java - Error inflating class fragment ( android.view.InflateExpection ) -

so trying incorporate google map in fragment, have followed steps mentioned on google dev docs on maps, error in inflating class fragment. went through many stacks , did mentioned in them, error persists. here's map fragment,

fragment_two.java

    package com.example.theweddingapp;  import com.google.android.gms.maps.cameraupdate; import com.google.android.gms.maps.cameraupdatefactory; import com.google.android.gms.maps.googlemap; import com.google.android.gms.maps.mapfragment; import com.google.android.gms.maps.mapview; import com.google.android.gms.maps.mapsinitializer; import com.google.android.gms.maps.onmapreadycallback; import com.google.android.gms.maps.supportmapfragment; import com.google.android.gms.maps.model.latlng; import com.google.android.gms.maps.model.markeroptions;  import android.content.context; import android.os.bundle; import android.support.v4.app.fragment; import android.support.v4.app.fragmentactivity; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup;  public class fragmenttwo extends fragment implements onmapreadycallback {      mapview mapview;     googlemap map;      public static fragment newinstance(context context) {         fragmenttwo f = new fragmenttwo();         return f;     }       public view oncreateview(layoutinflater inflater, viewgroup container,bundle savedinstancestate) {         viewgroup root = (viewgroup) inflater.inflate(r.layout.fragment_two, null);         getactivity().setcontentview(r.layout.fragment_two);         mapfragment mapfragment = (mapfragment) getactivity().getfragmentmanager().findfragmentbyid(r.id.map);             mapfragment.getmapasync(this);         return root;     }     @override     public void onmapready(googlemap map) {         map.addmarker(new markeroptions()             .position(new latlng(0, 0))             .title("marker"));     }   } 

my map xml,

fragment_two.xml

    <?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical" > <fragment android:name="com.google.android.gms.maps.supportmapfragment"     android:id="@+id/map"     android:layout_width="match_parent"     android:layout_height="match_parent"/> </relativelayout> 

here's manifest

androidmanifest.xml
