使用cordova-plugin-crosswalk-webview从JS调用本机Java代码

Question

I can successfully call native java code from JS in a Cordova 5.4.0 application using @JavascriptInterface. But after adding cordova-plugin-crosswalk-webview, it is not working. After searching, I have modify my code as:-

public class MainActivity extends CordovaActivity{
    @Override
    public void onCreate(Bundle savedInstanceState){
      super.onCreate(savedInstanceState);
      loadUrl("file://android_assets/www/index.html");
      ((XWalkView)appView.getEngine().getView()).addJavascriptInterface(this,"MainActivity");
    }

   @JavascriptInterface
   public void getMessage() {
        Toast.makeText(getApplicationContext(), "this is my Toast message!!!  =)",Toast.LENGTH_LONG).show();
   }

}

And calling native code from js as:

window.MainActivity.getMessage();

I also imported

import org.xwalk.core.JavascriptInterface;
import org.xwalk.core.XWalkView;

Also tried replacing

@JavascriptInterface

with

@org.xwalk.core.JavascriptInterface

Now the app even not opening. It crash. Help Plz.

Answer 1

Calling the addJavaScriptInterface() inside the onXWalkReady() instead of doing this in the onCreate() callback solved this issue to me.

PS: Method chaining is not a good practice.

Answer 2

将config.xml首选项name="android-minSdkVersion" value="16" 更新为首选项name="android-minSdkVersion" value="17并使用import org.xwalk.core.JavascriptInterface;使用cordova版本6.3.0或更新
