1 the mui development app, program used to run in the background for a period of time will be killed by the mobile phone. When it comes to app, it has a live chat function. The problem of running in the background must be resolved.
2 does mui, currently have no solution to this problem? Or to solve this problem, you must develop app in the native language.
3 how does an application like Wechat QQ not be killed by a mobile phone? even if you clear the background program and click on the app again, it will be awakened directly without having to load the initial page.
I hope you can give me some help. I feel overwhelmed.
