Hide the Webview address bar

Question

How I needed to develop an app like WebApp, followed a tutorial and succeeded (the tutorial used Android Studio IDE 1.0.2). The application works satisfactorily, however there is a detail that I know that this type of application should not present: The Address bar above all pages of the site (image). I used the latest version of Android Studio (1.4.1). Could someone help me solve this problem? Would there be a way for the bar not to appear during the display of the site? I have searched several places on the Web but the information is always from previous versions and the project structure does not equal that of 1.4.1. Thanks in advance for the help!!!

Answer 1

Add this to disable the address bar:

WebView.setWebViewClient(new WebViewClient());

Answer 2

Try to insert into Androidmanifest.xml, within the Activity where he owns the webview:

<activity
.
.
.
android:theme="android:style/Theme.Light.NoTitleBar.Fullscreen"
     ou
android:theme="@android:style/Theme.NoTitleBar"
>
</activity>
