Android Question Error with AppoDeal, help!

There anyone who can help me and AppoDeal uses?
However I have solved, by entering the project name in the bundle id ... but now I have a big problem.
1) When I load the ADS, these do not start right away, but I have to click several times on the button to receive gift(a circle appears running but it does not see anything but sometimes it works)...This happens even if you use connection 4G phone.
2) More seriously, when entering the code in the place below, the application crashes so abnormal after having closed the ADS


This:Appodeal.setSkippableVideoCallbacks() cause the abnormal exit app.
When I solve it?

GIOCA GLOBAL
Dim Appodeal As AppodealB4A
Dim appKey As String = "mye key AppoDeal"


Sub Activity_Create(FirstTime As Boolean)
'APPODEAL
If FirstTime=True Then
Appodeal.setEventHandler("Handler")
Appodeal.setSkippableVideoCallbacks()
Appodeal.confirm(Appodeal.SKIPPABLE_VIDEO)
Appodeal.initialize(appKey, Bit.Or(Appodeal.INTERSTITIAL, Appodeal.SKIPPABLE_VIDEO))
End If

Sub imgMob_click
If Appodeal.isLoaded(Appodeal.SKIPPABLE_VIDEO) Then
Appodeal.show(Appodeal.SKIPPABLE_VIDEO)
End If
End Sub

Sub Handler_SkippableVideoLoaded()
Log("skippable video loaded")
End Sub

Sub Handler_SkippableFailedToLoad()
Log("skippable video failed to load")
End Sub

Sub Handler_SkippableVideoShown()
Log("skippable video shown")
End Sub

Sub Handler_SkippableVideoClosed()
Log("skippable video closed")
End Sub

Sub Handler_SkippableVideoFinished()
Log("skippable video shown")
End Sub

I would try:

' Appodeal.setSkippableVideoCallbacks() ' COMMENTED OR REMOVE IT

Appodeal.initialize(appKey, Bit.Or(Appodeal.REWARDED_VIDEO, Appodeal.NON_SKIPPABLE_VIDEO)) 'use this to initialize ad types

Non skippable videos are more profitable
