Android Question Application in background event

[Emme Developer]

Hi to all! Is there a way to know when application goes in background? I want to stop mediaplayer when app goes in pause (i know i can put a check in each activity, but i want only one sub to manage all).

An interesting thing can be this: https://stackoverflow.com/a/44461605/2684

Many thanks

create a sub in the starterservice and call this sub from each activity.

Yes but this means that i need to add a sub in each activity. If i have 200 activities, i need 200 sub in activity.pause. I think this is not the best practice to achieve what i want

You can see if your App is in the foreground with this Library

In this case this means that i need a timer that every x seconds check the state of the app, but if i can avoid this solution is a good thing

If your App goes in the background it should raise Activity_pause

it should raise Activity_pause

it does. But he dont want to add code to his 200 activities to inform the service. I would do it...

From my side: good luck to him; i´m out here.

If you declare a MediaPlayer in the Starter service:

Sub Process_Globals
    Public mp As MediaPlayer
End Sub

in each activity:

Sub Activity_Pause (UserClosed As Boolean)
    Starter.mp.Pause
End Sub

Sub Activity_Resume
    Starter.mp.Play
End Sub

To write simple program which enumerates all .bas/.b4a files and inserts a line after Activity_Pause, requires 15 minutes maximum

It would be even easier if you could use Quick Search - Replace With this way:

Sub Activity_Pause (UserClosed As Boolean) [special char] line to add

where [special char] should be a char for "new line" (CRLF) and you could get:

Sub Activity_Pause (UserClosed As Boolean)
line to add


Also I think that soon we will have the possibility to create activity templates, as it is currently possible with classes.

Guys thanks for all answers, but the problem is not to waste time to write a sub for each activity. Main problem is that i think is unbelievable that there is not a way to create a single event (so a single exit/entry point) to see the status of the app
