You can’t use Cordova feature in embedded mode.

So please confirm your project can work before using embedded crosswalk, then 
develop new feature with Crosswalk 
api<https://crosswalk-project.org/apis/embeddingapidocs_v6/index.html> in 
embedded mode.

Thanks,
Junwei.

Hi,

thanks for the response.

I'm using this layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android";
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/background_dark" >
    <org.xwalk.core.XWalkView
        android:id="@+id/OverlayView"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="#000000"
        />
    <com.craftar.CraftARCameraView
        android:id="@+id/craftar_preview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" />
</RelativeLayout>



Do you mean this example 
https://crosswalk-project.org/documentation/android/embedding_crosswalk.html ?



After I click OK in the Javascript prompts (i.e. gap: init), I get lots of 
console messages as this one:



I/chromium: [INFO:CONSOLE(1083)] "processMessage failed: invalid message: """, 
source: file:///android_asset/www/cordova.js (1083)



It seems to me that cordova bridge is not being well integrated...?



Thx

Did the found view with id changed to the xwalkView?

You can try to run the sample of embedding crosswalk in the cordova plugin.

Thanks,

Subject: [Crosswalk-help] Using Crosswalk instead of SystemWebView in a Cordova 
plugin

Hi!

I'm trying to modify an existing Cordova plugin so it launches crosswalk 
instead of SystemWebView. The WebView is launched as follows:

 cameraView = (CraftARCameraView) layout.findViewById(previewId);
 wv = (SystemWebView)layout.findViewById(fakeR.getId("id", "OverlayView"));
 cordovaInterface = new CordovaInterfaceImpl((Activity) getContext());
 loadConfig();

 cwv = new CordovaWebViewImpl(new SystemWebViewEngine(wv));
 if (!cwv.isInitialized()){
    cwv.init(cordovaInterface, pluginEntries, preferences);
 }
 cwv.handleResume(true);
 if (!TextUtils.isEmpty(loadUrl)) {
    cwv.loadUrl(CraftARPlugin.ANDROID_FILE + loadUrl);
 }

All the examples I've seen embedding crosswalk are as in 
https://crosswalk-project.org/documentation/android/embedding_crosswalk.html 
,but this doesn't work for me. I'm getting errors (Javascript prompts as in 
http://stackoverflow.com/questions/16920596/phonegap-html-app-and-various-alerts-hang-browser).
 I reckon this is due to not getting a correct integration between crosswalk 
and cordova.

My code is:

 cameraView = (CraftARCameraView) layout.findViewById(previewId);
 mXWalkView = (XWalkView) findViewById(fakeR.getId("id", "OverlayView"));
 mXWalkView.load(CraftARPlugin.ANDROID_FILE + loadUrl, null);

Any help or guidance to carry on with the research would be very appreciated.

Thanks a lot
