Get info of current visible fragment(s) in android dumpsys

Question

I'm looking a solution to determine which fragments are currently visible from dumpsys

I can get info about activities

$ adb shell dumpsys activity | grep -i run

Is there any solution for fragments or how do you determine visible fragments from dumpsys?

Answer 1

Check documentation with adb shell dumpsys activity -h. You can provide a <COMP_SPEC> parameter, adb shell dumpsys activity <COMP_SPEC>. When you give the <COMP_SPEC> parameter, you get more information on the specific component, including the visible fragments and views.

Example when Android device settings are displayed:

$ adb shell dumpsys activity com.android.settings

On my device, the command output contains:
