iOS Question Background playback problem display image and title

[Ali Alsaedi]

Hi ... It does not display the title and image to controll center music player in debug and release mode!

Private Sub Application_Start (Nav As NavigationController)
    'SetDebugAutoFlushLogs(True) 'Uncomment if program crashes before all logs are printed.
    NavControl = Nav
    NativeMe = Me
    NativeMe.RunMethod("setAudioSession", Null)
    NativeMe.RunMethod("register", Null)
    Page1.Initialize("Page1")
    Page1.Title = "Page 1"
    Page1.RootPanel.Color = Colors.White
    Page1.RootPanel.LoadLayout("layMain")
    NavControl.ShowPage(Page1)

End Sub

Private Sub Page1_Resize(Width As Int, Height As Int)
   
End Sub

Private Sub Application_Background
   
End Sub


Public Sub ControlEvent (Command As String)
    Select Command
        Case "play"
            vp1.Play
        Case "pause"
            vp1.Pause
    End Select
End Sub

Sub Test1_Click
    vp1.LoadVideoUrl("https://stream-dc1.radioparadise.com/mp3-32")
    vp1.Play
    Wait For VP1_Ready (Success As Boolean)
    Sleep(500)
    artwork = NativeMe.RunMethod("createArtwork:", Array(LoadBitmapResize(File.DirAssets, "icon.png", 64, 64, True)))
    SetPlayingInfo(CreateMap("title": "Test 1", "artwork": artwork))
End Sub

Sub Test2_Click
    vp1.LoadVideo(File.DirAssets,"37470.mp3")
    vp1.Play
    Wait For VP1_Ready (Success As Boolean)
    Sleep(500)
    artwork = NativeMe.RunMethod("createArtwork:", Array(LoadBitmapResize(File.DirAssets, "icon.png", 64, 64, True)))
    SetPlayingInfo(CreateMap("title": "Radio Paradise", "artwork": artwork))
End Sub
Sub SetPlayingInfo (info As Map)
    Dim NowPlayingInfoCenter As NativeObject
    NowPlayingInfoCenter = NowPlayingInfoCenter.Initialize("MPNowPlayingInfoCenter").RunMethod("defaultCenter", Null)
    Dim no As NativeObject = info
    NowPlayingInfoCenter.SetField("nowPlayingInfo", no.RunMethod("ToDictionary", Null))
End Sub

Is this a question or do you want to shout on us?

 

[Ali Alsaedi]

I am sorry ... Why did you think so?

I run this code, but the file information is not displayed on the lock screen

 

[Erel]

Please upload the project.

 

[Ali Alsaedi]

Thank you .... This is the project file

 

[Erel]

Try it with this:

SetPlayingInfo(CreateMap("title": "Test 1", "artwork": artwork, "artist": "aaa", "MPNowPlayingInfoPropertyPlaybackRate": 1))

And test it with a non-streaming resource.

I see various discussions about this issue and it is not clear why it doesn't always work.

 

[Ali Alsaedi]

Unfortunately, it did not work
Now that it doesn't show, is there a way to delete it?(image frame)

 

[Ali Alsaedi]

Is it possible to add two events skipBackwards and skipForward to ControlEvent? How can I do this?
