There was a bug in an older Android APK, where it was not loading the correct native library in some case. As a workaround for this APK bug we had to rename our armv7 library to libPDFNetC-v7a.so.

Therefore, all our native libs are called libPDFNetC.so, regardless of architecture, except for armv7, which is called libPDFNetC-v7a.so.

You can see this by looking in the /lib/[full|standard]/armeabi-v7a folder.

Most likely your project (gradle) is configured to always load libPDFNetC.so and therefore on this ASUS device the wrong architecture is being loaded.

Please take a closer look at the gradle files provided with the CompleteReader or PDFViewCtrl sample projects on how to handle this special case.
