    Thank you for fast reply πŸ˜‰
    I have another question… I am working on an application, which must send three parameters to PHP server.. That PHP server must write them into mysql database. Now I am having big problems sending these data over HTTP from Android to my PHP server.. I tried so many tutorials and it doesn’t work.. Is there any option you could send me very basic sample code, sending data to server and receive it in php file?

    Thank you very very much!!!! πŸ˜‰

      The simplest thing is you can modified the script above, use JSON to deliver your parameter from android to PHP.

      Here’s the diagram:
      Android (JSON) -> HTTP POST -> PHP (json_decode($_POST[‘JSON’]))

      You can use json_decode() function in PHP to convert JSON into an Array..

      or you can see this:

    Hi can you tell me how I can put retrieved data into a ListView? I’m using this:

    String name;
    jArray = new JSONArray(result);
    JSONObject json_data=null;
    for(int i=0;i<jArray.length();i++){
    json_data = jArray.getJSONObject(i);
    }catch(JSONException e1){
    Toast.makeText(getBaseContext(), "Nessun quiz trovato" ,
    } catch (ParseException e1) {

    // first tab
    TabSpec ts = myTabHost.newTabSpec("TAB_TAG_1");
    ts.setIndicator("Available quiz",
    ts.setContent(new TabHost.TabContentFactory() {

    public View createTabContent(String tag) {

    /* ArrayList appAL = new ArrayList(50);
    String stringaInizio = “;”;
    String stringaFine = “;”;
    appAL = fullArrayInt(appoggio, stringaInizio, stringaFine);*/

    ArrayAdapter adapter = new ArrayAdapter(


    return ls1;



    Well, i want to put the retrieved data inside of that ArrayAdapter but i don’t know what to put after the context (MainMenuActivity.this, R.layout.simple….. )

    Thanks for your help!

    Hello, in your PHP code, does “print(json_encode($output))” send output data to Android client ? I thought “print” command is used for displaying purpose. Please, correct me if am wrong. Thanks

    Hi, thanks for the tutorials are very helpful.

    I want to ask some help. Turns out I have a server on localhost: http://localhost/backend/json.php and json.php file is as follows:


    // now, the output in JSON format:
    header(‘Content-type: application/json’);
    echo json_encode(array(‘descargas’=>$descargas));

    // disconnect from the db


    I need to know how to get the data as a list json.php. I have proven with your tutorial but I have left.

    Would be very grateful if you could help me.

    Sorry for my English, I’m Spanish xD.

    Hey, thanks for your interesting post, I was wondering if you can provide an example where android device wants to update server side’s database. Assume we have a content provider on android device and we would like to send data upon insertion to the database on client side (Android device) or upon update on the client. Curious to find out how exactly the other way around works for this example.

    I am using exactly the same thing in my app. But one thing makes me think a lot.
    A clever user can listen the network and easily get the php file that the program POSTs. The POST values are fragile and I dont want anyone to post outside of my app.
    How can I accomplish this security issue?

    How n00b can i get?

    It doesnt say where to put the code.
    I believe that the visible design should be placed in res->layout->myproject.xml file, and that android-code should be in my main java-file located in com->myproject-> ?

    However, I get TONS of errors when placing the code in java-file. Most of them i can get rid of by using “quickfixes”(although i dont know if i choose the right ones). But i also get errors that dont get any quickfixes so what to do…

    Is it possible that you can update this post with description to where we should put the code, also if you expect us to actually get errors and to resolve them for us selves, could we get a more detailed description so we understand what should be converted to what aso?

    Have searched the internet for days and have found several tutorials on how to do this but i never get it to work becouse of code-errors, and i do not have enough experiance in java/android to work it out myself.. I use googles ADT with eclipse and open a new project(android project).. Could it be that you use another IDE that causing my errors?

    Is’nt it odd that google’s android development forums/pages doesnt have an “how” to on this subject? or do i just dont know where it is?

    has the ability to absorb heat within the skin which is
    a precursor of acne. The good news is that effective natural acne treatments really do exist.
    You can use it for chapped lips, dry skin, and anything else you would normally use petroleum jelly for.
