Android Turn ON wifi programmatically

Android Turn ON wifi  programmatically

Coding for Enable WIFI programmatically.

Activity.class

import android.app.Activity;

import android.content.Context;

import android.net.wifi.WifiManager;

import android.os.Bundle;

import android.widget.TextView;

public class WifiEnableActivity extends Activity {

    /** Called when the activity is first created. */

    private WifiManager wifiManager; 

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE); 

       TextView text = (TextView)findViewById(R.id.txtWiFi);

          wifiManager.setWifiEnabled(true); 

          if(wifiManager.isWifiEnabled()){

              text.setText("Wifi State Enabled");

          }

        

    }

}

Then  some permission and user feature required in manifest file.
