- view
- WebView
The android.webkit.WebView that is requesting the
resource.
- request
- IWebResourceRequest
Object containing the details of the request.
Returns
A android.webkit.WebResourceResponse containing the
response information or null if the WebView should load the
resource itself.
- Attributes
Remarks
Notify the host application of a resource request and allow the application to return the data. If the return value is null, the WebView will continue to load the resource as usual. Otherwise, the return response and data will be used.
This callback is invoked for a variety of URL schemes (e.g., http(s):, data:, file:, etc.), not only those schemes which send requests over the network. This is not called for javascript: URLs, blob: URLs, or for assets accessed via file:///android_asset/ or file:///android_res/ URLs.
In the case of redirects, this is only called for the initial resource URL, not any subsequent redirect URLs.
<p class="note"><b>Note:</b> This method is called on a thread other than the UI thread so clients should exercise caution when accessing private data or the view system.
<p class="note"><b>Note:</b> When Safe Browsing is enabled, these URLs still undergo Safe Browsing checks. If this is undesired, you can use WebView#setSafeBrowsingWhitelist to skip Safe Browsing checks for that host or dismiss the warning in #onSafeBrowsingHit by calling SafeBrowsingResponse#proceed.
