open an activity from a CordovaPlugin

I have written a CordavaPlugin derived class.

public class ShowMap extends CordovaPlugin {

@Override
public boolean execute(String action, JSONArray args,
        CallbackContext callbackContext) throws JSONException {

    if (action.compareTo("showMap") == 0)
    {
        String message = args.getString(0); 
        this.echo(message, callbackContext);

        Intent i = new Intent();


        return true;
    }

    return false;
}

private void echo(String message, CallbackContext callbackContext) {
    if (message != null && message.length() > 0) { 
        callbackContext.success(message);
    } else {
        callbackContext.error("Expected one non-empty string argument.");
    }
}

}

I want from this class to open a new activity. How do I get access to the original context of the phonegap based class?

Post now in 2017, because it's the top-ranked google search result for "cordova plugin activity" and top-voted answer, along with Cordova plugin guide are both missing the following critical information, that took me many hours to figure out... the parent attrib of config-file and the specific code:

Added to plugin.xml, customized according to your needs:

<!-- separate config-file here targeting AndroidManifest with parent NOT equal to /* -->
<config-file target="AndroidManifest.xml"
    parent="/manifest/application">
    <activity
        android:name=com.custompackage.MyCustomActivity">
    </activity>         
</config-file>

Updating launching code with above package & activity:

Context context=this.cordova.getActivity().getApplicationContext();
//or Context context=cordova.getActivity().getApplicationContext();
Intent intent=new Intent(context, com.custompackage.MyCustomActivity.class);

context.startActivity(intent);
//or cordova.getActivity().startActivity(intent);

See this example.

Firstly you need to declare your custom plugin in config.xml. You can found this file in res > xml folder.

<feature name="CustomPlugin">
      <param name="android-package" value="com.Phonegap.CustomPlugin" />
</feature>

Then you need to implement plugin by using Java- code

public class CustomPlugin extends CordovaPlugin {

    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext)
            throws JSONException {

        if (action.equals("sayHello")){
            try {
                String responseText = "Hello world, " + args.getString(0);
                callbackContext.success(responseText);
            } catch (JSONException e){
                callbackContext.error("Failed to parse parameters");
            }
            return true;
        }

        return false;
    }
}

Finally we calling a plugin from javascript

function initial(){
    var name = $("#NameInput").val();
    cordova.exec(sayHelloSuccess, sayHelloFailure, "CustomPlugin", "sayHello", [name]);
}

function sayHelloSuccess(data){
    alert("OK: " + data);
}

function sayHelloFailure(data){
    alert("FAIL: " + data);
}

I used implicit intent go get this functionality working 

  Intent i = new Intent("ACTION_PLAY_VIDEO");
 this.cordova.startActivityForResult((CordovaPlugin) this,i, 0);

don't forget to put intent filter in your target activity in manifest file

<activity android:name="VideoPlayerActivity" >
       <intent-filter>
            <action android:name="ACTION_PLAY_VIDEO" />


            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>

  1. Register your activity in the AndroidManifest file
  2. In your plugin you should have the code like this, notice no "callback.success()" is called
  3. Run the action in ui thread and not background thread.

  4. enjoy 

    if (action.equals("myaction")) {
    cordova.getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
            Context context = cordova.getActivity()
                    .getApplicationContext();
            Intent intent = new Intent(context, MyNewActivityGap.class);
            cordova.getActivity().startActivity(intent);
        }
    });

    return true;
}

Context context =  cordova.getActivity().getApplicationContext();
Intent intent = new Intent(context,Next_Activity.class);

cordova.startActivityForResult(this, intent,0);

try as:

    Context context=this.cordova.getActivity().getApplicationContext();
    //or Context context=cordova.getActivity().getApplicationContext();
    Intent intent=new Intent(context,Next_Activity.class);

    context.startActivity(intent);
    //or cordova.getActivity().startActivity(intent);

and make sure you have registered Next Activity in AndroidManifest.xml
