|
||
|
|
* <h3>Basic usage</h3>
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* <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>.
|
||
|
|
*
|
||
|
|
* <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>To learn more about WebView and alternatives for serving web content, read the
|
||
|
|
* documentation on
|
||
|
|
* <a href="/guide/webapps/">
|
||
|
|
* Web-based content</a>.

|
* <li> This method can be used to allow JavaScript to control the host
|
||
|
|
* application. This is a powerful feature, but also presents a security
|
||
|
|
* risk for apps targeting {@link android.os.Build.VERSION_CODES#JELLY_BEAN} or earlier.
|
||
|
|
* Apps that target a version later than {@link android.os.Build.VERSION_CODES#JELLY_BEAN}
|
||
|
|
* are still vulnerable if the app runs on a device running Android earlier than 4.2.
|
||
|
|
* The most secure way to use this method is to target {@link android.os.Build.VERSION_CODES#JELLY_BEAN_MR1}
|
||
|
|
* and to ensure the method is called only when running on Android 4.2 or later.
|
||
|
|
* With these older versions, JavaScript could use reflection to access an
|
||
|
|
* injected object's public fields. Use of this method in a WebView
|
||
|
|
* containing untrusted content could allow an attacker to manipulate the
|
||
|
|
* host application in unintended ways, executing Java code with the
|
||
|
|
* permissions of the host application. Use extreme care when using this
|
||
|
|
* method in a WebView which could contain untrusted content.</li>
|
||
|
|
* <li> JavaScript interacts with Java object on a private, background
|
||
|
|
* thread of this WebView. Care is therefore required to maintain thread
|
||
|
|
* safety.
|
||
|
|
* </li>
|
||
|
|
* <li> Because the object is exposed to all the frames, any frame could
|
||
|
|
* obtain the object name and call methods on it. There is no way to tell the
|
||
|
|
* calling frame's origin from the app side, so the app must not assume that
|
||
|
|
* the caller is trustworthy unless the app can guarantee that no third party
|
||
|
|
* content is ever loaded into the WebView even inside an iframe.</li>
|
||
|
|
* <li> The Java object's fields are not accessible.</li>
|
||
|
|
* <li> For applications targeted to API level {@link android.os.Build.VERSION_CODES#LOLLIPOP}
|

/**
|
||
|
|
* {@inheritDoc}
|
||
|
|
*
|
||
|
|
* <p>The {@link ViewStructure} traditionally represents a {@link View}, while for web pages
|
||
|
|
* it represent HTML nodes. Hence, it's necessary to "map" the HTML properties in a way that is
|
||
|
|
* understood by the {@link android.service.autofill.AutofillService} implementations:
|
||
|
|
*
|
||
|
|
* <ol>
|
||
|
|
* <li>Only the HTML nodes inside a {@code FORM} are generated.
|
||
|
|
* <li>The source of the HTML is set using {@link ViewStructure#setWebDomain(String)} in the
|
||
|
|
* node representing the WebView.
|
||
|
|
* <li>If a web page has multiple {@code FORM}s, only the data for the current form is
|
||
|
|
* represented—if the user taps a field from another form, then the current autofill
|
||
|
|
* context is canceled (by calling {@link android.view.autofill.AutofillManager#cancel()} and
|
||
|
|
* a new context is created for that {@code FORM}.
|
||
|
|
* <li>Similarly, if the page has {@code IFRAME} nodes, they are not initially represented in
|
||
|
|
* the view structure until the user taps a field from a {@code FORM} inside the
|
||
|
|
* {@code IFRAME}, in which case it would be treated the same way as multiple forms described
|
||
|
|
* above, except that the {@link ViewStructure#setWebDomain(String) web domain} of the
|
||
|
|
* {@code FORM} contains the {@code src} attribute from the {@code IFRAME} node.
|
||
|
|
* <li>The W3C autofill field ({@code autocomplete} tag attribute) maps to
|
||
|
|
* {@link ViewStructure#setAutofillHints(String[])}.
|
||
|
|
* <li>If the view is editable, the {@link ViewStructure#setAutofillType(int)} and
|
||
|
|
* {@link ViewStructure#setAutofillValue(AutofillValue)} must be set.
|
||
|
|
* <li>The {@code placeholder} attribute maps to {@link ViewStructure#setHint(CharSequence)}.
|
||
|
|
* <li>Other HTML attributes can be represented through
|
||
|
|
* {@link ViewStructure#setHtmlInfo(android.view.ViewStructure.HtmlInfo)}.
|
||
|
|
* </ol>
|
||
|
|
*
|
||
|
|
* <p>If the WebView implementation can determine that the value of a field was set statically
|
||
|
|
* (for example, not through Javascript), it should also call
|
||
|
|
* {@code structure.setDataIsSensitive(false)}.
|
||
|
|
*
|
||
|
|
* <p>For example, an HTML form with 2 fields for username and password:
|
||
|
|
*
|
||
|
|
* <pre class="prettyprint">
|
||
|
|
* <label>Username:</label>
|
||
|
|
* <input type="text" name="username" id="user" value="Type your username" autocomplete="username" placeholder="Email or username">
|
||
|
|
* <label>Password:</label>
|
||
|
|
* <input type="password" name="password" id="pass" autocomplete="current-password" placeholder="Password">
|
||
|
|
* </pre>
|
||
|
|
*
|
||
|
|
* <p>Would map to:
|
||
|
|
*
|
||
|
|
* <pre class="prettyprint">
|
||
|
|
* int index = structure.addChildCount(2);
|
||
|
|
* ViewStructure username = structure.newChild(index);
|
||
|
|
* username.setAutofillId(structure.getAutofillId(), 1); // id 1 - first child
|
||
|
|
* username.setAutofillHints("username");
|
||
|
|
* username.setHtmlInfo(username.newHtmlInfoBuilder("input")
|
||
|
|
* .addAttribute("type", "text")
|
||
|
|
* .addAttribute("name", "username")
|
||
|
|
* .addAttribute("label", "Username:")
|
||
|
|
* .build());
|
||
|
|
* username.setHint("Email or username");
|
||
|
|
* username.setAutofillType(View.AUTOFILL_TYPE_TEXT);
|
||
|
|
* username.setAutofillValue(AutofillValue.forText("Type your username"));
|
||
|
|
* // Value of the field is not sensitive because it was created statically and not changed.
|
||
|
|
* username.setDataIsSensitive(false);
|
||
|
|
*
|
||
|
|
* ViewStructure password = structure.newChild(index + 1);
|
||
|
|
* username.setAutofillId(structure, 2); // id 2 - second child
|
||
|
|
* password.setAutofillHints("current-password");
|
||
|
|
* password.setHtmlInfo(password.newHtmlInfoBuilder("input")
|
||
|
|
* .addAttribute("type", "password")
|
||
|
|
* .addAttribute("name", "password")
|
||
|
|
* .addAttribute("label", "Password:")
|
||
|
|
* .build());
|
||
|
|
* password.setHint("Password");
|
||
|
|
* password.setAutofillType(View.AUTOFILL_TYPE_TEXT);
