On my end digital signature widget works properly in landscape, see:


Im using latest version 9.0.1 , i am opening a pdf document in my app to fill a form but whenever i switch to landscape mode i am not able to use the signature widget. Here is code from my project where i defined toolManagerBuilder and im also attaching a video

val mToolManager = ToolManagerBuilder.from()
.build(this@DocumentViewerActivity, pdfViewCtrl)


//pdfViewCtrl is set in layout file <com.pdftron.pdf.PDFViewCtrl


Hi, I’m having a lot of difficulty reproducing this issue. Are you able to reproduce this on our showcase app Xodo: Could you please give it a try? If you cannot reproduce in our showcase app, please provide a sample project that we can run and reproduce the issue as-is. Thanks.

hi, the issued got solved .it occurred because i was using these 2 dependencies:-
1)implementation ‘androidx.constraintlayout:constraintlayout:2.0.4’
2)implementation “”

later i changed the version of the dependencies then it worked fine.

I’ve the same issue and when i saw this comment i changed the dependencies of those implementations but still have same issue can you tell me which versions did you change the implementations?!!!

Hi Halem,

If you are running the latest version of PDFTron, you can try:

"implementation androidx.constraintlayout:constraintlayout:2.1.0"

Alternatively, you can try remove those dependencies in your app since PDFTron uses them directly.
