Android打印不是pdf文件

Question

我想用 android 打印管理器打印一些 .txt 文件

File file = new File(Environment.getExternalStorageDirectory().getAbsoluteFile(), String.valueOf(System.currentTimeMillis()) + ".txt");
    try {
        file.createNewFile();
        FileWriter writer = new FileWriter(file);
        writer.append("какой-то текст");
        writer.flush();
        writer.close();

        PrintManager printManager = (PrintManager) getSystemService(Context.PRINT_SERVICE);
        printManager.print(file.getName(), new PrintFileAdapter(file), null);

    } catch (IOException e) {
        e.printStackTrace();
    }

这段代码抛出异常

java.lang.RuntimeException: Cannot print a malformed PDF file
  at android.print.PrintManager$PrintDocumentAdapterDelegate$MyHandler.handleMessage(PrintManager.java:815)
  at android.os.Handler.dispatchMessage(Handler.java:102)

可以打印简单的txt文档吗？

欢迎您尝试将文本文件加载到WebView，然后是printing the contents of the WebView。
