Thanks for the info. Recentlty I updated libpdfium.so on 1.0.72 and it "might" introduce some incompatibility with older SDK version (I didn't confirm that).

Could you test the following versions one by one?

• 1.0.60 chromium/6406 (default_min_sdk_version=21 #145)
• 1.0.66 chromium/6517
• 1.0.72 chromium/6555

FYI: I've confirmed the existances of FPDF_InitLibraryWithConfig on the latest libpdfium.so binaries used by pdfrx:

kawasaki@red:/mnt/d/pdfrx/android/.lib/chromium%2F6555$ nm -D x86/libpdfium.so | grep FPDF_InitLibraryWithConfig
00318b79 T FPDF_InitLibraryWithConfig
kawasaki@red:/mnt/d/pdfrx/android/.lib/chromium%2F6555$ nm -D x86_64/libpdfium.so | grep FPDF_InitLibraryWithConfig
00000000003157f1 T FPDF_InitLibraryWithConfig
kawasaki@red:/mnt/d/pdfrx/android/.lib/chromium%2F6555$ nm -D arm64-v8a/libpdfium.so | grep FPDF_InitLibraryWithConfig
0000000000333464 T FPDF_InitLibraryWithConfig
kawasaki@red:/mnt/d/pdfrx/android/.lib/chromium%2F6555$ nm -D armeabi-v7a/libpdfium.so | grep FPDF_InitLibraryWithConfig
0024285d T FPDF_InitLibraryWithConfig

Every so files for Android correctly contains FPDF_InitLibraryWithConfig. I don't have any Android devices of API 22. So it's very difficult to check the actual loading behavior :(

@mmuttaqin Android 22 is too old to test on my side. It's up to you (or someone else who also need Android 22 support) to test the things on Android 22 or I can only to close the issue without fixing it.
