Question

当我在真实设备（中兴通讯，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。

Answer 1

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（文件路径位于tess-two文件夹下）

更改代码：

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

为：

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

java.lang.UnsatisfiedLinkError：无法加载lept
