question about webView

Hello, I am in Russia, and since we have not extended corona SDK no Russian support, so I apologize in advance for my English.

I have a few questions:

  1. Are there any examples of how to make the authorization in the application through the web server (PHP), I did a webmaster, but would like to learn how to program for android.

  2. Is it possible to remove webView functions increase and decrease buttons, and removed altogether increase, so that the user did not understand what he sees html code.

Thank U!
