S1.添加依赖 compile \'com.elvishew:xlog:1.4.0\'或导入library源码库；

S2.初始化log；

S3.调用log；

 

API：

初始化
LogConfiguration config = new LogConfiguration.Builder()
    .logLevel(BuildConfig.DEBUG ? LogLevel.ALL             // Specify log level, logs below this level won\'t be printed, default: LogLevel.ALL
        : LogLevel.NONE)

    .addObjectFormatter(AnyClass.class,                    // Add formatter for specific class of object
        new AnyClassObjectFormatter())                     // Use Object.toString() by default
    .addInterceptor(new BlacklistTagsFilterInterceptor(    // Add blacklist tags filter
        "blacklist1", "blacklist2", "blacklist3"))
    .addInterceptor(new MyInterceptor())                   // Add a log interceptor
    .build();

Printer androidPrinter = new AndroidPrinter();             // Printer that print the log using android.util.Log
Printer consolePrinter = new ConsolePrinter();             // Printer that print the log to console using System.out
Printer filePrinter = new FilePrinter                      // Printer that print the log to the file system
    .Builder("/sdcard/xlog/")                              // Specify the path to save log file
    .fileNameGenerator(new DateFileNameGenerator())        // Default: ChangelessFileNameGenerator("log")
    .backupStrategy(new NeverBackupStrategy())             // Default: FileSizeBackupStrategy(1024 * 1024)
    .logFlattener(new MyFlattener())                       // Default: DefaultFlattener
    .build();

XLog.init(                                                 // Initialize XLog
    config,                                                // Specify the log configuration, if not specified, will use new LogConfiguration.Builder().build()
    androidPrinter,                                        // Specify printers, if no printer is specified, AndroidPrinter(for Android)/ConsolePrinter(for java) will be used.
    consolePrinter,
filePrinter);
log打印：
XLog.d("Simple message")
XLog.d("My name is %s", "Elvis");
XLog.d("An exception caught", exception);
XLog.d(object);
XLog.d(array);
XLog.json(unformattedJsonString);
XLog.xml(unformattedXmlString);

S2.初始化logutils；

S3.调用log方法；

API:

初始化
LogUtils.getLogConfig()
                .configAllowLog(true)
                .configTagPrefix("MyAppName")
                .configShowBorders(true)
                .configFormatTag("%d{HH:mm:ss:SSS} %t %c{-5}")

# 支持写入日志到文件
 LogUtils.getLog2FileConfig().configLog2FileEnable(true)
                // targetSdkVersion >= 23 需要确保有写sdcard权限
                .configLog2FilePath("/sdcard/项目文件夹/logs/")
                .configLog2FileNameFormat("%d{yyyyMMdd}.txt") 
                .configLogFileEngine(new LogFileEngineFactory());

// 输出字符串
LogUtils.d("12345");

// 输出参数

// 输出异常
LogUtils.d(new NullPointerException("12345"));

// 输出对象
Person person = new Person();
person.setAge(11);
person.setName("pengwei");
person.setScore(37.5f);
LogUtils.d(person);

// 对象为空
LogUtils.d(null);

// 输出json（json默认debug打印）
String json = "{\'a\':\'b\',\'c\':{\'aa\':234,\'dd\':{\'az\':12}}}";
LogUtils.json(json);

// 打印数据集合
List<Person> list1 = new ArrayList<>();
for(int i = 0; i < 4; i++){
    list1.add(person);
}
LogUtils.d(list1);

// 打印数组
double[][] doubles = {{1.2, 1.6, 1.7, 30, 33},
                {1.2, 1.6, 1.7, 30, 33},
                {1.2, 1.6, 1.7, 30, 33},
                {1.2, 1.6, 1.7, 30, 33}};
LogUtils.d(doubles);

// 自定义tag
LogUtils.tag("我是自定义tag").d("我是打印内容");

// 其他用法
