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.

 

[Erel]

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

 

[blong]

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

 

[Erel]

I know what causes it, but I'm unable to reproduce it, so not sure that this will solve it. Please try.

Copy the attached JavaObject v2.07 to the internal libraries folder. Clean the project and run again.

 

[blong]

Did as requested. Added JavaObject and cleaned project still crashed.

Add a reference to JavaObject in the libraries tab. Do you see version 2.07?

 

[blong]

Is it possible to use a different version of SDK ? I have another device, which is older and runs Android 10. ZoomImageView does not crash, but the pinch in/out seems to only zoom IN, the out gesture zooms in as well. Performance is jerky and non-ideal. Obviously, Android Photos works beautifully compared to ZoomImageView.

Add a reference to JavaObject in the libraries tab. Do you see version 2.07?

It shows 2.06 ?

 

[blong]

It shows 2.06 ?

and still crashes

 

[Erel]

You are still using the old library. Make sure to copy to the internal libraries folder.

 

[blong]

JavaObject is 2.06 and from Internal rather than Additional ?

 

[blong]

Yes now have as internal library and it shows as 2.07

AND it works .... Big Thank you .... will test on other devices tomorrow.
