I'd like to compare the screen of my devices (many) so I'm using AndroidViewClient tool to get the hierarchy of my screens with the dump command in a terminal.
However, my devices are all linked with my computer at the same time, and the dump command seem to work on only one device. So when I use the command, I get the dump of the first device in the device list when I use adb devices.
My goal is to compare screens. So what I want is to specify which device I want to use for my dump in the terminal (and then doing it for all my devices to compare).
Is there a solution of this ? because the only solution I found yet is to make an adb -s [device serial_number] shell uiautomator dump, which offer the possibility to chose which device we want to use among those who are attached, but it produce an xml file (and this is why I need AndroidViewClient's dump, because I don't want the xml file).
In other words, is there a way to specify a device with the dump command in a terminal without disconnecting my USBs successively (keep only one device connected at the same time) ?
Thank you very much in advance !
If I understand correctly, you want to dump different devices that are already available through adb.
Getting help you can see that dump accepts an optional command line parameter which is the serialno
$ dump --help
usage: dump [OPTION]... [serialno]
...
You can also take a look at --multi-device option for culebra that can generate tests that run on many devices at the same time.
