使用带有日志行编号的木材在安卓系统中更好地登录

在/app/build.gradle文件中

implementation 'com.jakewharton.timber:timber:4.7.1'

在应用程序类中

Timber.plant(new Timber.DebugTree() {
                @Override
                protected @Nullable String createStackElementTag(@NotNull StackTraceElement element) {
                    return super.createStackElementTag(element) + ":"+element.getLineNumber();
                }
            });

如何使用：

Logg.e("====== log here ==========")

结果:

object Logg {
  private fun tag(): String? {
    return Thread.currentThread().stackTrace[4].let {
      "App# ${it.className.substringAfterLast(".")}.${it.methodName}(${it.fileName}:${it.lineNumber})"
    }
  }

  fun v(msg: String?) {
    Log.v(tag(), "" + msg)
  }

  fun d(msg: String?) {
    Log.d(tag(), "" + msg)
  }

  fun i(msg: String?) {
    Log.i(tag(), "" + msg)
  }

  fun w(msg: String?) {
    Log.w(tag(), "" + msg)
  }

  fun w(e: Throwable?) {
    Log.w(tag(), "" + e?.localizedMessage)
  }

  fun w(e: Exception?) {
    Log.w(tag(), "" + e?.localizedMessage)
  }

  fun e(msg: String?) {
    Log.e(tag(), "" + msg)
  }
}

Logg.e("====== log here ==========")
