Adb Shell Input Events

Log the Key Event when using Adb input

The reason for you not being to see your input tap events in the getevent output is that sendevent and getevent work with Linux kernel input events and input command injects the events directly into the Android input event queue.

This (old but still useful) article has some nice diagrams illustrating the input event propagation in Android.

Unfortunately there is no easy (ready to use) way to do what you asked for. The closest thing I could think of is using dumpsys input command - it shows last 10 input events (including ones injected by the input command) in the RecentQueue: section.

ADB Key event 82 for unlocking the Android device screen is not working for KK device

You can maybe detect the SDK version and if it is kitkat and below, you can use the below code to swipe.

SDK=`adb -s $i shell getprop ro.build.version.sdk | tr -d '\r'
if (( "$SDK" <= 19 )) ; then
adb shell input swipe 200 500 200 0
fi

You can tweak the parameters against swipe to get the exact start (x,y) and end (x,y) according to the screen you are using.

Send multiple same keyevents to the adb shell?

Try to use

adb shell "input keyevent 67 && input keyevent 67"

If you need to write large scripts, you can also try this approach.
