问题描述

我想以此来显示他是目前在App的用户。举例来说，如果我有活动A ， b活动，活动ç等等......如果他浏览到活动è（为前）。他应该能看到他是如何落在了对当前历史屏幕 - （从首页 - > E或从首页 - > A-> B，然后e或同样的历史是precise ..）..我已阅读生根粉活动栈开发者论坛，但有仍没有得到的方式挂接到的活动...帮助堆栈跟踪信息，请..

I want a way to show the user where he is currently in the App. Example, if I have activity A,activity B, activity C and so on...If he navigates to activity E (for ex)..He should be able to see the history of how he has landed up on the current screen--(From Home->E or from home->a->b and then e or likewise. The history to be precise..)..I have read abt the activity stack on developer forums but have still not got a way to hook up into the stack trace of the activity...Help please..

推荐答案

您可以使用的getStackTrace（）获取进行导航infromation：

You can use getStackTrace() for getting navigates infromation:

  StackTraceElement traceElement = Thread.currentThread()  
  .getStackTrace()[3];
  String logText = String.format(CLASS_METHOD_LINE_FORMAT,  
  traceElement.getClassName(), traceElement.getMethodName(),  
  traceElement.getLineNumber(), traceElement.getFileName());  
  Log.d("messg", logText);

或

猫/data/anr/traces.txt

cat /data/anr/traces.txt

但你需要有root权限来修改文件 /数据/

but You need to have root access to modify the files in /data/
