Use the SendAction API: https://www.ibm.com/support/knowledgecenter/SSHS8R_7.1.0/com.ibm.worklight.dev.doc/devref/t_sending_actions_js_to_native.html

You can call right in wlCommonInit which is called once the MobileFirst SDK has been fully initialized.

Use this API

main.js


var param = {
              name: "hello"   //parameter pass to activity
            };
WL.NativePage.show("com.xyz.TestActivity", function(data){
        alert("data from activity "+data);
    }, param);

Make TestActivity in pkg com.xyz

TestActivity.java

package com.xyz;
import android.util.Log;
import android.annotation.TargetApi;
import android.app.Activity;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;

public class TestActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test);

    String l_name = getIntent().getStringExtra("name");  // way to take   param from js file

    Intent in = new Intent();
    in.putExtra("test", "hello success");  // return data to js from activity
    setResult(RESULT_OK, in);
    finish();
}

}

  AndroidManifest.xml

 <activity android:name=".TestActivity"></activity>

Thanks! was great help, :).. now i need to call my html page from the native activity, guess WL client is used but not sure how? – Samra Jul 04 '16 at 03:53
May be I can explain some more, I have implemented OnActionReceived function in my JS and called it on a listitem click from my native code.WL.getInstance().sendActionToJS("LoadPageReceiver"); Here, WL.getinstance gives java.state.illegalstateexception – Samra Jul 04 '16 at 05:08

implement "WLActionReceiver" in your activity and it will work. – Praj Jul 05 '16 at 12:51

So here is what I did,

Inherited CordovaActivity class instead of Activity class and implemented WLInitWebFrameworkListener. In onInitWebFrameworkComplete event added:

super.loadUrl(WL.getInstance().getMainHtmlFilePath());

Under Oncreate() method added

WL.createInstance(this);
WL.getInstance().initializeWebFramework(getApplicationContext(), this);

and now my SendActionAPI works
