阅读他人代码时，往往会打日志分析实际运行流程
查看输出日志时，我们希望能够快速定位到某个文件的某一行
更有甚者，我们希望观察某个方法在运行时的调用过程，即打印出堆栈信息
但不能所有日志都打印堆栈信息，不然会影响输出体验
每次都要输入TAG,可否不用输入TAG呢
这些需求，使用OkLog爽爽的搞定！
在Android 工程根目录的grade文件中添加仓库：
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
在你的app模块里引入依赖：
dependencies {
implementation 'com.github.Oterman001:OkLog:{latestVersion}'
}
latestVersion的值为TAG的最新值；
以下代码仅供参考，可自定义；
private void initLog() {
OkLog.syncIsDebug(this);
LogConfig logConfig = new LogConfig.Builder()
.logLevel(OkLog.isDebug() ? LogLevel.ALL : LogLevel.OFF)
.formatJson(true) // 是否格式化json数据
.printCrash(true) // 是否打印崩溃
.detectANR(false) // 是否检测anr
.tag("xsuper")
.build();
// 输出到文件中 输出到文件中要写文件权限
// FilePrinter filePrinter = new FilePrinter
// .Builder("supperapp", this)
// .logConfig(logConfig)
// .build();
// 输出到控制台
ConsolePrinter consolePrinter = new ConsolePrinter();
OkLog.init(this, logConfig,consolePrinter);
}
当你在代码里进行如下的打点Log时
OkLog.v("onCreate:不打印堆栈深度，没有tag，居然可以不传tag，默认tag由初始化时配置");
OkLog.v("onCreate:堆栈深度为2", 2);
OkLog.v("onCreate:堆栈深度为5", 5);
OkLog.v(TAG, "传入tag,，传入tag，不用默认tag，打印1级堆栈深度！", 1);
OkLog.v(TAG, "传入tag,打印3级堆栈深度！！", 3);
OkLog.v(TAG, "传入tag,打印100级堆栈深度！！", 100);
OkLog.v(TAG, "传入tag,这是一个json字符串！！！json={\"level\": \"较不适宜\",\"name\": \"wash_car\","
+ "\"sugg\": \"不适合洗车，未来24小时内有雨，雨水可能会再次弄脏你的车\"}", 100);
OkLog.v("这里是一个异常！",new Throwable("哈哈哈，异常来啦！"));
控制台输出结果
