Android Question (Solved) R8 error with PDFium

[Alex_197]

Hi all.

I'm getting this runtime error when I using R8 with PDFium lib.

** Activity (main) Resume **
onError()
java.lang.UnsatisfiedLinkError: No implementation found for long q.e.B(int, java.lang.String) (tried Java_q_e_B and Java_q_e_B__ILjava_lang_String_2) - is the library loaded, e.g. System.loadLibrary?
