Trying to build PDF reader using MuPDF library, app crashing while opening PDF

Question

Good Day, I'm trying to build PDF reader using MuPDF. Everytime when I try opening pdf in app its showing libmupdf_java.so not found and application crashed. I'm using mupdf.aar bundle, I opened bundle & checked found libmupdf_java.so in it. created jniLibs folder in main & copied armeabi-v7a & x86 .so files in it but still facing same issue. How to sort it? I'm stuck here from many weeks. please help me. I'm using samsung S10+ for android app simulation.
