查看wake_lock状态的命令

see list of wakelocks here:

adb
shell "cat /sys/kernel/debug/wakeup_sources"

use below adb command to require a wake lock

adb shell "echo mylock > /sys/power/wake_lock"

Then, you can use below command to watch if this lock is active. You will see the time column continuously change, it means the wake lock is active

watch -n 1 'adb shell "cat /proc/wakelocks" | grep mylock'

Now, use this adb command to release the wake lock

adb shell "echo mylock > /sys/power/wake_unlock"

Then, check it again, the time column will freeze, it means the wake lock is non active

watch -n 1 'adb shell "cat /proc/wakelocks" | grep mylock'

You can use the same technique to observe the wake lock you acquire in the code.

Is there any way to see the active wakelocks?Run

adb
shell dumpsys power
