Android POST Request to PHP

I try to develope an Android application. In this application, I need to send a POST request to a PHP page.

My code is at Java side:

DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://localhost/get.php");

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("mail", "asdasd"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpResponse httpresponse = httpclient.execute(httppost);

}catch(Exception e){
Toast.makeText(getApplicationContext(), "Didn't Happen",10).show();


xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="17"/>
<uses-permission android:name="android.permission.INTERNET"/>

android:theme="@style/AppTheme" >
android:label="@string/app_name" >

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

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


I have searched from a lot of websites and the code goes in catch block continuously.I also used HttpURLConnection and didn't work. Can you help me what can be the problem?

Answer Source

My problem was that I want to run my code in application main thread and main thread doesn't allow that. There are a few ways to solve this problem,

  1. Using asynctask to perform background operation
  2. Run the code in a new thread
  3. Enable network operation in MainActivity and this is what I choose for now by

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().detectNetwork().build(); StrictMode.setThreadPolicy(policy);
