第一种方法

• stephen@ubuntu:~$ adb shell dumpsys window | grep mCurrentFocus
  mCurrentFocus=Window{510f1fc u0 com.ss.android.ugc.aweme/com.ss.android.ugc.aweme.splash.SplashActivity}

如果你想获取所有Activity栈中所有Activity时，第一种方法就不管用了。

第二种方法

hooker工作台自带打印应用所有activity名的功能

• a : 打印Activity栈的所有实例，当前界面排最前面。你可以立刻获取当前手机界面的Activity实现类、继承关系、实现接口、Activity中的所有属性值和方法声明。配合jadx动静分析效果最佳，分析Activity对象的内部情况将极快的提供逆向的线索。值得注意的是Activity中每个成员变量hooker会分配一个ObjectId，这是为了让你用c命令对内部成员变量进行扫描的。
  
  Please enter e, s, j, c or ex command.
  a: Discovering activities.
  b: Discovering services.
  c: Discovering object. eg:'c {objectId}'
  d: Object2Explain. eg:'d {objectId}'
  v: Discovering view. eg:'v {viewId}'
  e: Determines whether a class exists. eg:'e android.app.Application'
  s: Discovering classes by a class'regex. eg:'s com.tencent.mm.Message.*'
  t: Discovering offspring classes by a class'name. eg:'t com.tencent.mm.BasicActivity'
  j: Generating hooked js. eg:'j okhttp3.Request$Builder:build'
  k: Generating hooked the string generation js with a keyword. eg:'k {YourKeyword}'
  l: Generating hooked the param generation js with a param keyword. eg:'l {YourKeyword}'
  m: Discovering so module.
  ex: Exit to the upper layer. eg:'ex'
  : a #此处输入a命令回车即可打印Activity栈
