I prefer parsing results of dumpsys window windows over dumpsys activity
adb shell dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'
Keyguard or Recent tasks list used to not show up as Activities but you were able to see them with mCurrentFocus. I have explained why in this answer.
Android Q broke most of these for me. Here's a new one that seems to be working (at least on Android Q).
adb shell "dumpsys activity activities | grep mResumedActivity"
Output looks like:
mResumedActivity: ActivityRecord{7f6df99 u0 com.sample.app/.feature.SampleActivity t92}
Edit: Works on Android R for me as well
dumpsys window windows gives more detail about the current activity:
adb shell "dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'"
mCurrentFocus=Window{41d2c970 u0 com.android.launcher/com.android.launcher2.Launcher}
mFocusedApp=AppWindowToken{4203c170 token=Token{41b77280 ActivityRecord{41b77a28 u0 com.android.launcher/com.android.launcher2.Launcher t3}}}
However in order to find the process ID (e.g. to kill the current activity), use dumpsys activity, and grep on "top-activity":
adb shell "dumpsys activity | grep top-activity"
Proc # 0: fore F/A/T trm: 0 3074:com.android.launcher/u0a8 (top-activity)
adb shell "kill 3074"
