Question

我从git repository http://sourceforge.net/projects/crengine/检查了coolreader 3。我尝试在eclipse中构建它，但是在运行时崩溃时出现以下错误：

应用程序Cool Reader（process.org.coolreader）意外停止。请再试一次。

以下是logcat中的红色部分：

这是函数org.coolreader.crengine.Engine.installLibrary：

private void installLibrary() {
    try {
        if (force_install_library)
            throw new Exception("forcing install");
        // try loading library w/o manual installation
        log.i("trying to load library " + LIBRARY_NAME
                + " w/o installation");
        System.loadLibrary(LIBRARY_NAME);
        // try invoke native method
        //log.i("trying execute native method ");
        //setHyphenationMethod(HYPH_NONE, new byte[] {});
        log.i(LIBRARY_NAME + " loaded successfully");
    } catch (Exception ee) {
        log.i(SO_NAME + " not found using standard paths, will install manually");
        File sopath = mActivity.getDir("libs", Context.MODE_PRIVATE);
        File soname = new File(sopath, SO_NAME);
        try {
            sopath.mkdirs();
            File zip = new File(mActivity.getPackageCodePath());
            ZipFile zipfile = new ZipFile(zip);
            ZipEntry zipentry = zipfile.getEntry("lib/armeabi/" + SO_NAME);
            if (!soname.exists() || zipentry.getSize() != soname.length()) {
                InputStream is = zipfile.getInputStream(zipentry);
                OutputStream os = new FileOutputStream(soname);
                Log.i("cr3",
                        "Installing JNI library "
                                + soname.getAbsolutePath());
                final int BUF_SIZE = 0x10000;
                byte[] buf = new byte[BUF_SIZE];
                int n;
                while ((n = is.read(buf)) > 0)
                    os.write(buf, 0, n);
                is.close();
                os.close();
            } else {
                log.i("JNI library " + soname.getAbsolutePath()
                        + " is up to date");
            }
            System.load(soname.getAbsolutePath());
            //setHyphenationMethod(HYPH_NONE, new byte[] {});
        } catch (Exception e) {
            log.e("cannot install " + LIBRARY_NAME + " library", e);
        }
    }
}

engine.java中的第837行：

 System.loadLibrary(LIBRARY_NAME);

engine.java中的LIBRARY_NAME设置为：

 static final private String LIBRARY_NAME = "cr3engine-45-15";

由于我从存储库下载了代码，因此无需任何修改即可正常工作。我不明白为什么它不起作用。

Answer 1

这些不是标准名称，因为它们缺少lib前缀。

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

这导致搜索liblept.so，这不是您拥有的文件。为您的库提供标准名称，或指定实际文件名，包括最终安装在设备上的路径

System.load(("lept") 
//rather than 
System.loadLibrary().

如果它不满意的链接错误那么没有看到您的代码只是假设您的代码尝试加载共享库 liblept.so 并且库不可用在那条路上。您使用的代码也可以在任何lib或内部包目录中包含liblept.so文件，或者您必须使用 Android-NDK生成（构建）该共享库尝试执行 { {3}}，tutorial1

android UnsatisfiedLinkError：找不到库
