you can either add parent activity have deep linked in manifest, or can add state when starting activity.

manifest:

<application ... > ... <!-- main/home activity (it has no parent activity) --> <activity     android:name="com.example.myfirstapp.mainactivity" ...>     ... </activity> <!-- child of main activity --> <activity     android:name="com.example.myfirstapp.displaymessageactivity"     android:label="@string/title_activity_display_message"     android:parentactivityname="com.example.myfirstapp.mainactivity" >     <!-- meta-data element needed versions lower 4.1 -->     <meta-data         android:name="android.support.parent_activity"         android:value="com.example.myfirstapp.mainactivity" /> </activity> 

java:

// intent activity open when user selects notification intent detailsintent = new intent(this, detailsactivity.class);  // use taskstackbuilder build stack , pendingintent pendingintent pendingintent =         taskstackbuilder.create(this)                         // add of detailsactivity's parents stack,                         // followed detailsactivity                         .addnextintentwithparentstack(upintent)                         .getpendingintent(0, pendingintent.flag_update_current);  notificationcompat.builder builder = new notificationcompat.builder(this); builder.setcontentintent(pendingintent);
