我使用 tess-two 没有问题,但是当我调用 TessBaseAPI.end() 时,应用程序崩溃了。显示此日志消息。

更多细节:
- 它发生在正常的应用程序使用和我的测试期间(使用 Espresso + Spoon)
- 我使用的是运行 Android 4.3 的三星 GT-I9300,但我认为其他设备也发生了。
- 是的,我使用的是默认构造器。TessBaseAPI baseApi = new TessBaseAPI();
- 我在班级中将 baseApi 声明为字段,并在不同的线程中多次调用 setImage 和 getUTF8Text(问题?)。当 Activity 被销毁时,我调用 end() 方法。
- 我正在使用此处提供的 eng.traineddata:https ://github.com/tesseract-ocr/tessdata 。
任何的想法?有没有好办法释放 tess-two 分配的内存?
