I'm working on project, and integrated card.io and tess-two libraries. I have already owned these libraries, and use for reading national ID and other ID cards. Before upgrading to ndk-14, everything worked well. But after upgrade, i got lots of problems. I downgraded to ndk-13, but yet have these errors. Here are my logs:

The problem about libtess.so library, but i don't know why? Please help me, and ask for more details.
Here is my some essential codes from jni:
Initialize:
int res = api->Init(env->GetStringUTFChars(dataPath, 0), "aze");
if (res) {
dmz_error_log("Could not initialize tesseract");
} else {
dmz_debug_log("Initialized tesseract");
}
Getting image from card:
char *getCardNumberImage(cv::Mat cardImage) {
cv::Rect cropRect(kCreditCardTargetWidth * 76 / mmCardWidth,
kCreditCardTargetHeight * 14 / mmCardHeight,
kCreditCardTargetWidth * 24 / mmCardWidth,
kCreditCardTargetHeight * 4 / mmCardHeight);
api->SetVariable("tessedit_char_whitelist",
"0123456789");
return getOCRText(cardImage(cropRect));
}
Getting result from tesseract:
char *getOCRText(cv::Mat image) {
api->SetImage((uchar *) image.data, image.size().width, image.size().height,
image.channels(), image.step1());
// Get OCR result
char *outText = api->GetUTF8Text();
dmz_debug_log("TEXT %s", outText);
return outText;
}
I When i use training data which trained with 3.05 it works well, but when i use data which trained with 4.00 it gives me such errors. My tesseract version is 4.00 Alpha.
