Android Question ZoomImageView and Android 16

[blong]

I downloaded and tried the B4A example which is a simple map of the world. I am using Android 16 phone, with SDK set at 33 however the simple app crashes with an

java.lang.ClassCastException: Couldn't convert result of type java.lang.Boolean to java.lang.String

the moment I try to pinch the image..

Any help appreciated.

Are you running the example as-is? Please post the full error message and the relevant code.

Yes just ran the example without any changes. The world map appears but the moment I try and pinch the image it crashes. Running in debug mode.

I did get a warning message when first installing app that it was designed in an earlier version of Android... if this is relevant.

Full simple coded example

#Region Shared Files
#CustomBuildAction: folders ready, %WINDIR%\System32\Robocopy.exe,"..\..\Shared Files" "..\Files"
'Ctrl + click to sync files: ide://run?file=%WINDIR%\System32\Robocopy.exe&args=..\..\Shared+Files&args=..\Files&FilesSync=True
#End Region

'Ctrl + click to export as zip: ide://run?File=%B4X%\Zipper.jar&Args=ZoomIVExample.zip

Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private ZoomImageView1 As ZoomImageView
End Sub

Public Sub Initialize
    
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    ZoomImageView1.SetBitmap(xui.LoadBitmap(File.DirAssets, "Wkipedia_blank_world_map.jpg"))
End Sub

Private Sub ZoomImageView1_Click
    Log("Click")
End Sub

I tested this one, https://www.b4x.com/android/forum/threads/zoomimageview.164526/#post-1008679
and it seems to work just fine
