Answer 1

You can use below code to check whether network connection is available or not.

public class NetworkConnection {
    public Context context;

    public NetworkConnection(Context applicationContext) {
        this.context=applicationContext;
    }

    public boolean isOnline() {
        ConnectivityManager cm = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = cm.getActiveNetworkInfo();
        if (netInfo != null && netInfo.isConnectedOrConnecting()) {
            return true;
        }
        return false;
    }
}

public class MainActivity extends AppCompatActivity {
    NetworkConnection nt_check;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        nt_check=new NetworkConnection(context);
        if(nt_check.isOnline()) {
            // do logic
        } else {
            // show message network is not available.
        }
    }
}
