I following the tutorial to a T to setting up a new project with PDFNet in Android Studio,

It builds without error, but crashes on load with this error. The res folder and all libraries are in there correct locations as per the tutorial provided in the SDK.

No implementation found for long[] pdftron.PDF.PDFViewCtrl.PDFViewCtrlCreate(pdftron.PDF.PDFViewCtrl$RenderCallback) (tried Java_pdftron_PDF_PDFViewCtrl_PDFViewCtrlCreate and Java_pdftron_PDF_PDFViewCtrl_PDFViewCtrlCreate__Lpdftron_PDF_PDFViewCtrl_00024RenderCallback_2)

If you are running release build and proguard is used, please make sure the following is in the proguard file:

-keep class com.pdftron.pdf.PDFViewCtrl$RenderCallback { *; }
-keep class com.pdftron.pdf.PDFViewCtrl$PrivateDownloader { *; }
-keep class com.pdftron.filters.CustomFilter$CustomFilterCallback { *; }
-keep class com.pdftron.pdf.PDFViewCtrl$LinkInfo { *; }
-keep class com.pdftron.pdf.ProgressMonitor { *; }
-keep class com.pdftron.sdf.ProgressMonitor { *; }
-keep class com.pdftron.common.PDFNetException { *; }

Which architecture are you testing with and which sample are you running?
Are you using the latest version of the PDFNetAndroid SDK (6.5)?
Did you run “gradlew.bat setupSamples” in PDFViewCtrlProjects directory?
