I know how to check for internet connectivity when my app is open using activity. But how to check for connectivity in service when my app is not running?

You might need to use broadcast receiver. You will continuously receive updates in connectivity.(Connected/Disconnected)

Example:

Manifest:

Permissions:

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

<receiver android:name=".ConnectivityChangeReceiver" >
    <intent-filter>
        <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
    </intent-filter>
</receiver>

Create receiver class:

public class ConnectivityChangeReceiver extends BroadcastReceiver {


    @Override
    public void onReceive(Context context, Intent intent) {

        // Explicitly specify that which service class will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                YourService.class.getName());
        intent.putExtra("isNetworkConnected",isConnected(context));
        startService(context, (intent.setComponent(comp)));
    }

 public  boolean isConnected(Context context) {
           ConnectivityManager connectivityManager = ((ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE));
           NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
           return networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected();
   }

}

Your service class:

class YourService extends IntentService{

    @Override
    protected void onHandleIntent(Intent intent) {
      Bundle extras = intent.getExtras();
      boolean isNetworkConnected = extras.getBoolean("isNetworkConnected");
      // your code

   }

}
