response = httpclient.execute(new HttpGet(uri[0]));
StatusLine statusLine = response.getStatusLine();

if(statusLine.getStatusCode() == HttpStatus.SC_OK){
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.getEntity().writeTo(out);
out.close();
rarr = "Inside status";
//responseString = out.toString();
rarr = out.toString();
} else{
rarr = "first Error";
//Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());

}
} catch (ClientProtocolException e) {

below is how I call it, i then try to assign task.rarr to a toast but its always blank.

[HIGH]
RequestTask task = (RequestTask) new RequestTask().execute("http://www.mycashadvance.co.uk/WCFService/HelloWorld");
[/HIGH]
Toast
[HIGH]
Toast.makeText(MainActivity.this, task.rarr, Toast.LENGTH_SHORT).show();
[/HIGH]

I've added

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

to the manifest

Any help would be appreciated.

 

Hello,

I haven't as of yet no,

I did try connecting to this wcf service via another. Net application and that was a succes, someone has told me to,move the toast inside on the onPOST method which gets called after the request task but when , put the toast there it asks for a context which i Assumed was a class so I placeed Requesttask there and it didn'. Like it someone then said use entityulis.tostring and well that's where got confused, reason for this is because rarr cant be read but by puttig it inside the onPOST method I'd be able to read it

 

Thanks for the response(s) LAst night i placed the toast inside the onPost method and below is what I recieved from the stacktrace

12-09 14:39:09.274: E/AndroidRuntime(1613): FATAL EXCEPTION: main 12-09 14:39:09.274: E/AndroidRuntime(1613): Process: com.example.newapplication, PID: 1613 12-09 14:39:09.274: E/AndroidRuntime(1613): java.lang.NullPointerException 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.widget.Toast.(Toast.java:93) 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.widget.Toast.makeText(Toast.java:241) 12-09 14:39:09.274: E/AndroidRuntime(1613): at Methods.RequestTask.onPostExecute(RequestTask.java:64) 12-09 14:39:09.274: E/AndroidRuntime(1613): at Methods.RequestTask.onPostExecute(RequestTask.java:1) 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.os.AsyncTask.finish(AsyncTask.java:632) 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.os.AsyncTask.access$600(AsyncTask.java:177) 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:645) 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.os.Handler.dispatchMessage(Handler.java:102) 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.os.Looper.loop(Looper.java:137) 12-09 14:39:09.274: E/AndroidRuntime(1613): at android.app.ActivityThread.main(ActivityThread.java:4998) 12-09 14:39:09.274: E/AndroidRuntime(1613): at java.lang.reflect.Method.invokeNative(Native Method) 12-09 14:39:09.274: E/AndroidRuntime(1613): at java.lang.reflect.Method.invoke(Method.java:515) 12-09 14:39:09.274: E/AndroidRuntime(1613): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:777) 12-09 14:39:09.274: E/AndroidRuntime(1613): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:593) 12-09 14:39:09.274: E/AndroidRuntime(1613): at dalvik.system.NativeStart.main(Native Method)




My onPost method looked like this

[HIGH]
@Override protected void onPostExecute(String result) { super.onPostExecute(result); Toast.makeText(null, rarr, Toast.LENGTH_SHORT).show(); }
[/HIGH]

again I tried placing RequestTask.class as the context but it didnt like it so I tried null and got the above stack trace

 

[HIGH]
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);

Toast.makeText(MainActivity.this, "Bleee", Toast.LENGTH_SHORT).show();
}

[/HIGH]

gives me the following error
No enclosing instance of type MainActivity is Accessible in scope

I then change it to

[HIGH]
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);

Toast.makeText(MainActivity.class, "Bleee", Toast.LENGTH_SHORT).show();
}
[/HIGH]
which again erros as its moaning about MainActivity.class

Do you happen to have a working example of this?

The method I'm trying to call which is inside the service is ReturnVal

 

Nope not inside a fragment, ill give that a go tonight.
