but not getting name, instead getting exception, sating oauthexception please suggest me asap

maybe session dont have permission friend's birthday.
can request permission below:

loginbutton authbutton = (loginbutton) view.findviewbyid(r.id.authbutton); authbutton.setfragment(this); authbutton.setreadpermissions(arrays.aslist("user_friends, read_friendlists)); 

layout file:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <com.facebook.widget.loginbutton         android:id="@+id/authbutton"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_horizontal"         android:layout_margintop="30dp"         />  </linearlayout> 

note: uses facebook sdk 3.8, can refer sample more detail.
loginbutton component of facebook sdk.
