About proxySettingsChanged, is kind like a callback. How about setProxy ?

The usage of proxy in video/audio is different from other web resources. For video/audio: Crosswalk for android will call android system services named android.widget.MediaPlayer to handle video/audio, unfortunately MediaPlayer API doesn't provide a ready-to-use method for proxy setting at the moment, but there is a possible workaround in http://stackoverflow.com/questions/10627278/how-to-set-proxy-on-mediaplayer that a local server socket need to be setup to listen the request from MediaPlayer, download the media contents with httpClient and feed those streams to MediaPlayer. So I intent to implement the new API in XWalkResourceClient to intercept normal playing video/audio @Override /** @param View The XWalkViewInternal that is initiating the callback @param mediaPalyer the android system services @param context the context to use when resolving the Uri @param uri the Content URI of data you want to play @param header the headers to be sent together with the request for the data Note that the cross domain redirection is allowed by default @return True if want to play itself, otherwise return false */ public boolean shouldOverrideResourceLoading(XWalkView view, MediaPlayer mediaPlayer, Context context, Uri uri, Map<String, String> headers) { } Related feature: XWALK-6770 For other web resources such as images, text resources: Crosswalk for android will update proxy when a PROXY_CHANGE intent is received, but it's need system permission to send the broadcast, there is also a workaround with reflecting the incompatible api in http://stackoverflow.com/questions/19979578/android-webview-set-proxy-programatically-kitkat , but it's too complex to maintain those codes, So I intent to implement the new API in XWalkView to set proxy for images/text resources /** @param host proxy host @param port proxy port @param pacUrl the PAC script at the specified URL. @param exclusionList Hosts to exclude using the proxy on connections for. These hosts can use wildcards such as *.example.com. */ public void proxySettingsChanged(String host, int port, String pacUrl, String[] exclusionList) Related feature: XWALK-6769 Target release: Crosswalk-20 Implementation details: shouldOverrideResourceLoading API: Chromium upstream code need to add a new param in net/proxy/proxy_config_service_android.cc public static class ResourceLoadingFilter { public boolean shouldOverrideResourceLoading( - MediaPlayer mediaPlayer, Context context, Uri uri) { + MediaPlayer mediaPlayer, Context context, Uri uri, Map<String, String> headers) { return false; } } Then XWalk repo will export the api to XWalkResourceClient. proxySettingsChanged API: Chromium upstream code need to add an new API in net/proxy/proxy_config_service_android.cc +void ProxyConfigServiceAndroid::ProxySettingsChangedTo( + const std::string& host, + int port, + const std::string& pac_url, + const std::vector<std::string>& exclusion_list) { + delegate_->ProxySettingsChangedTo(host, port, pac_url, exclusion_list); +} Then XWalk repo will export the api to XWalkView.
