crash - Checking if a user is connected to the network in android -

in main activity have

 if (isnetworkavailable() == true) {         log.i("testing", "available");      } else {         log.i("test", "unaivalibale");     } 

then below have method

  private boolean isnetworkavailable() {     connectivitymanager connectivitymanager             = (connectivitymanager) getsystemservice(context.connectivity_service);     networkinfo activenetworkinfo = connectivitymanager.getactivenetworkinfo();     return activenetworkinfo != null && activenetworkinfo.isconnected(); } 

i have set

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

in manifest , yet when run tha application stops, killing application wrong

make class , add method properly:

public class connectivitystatus extends contextwrapper{ public connectivitystatus(context base) {     super(base); }  public static boolean isconnected(context context){      connectivitymanager manager = (connectivitymanager) context.getsystemservice(context.connectivity_service);     networkinfo connection = manager.getactivenetworkinfo();     if (connection != null && connection.isconnectedorconnecting()){         return true;     }     return false;  } } 

get status, in activity using as:

if(!connectivitystatus.isconnected(your_class_name.this)){             //not connected }else {             //connected }
