1. Research and evaluation

1.1 Review

This assignment is tested on the IOS side, web side and WeChat applet, and at the same time with Android classmates to test the complete software, you can get some Android side bugs and Android and IOS side chat bugs

1. Use process

• web

• 

• 

 

• IOS edge

•                

 

• Applet

•             

2. Functional bug

(1) Unread and read chaos

When user A uses the web terminal and user B uses the IOS terminal to chat, when user A has already replied to the message, user B's interface displays the sent message as unread. Only when using the mobile phone to chat at the same time, the unread message will be displayed as read in time. If one party uses the non-mobile phone to chat, there will be unread and read confusion.

This picture shows when chatting between IOS and computer

     

(2) Address book friends are not unified

First of all, the friends added on the web end are not recorded in the friend address book on the web end. Secondly, add friends. When user A adds a user B friend, user A's interface will display friends, but user B's address book interface will appear Buddy message lags.

When I have added my friend "Cool Morning" successfully, there is already a friend record in my interface, but my friend record does not exist in his interface. It only appears after a period of stay.

   

(3) IOS chat input box disappears or disappears

When entering the personal details interface on the right from the chat interface and then exiting to the chat interface, the chat input box is partially or completely obscured by the keyboard, resulting in the typed content message not being seen

              

(4) The message on the IOS side is turned on but not reminded, and the message reminder on the Android side cannot be turned off

When the system notification and the notification in the software are all turned on, there is still no message reminder, and the number of software messages is displayed as the number when the software is launched. It will not change with the change of the message and will always be fixed at a value

               

(5) Different platforms support different functions

• Video calls are supported on the web and applets, but not on the IOS side. Only two parties can use the applet or web at the same time to video chat. If one party uses the app, it will display that it does not support custom messages.

(6) The web group group chat interface is messy

When the group chat details are opened in group chat A, then switch to group chat B. When switching back to group chat A, the details in group chat A are displayed as the details in group chat B. There are only 4 people, but the details of the group members are the group member information in the exchange group below.

3. Predict the reason

Predicted reasons for unread unread confusion, messy address book friends, etc. may be network delays or slow system database caching mechanism. When too many users enter the system, the database processing capacity is limited, resulting in data confusion resulting in delays and errors.

The reason for not reminding the mobile phone message on the IOS side may be that the function is not perfect or there are some bugs on the IOS side that cause the function to not be implemented

The reason for the prediction of the disappearance of the input box may also be a problem on the IOS side, because asking the classmates on the Android side, they did not have such a problem, but each iPhone user has such a problem, it may be that the software and the system do not match. disappear

1.2 Interview

2. Analysis

1. Estimated working hours

The estimated time is about 5 months

2. Analysis of pros and cons

Compared with NetEase Yunxin

Disadvantages:

• NetEase Yunxin has the function of my computer, which realizes the communication between the computer and the mobile terminal, which is more convenient, and Tencent's address book and other functions cannot be realized, while NetEase Yunxin can realize the status of friends, etc. In Tencent, custom avatars are not allowed.

• Currently, Tencent only supports one-to-one videos, not intra-group videos

Advantage:

• Tencent has read and unread functions, and some people may think that read and unread functions are not very suitable, but it is still a highlight function.

• Support message withdrawal

3. Specific recommendations

• We must draw on the advantages from other software and improve our own shortcomings.

• The realization of the function of the software should be more specific. Many functions cannot be realized and have no practical value. Among them, the function settings should be consistent with the main purpose of the software design, the realization of the main functions should be more perfect, and some auxiliary functions that are not related to the main functions of the software itself should be more carefully considered Do you need this feature.

3. Recommendations and planning

If you need to use this Tencent instant messaging SDK to develop your own product:

• If you are a project manager, how can you improve and win the competition?

  • Improve the practicality of the software and reduce software bugs

  • Increase the aesthetics of the software and make it simple and elegant

  • Innovative software functions, highlighting the highlights of its own software

  • Improve one's ability

• What products are currently on the market?

  • Software with more resources such as Douban Weibo

  • Some analog chats

• What kind of function do you want to design?

  • Simulate plot characters to chat with users, the chat background is the plot itself

  • Sorting and collection of resources for various dramas

• Why do you want to do this function instead of other functions?

  • There are various chat software and various video software in the market. When a user wants to talk about the content of the plot while watching a drama, either a barrage or an external chat software, a barrage You ca n’t chat in-depth in a flash, and you ca n’t find out who likes the show during external chats. Most of the time you are chatting with your friends or people around you. If you have one, you can integrate watching videos and chat. Software, it can be solved very well.

  • There are many simulated chats in the market, most of which are themed with idol idols, etc., and few simulated chats are themed on TV plots. Many people will be curious when watching the drama. If they are in this plot, what their own approach is, this feeling can give users a feeling that they are participating in the TV series.
