Detailed Description
The technical solutions of the exemplary embodiments provided in the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The various embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1 shows an information interaction method based on two-dimensional codes according to an embodiment of the present invention. The information interaction method may include steps S11-S16.
S11: the first terminal calls the contact information and generates a two-dimensional code corresponding to the contact information.
The first terminal may call contact information in a vCard (Personal Data exchange) format, where the contact information includes, but is not limited to, information such as a mobile phone number, an address, and an avatar of a contact in the address list. The vCard format field records the contact information through the identifier, that is, the identifiers with different values have a mapping relation with different contact information. Since the value of the identifier of the vCard format field is limited, in order to add more contact information, in this embodiment, an enumeration type may be used to record a mapping relationship between the identifier of the vCard format field and the contact information, that is, in this embodiment, all possible values of the identifier of the vCard format field are listed one by one, and a mapping relationship is established between the identifier of the vCard format field and the contact information.
The first terminal can select partial information of a certain designated contact according to a user instruction and generate the two-dimensional code. Specifically, after receiving the user instruction, the system of the first terminal may acquire a specified field in the vCard format field through a Content Provider component. Of course, other embodiments of the present invention may also default to retrieve all information of a certain designated contact and generate a corresponding two-dimensional code when a user instruction is not received.
In this embodiment, a ZXing (open source project) source code may be used to encode the vCard format field, and after encoding, a Bit Matrix object is returned, and finally the Bit Matrix object is used to draw the two-dimensional code. The drawn two-dimensional code comprises an image finding graph, a positioning graph, data coding content and an error correction information code. The image finding graph and the positioning graph are represented as three 'return' font areas of the two-dimensional code and used for determining the position of the two-dimensional code and providing coordinate reference. The coded content of the data, namely the vCard format field, is converted into a bar code according to a certain preset coding algorithm. The error correction information code is used to specify the fault tolerance rate of the two-dimensional code to ensure the fault tolerance of the data, and the error correction information code may be an RS code (Reed Solomon code). The higher the fault tolerance of the two-dimensional code is, the more error correction information codes are contained in the two-dimensional code, and the repairability of the two-dimensional code is higher.
Further, in this embodiment, an add Logo (labeling identifier) method may be adopted to add a contact photo in the middle of the two-dimensional code. Specifically, the system of the first terminal synthesizes and draws two pictures, namely the two-dimensional code and the contact head portrait, according to a certain proportion by adopting a Canvas (overlay) algorithm. In the process of composite rendering, data in the middle of the original two-dimensional code (the two-dimensional code before composite rendering) is covered and lost, so that the fault tolerance of the original two-dimensional code needs to be high.
S12: the first terminal screens out an application program capable of transmitting the bitmap file, and sends the two-dimensional code to the second terminal through the application program.
The two-dimensional code is essentially a bitmap file (bitmap), so that the way of sharing one two-dimensional code is the same as the way of sharing one picture. Based on this, referring to fig. 2, first, the system of the first terminal sets the action of the Intent component to SEND, i.e., Intent. Then, the information of all the applications having "image/jpeg" or "image/" installed in the first terminal can be acquired by the get Package Info function of the Package Manager component. If the Intent component specifies that the two-dimensional code needs to be shared by using a specific application program, the first terminal can acquire a List (List) of Result Info (Result information) through the Package Manager component, and determine the target application program by comparing the Package Name of the Result Info with the Package Name of the target application program. And finally, the system takes the component of the target application program as the component of the Intent component, and calls a startActivity function to send the two-dimensional code out, so that the two-dimensional code is shared by the target application program.
S13: and the second terminal receives the two-dimension code and stores the two-dimension code in a system picture library.
After the second terminal successfully acquires the two-dimensional code transmitted by the first terminal, the system picture library of the second terminal changes, and a new two-dimensional code is added into the system picture library.
S14: and the second terminal monitors whether the system picture library has a newly added picture or not.
Taking the Android system as an example, the system of the second terminal may use a Content Observer component to monitor data changes in the system picture library. When data in the system picture library changes, the Content Observer component can return data before and after the change through an onChange () function (to-be-changed function), so as to acquire a newly added picture.
In order to increase the monitoring duration of the system picture library, i.e. to keep the monitoring status as macro as possible, the present embodiment may perform the monitoring in one of three ways as shown in fig. 3.
