如何同时运行多个doAsync？

Question

我正在使用Anko库执行一些后台任务，我在前台服务中运行了doAsync。同时，我正在通过从数据库中获取数据来更新recyclerview。但是问题在于，当前台服务doAsync运行时，不会调用recyclerview更新doAsync。

我不知道为什么它不打电话，我不能同时运行多个doAsync吗？

Asynchronous vs synchronous execution, what does it really mean?

doasync runs multiple tasks in a 'first in first executed'(what you explained) sequence in one background thread(not multiple threads); so like asynctask by creating multiple instances of it you're just creating multiple tasks;

you need to start a new thread for each of your tasks if you want all the tasks to run asynchronously relative to each other;
