my app just crashes.

Please describe your issue and provide steps to reproduce it:

Updated the manually using the aar files using:

  implementation files('libs/pdftron.aar')
  implementation files('libs/tools.aar')

in the gradle file

Please provide a link to a minimal sample where the issue is reproducible:

Hello, I’m AiRon, an automated tech support bot :robot:
While you wait for one of our customer support representatives, I can help you with your question.


The error you are encountering, specifically the SIGSEGV error, indicates a segmentation fault, which often occurs when the application tries to access a memory location that it is not supposed to. In the context of using Apryse’s PDFTron library, this could be due to an issue with the integration of the library, incorrect initialization, or an incompatibility with the newer version.

Some things you can try:

  • Ensure that the PDFNet library is properly initialized before any PDF operations are performed. This is crucial for the library to function correctly.

  • Verify that you are using compatible versions of the pdftron.aar and tools.aar files. Mismatched versions can cause runtime errors.

  • Check for any proguard or R8 rules that might be affecting the library, especially if you are using any code obfuscation tools.

  • Ensure that all necessary permissions are granted in the Android manifest, particularly if the library requires access to external storage or other resources.

  • Review any recent changes made during the update process that might have affected the library’s integration.



Here are some resources that might help you:


Hopefully, this helps you solve your problem while you wait for a human to get back to you.

You have to set up an emulator or have a device that supports 16KB page sizes that will reproduce the issue (instructions here):

I have attached the sample project link that reproduces the issue using the standard PDFTron lib:

Thank you
