XPCOM support in Android webkit browser?

Does the Android WebKit supports the XPCOM framework or NPRuntime API`s as like Firefox? How to implement JavaScript in the Android WebKit plug-in?

Update: I am writing a media player plug-in for the Android WebKit browser and my plug-in needs to get the command from the web page through JavaScript (some actions like play/pause/stop/resize are issued as JavaScript commands from the browser). My plug-in is written in native C code. Are there any examples or sample plug-in available for JavaScript communication?

+2 A:

WebKit doesn't support XPCOM, as WebKit is entirely separate from the Mozilla stack.

When you say you want to "implement Javascript", what do you mean?
The built-in Android browser already supports the execution of Javascript.

Android's WebKit doesn't support XPCOM, nor does it support NPAPI and npruntime. Not sure how you're planning to write a browser plugin, but it's not going to be possible with the Android SDK.

Does it mean ,JavaScript communication between the plug-in and browser is not possible ? or Is there any other way to do this Js communication?.My plugin is in native C code.

Plug-ins in general aren't supported in the Android SDK. How are you writing a browser plugin?

developing based on the available Sample plug-in (mydroid/development)/samples/BrowserPlugin)

Well don't I feel silly :-) Regardless, judging by the API docs: http://d.android.com/reference/android/webkit/PluginStub.html, it seems like you get an NPAPI plugin instance. You can look into using `npruntime` for exposing a JS interface to the plugin, but I'm completely unsure about whether or not this is possible

thanks Nurik,Is there any sample available for jS plugin

The android browser supported NPAPI all the time, the mechanism changed in 2.1 though, now it looks for APKs with the intent filter "android.webkit.PLUGIN", so a plugin needs to be packaged separately.

Previously setting the plugin path on the WebView and compiling the plugin using the NDK did the trick.

Hope this helps, you will find a lot of info when googling for NPAPI and WebView or NPAPI and android.

For those that didn't notice, there is a sample plugin in the Android (eclair) source already in development/samples/BrowserPlugin

I have read many posts on the Web about NPAPI android webkit support. I could not found a clear answer...

Some say that web plugins are not supported now you say that it is supported.

Can I create a plugin without modifying android sources? Are the 2.1 and 2.2 distributions compiled with the define ANDROID_PLUGINS?

Can I use PluginStub or another class since android.webkit.Plugin and other related classes have been deprecated?

Does any sample illustrating a plugin exist?
