certain system strategies System is closed, such as " key acceleration ", " process cleaning " etc. improve strategy and power saving strategy of the speed of service etc., so as to To avoid the disconnecting between process.

Further, due to that preset program bag directly can be pushed to second terminal by adb push order, and can To directly initiate the preset program bag by app_process order, answered so as to create second directly in second terminal With process, therefore before the second application process and the first application process are attached, do not need to install in second terminal APK, and then a series of confirmation operation is carried out to the installation of APK without user, it goes out in this way, can be in avoid second terminal When screen state, user does not know that the bullet frame for having installation APK in second terminal needs to confirm, and then can grasp to avoid because APK is installed Connection failure caused by user confirms is obtained not in time.

Step 306, second terminal is led to when the second application process with target permission creates completion in second terminal It crosses the corresponding first port of the second application process and sends process connection request to first terminal.

In embodiments of the present invention, client of the second terminal as active transmission information, in target permission It, can be by the corresponding first port of the second application process, actively to the when two application processes create completion in second terminal One terminal sends process connection request, to inform that it is ready that the data transmission of second terminal prepares to first terminal, can start Transmit data.

Step 307, first terminal receives second eventually by second port in the case where second port is in listening state End passes through the process connection request that the corresponding first port of the second application process is sent when the second application process creates completion.

In embodiments of the present invention, since port mapping has been carried out in first terminal, first terminal can be from Two-port netwerk listens to the process connection request that second terminal is sent by first port, at this point, first terminal can know second The data transmission of terminal prepares ready.

Step 308, first terminal is according to the Internet protocol address of second terminal and the port numbers of first port, generates the The socket of two terminals, with the connection established between the first application process and the second application process.

In embodiments of the present invention, first terminal, can be with after the process connection request for receiving second terminal transmission By the socket (socket) of the port numbers of the Internet protocol address of second terminal and first port composition second terminal, and protect The socket is deposited, so far, the connection between the first application process and the second application process, which is established, to be completed, thus the first application process Data interaction can be carried out with the second application process.

When the connection between the first application process and the second application process, which is established, to be completed, first terminal and second terminal Role's it will happen again conversion, at this point, first terminal, which can be used as client, sends data or request data to second terminal, Second terminal then can be used as server-side and receive the data that first terminal is sent, or in response to the request of data of first terminal, Data are sent to first terminal.

Step 309, first terminal passes through second port and second terminal transmission objectives data.

In embodiments of the present invention, any data that target data can be generated or be stored for first terminal, correspondingly, the One terminal can by second port to second terminal send target data, and then second terminal can by first port connect Receive the target data.Certainly, target data may be any data that second terminal is generated or stored, correspondingly, first Terminal can send the acquisition request of target data to second terminal, and then second terminal is after receiving the acquisition request, Target data can be sent to the second port of first terminal by first port.

Step 310, second terminal passes through first port and first terminal transmission objectives data.

In embodiments of the present invention, when target data is any data that second terminal is generated or stored, first terminal The acquisition request of target data can be sent to second terminal, and then second terminal is after receiving the acquisition request, it can be with Target data is sent to the second port of first terminal by first port.When target data is that first terminal is generated or stored Any data when, first terminal can send target data to second terminal by second port, and then second terminal can be with By first port receive the target data.It that is to say that the first application process can be realized by second port to answer with second With between process data transmission, correspondingly, the second application process can by first port realize with the first application process it Between data transmission.

In embodiments of the present invention, first terminal can pass through the first application process in the case where connecting second terminal Preset program bag is sent to second terminal, includes the method function for realizing data transmission in preset program bag, then the It is corresponding that one terminal can will be mapped to the first application process for the preset first port of the second application process in second terminal Second port, and monitor second port, so first terminal can according to store path of the preset program bag in second terminal, By the process creation order with target permission, start preset program bag in second terminal, to create in second terminal The second application process with target permission, wherein the Permission Levels of target permission are greater than or equal to system strategy and execute permission Permission Levels, later second terminal the second application process create complete when, the second application process corresponding the can be passed through Process connection request is sent first terminal by Single port, and first terminal can be according to the Internet protocol of second terminal after receiving The port numbers of address and first port generate the socket of second terminal, to establish the first application process and the second application process Between connection, and then first terminal can pass through the corresponding second port of the first application process and second terminal transmission objectives number According to.In embodiments of the present invention, can be by the process creation order with target permission, creation has mesh in second terminal The second application process of permission is marked, the Permission Levels of target permission are greater than or equal to the Permission Levels that system strategy executes permission, That is to say that the second application process has the execution permission not less than the system strategies process such as power saving, speed-raising, therefore, second apply into Journey in the process of running, will not system strategy process identical by Permission Levels or more low rights forcibly close, so as to keep away The connection exempted between the first application process and the second application process is interrupted, and then can be improved the efficiency of data transmission.Separately Outside, first terminal can by the way of reverse proxy mapped port, so that first terminal is without standby always, and then without logical Whether the mode of overpolling constantly goes the data transmission of confirmation second terminal to prepare ready, so as to the company between raising process Connect efficiency.
