How to programmatically take a screenshot in Android?

Question

Android

I could not find anywhere a seemingly simple Java code snippet for Android that would take a screenshot of the entire screen, i.e. we need a method without parameters, returning a byte array of the screenshot.

For most manufacturers, press the lock button and volume
down at the same time On Samsung, press the physical home button and volume down at the same time.
For some manufacturers, you can also press and hold the recent applications button, or take a screenshot from the device’s power menu (2-3 seconds hold the lock button)
