如何在应用程序发明者中创建后台活动
我想在 appinventor 中创建一个应用程序，它可以根据解锁时晃动手机的哪一侧来左右切换屏幕。但无法弄清楚： 一个。如何让应用程序在后台运行。 b.我要买什么房产。就像当手指在屏幕上滑动时告诉手机屏幕向左或向右滚动一样。叫什么方法。我认为视图类必须用它做一些事情。没有java经验，我无法理解sdk、参考、资源等。
请帮助我，我会给你信用。 哦，我也想我可能还必须包括“活动启动器”。
I wanted to create an app in appinventor that would switch screen right/left depending on what side the phone is shaken while unlocked. But couldnt figure out:
a. how to make application run in background.
b. what property i am going for. Like what tells phone's screen to scroll left or right when finger slides across the screen. What method is called. I figured view class would have to do something with it. Having no java experience i couldn't make much sense out of sdk,refernce,resources etc.
Please help me out, i will give you credit for it.
Oh also i think i might have to include "activity starter" too.

这是应用程序发明者的问题

It's an issue for app inventor

您肯定知道，标准的 Application Inventor 2 网站是：
但是，还有另一种，它允许使用后台线程（服务）：
它具有标准上不可用的功能（官方）AI2 网站，添加任务功能，允许添加即使在屏幕关闭后仍会继续运行的任务。
不过，由于它是一个不受支持的版本，其上一次发布已经是近一年前的事了，所以我没有花时间做实验，但这可能会满足你的需求：
The standard Application Inventor 2 website, as you surely know, is this one:
However, there is another one, which allows using background threads (services):
It has a feature not available on the standard (official) AI2 website, the Add Task functionality, which allows adding tasks that will keep running even after a screen have been closed.
However, since it is an unsupported version, whose last release is dated from almost 1 year ago, I did not spent time making experiments, but this migh meet what you need:
该网站将被关闭，但之前运行得非常顺利。
整个概念基于硕士论文： https://dspace.mit.edu/bitstream/handle/1721.1/100626/932752939-MIT.pdf;sequence=1
该网站的最后一条消息类似于：谷歌改变了后台服务架构的概念，导致“任务”概念过时并妨碍其在未来发挥作用。
The website will turn down, but worked like a charm before.
The whole concept was based on a Master Thesis: https://dspace.mit.edu/bitstream/handle/1721.1/100626/932752939-MIT.pdf;sequence=1
The last message from the site was something like: Google change the concept of background service architecture which cause the 'taks' concept to obsolate and prevent to work in the future.
