> Failed to transform 'D:\PDFReaderApp\app\libs\itsrts-pptviewer.jar' using Jetifier. Reason: InvalidByteCodeException, message: Error processing 'com\olivephone\b\a\a.class' bytecode.. (Run with --stacktrace for more details.)
This is a known exception, and Jetifier won't be able to jetify this library.
Suggestions:
- If you believe this library doesn't need to be jetified (e.g., if it already supports AndroidX, or if it doesn't use support libraries/AndroidX at all), add android.jetifier.blacklist = {comma-separated list of regular expressions (or simply names) of the libraries that you don't want to be jetified} to the gradle.properties file.
- If you believe this library needs to be jetified (e.g., if it uses old support libraries and breaks your app if it isn't jetified), contact the library's authors to update this library to support AndroidX and use the supported version once it is released.
