Използвам tess-two без проблеми, но когато извикам TessBaseAPI.end(), приложението се срива. Показва се това лог съобщение.

Повече подробности:
- Случва се при нормална употреба на приложението и по време на моите тестове (използване на Espresso + Spoon)
- Използвам Samsung GT-I9300 с Android 4.3, но мисля, че се случва и на други устройства.< br> - Да, използвам конструктора по подразбиране. TessBaseAPI baseApi = new TessBaseAPI();
- Декларирах baseApi като поле в моя клас и извиках setImage и getUTF8Text няколко пъти в различна нишка (проблем?). Когато активността бъде унищожена, извиквам метода end().
- Използвам eng.traineddata, наличен тук: https://github.com/tesseract-ocr/tessdata.
Някаква идея? Има ли добър начин да освободите паметта, разпределена от tess-two?
