android - 致命信号 11 Android baseApi.init()

Question

在我的 android 应用程序中，我为 ocr 运行 tesseract 引擎。我已经测试了很长时间，它工作正常。今天我得到一个错误:Fatal Signal 11，它似乎在这个函数 baseApi.init() 中。我使用两种语言 eng+ell。我能做些什么来解决这个问题？我的日志文件在这里:

更新:我再次运行它，现在日志文件显示:

09-09 18:07:17.113: D/ProgressBar(9018): updateDrawableBounds: mProgressDrawable.setBounds()

问题可能与 AsyncTask 和 UI 线程有关吗？可以肯定的是它总是卡在执行baseApi.init()的25%。

更新 2:好吧，我在不同的类中运行 OCR 代码而不使用 AsyncTask 来查看问题是否来自 AsyncTask，它告诉我它不是来自 AsyncTask。问题来自 baseApi.init()。这是我的代码:

TessBaseAPI baseApi = new TessBaseAPI();
baseApi.init(languagePath, languageCode);
baseApi.setImage(bitmap);
recognizedText = baseApi.getUTF8Text();
baseApi.end();

Answer 1

最后!!!我找到了。我不知道为什么，但受过训练的数据文件有问题。我删除了它们，再次下载它们并测试我的应用程序。致命信号错误消失了，现在工作正常。
