        }
    eclipse 导入logger.2.1.1包

    Logger.addLogAdapter(LogAdapter adapter);
        AndroidLogAdapter：正常日志打印模式
        DiskLogAdapter: 日志保存到磁盘中不做打印日志到控制台

                                // 跳过堆栈跟踪中的某些方法调用。默认为 5
    //  .logStrategy(customLog) // (Optional) Changes the log strategy to print out. Default LogCat
                                // 更改日志策略以打印出。默认的logcat

    FormatStrategy formatStrategy = CsvFormatStrategy.newBuilder()
            .date()  // 设置保存的时间，默认data();
            .dateFormat()  // 设置保存的格式化时间,默认 yyyy.MM.dd HH:mm:ss.SSS

     Logger.addLogAdapter(new AndroidLogAdapter() {
      @Override public boolean isLoggable(int priority, String tag) {
        return BuildConfig.DEBUG;

    });
    

    Logger.clearLogAdapters();  // 清理所有的日志配置
    
    Logger.x(); 日志打印方法

            d > log.d
            i > log.i
            w > log.w
            e > log.e

4. Details
The address of the log file saved by DiskLogAdapter is the root directory/logger/
file name is named according to the format of logs_0.csv. When the file size exceeds the default setting value of 500k, the file logs_1.csv will be created.
Modifying the path needs to be modified in the source code CsvFormatStrategy.java.
The default tag for log printing is: PRETTY_LOGGER
