PSPDFKit - App crash on creating new document

Question

I'm evaluating PSPDFKit for one of my Android app. To create a new document I'm using following code:

final File outputFile = new File(getFilesDir(), "new-document.pdf");
final PSPDFProcessorTask task = new PSPDFProcessorTask(NewPage.patternPage(NewPage.PAGE_SIZE_A4, PagePattern.LINES_7MM).build());
PSPDFProcessor.processDocument(task, outputFile);

The app crashes with following exception on the second statement above;

    E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.ammar.app.pdftest, PID: 7588

I've tried re-fetching all the dependencies but this crash is not going away.

Answer 1

This exception is generated when the native library for the PSPDFKit SDK is missing/not copied in correctly as part of your setup, or if you have not properly initialized PSPDFKit.

To initialize PSPDFKit use this line of code, preferably inside your Application#onCreate method or during activity startup.

PSPDFKit.initialize(context, YOUR_LICENSE_KEY);
