Unable to connect with internet

Question

Hi I'm trying to connect with internet with this code:

  DefaultHttpClient httpclient = new DefaultHttpClient();  
  HttpPost httppost = new HttpPost("http://192.168.0.100/webnet/xyz.php");
  String result = null;
  InputStream is = null;
  StringBuilder sb = null;
  HttpResponse response = httpclient.execute(httppost);

I registered Internet permission on manifest file

I got this error:

System.err android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1117)

I tests this app with API level 8

I have to ask, do you not have a search engine accessible from your location?, possible duplicate of [HTTP doesn't work in Android emulator](http://stackoverflow.com/questions/11277734/http-doesnt-work-in-android-emulator) — KevinDTimm, Aug 06 '13 at 12:40

You can not run long running task on main thread. please move your network related task in background.

Refer this : AsyncTask Android example

Since Android 3.0, you'll see this error when you're trying to make network requests from the main thread. Move this code to a separate thread.

Try this before executing this block of code. may works in some cases:

try {
                Class strictModeClass=Class.forName("android.os.StrictMode");
                Class strictModeThreadPolicyClass=Class.forName("android.os.StrictMode$ThreadPolicy");
                Object laxPolicy = strictModeThreadPolicyClass.getField("LAX").get(null);
                Method method_setThreadPolicy = strictModeClass.getMethod("setThreadPolicy",strictModeThreadPolicyClass );
                method_setThreadPolicy.invoke(null,laxPolicy);
            }
        catch (Exception e) {

            }

And Try this before asking questions here: "google.com" # agree with kevinDTimm

Anyway you SHOULD NOT call network on UI threads.

I'd say this is the worst solution for this problem, nevermind it was accepted. Don't do that! — Egor, Aug 06 '13 at 13:07
