Hi Amit,
Sorry for the delayed response.
I tried your suggestion and used uiautomator tool and command to see the UI hierarchy.
It worked fine. I just got into another issue where when I run adb adb shell uiautomator dump /data/local/tmp/test.xml it given very small view/UI hierarchy of the activity on android emulator but when I tried the same command hitting my real device it gave the full UI hierarchy dump.
Do you have any idea of this or any pointer to share.
