Android查看任务栈

Thanks
我是从这个博客学习到的：
http://blog.sina.com.cn/s/blog_5de73d0b0102xky0.html
本文基于此博客进行一个划重点的记录。
明确问题：
即，我们如何去观察一个app进程的Activity任务栈情况。
我为什么选择这种方式：
网上还找到一种方式，就是在terminal内直接输出相关信息，但我发现这些信息又臭又长，不能很好的观察，并且也无法copy完全到其他地方观察，这种方式比较符合我的使用习惯，感觉可靠一些。
PS：
本文的重点在于，“如何查看任务栈”，所以对于后面使用Activity启动模式作为例子并没有对启动模式深挖。
若想更深层次的了解启动模式请看这篇博客:
先给出答案
C:\Users\Administrator\Desktop>adb shell dumpsys activity -p com.packagename.packagename > taskinfos.txt
划重点：
dumpsys
adb shell 核心指令，用于查看手机的运行数据。-p com.packagename.packagename
-p 后面跟的是需要观察的进程包名，你要看哪个app相关的任务栈，就跟哪一个包名。前提是你要知道该app包名。C:\Users\Administrator\Desktop> … taskinfos.txt
这个是命令输入的路径，这里是写在桌面，为什么？因为方便看，你也可以自定义路径。
验证
记不住的东西是因为你不够坚信，眼见为实，这里来个例子，我就随便打开个以前的Demo来验证。
项目基本情况
观察栈内情况
这里我简单验证3种情况：
- 俩个标准启动模式的Activity，在栈内的情况
- 2个singleTask启动模式的Activity，在栈内的情况
- 2个singleInstance启动模式的Activity，在栈内的情况
界面就一个按钮点跳转。我这里点击了按钮，前台Activity是OtherActivity
因为是打开的之前的demo，所以其他功能请无视，就关注这个跳转的button就行了。
俩个标准启动模式的Activity，在栈内的情况

这个东西这么多，具体怎么看呢？（搜索Hist关键字）
- Hist #1: ActivityRecord{edcc0b8 u0 demo.greendaotest.com.greendaotestdemo/.OtherAcitivty t1918}
- Hist #0: ActivityRecord{c25995b u0 demo.greendaotest.com.greendaotestdemo/.MainActivity t1918}
这就是当前任务栈的情况。
2个singleTask启动模式的Activity，在栈内的情况
接下来我们将俩个Activity设置为singleTask。并将OtherActivity切换至前台。

- Task id #1946
就一个栈，栈内2个Acitivty。
搜索“hist”关键字，查看到栈内情况。

这里得多唠叨下：
搜索“task id”关键字，查看有几个栈，栈内存在的acitivity信息。
这里可以看到是2个栈：
- Task id #1956 ，Task id #1953。
- 每个栈内存在一个activity，分别是。
Task id #1956
