couldn't find "librdpdf.so" after update 3.52.5

I'm having problems after updated to version 3.52.5. If I uninstall my previous app app version (With old radaee version) and install the new one (radaee 3.52.5) it works perfectly, but if I update my app version without uninstalling, it shows this message after openning a pdf file.

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathListzip file "/data/app/br.com.myappb17EaP90OFr0TG43ONgyug==/base.apk"],nativeLibraryDirectories=[/data/app/br.com.myapp-b17EaP90OFr0TG43ONgyug==/lib/arm, /data/app/br.com.myapp-b17EaP90OFr0TG43ONgyug==/base.apk!/lib/armeabi-v7a, /system/lib, /vendor/lib] couldn't find "librdpdf.so"

I don't have any idea on how to fix it, can anyone help me please?

Tks,
Thiago

on Android Studio project.
librdpdf.so shall placed in directory "$PDFSample\ViewLib\src\main\jniLibs"
where "$PDFSample" is root directory of the project.
in this directory you shall has 4 subdir:"arm64-v8a","armeabi-v7a","x86","x86_64"
each subdir has "librdpdf.so"

sorry, just better saw details of your problem.
this issue not happen on our app.
i recommand that your app do not remove library for "armeabi-v7a".
some old device not support "arm64-v8a".
