Front End Code for Android Vibration

$*#@%$ ca-app-pub-4111868940087848/3418151202

To vibrate a phone we need following Permission Do not forget to declare this permission in Manifest.

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

We can Vibrate a Phone Using an Activity  , Service and Using Threads.

Using Activity will not be a good Idea because it takes time to vibrate the Phone and an Activity always runs in foreground.

We will implement using Service because  a Service runs in Background.

for we need to have an Object of Class Vibrator, we do not create the Object directly but we get Vibrate System Service.

Vibrator v = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);

Add    <uses-permission android:name="android.permission.VIBRATE"/>  in Your Manifest

Code to Vibrate the Phone

Vibrator v = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);

                                     // pass the number of millseconds fro which you want to vibrate the phone here we
                                     // have passed 2000 so phone will vibrate for 2 seconds.


                                   // If you want to vibrate  in a pattern
                                   //  long pattern[]={0,800,200,1200,300,2000,400,4000};
                                   // 2nd argument is for repetition pass -1 if you do not want to repeat the Vibrate
                                   // v.vibrate(pattern,-1);

There are a lot of advices when it comes to stopping those annoying hiccups - holding your breath and eating sugar and what not. When you get hiccups, simply bend forwards and drink a glass of water from the other side as demonstrated in the picture. It will cure the hiccups immediately by restricting the spasmodic inhalation characteristics of hiccups.

While traveling abroad, you can use Google Maps as a free GPS without an international data plan. While offline, simply zooming to a map area you want in the maps app, and type “ok maps” into the search box. This data will be available even when you do not have data connectivity.

Working with Images In Android

Working with Images

Images are used to make the user interface interactive and more user friendly. Images can be used with almost all the widgets like TextView, EditText, Buttons, ImageButtons etc.
To use the images we need to create a “drawable” folder in “res” folder and put all the images in this “drawable” folder.
Demo App : “Working with Images”

What we will do : We have five images named “one”, “two”, “three”, “four” and “five”.


We have five buttons on main screen named  “One”, “Two”, “Three”, “Four” and “Five”.
When clicks on a particular button, we will show the respective image in Image View using  method setImageResource(resourceId);

<LinearLayout xmlns:android=""
    android:orientation="vertical" >

    android:orientation="horizontal" >

        android:onClick="showTwo" />
        android:onClick="showFour" />
        android:src="@drawable/one" />
public class MainActivity extends Activity
    ImageView myImageView;
       protected void onCreate(Bundle savedInstanceState)
              // get the reference of image view
              myImageView = (ImageView)findViewById(;

       /* when user clicks on Button "One"
        * set the particular image in myImageView
       public void showOne(View V)
       /* when user clicks on Button "Two"
        * set the particular image in myImageView
       public void showTwo(View V)
       /* when user clicks on Button "Three"
        * set the particular image in myImageView
       public void showThree(View V)
       /* when user clicks on Button "Three"
        * set the particular image in myImageView
       public void showFour(View V)
       /* when user clicks on Button "Five"
        * set the particular image in myImageView
       public void showFive(View V)


     Main Screen(When nothing selected)                           When Button “One” Selected

          When Button “Three” Selected                               When Button “Five” Selected
