Is there a way to do a task when an app is placed in the background?

[ROY_BIV]

I made a text editor for Android. I made a small list, brought up Firefox, and then when I went back to the editor what I typed was gone. Is there a way to make it so that when the editor is placed in the background I can save the contents of the textbox, and when it's back in the foreground I can load the file back into the textbox?

Use the ActivityChanged event from the tools extension

App Inventor Extensions: Tools | Pura Vida Apps

If state = pause

If state = resume
Then get the data again from TinyDB

Here is an extension to get the activity lifecycle state of an app. So e.g. whether an app is switched in the background and / or in idle (sleep) mode.

save it with TinyDB in the ActivityLifecycle.Stop event and get TinyDB in the ActivityLifecycle.Resume event.

OK, I used the Tools Extension checking on the state. Works great, thank you.
Seems odd to me that the example uses the math compare function with text, but I guess the math = and Compare Texts = works the same.
