how to launch a fragment of an activity from another activity?
<p>I have one activity 'A' which has many buttons on it to call several corresponding fragments of another activity 'B'.</p>

<p>Activity 'B' contains a navigation drawer where i have created fragments for all the items that we have in the navigation drawer.</p>

<p>So, how do i immediately launch suppose 'fragment 1' ( i.e one of the items of the navigation drawer), inside Activity B, when Activity A calls Activity B.</p>
