Take a scaled screenshot via adb

adbscreen.md

Dependencies

• Android SDK in $PATH
• ImageMagick (Ubuntu: sudo apt-get install imagemagick)

Usage

$ bash adbscreen.sh a_filename

Takes a screenshot (e.g. a_filename.png) from the connected android device (or emulator, depending on what adb selects) and puts it into the working directory. The script will repaint the left part of the notification bar so that any pending notifications will be hidden.

$ bash adbscreen.sh a_filename 25

Takes a screenshot (e.g. a_filename.png) from the connected android device (or emulator, depending on what adb selects) and puts it into the working directory. The script will repaint the left part of the notification bar so that any pending notifications will be hidden. Finally the screenshot will be scaled depending on the scale parameter (e.g. down to 25% of its original size)

adbscreen.sh

#/bin/bash

filename=$1

if test $# -gt 1; then
        scale=$2
        echo "Capturing $filename.png at a scale of $scale%"
else
        echo "Capturing $filename.png"
fi

tmpfile="/sdcard/$filename.png"
adb shell screencap -p $tmpfile
adb pull $tmpfile
adb shell rm $tmpfile
convert "$filename.png" -fill black -draw "rectangle 0,0 400,48" "$filename.png"

if test $# -gt 1; then
        mogrify -resize $scale% "$filename.png"
fi
