I need help adding Thread to the connection of web service or it will not run

Question

I am trying to make a call to a web service when I click the button, the button part and input works now i am trying to actually call web service, but i need Threads to do so, but i don't know them. People are saying to use AsyncTask.

LogCat log for callWS: callWS: "http://pastebin.com/nuLnPQz8"

callWS FUNCTION:: It will allways crash because it requires Threads.

XML Code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

Answer 1

This is a common mistake. You call the TextView's setText method with an integer argument

int a = 2 + 3; // Runs fine
TextView text = (TextView) findViewById(R.id.button_one); 
text.setText(a); // makes ERROR

The setText method with an integer argument is designed to take a resource ID (R.string.some_string_key).

That is why the logs says

Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x5

You try to get a String from strings.xml from the generated R.java file with an ID of 5

Just replace the line that fails with

text.setText(String.valueOf(a)); // should work

Answer 2

I think the problem is this line.

TextView text = (TextView) findViewById(R.id.button_one);

You convert your BUTTON button_one to a TEXTVIEW. I don't know if this is possible.

Try to use

TextView text = (TextView) findViewById(R.id.output);

and test if your code would work.

Answer 3

When the button is clicked you are trying to do some network related operations. In Android, any network related operations should not be done in the main UI thread.

So on the button click either start a new thread and get the information from network or use Async Task.
