Android Http Post + Web Service Php

I have a web service in PHP which returns a String, he recives two parametres, id and te. I've tested its using with the mozzila addon poster, so i decided to use it for my android

Solution 1:

for Http Post i'll suggest you to use AsyncTask<> which will run in separate thread from UI here is the code i am using since two months and its working fine

privateclassHttpAsyncTaskextendsAsyncTask<String, Void, String> {
 private String id,te;
 publicHttpAsyncTask(String id,String te){
        this.id = id;
        this.te = te;

    }

        @Overrideprotected String doInBackground(String... urls) {



            return POST(urls[0]);
        }
        // onPostExecute displays the results of the AsyncTask.@OverrideprotectedvoidonPostExecute(String result) {
            Toast.makeText(getBaseContext(), "Data Sent!", Toast.LENGTH_LONG).show();
       }
    }
publicstatic String POST(String url){
    InputStreaminputStream=null;
    Stringresult="";
    try {

        // 1. create HttpClientHttpClienthttpclient=newDefaultHttpClient();

        // 2. make POST request to the given URLHttpPosthttpPost=newHttpPost(url);
       // pass parameters in this way

       List<NameValuePair> nameValuePairs = newArrayList<NameValuePair>(2);
    nameValuePairs.add(newBasicNameValuePair("id", "value "));
    nameValuePairs.add(newBasicNameValuePair("te", "value"));

    //add data
    httppost.setEntity(newUrlEncodedFormEntity(nameValuePairs));

        // 8. Execute POST request to the given URLHttpResponsehttpResponse= httpclient.execute(httpPost);

        // 9. receive response as inputStream
        inputStream = httpResponse.getEntity().getContent();

        // 10. convert inputstream to stringif(inputStream != null)
            result = convertInputStreamToString(inputStream);
        elseresult="Did not work!";

    } catch (Exception e) {
        Log.d("InputStream", e.getLocalizedMessage());
    }
 // 11. return resultreturn result;

}

privatestatic String convertInputStreamToString(InputStream inputStream)throws IOException {
    // TODO Auto-generated method stubBufferedReaderbufferedReader=newBufferedReader( newInputStreamReader(inputStream));
    Stringline="";
    Stringresult="";
    while((line = bufferedReader.readLine()) != null)
        result += line;

    inputStream.close();
    return result;

}

for passing values you can create constructor like this.

form your activity do this

HttpAsyncTaskhttpAsyncTask=newHttpAsyncTask(id,te);//this will pass variables values StringResultfromServer= httpAsyncTask.execute(urlStr);// String ResultfromServer is your response string

and in AsyncTask I've created constructor

this is very helpful for me hope it will help you too

Solution 2:

Look at below code for posting data to php

classPlaceOrderextendsAsyncTask<Void, Void, Void> {

    @Overrideprotected Void doInBackground(Void... params) {

    // TODO Auto-generated method stubtry {

    HttpClienthttpClient=newDefaultHttpClient();

    HttpPosthttpPst=newHttpPost(

    "http://appdomain.hol.es/webService.php");

    ArrayList<NameValuePair> parameters = newArrayList<NameValuePair>(

    2);
    // add ur parameter here
    parameters.add(newBasicNameValuePair("id", value1);
    parameters.add(newBasicNameValuePair("te", value2);
    httpPst.setEntity(newUrlEncodedFormEntity(parameters));

    HttpResponsehttpRes= httpClient.execute(httpPst);



    String str=convertStreamToString(httpRes.getEntity().getContent()).toString();

    Log.i("mlog","outfromurl"+str);


    } catch (UnsupportedEncodingException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

    } catch (ClientProtocolException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

    } catch (IOException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

    }

    returnnull;

    }

    }

    publicstatic String convertStreamToString(InputStream is) {

    BufferedReaderreader=newBufferedReader(newInputStreamReader(is));

    StringBuildersb=newStringBuilder();

    Stringline=null;

    try {

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

    sb.append(line + "\n");

    }

    } catch (Exception e) {

    e.printStackTrace();

    } finally {

    try {

    is.close();

    } catch (IOException e) {

    e.printStackTrace();

    }

    }

    return sb.toString();

    }
