根据android发送的电子邮件地址从服务器获取具有特定记录的列表视图

I have a table in the server and I want to retrieve specific records based on email address sent from android java code.

The email address is stored in global variable and I can get its value but I don't know how to send its value to the server and get the records.

my code retrieves all the records from the table

Please Help me to do it, I tried to do it for 3 days but with no solution

this is my PHP code :

<?php
$objConnect = mysql_connect("****","******","******");
$objDB = mysql_select_db("******");
$strSQL = "SELECT * FROM Appointment ";
$objQuery = mysql_query($strSQL);
$intNumField = mysql_num_fields($objQuery);
$resultArray = array();
while($obResult = mysql_fetch_array($objQuery))
{
    $arrCol = array();
    for($i=0;$i<$intNumField;$i++)
    {
        $arrCol[mysql_field_name($objQuery,$i)] = $obResult[$i];
    }
    array_push($resultArray,$arrCol);
}

mysql_close($objConnect);

echo json_encode($resultArray);
?>    

this is my java code :

    I found the answer and the problem is solved

    It was an easy solution

    I just put my condition in the java code with no changes in the PHP code

    the changes are :

    try {
            JSONArray data = new JSONArray(getJSONUrl(url));
    
            final ArrayList<HashMap<String, String>> MyArrList = new ArrayList<HashMap<String,    String>>();
            HashMap<String, String> map;
    
            for(int i = 0; i < data.length(); i++){
                JSONObject c = data.getJSONObject(i);
                map = new HashMap<String, String>();
                map.put("V_ID", c.getString("V_ID"));
                map.put("V_Type", c.getString("V_Type"));
                map.put("V_Model", c.getString("V_Model"));
                map.put("V_Year", c.getString("V_Year"));
                map.put("V_Plate", c.getString("V_Plate"));
                map.put("ImagePath", c.getString("ImagePath"));
                map.put("Email", c.getString("Email"));
    
                String email = c.getString("Email");
                  GlobalClass globalVariable = (GlobalClass) getApplicationContext();
                  // Get name and email from global/application context
                  final String Email  = globalVariable.getEmail();
    
                 if(email.equals(Email))
                MyArrList.add(map);
            }
