Specifically, the method for cross-process communication provided by the embodiment of the present invention first acquires a first identification number of a process to be communicated. In the Android application, the embodiment of the present invention uses int pid=android.os.Process.myPid() to obtain the first identification number (process code pid) of the first application. The pid is a separate string of numbers for each process in the Android system, which is used to determine the uniqueness of the process in the system. Therefore, the pid of the process can be used as an anchor for interprocess communication. That is, other processes can connect and send data to the process through the pid.

Specifically, the method for cross-process communication provided by the embodiment of the present invention sends an access request sent by the to-be-communicated process to the target process through the communication channel to perform communication between the first application and the second application. .

It is worth mentioning that the target process in the embodiment of the present invention can access the process to be communicated in one direction through the above communication channel, and can also establish a new communication channel to the target process, so as to realize one-way access of the process to be communicated to the target process, thereby Two-way communication between the process to be communicated and the target process is implemented.

The above two-way communication method can be:

Obtaining a first identification number of the to-be-communicated process, establishing a connection between the target process and the to-be-communicated process based on the first identification number, so that the target process accesses the to-be-communicated process, thereby establishing a process between the target process and the to-be-communicated process. One-way communication. Then, the identification number of the target process is obtained, and the connection between the communication process and the target process is established based on the identification number of the target process, so that the process to be communicated is accessed to the target process, thereby establishing a one-way relationship between the communication process and the target process. Communication, thereby establishing a two-way communication between the process to be communicated and the target process.

Therefore, the communication channel between the target process and the to-be-communicated process based on the first identification number in step S102 may be the above two-way communication.

The cross-process communication method provided by the embodiment of the present invention and the communication method of the cross-application process in the prior art have high complexity of parameter configuration, resulting in poor applicability, and the data carrying capacity of the communicable communication is relatively low. First, the first identification number of the process to be communicated corresponding to the first application is obtained, and then the communication channel between the target process and the process to be communicated is established based on the first identification number, where the target process belongs to the second application. The second application and the first application are two different applications of the terminal, and finally send an access request of the process to be communicated to the target process through the communication channel, to perform communication between the first application and the second application, The utility model has the advantages of no parameter configuration, simple operation and strong applicability, and the communication channel established based on the first identification number realizes high-flow data bearing, and has good practicability.

In order to further ensure the security and the real-time performance of the communication, the method for the cross-process communication provided by the embodiment of the present invention establishes all the application processes and their correspondings after acquiring the first identification number of the process to be communicated and before establishing the communication channel. The mapping relationship between the applications, so as to determine whether the communication channel is pre-established according to the mapping relationship (that is, whether the application is started), as shown in FIG. 2, specifically implemented by the following steps:

S201: Obtain a process queue of the terminal, where the process queue is a set of all application processes currently enabled by the terminal;

S202. Extract a corresponding second identification number for each application process in the process queue.

S203. Acquire, according to each second identification number, a package name of an application corresponding to the application process to which the second identification number belongs;

S204. Establish a mapping relationship between the second identification number and the package name.

Specifically, the method for cross-process communication provided by the embodiment of the present invention further establishes a mapping relationship between an application process that has been started in the terminal and a corresponding application program, and the relationship between the application process and the application process that is being executed by the application is And can obtain the identification number of the application process.

In the embodiment of the present invention, before acquiring the process queue of the terminal, the current system information of the Android system is obtained first, that is, the current process queue of the Android may be obtained by:

ActivityManager mActivityManager=

(ActivityManager)this.getSystemService(ACTIVITY_SERVICE);

List<ActivityManager.RunningAppProcessInfo>mRunningProcess= mActivityManager.getRunningAppProcesses();

The above process queue is a collection of all application processes currently enabled by the terminal. After obtaining the process queue, the embodiment of the present invention extracts the second identification number of each application process in the process queue, and obtains the package name of the corresponding application according to the second identification number, where The package name of the application is specifically as follows:

All the acquired application processes are traversed by using a for loop, and the application package name and the second identification number (ie, process pid) of each item are stored as key value pairs in the newly created map (ie, established). The mapping relationship between the second identification number and the package name is convenient for finding the corresponding identification number according to the corresponding application package name when establishing communication later.

In addition, after the foregoing mapping relationship is established, the method for the cross-process communication provided by the embodiment of the present invention determines whether the third identification number of the target process corresponding to the second application is obtained based on the mapping relationship, and can determine After obtaining the third identification number corresponding to the second application, the communication channel between the target process and the to-be-communicated process is established based on the first identification number. Specifically, the foregoing implementation manner of establishing a communication channel between the target process and the to-be-communicated process based on the first identification number is: establishing a communication connection of the target process to be communicated by the process to be communicated based on the third identification number, thereby establishing a target process and to be communicated For the communication channel between the processes, refer to the above-mentioned two-way channel establishment manner, and details are not described herein.

