1.DOWNLOAD BLUESTACK APPLICATION FROM
(link:http://www.bluestack.com)
install blue stack on your host machine
if you start bluestack before eclipse and run your project , blue stack will automatically be available as
an adb device

2.if you exit any of the two connection may be terminated and be forced to make a new connection using this command
adb connect 127.0.0.1


access your platfoam-tool folder and start command inside there by pressing
CTRL+RIGHT-CLICK
then choose open command here option
and type the command inside there

adb connect 127.0.0.1

you should see successfully connected at 127.0.0.1:5555

then you are done configuring this simple emulator and start firing things up
thanx good luck

Android Custome Listview with images

in this tutorial you just need to create a project and copy all these codes and place them where they are supposed to be and you will have no trouble  the main and custome put them in your layout folder and enjoy
thanx for watching my example
MAIN JAVA CLASS
ListView2Activity .java
package com.listview;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class ListView2Activity extends Activity implements OnItemClickListener
{
    /** Called when the activity is first created. */

ListView lview;
ListViewAdapter lviewAdapter;


private final static String month[] = {"January","February","March","April","May",
"June","July","August","September","October","November","December"};

private final static String number[] = {"Month - 1", "Month - 2","Month - 3",
"Month - 4","Month - 5","Month - 6",
"Month - 7","Month - 8","Month - 9",
"Month - 10","Month - 11","Month - 12"};
private final static String sayings[]={"Hunger","Rain","Love","Sex","Summer","poverty","Autum","what","yelling","News","Terror","Snow"};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        lview = (ListView) findViewById(R.id.listView2);
        lviewAdapter = new ListViewAdapter(this, month, number);

        System.out.println("adapter => "+lviewAdapter.getCount());

        lview.setAdapter(lviewAdapter);

        lview.setOnItemClickListener(this);
    }

public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), month[position]+"\t is the month of \t"+sayings[position], Toast.LENGTH_LONG).show();
//Toast.makeText(this,"Title => "+month[position]+"=> n Description"+number[position], Toast.LENGTH_SHORT).show();
}
}

here is the list view adapter that extends the Baseadapter class to handle the images

package com.listview;

import android.app.Activity;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.ImageView;

import android.widget.TextView;

public class ListViewAdapter extends BaseAdapter

{

Activity context;

String title[];

String description[];

public ListViewAdapter(Activity context, String[] title, String[] description) {

super();

this.context = context;

this.title = title;

this.description = description;

}

public int getCount() {

// TODO Auto-generated method stub

return title.length;

}

public Object getItem(int position) {

// TODO Auto-generated method stub

return null;

}

public long getItemId(int position) {

// TODO Auto-generated method stub

return 0;

}

private class ViewHolder {

        TextView txtViewTitle;

        TextView txtViewDescription;

        ImageView image;

        TextView quotes;

}

public View getView(int position, View convertView, ViewGroup parent)

{

// TODO Auto-generated method stub

ViewHolder holder;

LayoutInflater inflater =  context.getLayoutInflater();

if (convertView == null)

{

convertView = inflater.inflate(R.layout.listitem_row, null);

holder = new ViewHolder();

holder.txtViewTitle = (TextView) convertView.findViewById(R.id.textView1);

holder.txtViewDescription = (TextView) convertView.findViewById(R.id.textView2); 

holder.image=(ImageView)convertView.findViewById(R.id.imageView1);

holder.quotes=(TextView)convertView.findViewById(R.id.quotes);

convertView.setTag(holder);

}

else

{

holder = (ViewHolder) convertView.getTag();

}

holder.txtViewTitle.setText(title[position]);

holder.txtViewDescription.setText(description[position]);

holder.image.setBackgroundResource(images[position]);

holder.quotes.setText(sayings[position]);

//holder.image.setImageResource(R.drawable.ic_launcher);

return convertView;

}

private final static String sayings[]={"Hunger","Rain","Love","Sex","Summer","poverty","Autum","what","yelling","News","Terror","Snow"};

private Integer[] images={R.raw.brightday,R.drawable.ic_launcher,R.raw.sunlaugh,R.raw.stormcloud,R.raw.hotsun,R.raw.brightday,R.raw.eveningcloud,R.raw.cloudlove,R.raw.springs,R.raw.stormcloud,R.raw.xmas,R.raw.cloudwhite};

}

main.xml

<?xml version="1.0" encoding="utf-8"?>

    <ListView

    android:layout_height="wrap_content"

    android:id="@+id/listView2"

    android:layout_width="match_parent">

    </ListView>

</LinearLayout>

then the custom xml 

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

  xmlns:android="http://schemas.android.com/apk/res/android"

  android:orientation="vertical"

  android:layout_width="match_parent"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="TextView"

        android:textAppearance="?android:attr/textAppearanceLarge" >

    </TextView>

    <TextView

        android:id="@+id/textView2"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

    <ImageView

        android:id="@+id/imageView1"

        android:layout_width="wrap_content"

</LinearLayout>

ANDROID RETRIEVING DATA FROM MYSQL DATABASE

first things first
create a table called
student
having fields NAME and YEAR and AGE from your php mypublicadmin
2.create a php file index.php
<?php
  header('Content-type: application/json');
  mysql_connect("127.0.0.1","root","");
  mysql_select_db("android");
  $sql=mysql_query("select * from students");
  while($row=mysql_fetch_assoc($sql))
  $output[]=$row;
  json_encode($output);
  print(json_encode($output));
  mysql_close();
?>
then after this go to eclipse MAINACTIVITY and add this

        try {
            DefaultHttpClient client = new DefaultHttpClient();
            HttpGet request = new HttpGet("http://10.10.6.124/android/index.php");
            HttpResponse response = client.execute(request);
            HttpEntity entity=response.getEntity();
            data=EntityUtils.toString(entity);
            Log.e("STRING", data);
            try {

    for(int i=0;i<json.length(); i++)
    {
    JSONObject obj=json.getJSONObject(i);
    String name=obj.getString("name");
    String year=obj.getString("year");
    String age=obj.getString("age");
    Log.e("STRING", name);
    r.add(name);
    r.add(year);

    list.setAdapter(adapter);
   
    }
   
    } catch (JSONException e) {

        }
     
     
    }


}

xml file

in your manifest add permissions to internet

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.example.httpclient"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="9"

        android:targetSdkVersion="17" />

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

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.example.httpclient.HTTPCLIENT"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

and thats all if this fails then change your operating system hhahahahahahahahahaha

Google map api v2 keys not working

your manifest should look like this okay
where you see my package name replace it with yours and things should work
if you see a blank screen with gestures enabled there are two things that are not right
data connection problems
and the api key
so make sure you run the app on a real device not an emulator and fail not to import the lib project from the sdk-extra folder
