        android:weightSum="2"
        android:layout_marginTop="50dp">

    <Button
        android:id="@+id/notifyBtn"

</LinearLayout>

In this MainActivity.java we have Declared our Push Notification without firebase.

Notification.Builder builder = new Notification.Builder(MainActivity.this);

And made a notification screen such that user entered text will get displayed as a Push Notification.

No Additional Permissions required as this is local data based Push Notification but when you are doing with server based push notifications you will require Internet Permission.
