Concepts and Jetpack Compose implementation
The Layout Inspector in Android Studio lets you debug the layout of your app by showing a view hierarchy where you can inspect the properties of each view. With the Layout Inspector, you can compare your app layout with design mockups, display a magnified view of your app, and examine details of its layout at runtime. This is especially useful when your layout is built at runtime rather than entirely in XML and the layout is behaving unexpectedly.
View Attribute Inspection
Layout Inspector requires the following global setting to function properly:
adb shell settings put global debug_view_attributes 1
This option generates extra information for inspection on all of the processes on the device.
Layout Inspector automatically enables the setting when started. This causes the
current foreground Activity to restart. You will not see another Activity
restart unless the flag is manually disabled on the device.
To disable the flag, run the following adb command:
adb shell settings delete global debug_view_attributes
Alternatively, turn off Enable view attribute inspection from your device's developer options.
