Finally, someone who understand what I feel at that time :) : viewtopic.php?f=4&t=7272

You need to go to the developer options and turn off Transition animation scale. Anytime you use media projection API to take screenshot (automagic built-in take screenshot action), the animation will get into the way 50% of the time.
That's why I don't use it anymore. I have root, so I use execute root command screencap -p {output}. Much faster and doesn't suffer from the transition animation scale (I still have it at 0.5x)

That worked. Thanks. I had my set to 0.5
What about takeScreenshot() on Android 9. Does it work same way?

Edit: This app works without any black boxes and transitions animation set to 1.0.
I wonder if @Martin can take a look into this.

takeScreenshot() on Pie behave just like pressing power + vol down. It will trigger default android screenshot action, not using MP-API, doesn't suffer from the transition. But it will still have the screenshot animation, which takes around 2 seconds before it disappear and it always save the file using Screenshot_yyyyMMdd_HHmmss_appname.png in /storage/emulated/0/Pictures/Screenshots/ folder.

I want no animation at all, as it is very annoying to wait for the animation. And I need to save into custom folder. My screenshot flow take screenshot only per one day folder, so it doesn't clutter up the main folder. I can even set a custom name, so all following screenshot will be saved inside that custom folder. That makes it easier to make tutorial based upon multiple continuous screenshot. When done, I simply revert back to normal folder and only need to copy the whole custom folder to PC for further processing.

I'll investigate if there's a way to prevent the black bar. Maybe this is an issue on newer Android versions since I think this did not happen on older versions of Android.
