这尤其是关于 stackoverflow 的一个新问题。我想知道如何使用 Jodconverter 库在 android 上进行文件转换。我看到很多例子和问题，但都是基于 java 的，甚至没有回答 android 的特定问题，甚至没有官方网站。虽然我确实看到所有者自己在他发布的一个 android 应用程序中使用了该库，因此可以使用 JODconverter 在 android 上进行转换。

以下代码来自官方网站的android版本：

OfficeManager officeManager = new DefaultOfficeManagerConfiguration().buildOfficeManager();   
    officeManager.start();   
    OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);   
    try{  
        converter.convert(new File("/sdcard/tsxt.doc"), new File("/sdcard/tsx465t.docx"));   

    }catch(Exception e){  
        e.printStackTrace();  
    }  
    officeManager.stop();

我在运行时得到的崩溃的 Logcat 输出包括除 unoil 库之外的所有库（因为添加 unoil 会给我转换为 Dalvik 失败的错误）：

I think this couldn't be possibly as JODConverter needs a valid OpenOffice installation. While starting, this library tries to guess OpenOffice installation folder (most of the times, according to the Operating System, OpenOffice is located to a specific folder), but under Android, I am not sure this is possibly. I don't have an Android device, I don't know if OpenOffice is available on this OS. If it is, you have to set up the officeHome attribut (look at a org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration class if I am right)

官网的代码和你的不一样：

final LocalOfficeManager officeManager = LocalOfficeManager.install(); 
try {

    // Start an office process and connect to the started instance (on port 2002).
    officeManager.start();

    // Convert
    JodConverter
             .convert(inputFile)
             .to(outputFile)
             .execute();
} finally {
    // Stop the office process
    OfficeUtils.stopQuietly(officeManager);
}
