How to make GIF from Android device screen

Question

I can capture Android device screen:

adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > adb-screenshot-$(date +%Y%m%d-%H%M%S).png

How can I squash all those images into single GIF?

Answer 1

You can use my fully working script here: android-screen-gif.sh. You simply run it with ./android-screen-gif.sh, let it record and hit Ctrl + C when you want to stop. The images will be pulled and a GIF assembled, very useful for demos/issue tracker/email! Requires convert to be on path, see the other posts here about ImageMagick.

Answer 2

Ok, I found it.

First done screenshots in single folder and then converted it all to GIF like this:

convert *.png screens.gif

Installed ImageMagick as described here.

On Mac OS X, I've installed it like this: brew install ImageMagick.

You can use the convert command of ImageMagick to combine your .png files into one .gif animation :

convert -delay 10 -loop 0 *.png anim.gif
