当我在真实设备（ZTE，Android 4.2.2）上运行以下代码时，出现错误：

    _tessApi = new TessBaseAPI();
    _tessApi.setDebug(false);
    try {
        _tessApi.init(Environment.getExternalStorageDirectory().getPath(), "chi_sim");
        _useOcr = true;
    } catch (Exception ex) {
        _useOcr = false;
    }

testRunner 中的错误：

我正在将一个项目打包到 AutoRunner.jar 中并将 jar 推送到真实设备。问题似乎是无法从设备加载 liblept.so 和 libtess.so 文件。

我在这里找到了解决方案：打开cmd然后执行：adb push ...\liblept.so system/lib和adb push ...\libtess.so system/lib（文件路径在tess-two文件夹下）

更改代码：

System.loadLibrary("lept");
System.loadLibrary("tess");

至：

System.load("/system/lib/liblept.so");
System.load("/system/lib/libtess.so");
