title: Sendkeys fails on android appium driver
body: <p><strong>I am using appium to automate android application. In that, unable to perform sendkeys() on text fields for the below case:
  Clicking on Add Customer option. A new page is opened. I am trying to enter values in the text fields. I was able to find the text fields on the page using xpath. And I was able to click at the text fields. But When I execute sendkeys(), it is failing.
