While capturing the google map screenshot through uiautomatorviewer, I am getting this error.

Error:

I found the answer to this issue.

  1. Open Android folder by cmd prompt
  2. adb shell uiautomator dump
  3. adb pull /sdcard/window_dump.xml ui.uix
  4. adb shell screencap -p /sdcard/ui.png
  5. adb pull /sdcard/ui.png
  6. open uiautomaterviewer
  7. Open folder to select dump files
    A. Screenshot:
    /Users/******/Library/Android/ui.png
    B. UI XML Dump:
    /Users/******/Library/Android/ui.uix
