Я загрузил последнюю версию tesseract (tess-two), я следил за тем, что написано в основном в Интернете, как интегрировать библиотеки с проектом, однако я заметил, что в последней версии tess-two есть ndk- связанные с bulid в build.gradle, поэтому создание libarires я ушел в андроид-студию с так называемым успехом. Вот build.gradle Тесс-два:tesseract dlopen не удалось в студии android

С использованием инструмента nm, прилагаемого вместе с android ndk, см.:
nm: ./x86_64/liblept.so: no symbols
однако readelf:
readelf -a ./x86_64/liblept.so | grep png_set_longjmp_fn
00000027add0 084900000007 R_X86_64_JUMP_SLO 0000000000000000 png_set_longjmp_fn + 0
это не имеет значения Wheter я смотрю в ЛИЭС/x86_64 или ЛИЭС/armXX или ЛИЭС/MIPS, я получил за нм всегда не символ и readelf я получил выход, как описано выше.
Я открыл файл apk, и все библиотеки там.
Любые идеи, что я сделаю, чтобы заставить все работать?
