In your Main Activity:

create ANDROID project with this structure : in your main layout : in your main Activity :

Use this code for get all information O/P: (in emulator) in Android Phone :

1 ) First In androidmanifest.xml file give the permission of internet given below :      <uses-permission android:name="android.permission.INTERNET"></uses-permission> 2) Go to res/layout/main.xml :     3 ) Go to Acitivity :- 

 For many application, you have to check internet connection in emulator or in handset. First In androidmanifest.xml file give the permission of internet given below :      <uses-permission android:name="android.permission.INTERNET"></uses-permission>     <uses-permission android:name="android.permission.ACCESS_WIFI_STATE">     </uses-permission>     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE">    </uses-permission> Now add Internet Connection code given below : 

1) Go to res/Lauout/main.xml :- 2) Now Nextgot o res/Layout/row.xml :- 3) Now go to main Activity:- 

1. Open the Android AVD and SDK Manager  2.  Select Available Packages in the left panel of AVD Manager. 3.  Click “Add ADD-on Site” and enter the URL below. http://innovator.samsungmobile.com/android/repository/srepository.xml   4. Check Samsung GALAXY Tab Add-on packages and click install button. 5. Check Samsung GALAXY Tab Add-on license & Click install button. 6) After downloading and installation of GALAXY Tab Add-on, you should restart ADB (Android Debug Bridge) or Eclipse. The important specs of this device, from an Emulator perspective, are: Target platform: Android 2.2, Galaxy Tab Screen Info: High Density, despite the fact that it’s not, this is what it reports, WSVGA (1024×600) No keyboard Has dual cameras Let’s create an AVD configuration called GalaxyTab: Within Eclipse, launch the Android SDK and AVD Manager Select “Virtual Devices” from the left-hand options Click the “New” button to create a new AVD configura...

 To implement this tutorial you should have basic knowledge of how to run PHP script and start server.  If we talk about client-server architecture, client is Android device and in server side there is a combination of PHP Script and MySQL. In short, PHP Script sits in middle as shown in image. Lets suppose that we have a MySQL database named Employee, and a table int created, with the following SQL: CREATE TABLE `employee` (   `emp_id` int(11) NOT NULL auto_increment,   `emp_name` varchar(100) NOT NULL,   PRIMARY KEY  (`emp_id`) ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ; The PHP code will be very simple: Now Create Android Project :  The Android part is only a bit more complicated: -use a HttpPost to get the data -convert response to string -parse JSON data in to List In Your First Activity : O/P :

JSON String private String jString = "{\"menu\": {\"id\": \"file\", \"value\": \"File\", \"popup\": " + "{ \"menuitem\": [ {\"value\": \"New\",   \"onclick\": \"CreateNewDoc()\"}, " + "{\"value\": \"Open\", \"onclick\": \"OpenDoc()\"}, {\"value\": \"Close\", " + "\"onclick\": \"CloseDoc()\"}]}}}"; Use this code to parsing JSON. out put of this code :

Create your layout: In Your first Activity : 

This example shows  custom   Grid View, have a ImageView and TextView in each grid like this:  1) Create a  folder  /res/drawable to hold the different  pictures . 2)  Modify main.xml to have a   GridView :  <?xml version="1.0" encoding="utf-8"?> <GridView xmlns:android="http://schemas.android.com/apk/res/android"          android:layout_width="fill_parent"  android:id="@+id/gridView1"  android:layout_height="fill_parent" android:horizontalSpacing="5px" android:verticalSpacing="5px" android:stretchMode="columnWidth" android:columnWidth="60px" android:numColumns="3" android:gravity="center" /> Now, 3)   Implement mygrid.xml in folder /res/layout/, it's the layout of individual grid.  <?xml version="1.0" encoding="utf-8"?>  <LinearLayout    android:id="@+id/linearLayout1"   android:layout_widt...

A sample application that shows how to use resource directory qualifiers to show different resources to different screen configurations. create application in res folder create new folder for layout name layout-land . in res/layout/main.xml in res/layout-land/main.xml also add in your Androidmanifest.xml file check output in different size screen  1. Android 2.2 Skin : WVGA  -> when screen is portrait -> when screen is landscape 2. Android 2.3.3 Skin : WVGA854 -> when screen is landscape - > when screen is portrait it is also tested in Android 2.2 skin HVGA
