Android gets the instance code of the time difference between the server and the client

Generally, when we count down the goods, we will encounter the need to obtain the start time and end time of the goods from the background, and calculate the countdown from the goods to the start time and the countdown to the end time. However, only by obtaining the start time from the background and subtracting it from the time of the mobile phone system, can we obtain the countdown to the start time. That's the problem, What if the user changes the time on the mobile phone? Will there be errors? It's likely that someone can rush to buy before others start, and the experience effect is very poor. Therefore, we need to calculate not only the time difference between the start time and the current time, but also the time difference between the server and the client. After all, let's write the code:

1. Obtain and save the time difference when the project is started

2. Count down the start time in the adapter

The end time is the same as the above method, so the code will not be pasted again. I know there are many areas that need to be improved. Don't spray too much~

The above example code for Android to obtain the time difference between the server and the client is all the content shared by Xiaobian. I hope it can give you a reference and support more programming tips.
