Android Question moveTaskToBack in B4A

[moster67]

How can we use moveTaskToBack in B4A?

https://developer.android.com/reference/android/app/Activity.html#moveTaskToBack

or is it equivalent to Activity.Finish? (I don't think so)

You can use this code:

Dim jo As JavaObject
jo.InitializeContext
jo.RunMethod("moveTaskToBack", Array(True))

What do you use it for?

In the thread B4A ScreenRecording, I am attaching a sample app. In this sample app, there is a method which calls StartRecording. Currently users have to tap home button to get rid of the sample app activity and this get fetched in the recording. By using moveTaskToBack(), activity will move back into the background and the home screen is immediately visibile.

Of course, it is up to the users to handle this (they can implement a timer so recording does not start immediately) but I saw another app using moveTaskToBack() and I couldn't find it in B4A.

Can't you call Activity.Finish to close the recording activity (I haven't tried your example)?

I tried Activity.Finish but the video output files seemed to become corrupted and was not playable.
Note: I haven't researched why this happens with Activity.Finish but moveTaskToBack() works fine so I am cool with it
