 /**
- * <p>A View that displays web pages. This class is the basis upon which you
- * can roll your own web browser or simply display some online content within your Activity.
- * It uses the WebKit rendering engine to display
- * web pages and includes methods to navigate forward and backward
- * through a history, zoom in and out, perform text searches and more.
- *
- * <p>Note that, in order for your Activity to access the Internet and load web pages
- * in a WebView, you must add the {@code INTERNET} permissions to your
- * Android Manifest file:
- *
- * <pre>
- * {@code <uses-permission android:name="android.permission.INTERNET" />}
- * </pre>
- *
- * <p>This must be a child of the <a
- * href="{@docRoot}guide/topics/manifest/manifest-element.html">{@code <manifest>}</a>
- * element.
- *
- * <p>For more information, read
- * <a href="{@docRoot}guide/webapps/webview.html">Building Web Apps in WebView</a>.
+ * A View that displays web pages.
  *
  * <h3>Basic usage</h3>
  *
- * <p>By default, a WebView provides no browser-like widgets, does not
- * enable JavaScript and web page errors are ignored. If your goal is only
- * to display some HTML as a part of your UI, this is probably fine;
- * the user won't need to interact with the web page beyond reading
- * it, and the web page won't need to interact with the user. If you
- * actually want a full-blown web browser, then you probably want to
- * invoke the Browser application with a URL Intent rather than show it
- * with a WebView. For example:
- * <pre>
- * Uri uri = Uri.parse("https://www.example.com");
- * Intent intent = new Intent(Intent.ACTION_VIEW, uri);
- * startActivity(intent);
- * </pre>
- * <p>See {@link android.content.Intent} for more information.
  *
- * <p>To provide a WebView in your own Activity, include a {@code <WebView>} in your layout,
- * or set the entire Activity window as a WebView during {@link
- * android.app.Activity#onCreate(Bundle) onCreate()}:
+ * <p>In most cases, we recommend using a standard web browser, like Chrome, to deliver
+ * content to the user. To learn more about web browsers, read the guide on
+ * <a href="/guide/components/intents-common#Browser">
+ * invoking a browser with an intent</a>.
  *
- * <pre class="prettyprint">
- * WebView webview = new WebView(this);
- * setContentView(webview);
- * </pre>
+ * <p>WebView objects allow you to display web content as part of your activity layout, but
+ * lack some of the features of fully-developed browsers. A WebView is useful when
+ * you need increased control over the UI and advanced configuration options that will allow
+ * you to embed web pages in a specially-designed environment for your app.
  *
- * <p>Then load the desired web page:
- *
- * <pre>
- * // Simplest usage: note that an exception will NOT be thrown
- * // if there is an error loading this page (see below).
- * webview.loadUrl("https://example.com/");
- *
- * // OR, you can also load from an HTML string:
- * String summary = "&lt;html>&lt;body>You scored &lt;b>192&lt;/b> points.&lt;/body>&lt;/html>";
- * webview.loadData(summary, "text/html", null);
- * // ... although note that there are restrictions on what this HTML can do.
- * // See {@link #loadData(String,String,String)} and {@link
- * #loadDataWithBaseURL(String,String,String,String,String)} for more info.
- * // Also see {@link #loadData(String,String,String)} for information on encoding special
- * // characters.
- * </pre>
- *
- * <p>A WebView has several customization points where you can add your
- * own behavior. These are:
- *
- * <ul>
- *   <li>Creating and setting a {@link android.webkit.WebChromeClient} subclass.
- *       This class is called when something that might impact a
- *       browser UI happens, for instance, progress updates and
- *       JavaScript alerts are sent here (see <a
- * href="{@docRoot}guide/developing/debug-tasks.html#DebuggingWebPages">Debugging Tasks</a>).
- *   </li>
- *   <li>Creating and setting a {@link android.webkit.WebViewClient} subclass.
- *       It will be called when things happen that impact the
- *       rendering of the content, eg, errors or form submissions. You
- *       can also intercept URL loading here (via {@link
- * android.webkit.WebViewClient#shouldOverrideUrlLoading(WebView,String)
- * shouldOverrideUrlLoading()}).</li>
- *   <li>Modifying the {@link android.webkit.WebSettings}, such as
- * enabling JavaScript with {@link android.webkit.WebSettings#setJavaScriptEnabled(boolean)
- * setJavaScriptEnabled()}. </li>
- *   <li>Injecting Java objects into the WebView using the
- *       {@link android.webkit.WebView#addJavascriptInterface} method. This
- *       method allows you to inject Java objects into a page's JavaScript
- *       context, so that they can be accessed by JavaScript in the page.</li>
- * </ul>
- *
- * <p>Here's a more complicated example, showing error handling,
- *    settings, and progress notification:
- *
- * <pre class="prettyprint">
- * // Let's display the progress in the activity title bar, like the
- * // browser app does.
