android - Getting application context into fragment, ViewPager -


i'm writing simple app swipe view using viewpager , fullscreen fragments. in 1 of fragments want check internet connection status before displaying data can't application context. i've found lot of topics on issue, none of solutions works me. using getapplication() within fragment though error "unreacheable statement".

any advice?

import android.support.v4.app.fragmentactivity; import android.support.v4.view.viewpager; import android.os.bundle;  public class mainactivity extends fragmentactivity {  viewpager viewpager;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      //setting fragment view pager     viewpager = (viewpager)findviewbyid(r.id.pager);     pageradapter pageradapter = new   pageradapter(getsupportfragmentmanager());     viewpager.setadapter(pageradapter);     } } 

activity_main.xml

<android.support.v4.view.viewpager xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent"> </android.support.v4.view.viewpager> 

first fragment

import android.support.v4.app.fragment; import android.os.bundle; import android.support.annotation.nullable; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup;  public class currentweatherfragment extends fragment {  //flaga dla statusu polaczenia z internetem boolean isinternetpresent = false;  //klasa detektora połączenia connectiondetector cd;   @nullable @override  public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view v = inflater.inflate(r.layout.currentweather, container, false);     return v;      //tworzenie klasy detektora     cd = new connectiondetector(getactivity().getapplicationcontext());      //sprawdzenie czy jest polaczenie z internetem     isinternetpresent = cd.isconnectingtointernet();     } } 

pager adapter class

import android.support.v4.app.fragment; import android.support.v4.app.fragmentmanager; import android.support.v4.app.fragmentpageradapter;  public class pageradapter extends fragmentpageradapter {  public pageradapter(fragmentmanager fm) {     super(fm); }  @override public fragment getitem(int arg0) {     switch (arg0){         case 0:             return new currentweatherfragment();         case 1:             return new forecastfragment();         default:             break;     }     return null; }  @override public int getcount() {     return 2;     } } 

in currentweatherfragment's oncreateview inflate view instantly return it.

public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view v = inflater.inflate(r.layout.currentweather, container, false);     return v;      //tworzenie klasy detektora     cd = new connectiondetector(getactivity().getapplicationcontext());      //sprawdzenie czy jest polaczenie z internetem     isinternetpresent = cd.isconnectingtointernet(); } 

move return v; end of method:

public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view v = inflater.inflate(r.layout.currentweather, container, false);      //tworzenie klasy detektora     cd = new connectiondetector(getactivity().getapplicationcontext());      //sprawdzenie czy jest polaczenie z internetem     isinternetpresent = cd.isconnectingtointernet();      return v; }
