You can use ContactsContract.Profile

    String name  = "";
    Cursor c = getApplication().getContentResolver().query(ContactsContract.Profile.CONTENT_URI, null, null, null, null); 
    if(c.moveToFirst()) {
     name = c.getString(c.getColumnIndex("display_name"));
     c.close();
   }

You need permissions too

<uses-permission android:name="android.permission.READ_PROFILE"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
