EventListener is small library and is used for communication between classes like broadcaste signals No Need to maintain listener reference. It auto work with app lifecycle.

Prerequisites

• Android 14

Installing

Step 1:- Add it in your root build.gradle at the end of repositories:

allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

Step 2:- Add the dependency:

    dependencies {
            implementation 'com.github.prabhat1707:EventListener:1.0'
    }

Usage

SendData to Register Listener:-

EventListener.getInstance().post(modelClass, "From Fragment");

Rec callback of the sendData :

• if you want to rec your post modelclass as well as Tag in callback then pass ModelClass Type in DataWrapper ```` implement Updatable> :

@Override public void EventListenerCallback(DataWrappe objectDataWrapper) { Toast.makeText(this, objectDataWrapper.getTag(), Toast.LENGTH_SHORT).show(); text.setText(objectDataWrapper.getObject().getTest()); }

//  objectDataWrapper.getObject return your modelClass

- default is

implements Updatable

@Override public void EventListenerCallback(DataWrapper objectDataWrapper) { Toast.makeText(this, objectDataWrapper.getTag(), Toast.LENGTH_SHORT).show();

}

- register or unregister the callback according to your logic for ex-:

@Override protected void onResume() { super.onResume(); EventListener.getInstance().registerListener(this); }

@Override protected void onDestroy() { super.onDestroy(); EventListener.getInstance().unregisterListener(this); }

#### Contructor types:

1. EventListener.getInstance().post("From Fragment"); // only Tag

2. EventListener.getInstance().post(); // without Tag and data

3. EventListener.getInstance().post(modelClass, "From Fragment"); // with data also
