How to use

You need to know digitizer device input number, which is specific to every device and ROM.

Use command

adb shell getevent -l

and move finger on screen. You will see something like

/dev/input/event2: EV_SYN       SYN_REPORT           00000000
/dev/input/event2: EV_ABS       ABS_MT_WIDTH_MAJOR   00000014
/dev/input/event2: EV_ABS       ABS_MT_POSITION_X    00000247
/dev/input/event2: EV_ABS       ABS_MT_POSITION_Y    0000030c
/dev/input/event2: EV_ABS       ABS_MT_TOUCH_MAJOR   0000001a
/dev/input/event2: EV_ABS       ABS_MT_TOUCH_MINOR   0000000e
/dev/input/event2: EV_ABS       003c                 ffffffb3

In your case device you are looking for has number 2.

You can now start screen capturing. Download latest scrollscreenshot binary, unlock screen, start app you want to scroll-capture and type (replace 2 by your device input number):

java -cp scrollscreenshot-latest.jar com.pgssoft.scrollscreenshot.ScrollScreenShot -i 2

If eveything goes well, you will get file out.png with something like:

Left-to-right mode will give you something like this:

Todo:

scrolling in all 4 directions
automatic detection of scroll area edge