Firstly, the priority of the background process of the monitoring system picture library is improved, so that the background process is changed into a Service process (Intent Service), and whether a newly added picture exists in the system picture library is monitored through the Service process. Specifically, a priority value of the background process is set in an Android Manifest (list), for example, the highest value is 1000. Then, calling the onStartCommand function returns a START _ stimkt (continuous) command. Based on the above, the service process may be finished running when the system resources are in shortage, but when the system resources are recovered, the service process is restarted, so as to continuously monitor whether the system picture library has new pictures.
Secondly, the running priority of the background process of the monitoring system picture library in the foreground is improved, and then whether the system picture library has newly added pictures or not is monitored through the background process. Specifically, the system of the second terminal sets the receiverjboot _ COMPLETED component to permission to separate the activity process and the service process. The service process receives a power-on signal through a BR (Broadcast Receiver) and starts the service process. The service process then calls the start Foreground function. after the activity Process is started, the activity Process is bound with the service Process, and the activity Process and the service Process are communicated in an IPC (Inter-Process Communication) mode, so that whether a notification item of a newly added picture exists or not can be displayed in a menu notification bar of the second terminal. and when the activity process exits, the activity process and the service process are unbound.
And thirdly, alternately monitoring whether the system picture library has new pictures or not by using the service process and the daemon process. The service process and the daemon process keep a parent-child relationship, and if the child process is finished, the parent process recreates the child process; if the parent process is finished, the child process restarts the parent process using an AM (Activity Manager) command. Namely, the service process monitors the running state of the daemon process, and if the daemon process is finished, the service process calls the daemon process again; and the daemon monitors the running state of the service process, and if the service process is finished, the daemon calls the service process again.
Of course, other embodiments of the present invention may determine whether there is a new picture by monitoring the identifier of the picture in the picture library of the system. Specifically, the monitoring service is attached to some specific software, and when the software is opened and run by a user, the background service process can perform traversal search on identifiers of pictures in the system picture library so as to screen out newly added pictures. Wherein, the identifier can use bit type, if the picture is monitored, its identifier is modified to 1, otherwise null. In this way, when the system picture library has a large number of pictures, even if the system picture library is traversed once, the loss in time and resources can be reduced.
If the system picture library is monitored to have new pictures, executing steps S15-S16. If no new picture in the system picture library is detected, the step S14 is continued until a new picture in the system picture library is detected, and the steps S15 to S16 are not executed.
S15: and the second terminal detects whether the newly added picture contains the two-dimensional code.
As shown in fig. 4, in the present embodiment, the size of the focus frame of the two-dimensional code scan may be modified by a getframemergerclect () function (rectangular frame function) in the ZXing (open source entry) source code, that is, the size of the focus frame is not limited to 5/8 of the size of the picture (screen), and then the conversion from the screen resolution of the second terminal to the camera resolution is completed by the getframemergerclectnpreview () function (rectangular frame preview function), so that the entire size of the picture can be displayed in the focus frame. Then, scanning the picture through the focusing frame, judging whether the picture has three hui-shaped identifiers, if so, judging that the newly added picture contains the two-dimensional code, and executing the step S16; if not, it is determined that the newly added picture does not include the two-dimensional code, and the subsequent scanning process is not performed on the picture, so that the process may continue to execute step S14. In the embodiment, whether the picture contains three 'hui' font identifiers or not is detected by scanning, and the picture does not need to be scanned in a full disc and all contents of the two-dimensional code are analyzed.
S16: and the second terminal scans the two-dimensional code to acquire corresponding contact information.
The embodiment can call decode () function (decoding function) of QRCode Reader (two-dimensional code reading) component in the ZXing source code to automatically scan the two-dimensional code.
Based on the above, in the embodiment, the current universal two-dimensional code is used for sharing and interacting the contact information, so that the defect that the user needs to manually add the information in the traditional text or accessory sharing mode is overcome, and meanwhile, certain data confidentiality is achieved. In addition, compared with the prior art that only two-dimensional codes can be generated for the contact information in the address list, the embodiment can allow the two-dimensional codes to carry more contact information.
