Hello Friends,

- In this post i am going to show how we can check "Network Reachability" in Android using simple code.

- We can use this code in our app while calling API or other network related stuffs.

STEP : 1

Add some important permissions in AndroidManifiest.xml file.

uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
uses-permission android:name="android.permission.INTERNET" />
uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

STEP : 2
Create function which checks whether internet connection is available in device or not?

public static boolean hasConnection(Context context) {
ConnectivityManager cm = (ConnectivityManager) 

                             context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();         if (activeNetwork != null) { // connected to the internet            if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {                 // connected to wifi                return true;             } else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {                 // connected to the mobile provider's data plan                return true;             }         } else return false;         return false;     } 

- Finally you can call this method before doing network related task like calling API or downloading/uploading something to server.
- If this method return true then do network operation else show network error to user.
