Works fine here (after I removed all the unused libraries).

Do you see any error in the logs?

The problem occurs when the layout is changed many times. I install it on an Android 7 device.
There are no errors, the Player_Complete event is executed.
But the screen is black.

but on Andorid 7 device black screen , sometimes it works after device reboot.

First step is to switch to B4XPages. Your current code doesn't handle the activity life cycle correctly.

I can't, my apk is more more complex.

This is only a simply example to demostrate problem.

The more complex your project the more it is important to switch to B4XPages.

Try this:

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("panelpagamentonew")
   If FirstTime
    player1.Initialize("player1")
    player2.Initialize("player2")
    player1.Prepare(player1.CreateFileSource(File.DirAssets,"video1.mp4"))  
    player2.Prepare(player2.CreateUriSource("https://html5demos.com/assets/dizzy.mp4"))
   End If

   
    exp1.Player = player1  
   
    exp2.Player = player2
   
    player1.Play
    player2.Play
   
End Sub

Different problem, with some test apk

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("panelpagamentonew")
   If FirstTime
    player1.Initialize("player1")
    player2.Initialize("player2")
    player1.Prepare(player1.CreateFileSource(File.DirAssets,"video1.mp4")) 
    player2.Prepare(player2.CreateUriSource("https://html5demos.com/assets/dizzy.mp4"))
   End If

  
    exp1.Player = player1 
  
    exp2.Player = player2
  
    player1.Play
    player2.Play
  
End Sub

I will try to migrate to B4XPages
