Can I hang up a call programmatically in android?

Question

I hope to block some crank call, so I need to hang up some call programmatically in android.

The following fragment is from How to hang up outgoing call in Android?<

Answer 1

If you are in JUnit test then this is how;

mInstrumentation = InstrumentationRegistry.getInstrumentation();
mInstrumentation.getUiAutomation().executeShellCommand( "input keyevent " + KeyEvent.KEYCODE_ENDCALL );

It may work also from outside the test but I haven't tried it.
