时间：2021-02-12 19:50:05

如要了解功能实现,请运行app程序查看控制台日志和源代码!
* 源代码 : AcmenXD/Logger
* apk下载路径 : Logger.apk

依赖

  • AndroidStudio
    allprojects {
            repositories {
...
                maven { url 'https://jitpack.io' }
            }
    }
     compile 'com.github.AcmenXD:Logger:1.3'

功能

  • 设置Logger开关
  • 设置Logger显示级别
  • 支持java任意类型的日志输出,不在局限于String类型
  • 支持Throwable日志格式化输出
  • 支持json格式输出
  • 支持xml格式输出
  • 支持日志追加到本地文件
  • 支持Android Monitor中点击日志,跳转到调用代码位置

配置

在Application中配置

/**
 * 初始化
 * context必须设置
 */
Logger.setContext(context);
/**
 * 设置Log开关,可根据debug-release配置
 * 默认为true
 */
Logger.setOpen(false);
/**
 * 设置Log等级, >= 这个配置的log才会显示
 * 默认为Log.VERBOSE = 2
 */
Logger.setLevel(Log.VERBOSE);
/**
 * 设置本地Log日志的存储路径
 * 默认为sd卡Logger目录下
 * Environment.getExternalStorageDirectory().getAbsolutePath() + "/Logger/"
 */
Logger.setPath(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Log/");

使用 -> 以下代码 注释很详细、很重要很重要很重要!!!

/**
 * v可替换成d/i/w/e/a,对应不同等级的日志
 * test可替换成java任意类型
 */
Logger.v("test");
// MainActivity.java:28 可点击跳转到对应代码行
