tap/click on search button on softkeyboard

1. driver.sendKeyEvent(84);
   Appium says it successfully sent in the command but 'search' does not get tapped. Cursor remains in text box and results do not filter.

2. HashMap swipeObject = new HashMap();
   swipeObject.put("keycode", 84);
   ((JavascriptExecutor ) driver).executeScript("mobile: keyevent", swipeObject);
   Appium says not yet implemented.

3. JavascriptExecutor jse = (JavascriptExecutor) driver1; jse.executeScript("UIATarget.localTarget().frontMostApp().keyboard().buttons()['Done'].tap();");
   Appium says not yet implemented.

4. driver.sendKeyEvent(AndroidKeyCode.ENTER, AndroidKeyMetastate.META_FUNCTION_ON);
   Appium says it successfully sent in the command but 'search' does not get tapped. Cursor remains in text box and results do not filter.

5. driver.sendKeyEvent(AndroidKeyCode.ENTER);
   Nothing happens
