Question

我正在使用OCR android。从谷歌搜索获得样本并使用android tesseract。我把项目作为库并参考了另一个项目但是，当我运行项目时，它在Logcat中显示以下内容

我认为我的android.mk有问题。请帮我修复错误。

Answer 1

异常原因是，

System.loadLibrary(“lept”);

问题是 liblept.so （共享库）文件在特定库路径上找不到。在没有看到您的代码的情况下，只是假设您的代码尝试加载共享库 liblept.so ，并且该库在该路径中不可用。

您使用的代码也是在任何lib或internal package directory中都有 liblept.so 文件，或者您必须使用以下方法生成（构建）该共享库的 Android的NDK 即可。