In addition, the two-dimensional code of the contact information is sent through the application program capable of transmitting the bitmap file, the embodiment can share the contact information in multiple channels, for example, a user can transmit the contact information through the application programs such as multimedia messages, WeChat and mails, so that the opposite side does not need to scan the two-dimensional code in the same plane or in a close range, the user operation can be reduced, and the limitation of geographical positions is avoided.
And moreover, the background service process automatically detects whether the newly added picture contains the two-dimensional code and identifies the information in the newly added picture, so that the traditional two-dimensional code scanning mode of scanning the picture library of the system, namely 'opening a scanner, opening the picture library of the system, selecting the picture in the picture library of the system and scanning the two-dimensional code' is changed, and the user operation can be greatly simplified.
Please refer to fig. 5, which illustrates an information interaction method based on two-dimensional codes according to another embodiment of the present invention. The information interaction method may include steps S51-S56.
S51: the first terminal calls the contact information and generates a two-dimensional code corresponding to the contact information.
S52: the first terminal screens out an application program capable of transmitting the bitmap file, and sends the two-dimensional code to the second terminal through the application program.
S53: and the second terminal receives the two-dimension code and stores the two-dimension code in a system picture library.
S54: the second terminal device monitors whether the system picture library has a plurality of newly added pictures within the preset time.
When it is detected that there are a plurality of new pictures in the system picture library within the predetermined time, the embodiment executes steps S55 and S56. When it is detected that there is only one newly added picture in the system picture library within the predetermined time, the present embodiment directly performs step S56.
S55: and the second terminal acquires the pictures containing the two-dimensional codes in the newly added pictures and displays the pictures to the user, and scans the two-dimensional codes according to the user instruction.
S56: and the second terminal scans the two-dimensional code to acquire corresponding contact information.
Based on the foregoing description of the embodiment, but different from the foregoing description, the system of the second terminal in this embodiment performs a delay operation for a predetermined time (e.g. 2 seconds) to distinguish the purpose of the user operation. When only one newly added picture is imported in the preset time period, the picture is intentionally added by the user, scanning is needed with a high probability, the system detects whether the newly added picture contains the two-dimensional code after the time delay is finished, and if the newly added picture contains the two-dimensional code, the newly added picture is directly scanned, corresponding contact information is obtained and stored. If a plurality of newly added pictures are imported in the preset period of time, the purpose that the user needs to automatically scan the two-dimensional code is not strong, and therefore, the newly added pictures only need to be detected whether to contain the two-dimensional code or not after the time delay is finished.
When a plurality of newly added pictures are imported within the predetermined period of time, the embodiment may add URIs (Uniform Resource identifiers) of the plurality of newly added pictures into the queue to be processed, without caching the newly added pictures. Only when the user operates the pictures in the queue to be processed, the embodiment caches the newly added pictures according to the URI, displays the pictures containing the two-dimensional code to the user, and gives the user a choice whether to scan or not.
For a terminal with extremely limited CPU and Memory resources, a large amount of system resources are easily occupied in the process of loading and processing pictures, which causes system congestion and affects the performance of the whole system, and an Out of Memory (Out of Memory) phenomenon may occur in a serious case. Based on this, when it is monitored that there are multiple newly added pictures in the system picture library within the predetermined time, this embodiment may add the multiple newly added pictures to the blocking queue in sequence, establish a thread pool, and detect whether the multiple newly added pictures in the blocking queue include the two-dimensional code by using multiple working threads established by the thread pool.
Referring to fig. 6, the maximum number of openable work threads of the task is set to be N by using the thread pool, and the thread pool itself has no work thread when being created. And the thread pool manager sequentially adds a plurality of newly-added pictures acquired within preset time into a blocking queue, and the blocking queue can ensure that the processing process is orderly carried out. And the blocking queue can block the current working thread, if the blocking queue is empty, the current working thread can be blocked until a new picture is added in the blocking queue, and then the blocked working thread can be awakened. And the awakened working thread judges whether the newly added picture contains the two-dimensional code or not, and adds the judgment result into a result queue. And the thread pool manager acquires the pictures containing the two-dimensional codes from the plurality of newly added pictures from the result queue. By means of blocking the queue and the thread pool, the embodiment can effectively manage and dispatch the working thread to identify whether a plurality of newly-added pictures contain the two-dimensional code, and excessive system resource consumption is avoided.