- * getWindow().requestFeature(Window.FEATURE_PROGRESS);
- *
- * webview.getSettings().setJavaScriptEnabled(true);
- *
- * final Activity activity = this;
- * webview.setWebChromeClient(new WebChromeClient() {
- *   public void onProgressChanged(WebView view, int progress) {
- *     // Activities and WebViews measure progress with different scales.
- *     // The progress meter will automatically disappear when we reach 100%
- *     activity.setProgress(progress * 1000);
- *   }
- * });
- * webview.setWebViewClient(new WebViewClient() {
- *   public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
- *     Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
- *   }
- * });
- *
- * webview.loadUrl("https://developer.android.com/");
- * </pre>
- *
- * <h3>Zoom</h3>
- *
- * <p>To enable the built-in zoom, set
- * {@link #getSettings() WebSettings}.{@link WebSettings#setBuiltInZoomControls(boolean)}
- * (introduced in API level {@link android.os.Build.VERSION_CODES#CUPCAKE}).
- *
- * <p class="note"><b>Note:</b> Using zoom if either the height or width is set to
- * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} may lead to undefined behavior
- * and should be avoided.
- *
- * <h3>Cookie and window management</h3>
- *
- * <p>For obvious security reasons, your application has its own
- * cache, cookie store etc.&mdash;it does not share the Browser
- * application's data.
- *
- * <p>By default, requests by the HTML to open new windows are
- * ignored. This is {@code true} whether they be opened by JavaScript or by
- * the target attribute on a link. You can customize your
- * {@link WebChromeClient} to provide your own behavior for opening multiple windows,
- * and render them in whatever manner you want.
- *
- * <p>The standard behavior for an Activity is to be destroyed and
- * recreated when the device orientation or any other configuration changes. This will cause
- * the WebView to reload the current page. If you don't want that, you
- * can set your Activity to handle the {@code orientation} and {@code keyboardHidden}
- * changes, and then just leave the WebView alone. It'll automatically
- * re-orient itself as appropriate. Read <a
- * href="{@docRoot}guide/topics/resources/runtime-changes.html">Handling Runtime Changes</a> for
- * more information about how to handle configuration changes during runtime.
- *
- *
- * <h3>Building web pages to support different screen densities</h3>
- *
- * <p>The screen density of a device is based on the screen resolution. A screen with low density
- * has fewer available pixels per inch, where a screen with high density
- * has more &mdash; sometimes significantly more &mdash; pixels per inch. The density of a
- * screen is important because, other things being equal, a UI element (such as a button) whose
- * height and width are defined in terms of screen pixels will appear larger on the lower density
- * screen and smaller on the higher density screen.
- * For simplicity, Android collapses all actual screen densities into three generalized densities:
- * high, medium, and low.
- * <p>By default, WebView scales a web page so that it is drawn at a size that matches the default
- * appearance on a medium density screen. So, it applies 1.5x scaling on a high density screen
- * (because its pixels are smaller) and 0.75x scaling on a low density screen (because its pixels
- * are bigger).
- * Starting with API level {@link android.os.Build.VERSION_CODES#ECLAIR}, WebView supports DOM, CSS,
- * and meta tag features to help you (as a web developer) target screens with different screen
- * densities.
- * <p>Here's a summary of the features you can use to handle different screen densities:
- * <ul>
- * <li>The {@code window.devicePixelRatio} DOM property. The value of this property specifies the
- * default scaling factor used for the current device. For example, if the value of {@code
- * window.devicePixelRatio} is "1.0", then the device is considered a medium density (mdpi) device
- * and default scaling is not applied to the web page; if the value is "1.5", then the device is
- * considered a high density device (hdpi) and the page content is scaled 1.5x; if the
- * value is "0.75", then the device is considered a low density device (ldpi) and the content is
- * scaled 0.75x.</li>
- * <li>The {@code -webkit-device-pixel-ratio} CSS media query. Use this to specify the screen
- * densities for which this style sheet is to be used. The corresponding value should be either
- * "0.75", "1", or "1.5", to indicate that the styles are for devices with low density, medium
- * density, or high density screens, respectively. For example:
- * <pre>
- * &lt;link rel="stylesheet" media="screen and (-webkit-device-pixel-ratio:1.5)" href="hdpi.css" /&gt;</pre>
- * <p>The {@code hdpi.css} stylesheet is only used for devices with a screen pixel ratio of 1.5,
- * which is the high density pixel ratio.
