How can I use adb to send a longpress key event?

I can use something like:

adb shell input keyevent 4

and this will send a single 'Back' button press to my device. How can I send a longpress?

Thanks

When you want to delete something or repeat some Event or just input a lot of numbers, you can use code like the following. It will imitate a longpress on a keyboard:

adb shell input keyevent KEYCODE_FORWARD_DEL KEYCODE_FORWARD_DEL KEYCODE_FORWARD_DEL //delete 3 times


adb shell input keyevent KEYCODE_1 KEYCODE_1 KEYCODE_1 //input value '111'

You can repeat the event or input things without limits, just like a Longpress on the key. It's the same thing. You can define your own longpass and times Now

You can try this command:

adb shell input touchscreen swipe 170 187 170 187 2000

Your application position on screen is 170, 187; delay time is 2000 (ms);

Long press HOME key:

adb shell sendevent /dev/input/event2 1 172 1
adb shell sendevent /dev/input/event2 0  0 0
timeout 1
adb shell sendevent /dev/input/event2 1 172 0
adb shell sendevent /dev/input/event2 0  0 0

You can goto cmd and type adb shell getevent | find "event2" ; long press HOME key to see more.

This link discusses a similar problem, but the device in question (a Nexus One device)has the menu/home/back/search buttons as part of the touchscreen, not physical keys.

This other one appears to be more inline with injecting a physical key input, but requires accessing the *.kl file for your devices driver to determine the device, type, key-code, value-press, and value-release codes for that specific device.

However, the common link between the two appears to be 

adb shell sleep n

, where n is the length (in seconds) of the press duration.

Hopefully this might be of some use.

This might be too late to answer but surely will help others.

Please use below cmd to achieve long press.

adb shell input keyevent 5 sleep 5

Since this commit in Android 4.4 it is possibile to use:

adb shell input keyevent --longpress KEYCODE_L

This other commit further improved the behaviour.
