You need to use the instrumentation class :

Instrumentation i = new Instrumentation();
i.sendKeyDownUpSync(KeyEvent.KEYCODE_A);

This should be equivalent to a A pressed on the keyboard.

Don't forget that this method is synchronous, so you might also need to wrap it in something asynchronous. – Constantine Ketskalo Oct 18 '19 at 11:47

The following example shows how to invoke Key Back key event:

KeyEvent eventDown = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK);
KeyEvent eventUp = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK);
dispatchKeyEvent(eventDown);
dispatchKeyEvent(eventUp);
