title: Fill fields in webview automatically
body: <p>I have seen this question floating around the internet, but I haven't found a working solution yet. Basically, I want to load my app and press a button; the button action will then fill in a username and password in a website already loaded in the webview (or wait for onPageFinished). Finally, the submit button on the login page will be activated. </p>
  
  <p>From what I understand this can be done by doing a java injection with the loadUrl(javascript), but I don't know what the java commands would be to fill in the fields. The same question was asked for <a href="https://stackoverflow.com/questions/7729473/can-i-use-username-and-password-information-from-uitextfields-to-log-onto-a-webs">iOS</a>, but the commands are slightly different.</p>
  
  <p>Is it possible to do what I am asking with javascript in a webivew, or do I have to do a http-post without a webview like <a href="https://stackoverflow.com/questions/7186784/android-httppost-login-action">this</a> or <a href="https://stackoverflow.com/questions/6960909/how-to-autofill-gmail-form-from-a-webview-with-basicnamevaluepair">this</a>?</p>
  
  <p>Thank you so much for any help you can give!</p>