- * </li>
- * </ul>
- *
- * <h3>HTML5 Video support</h3>
- *
- * <p>In order to support inline HTML5 video in your application you need to have hardware
- * acceleration turned on.
- *
- * <h3>Full screen support</h3>
- *
- * <p>In order to support full screen &mdash; for video or other HTML content &mdash; you need to set a
- * {@link android.webkit.WebChromeClient} and implement both
- * {@link WebChromeClient#onShowCustomView(View, WebChromeClient.CustomViewCallback)}
- * and {@link WebChromeClient#onHideCustomView()}. If the implementation of either of these two methods is
- * missing then the web contents will not be allowed to enter full screen. Optionally you can implement
- * {@link WebChromeClient#getVideoLoadingProgressView()} to customize the View displayed whilst a video
- * is loading.
- *
- * <h3>HTML5 Geolocation API support</h3>
- *
- * <p>For applications targeting Android N and later releases
- * (API level > {@link android.os.Build.VERSION_CODES#M}) the geolocation api is only supported on
- * secure origins such as https. For such applications requests to geolocation api on non-secure
- * origins are automatically denied without invoking the corresponding
- * {@link WebChromeClient#onGeolocationPermissionsShowPrompt(String, GeolocationPermissions.Callback)}
- * method.
- *
- * <h3>Layout size</h3>
- * <p>
- * It is recommended to set the WebView layout height to a fixed value or to
- * {@link android.view.ViewGroup.LayoutParams#MATCH_PARENT} instead of using
- * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT}.
- * When using {@link android.view.ViewGroup.LayoutParams#MATCH_PARENT}
- * for the height none of the WebView's parents should use a
- * {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} layout height since that could result in
- * incorrect sizing of the views.
- *
- * <p>Setting the WebView's height to {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT}
- * enables the following behaviors:
- * <ul>
- * <li>The HTML body layout height is set to a fixed value. This means that elements with a height
- * relative to the HTML body may not be sized correctly. </li>
- * <li>For applications targeting {@link android.os.Build.VERSION_CODES#KITKAT} and earlier SDKs the
- * HTML viewport meta tag will be ignored in order to preserve backwards compatibility. </li>
- * </ul>
- *
- * <p>
- * Using a layout width of {@link android.view.ViewGroup.LayoutParams#WRAP_CONTENT} is not
- * supported. If such a width is used the WebView will attempt to use the width of the parent
- * instead.
- *
- * <h3>Metrics</h3>
- *
- * <p>
- * WebView may upload anonymous diagnostic data to Google when the user has consented. This data
- * helps Google improve WebView. Data is collected on a per-app basis for each app which has
- * instantiated a WebView. An individual app can opt out of this feature by putting the following
- * tag in its manifest's {@code <application>} element:
- * <pre>
- * &lt;manifest&gt;
- *     &lt;application&gt;
- *         ...
- *         &lt;meta-data android:name=&quot;android.webkit.WebView.MetricsOptOut&quot;
- *             android:value=&quot;true&quot; /&gt;
- *     &lt;/application&gt;
- * &lt;/manifest&gt;
- * </pre>
- * <p>
- * Data will only be uploaded for a given app if the user has consented AND the app has not opted
- * out.
- *
- * <h3>Safe Browsing</h3>
- *
- * <p>
- * With Safe Browsing, WebView will block malicious URLs and present a warning UI to the user to
- * allow them to navigate back safely or proceed to the malicious page.
- * <p>
- * Safe Browsing is enabled by default on devices which support it. If your app needs to disable
- * Safe Browsing for all WebViews, it can do so in the manifest's {@code <application>} element:
- * <p>
- * <pre>
- * &lt;manifest&gt;
- *     &lt;application&gt;
- *         ...
- *         &lt;meta-data android:name=&quot;android.webkit.WebView.EnableSafeBrowsing&quot;
- *             android:value=&quot;false&quot; /&gt;
- *     &lt;/application&gt;
- * &lt;/manifest&gt;
- * </pre>
- *
- * <p>
- * Otherwise, see {@link WebSettings#setSafeBrowsingEnabled}.
+ * <p>To learn more about WebView and alternatives for serving web content, read the
+ * documentation on
+ * <a href="/guide/webapps/">
+ * Web-based content</a>.
