Calling javascript function from the android activity

Question

I am using the following code in the main activity , its giving the function display() is not defined

public class cordovaExample extends DroidGap {
    Cont         


        

Answer 1

From Cordova 2.6 you can override onMessage in your CordovaActivity (DroidGap), you have to capture the message "onPageFinished", then you can call any function declared on the document:

@Override
public Object onMessage(String id, Object data) {
    if("onPageFinished".equals(id)) {
        sendJavascript("display('abc');");
    }
    return super.onMessage(id, data);
}

And in the HTML:

Other option is to call it in the onResume() function of the CordovaActivity:

@Override
public void onResume() {
    super.onResume();
    sendJavascript("display('abc');");
}
