capture android device screenshot with adb & perl

Question

I tried the one liner solution to capture screenshot via adb and the file is created successfully on PC but it is unreadable:

 C:\Program Files\Android\android-sdk\platform-tools>adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > c:\users\utilisateur\desktop\android_screenshot1.png

enter image description here

The file seem to be correct but I think the Magic is not correct: enter image description here

EDIT: The same issue happened with Git Bash for Windows.

You must be doing something else wrong. It produces valid `PNG` files on my system. As does `sed` - `adb shell screencap -p | sed "s/\r\r$//g" > test.png` — Alex P., Apr 11 '15 at 06:03
@AlexP.: Same error; P.S: I am using Strawberry Perl (64-bit) 5.20.2.1-64bit on Windows 7 Pro SP1 x64 and latest Android SDK. — M. A., Apr 11 '15 at 13:45
When using **screencap -p /sdcard/xxx.png** it works perfectly. — M. A., Apr 11 '15 at 13:45

@Passella answer worked for me with a little tweaking:

adb shell screencap -p "/mnt/sdcard/output.png" && adb pull "/mnt/sdcard/output.png" "C:\output.png" && adb shell rm "/mnt/sdcard/output.png"

I had to quote the paths and replace | with &&.

Also, if you are using a Genymotion simulator, it's better to use its own adb:

C:\"Program Files"\Genymobile\Genymotion\tools\adb shell screencap -p "/mnt/sdcard/output.png" && C:\"Program Files"\Genymobile\Genymotion\tools\adb pull "/mnt/sdcard/output.png" "C:\output.png" && C:\"Program Files"\Genymobile\Genymotion\tools\adb shell rm "/mnt/sdcard/output.png"

Try this:

adb shell screencap -p /mnt/sdcard/output.png | adb pull /mnt/sdcard/output.png C:\output.png | adb shell rm /mnt/sdcard/output.png
