title: round corner google sign in button - android
body: <p>I am trying to add 'Sign in with Google' feature on my app. I am using following code to add google sign in button </p>
  
  <pre><code>&lt;com.google.android.gms.common.SignInButton
     android:id="@+id/btn_google_signin"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:layout_marginTop="24dp"
     android:background="?attr/selectableItemBackground"
     android:elevation="2dp"&gt;&lt;/com.google.android.gms.common.SignInButton&gt;
  </code></pre>
  
  <p>This is rendering a rectangular button. But i want round corner button. is there any way to customize this button with round corner?</p>
  
  <p>P.S. - I am not looking to customize the normal button. I am specifically looking Google SignInButton. Please reply if you know about that only.</p>
