在AndroidManifest文件中添加了
<application
android:requestLegacyExternalStorage=“true”

使用了最新的logUtils文件

public static void writeToFile(String text) {
        //开始写入
        FileOutputStream fileOutputStream = null;
        BufferedWriter bufferedWriter = null;
        try {
            //文件路径
            String fileRoot = Environment.getExternalStorageDirectory().getPath() + "/Meet/";
            String fileName = "Meet.log";
            // 时间 + 内容
            String log = mSimpleDateFormat.format(new Date()) + " " + text + "\n";
            //检查父路径
            File fileGroup = new File(fileRoot);
            //创建根布局
            if (!fileGroup.exists()) {
                fileGroup.mkdirs();
            }
            //创建文件
            File fileChild = new File(fileRoot + fileName);
            if (!fileChild.exists()) {
                fileChild.createNewFile();
            }
            fileOutputStream = new FileOutputStream(fileRoot + fileName, true);
            //编码问题 GBK 正确的存入中文
            bufferedWriter = new BufferedWriter(new OutputStreamWriter(fileOutputStream, Charset.forName("gbk")));
            bufferedWriter.write(log);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
            e(e.toString());
        } catch (IOException e) {
            e.printStackTrace();
            e(e.toString());
        } finally {
            if (bufferedWriter != null) {
                try {
                    bufferedWriter.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
