Android printing not pdf files

Question

I want to print some .txt files with android print manager

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();
    }

this code throws exception

java.lang.RuntimeException: Cannot print a malformed PDF file

欢迎您来尝试文本文件加载到一个WebView ，然后打印的内容WebView 。
