Working with Hierarchy Viewer

#Hierarchy Viewer allows you to debug and optimize your user interface.
#It provides a visual representation of the layout's View hierarchy (the Layout View) and a magnified inspector of the display.

# Connect your mobile device to your computer.

# Open your application in Android Studio, build the source, and run it on your device. (debug application only)

# From Android Studio, start the Android Device Monitor: Tools > Android > Android Device Monitor.

# Allow USB Debugging on your phone (if asked).

# Make sure your device and the package for your application are showing in the Devices (DDMS mode) or Windows (Hierarchy Viewer mode) tab. You can choose Window > Reset Perspective to get back to the default arrangement.

# In Android Device Monitor (ADM), in the menu bar, choose Window > Open Perspective, and in the popup click Hierarchy View.
