Simple Client Server Communication In Android

I was working of an android project recently and now I guess .. I am done with my part. Yeah its a team of 4 and the project was divided accordingly. One of the responsibilities I was assigned was the development of Online Leader Board. While I was working, I searched through Internet and found a few examples as well, – I wonder which question Google couldn’t answer?

All of them were either to much complicatedly explained or didn’t cover the complete concepts behind a complete Client Server Communication In Android. Either the writers were assuming that the person who’ll land of this page will be intelligent enough to guess the other part or were simple not interested of posting a complete solution to someone’s problem. And for the same reason I am writing this post, so if someone else lands on this page while searching the same problem he/she could find a complete solution to their needs.

In this tutorial I’ll be assuming that you at least:

Have a basic knowledge of android
Have already developed a few small android application (e.g calculators, alarm, reminder etc.)

If you are new to android development, please leave me a comment and I might start from the beginning.

The Real Post Starts From Here:

In spite of using the 3rd party API’s, json classes etc. I’ll be using the default HttpClient from org.apache.http package. For those who want to get the code snippet just and not want me to explain it, the code will be as follows:

HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet("http://example.com/script.php?var1=androidprogramming");
try {
    HttpResponse response = httpclient.execute(httpget);
    if(response != null) {
        String line = "";
        InputStream inputstream = response.getEntity().getContent();
        line = convertStreamToString(inputstream);
        Toast.makeText(this, line, Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(this, "Unable to complete your request", Toast.LENGTH_LONG).show();
    }
} catch (ClientProtocolException e) {
    Toast.makeText(this, "Caught ClientProtocolException", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
    Toast.makeText(this, "Caught IOException", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
    Toast.makeText(this, "Caught Exception", Toast.LENGTH_SHORT).show();
}

HttpClient httpclient = new DefaultHttpClient();

HttpGet httpget = new HttpGet("http://example.com/script.php?var1=androidprogramming");

try {

HttpResponse response = httpclient.execute(httpget);

if(response != null) {

String line = "";

InputStream inputstream = response.getEntity().getContent();

line = convertStreamToString(inputstream);

Toast.makeText(this, line, Toast.LENGTH_SHORT).show();

} else {

Toast.makeText(this, "Unable to complete your request", Toast.LENGTH_LONG).show();

}

} catch (ClientProtocolException e) {

Toast.makeText(this, "Caught ClientProtocolException", Toast.LENGTH_SHORT).show();

} catch (IOException e) {

Toast.makeText(this, "Caught IOException", Toast.LENGTH_SHORT).show();

} catch (Exception e) {

Toast.makeText(this, "Caught Exception", Toast.LENGTH_SHORT).show();

}

GET is used to know how actually the code is working.
Default strings from android strings.xml are not used to avoid useless explanation for this tutorial but they are the recommended way too use while designing an app rather then hard coded strings.

Client server communication is this much simple when it comes to android.

Create HttpClient with the default constructor.
Create a HttpGet or HttpPost object depending upon your needs, in this case I made a GET object so that we can know whats going on.
Initialize the object with a GET or POST url.
Execute the GET/POST object through the Http and you’ll get the server’s response in the response object of HttpResponse.

Fetching Data From HttpResponse:

Now the next part is how to fetch data received from the server in HttpResponse object. The server response can be type casted into InputStream object which will then parse the response into simple String. here is the code to do that:

private String convertStreamToString(InputStream is) {
    String line = "";
    StringBuilder total = new StringBuilder();
    BufferedReader rd = new BufferedReader(new InputStreamReader(is));
    try {
        while ((line = rd.readLine()) != null) {
            total.append(line);
        }
    } catch (Exception e) {
        Toast.makeText(this, "Stream Exception", Toast.LENGTH_SHORT).show();
    }
    return total.toString();
}

private String convertStreamToString(InputStream is) {

String line = "";

StringBuilder total = new StringBuilder();

BufferedReader rd = new BufferedReader(new InputStreamReader(is));

try {

while ((line = rd.readLine()) != null) {

total.append(line);

}

} catch (Exception e) {

Toast.makeText(this, "Stream Exception", Toast.LENGTH_SHORT).show();

}

return total.toString();

}

So now the code is completed for the client side and we will be focusing on the server side script. The example above will show a notification of the string response the server will send back, here is the code snippet I wrote in php for the server side.

$connection = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die('Unable to connect');
$db = mysql_selectdb(DB_NAME,$connection) or die('Database not found');
if(isset($_GET['var'])) :
    $query = "SELECT [a few parameters] FROM [some table] WHERE [some conditions]";
    $resultset = mysql_query($query);
    $row = mysql_fetch_array($resultset)
    echo $row['[column name]'];
else:
    echo "No get Request Received";
endif;

$connection = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die('Unable to connect');

$db = mysql_selectdb(DB_NAME,$connection) or die('Database not found');

if(isset($_GET['var'])) :

$query = "SELECT [a few parameters] FROM [some table] WHERE [some conditions]";

$resultset = mysql_query($query);

$row = mysql_fetch_array($resultset)

echo $row['[column name]'];

else:

echo "No get Request Received";

endif;

Warning:

Implement proper checks for data filtration. The code above was meant for the tutorial and is not enough to use in a market application.

This completes this small tutorial here, now a few of the most asked questions while doing the client server communication:

Why not use the XML approach while performing the client server data transfer operations:
This was my first android application which used internet permissions and fetched data on runtime from server, I found it more interesting to work first manually with writing my own script and then go for the proper XML approach.
Why not use the JSON library for client server application in fact of using an array for GET or POST request:
Answer remains the same for this question as well. I have implemented my own methods and know how HTTP works in android. Next I’ll be using JSON and then switch to XML, JSON tutorial will be the next one in this series.
Some other questions:
Post them into the comments section and I’ll be happy to answer them right away. If you are enough experienced and found this approach not practicable while developing apps for the market, please provide your valuable feedback in that case as well. We warmly welcome a healthy and fruitful discussion here.

Internet Permissions

To get access to internet at Android, following field must be included to AndroidManifest.xml file of the project:

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

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

  You’ll get the data echo’ed or printed by your php script in HttpResponse variable which then can be converted into a Java String as mentioned above to use in your programming logic. A point to be noted is that we receive a buffered stream in HttpResponse, so if you can manage to get along with it then there isn’t any benefit of converting the stream into String first. Hope I have made you clear, if you have any more doubts post them here and I’ll answer them as quickly as I can.

      I suppose the data (Events) you’ll be extracting from the web server is kept in a professional manner with time, date and its category stamped. For this example assume we have a table with (Please bother me with database not being normalized to level 3, its just an example ): 1. Event name 2. Event type 3. Time 4. Date We can simply call our script with an appropriate sql command to get us events related to sports category via passing some values like: example.com/event-filtering-script.php?eventtype=sports&date=02022012 The script will fetch the data out of these variables and ran a SQL query similar to: SELECT * FROM WHERE event_type=’sports’ AND date > ’23/12/2011′ and then will print the data which will then return to your response variable. P.S: The query might won’t work for the time and date but its just not at the top of my head. I’ll read it from the mySQL reference manual and post it here if get time, but its not a promise.

  The procedure would be the same as in this case but you have to encode the to bytestreams to make the multimedia attachments works, that what I can guess for now as I haven’t tried it myself, but I will once getting done with my exams and report back. Thanks for te appreciation though.

  Hi Sumeet, Well GPS alone can not do this job, although you can get location using GPS and then transfer the coordinates to the app server for further processing. Of course you’ll have to add location based services permission in your application.
