UnsatisfiedLinkError - com.datumdroid.android.ocr.simple找不到「libjpgt.so」

Question

我是Android Studios的新手，我正在做這個OCR http://swlock.blogspot.com/2016/07/ocr-tesseract-2.html圖像轉換爲文本，但每次我拍攝圖像應用程序會關閉並得到這個錯誤。任何人都可以指導我解決這個錯誤？謝謝

這意味着* .so文件不在您的* .apk文件中。按照this stackoverflow question/answer中的步驟操作。

您可以隨時前往Build > Analyze APK...查看* .so文件是否已添加。很明顯，如果他們不在APK中，那麼沒有理由嘗試運行需要* .so文件的應用程序。
