Describe the bug

I have a keypad phone，I need to tamper with the system buttons。
When I press the back button, I will exit the app and return to the desktop。
May I ask how to disable the return button and customize it

Code sample

in python-for-android，i can modify PythonActivity.java

    @Override
    public void onBackPressed() {
        mWebView.evaluateJavascript("javascript:back()",new ValueCallback<String>(){	    
            @Override
            public void onReceiveValue(String s) {}
        });
        return;
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_DPAD_UP | keyCode == KeyEvent.KEYCODE_DPAD_DOWN | keyCode == KeyEvent.KEYCODE_DPAD_LEFT | keyCode == KeyEvent.KEYCODE_DPAD_RIGHT) {
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
