Push is an indispensable function of mobile apps. This time I need to study it because of the company project. Since push is usually written on the server side, it is a headache for Javaweb programmers who do not know Android to write a complete demo. So I will write an example from beginning to end here for reference. Since I don’t understand Android, I just made a demo from Baidu because of the project needs. There are many shortcomings in it and I don’t want you to correct me.
1. First, let’s briefly introduce what Aurora Push is
①Why push is needed: In order to solve the problem of data synchronization, there are two commonly used methods on mobile platforms. One is to regularly query the data on the server, also called Polling, and the other is to maintain a long TCP connection between the mobile phone and the server. When the server has data, it is pushed to the client in real time, which is what we call Push. Because it is technically difficult to maintain long connections under mobile networks when doing push, and when the number of users increases, many servers are needed to maintain long connections, and the cost is also very high. Therefore, we need a third-party jar package to support our push service. If you want to know more, please refer to the official documentation of Aurora Push.
②The popular answer of Jiguang Push: It is to send the content that needs to be pushed to the Jiguang Push server by calling the jpush API. The Jiguang Push server chooses to push it to the specific app based on the content we have pushed in the past.
2. Source code
Server code:
Android client code:
The Android environment is: ADT+SDK+ eclipse
ADT download:
SDK download:
The required JDK environment installation will not be described one by one.
Note: The code can be imported directly and only needs to be changed in a few places, which will be explained later. First, I will teach you how to set up the Android environment and ensure that the code can be imported successfully
3. Operation steps
① Install the plug-in
After this step is completed, the page will switch to the Android development interface, and there will be two more things on the page
## ③ Then import the Android project (the server-side project will not be described how to import)
Right-click in the blank space of the project list - select import - and then operate as shown
Then run the Android program (it is best to plug in the data cable--turn on the USB debugging of the phone--and then go back to the phone when the program is running)
Specific You can download it from Baidu.
4. How to use Aurora Push (you must register an account on the official website)
Please refer to Baidu for specific usage, or refer to the official website. The following are the main screenshots
appkey and master secret will be used later
5. Modify the Android configuration file and change the appkey to the appkey of the application you added
6. Server code display, the codes are all commented, so I won’t explain them one by one.
Only use these three codes
## Change #APPKET and MASTERSECRET to the strings generated when you added the application in Jiguang Developer Service

After running the server code, the phone will receive the following notification:
In fact, the server sends the notification to the Aurora server through the uniquely identified appkey and master secret, and the server then forwards it to the corresponding app (appkey is also configured in the configuration file of the above app)
There are so many specific operations. It may not be very detailed, but there are too many steps, so I won’t take screenshots one by one. Here I only give most of the details. direction.
