----------------------------------------------------------------
[~lehmi] We do have pdfbox-2.0.3 jar file and "org.apache.pdfbox:pdfbox:2.0.3"
as gradle dependency for android applications.
[~tilman] It is working fine if disable progaurd (minifyEnabled false) but
getting exception if we enable ProGaurd. We are using this library from long
time and it is working fine, we are just trying to enable progaurd in our
application after which we are getting this exception.
Basically we need correct ProGaurd config rules for pdfBox library for android
applications.
