"hierarchyviewer" is one tool present in the the SDK that gives the
hierarchy of views present in the current visible window, that is
working on the simulator or I think needs root permission on actual
device to work.
After studding it I get to know that after opening "hierarchyviewer"
it starts a service named "window" and does some port forwarding to
communicate with it through sockets.
This is what I have done:
1) Open emulator and some screen having view components e.g. Settings
2) open "hierarchyviewer"
3) Open DOS (I am using windows) enter the command: "telnet localhost
4939"
4) When telnet connection gets established enter: "DEBUG ffffff"
NOTE: telnet connection will get establish only when hierarchyviewer
is open (I dont know why).
5) After this I am getting all the properties of all components in the
screen.
eg. the properties of one component i.e. title bar of setting window
is:

here mText=8,Settings in second line shows the text property of this
TextView
This is actually what I need but the problem is speed this "DUMP
ffffffff" command gives the output very slow.
What I want to create is Screen flow in:
e.g. For Settings
Settings
|------------> Wireless & networks
| |------------->Airplane Mode
| |------------->Wi-Fi
| |------------->Wi-Fi settings
| | |------------->Wi-
Fi
| | |-------------
>Network notification
| | |------------->Add
Wi-Fi network
|
| :
|
| :
| |------------->Bluetooth settings
| |------------->VPN settings
| :
| :
|------------> Call Settings
| |------------->Fixed Dialing Numbers
| |------------->Voice mail service
| |------------->Voice mail settings
| :
| :
|------------> Sound
| |--------------> :
| :
|------------>Display
:
:
Now I am facing following problems will someone please help me in
those:
1) Data comming from "DEBUG ffffffff" command is slow and telnet
connection does not gets connected without opening hierarchy viewer.
2) what are the services provided by command "service call window"
inside android shell and how can I use them either through command
line or programatic way?
3) If I will create a Deamon or background service, How can I get the
same data or similar data which will help me creating screen flow?
4) If possible then how can I use
android.app.ActivityManager.RunningTaskInfo.topActivity or
Context.getSystemService(Context.WINDOW_SERVICE) to create Screen flow
as shown above.
5) Can I somehow use "dumpsys window" command to get my desired data?
6) How can I access "Activity stack"(Back stack) directly which holds
activities in background (if needed)?
7) If possible please suggest any other way or solution to create the
screen flow as shown above.
