You need the following permissions in your manifest file: <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.UPDATE_DEVICE_STATS"></uses-permission> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission> Then you can use the following in your activity class: wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE); wifiManager.setWifiEnabled(true); wifiManager.setWifiEnabled(false); Use the following to check if it's enabled or not boolean wifiEnabled = wifiManager.isWifiEnabled() You'll find a nice tutorial on the subject on this site. wifi toggle power toggle setting

android之手机震动Vibrate

repeat play sound

setContentView(R.layout.activity_main); // Button "button1" Button button1 = (Button) findViewById(R.id.button1); button1.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { // To-Do //ShowMsgDialog("哈哈哈"); //sendSMS("60399460", "message"); Thread thread = new Thread(){ @Override public void run(){ try{ playsound(); Thread.sleep(1000); run(); }catch (Exception e){ e.printStackTrace(); }finally{ } } }; //開始執行執行緒 thread.start(); } }); // End of Button "button1" } protected void playsound() { // TODO Auto-generated method stub MediaPlayer mp = MediaPlayer.create(MainActivity.this, R.raw.mysound); mp.setOnCompletionListener(new OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { // TODO Auto-generated method stub mp.release(); } }); mp.start(); }

play sound

 mp = MediaPlayer.create(Test.this, R.raw.mysound);
            mp.setOnCompletionListener(new OnCompletionListener() {

                @Override
                public void onCompletion(MediaPlayer mp) {
                    // TODO Auto-generated method stub
                    mp.release();
                }

            });   
            mp.start();

Send Message

This is works for me.

public void onCreate(Bundle savedInstanceState)
{
     super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
     btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
      btnSendSMS.setOnClickListener(new View.OnClickListener()
      {
         public void onClick(View v)
         {
             sendSMS("5556", "Hi You got a message!");

                       /*here i can send message to emulator 5556. In Real device 
                                                               you can change number  */

          }
      });
   }
  //---sends an SMS message to another device---

   private void sendSMS(String phoneNumber, String message)
   {
       SmsManager sms = SmsManager.getDefault();
       sms.sendTextMessage(phoneNumber, null, message, null, null);
    }

}

You can add this line in AndroidManifest.xml

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

Take a look at this

This may helpful for you.