Specifically, in the development of the Android system, another application that can be communicated by an application is defined in a negotiated manner. In the embodiment of the present invention, after obtaining the package name of the second application, the foregoing is based on the foregoing. Mapping a relationship, determining whether the third identification number of the target process corresponding to the second application is obtained, and if yes, establishing, according to the third identification number, the process to be communicated corresponding to the first application to access the second application a communication connection of the target process, and then establishing, according to the first identification number, a target process corresponding to the second application to access a communication connection of the process to be communicated corresponding to the first application, and then establishing a communication channel between the target process and the process to be communicated For details, refer to the above-mentioned establishment manner of the bidirectional channel, and details are not described herein. If the third identification number is not obtained, the corresponding second application is not started. Inter-process communication cannot be started when there is no startup. Therefore, if the case where the identification number cannot be found by the package name occurs, the establishment of the current interprocess communication is stopped, and the problem is returned to the first application.

The cross-process communication method provided by the embodiment of the present invention innovatively applies socket communication to the local application layer in consideration of the excellent characteristics of the socket at the network layer. Referring to FIG. 3, the process of establishing the foregoing communication channel in the embodiment of the present invention specifically includes the following steps:

S301. Configure a socket connection to the target process based on the first identification number.

S302. Establish a communication channel between the target process and the to-be-communicated process based on the socket connection.

Specifically, the method for cross-process communication provided by the embodiment of the present invention performs socket connection by:

Socket=new Socket();

Socket.connect(new InetSocketAddress("127.0.0.1",pid),5000);

It can be seen that the embodiment of the present invention preferably uses a socket to perform a communication connection, and the socket is originally a communication mode of the network layer, and the innovative method in the embodiment of the present invention achieves different local applications through different local ports. The purpose of communication. Each process in the Android system will have a corresponding process number, which is a unique identifier in the system after the application is opened, so the number can be used as the port number of a socket communication, so that each application does not need to go. Deliberately set your own unique port number, and can also guarantee that the number will not be repeated. The above method is used to achieve the purpose of establishing a socket connection, and pid is the first identification number of the process to be communicated. After the above socket is established, a communication relationship (communication channel) between the target process and the process to be communicated can be established.

The embodiment of the present invention can implement the function that the first application sends the access requirement to the second application by using the following specific manner:

OutputStream ou=socket.getOutputStream();

BufferedReader bff=New BufferedReader(new putStreamReader(socket.getInputStream()));

Ou.write("android one application".getBytes("gbk"));

Ou.flush();

Get the input and output streams with getInputStream and getOutputStream, and send an access request to the second application via ou.write.

After obtaining the first identification number of the to-be-communicated process, the method for the cross-process communication provided by the embodiment of the present invention also monitors the first identification number as the port number of the socket communication. Wherein, the above monitoring is implemented by using a serverSocket, and the first identification number of the first application is filled in the serverSocket, and the accept method is executed to perform the monitoring. The method will be built on a thread in Android and continuously loop to execute the monitoring method to achieve real-time monitoring of the communication between the first application and the second application. If there is information sent during the listening process, you can use the following code to achieve:

BufferedReaderbr=new BufferedReader(new InputStreamReader(s.getInputStream()));

String mess=br.readLine().

In the continuous listening loop, the message is judged by the above statement. If the message is not empty, it is determined that a message is received, then the message is started to be read. If the message is empty, it is determined that the message is not received, and the loop continues. .

After the second application receives the access request, the real communication can begin between the two. In the embodiment of the present invention, each time the message is sent, the package name and pid of the first application are brought, when the receiver (the second application) receives After the message, a new socket can also be created to send information to the sender (first application) to implement communication. Specifically, the method for completing the establishment of the two-way communication by using the scoket is: first, acquiring a third identification number of the target process corresponding to the second application, and the target process corresponding to the second application by the communication process of the first application is The communication connection is established through the socket. At this time, the third identification number of the target process corresponding to the second application is used as the port number of the socket communication, thereby establishing a one-way channel for the first application to access the second application. When the first application sends a message to the second application, the message carries the first identification number of the first application, and the second application acquires the first identification number of the process to be communicated of the first application. a communication connection between the target process corresponding to the second application and the to-be-communicated process of the first application is established by using a socket, and the first identification number of the process to be communicated of the first application is used as the port number of the socket communication, thereby establishing The second application accesses the one-way channel of the first application, and then the bidirectional channel between the first application and the second application is completed.

Since then, the communication mode between the two applications of the process has been established, and in the embodiment of the present invention, since it is implemented by the local default ip127.0.0.1 (local IP address) in the mobile phone, the mobile phone can be used regardless of whether the mobile phone is connected to the network.
