Foreground service

[vedat 2]

Hello, I want to develop a music player app on fmx. As I understand from the research I must use foreground service to make a persistent menu on the status bar for next/play/pause  musics. Do you have any document or source code that explains the usage of foreground service ? Thanks in advance

Can you provide links to the research that shows that is what is required?

That's information about foreground services. How does "a persistent menu on the status bar for next/play/pause musics" relate to it?

Well, if you look at the link https://developer.android.com/guide/components/foreground-services  it says : 

"Examples of apps that would use foreground services include the following:

• A music player app that plays music in a foreground service. The notification might show the current song that is being played."  As I understand from this document, the notification of the current song can be played/paused or you can switched to next song through that notification bar. Notification bar stays there until the service closes down. Btw thank you for your care

This does not say that the app absolutely has to have a foreground service. The notification can be created without one:

But I want to show music menu notification bar even if the app was closed. Won't the music menu bar closed once you close your app  if you don't use  something that runs on background ?

Yes.. as far as I can ascertain, if the app is closed you would need a service to ensure the notification with the controls is persistent. Here's a problem with this scenario: you will not be able to use TMediaPlayer in a service, since it relies on FMX units, including FMX.Types, because of this issue: https://quality.embarcadero.com/browse/RSP-17857 so you would need to do your own implementation (or find one), avoiding the FMX units.

This example will help you. Take a look at this.
