How To Make A Double Tap To Expand The Video Screen Using Android Adb Commands

I am trying to analyze a streaming video in my Android device. I want everything automated by scripts, because the device has to repeat the test a lot of times and I want to do it

Solution 1:

Finally I got it. First I've recorded the double-tap event and stored it into a binary file:

adb shell 
cd /sdcard/
cat /dev/input/event_X > doubletap

Do the doubletap wherever you want it, and then, end the recording with CTRL+C

The event_X is the event called sec_touchscreen. It can be got from:

adb shell getevent -p

Then, you can replay the doubletap with:

adb shell "cat /sdcard/doubletap > /dev/input/event_X"

In my case, it was tricky because it did not work executing once the replay, but two, like:

adb shell "cat /mnt/sdcard/doubletap > /dev/input/event_X"

adb shell "cat /mnt/sdcard/doubletap > /dev/input/event_X"
