UnsatisfiedLinkError - com.datumdroid.android.ocr.simple找不到"libjpgt.so“

Question

我是安卓工作室的新手，我正在做这个光符识别http://swlock.blogspot.com/2016/07/ocr-tesseract-2.html，其中图像转换为文本，但每次我采取图像应用程序将关闭，并得到这个错误。有人能指导我修复这个错误吗？谢谢

这意味着*.apk文件中不包含*.so文件。按照this stackoverflow question/answer中的步骤操作。

您可以随时访问Build > Analyze APK...查看是否添加了*.so文件。显然，如果它们不在APK中，那么就没有理由尝试运行需要*.so文件的应用程序。
