Answer 1

Modify your async task like this: doing background method of asynctask runs in NON UI Thread, so we can not modify the ui elements from doInbackgroud so we have to return that result so that result will comes in postExecute method as parameter then we can modify the UI

    package com.example.phonebook;

    import java.util.ArrayList;
import java.util.List;

import org.apache.http.message.BasicNameValuePair;
import org.json.JSONObject;

import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.os.StrictMode;
import android.util.Log;
import android.widget.TextView;

import com.afbb.animationtest.R;

    public class Welcome extends Activity {
        TextView jsonParsed1,DataShow,hint_data;
        TextView jsonParsed ;
        JSONParser jsonParser = new JSONParser();
        JSONParser jobj = new JSONParser();
        private static String url = "http://192.168.1.10/android_connect/login_setup/show_data.php";
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
            .detectDiskReads().detectDiskWrites().detectNetwork()
            .penaltyLog().build());
            super.onCreate(savedInstanceState);
            setContentView(R.layout.welcome);
            jsonParsed1=(TextView)findViewById(R.id.jsonParsed);
            DataShow=(TextView)findViewById(R.id.show_all_data);
            hint_data=(TextView)findViewById(R.id.hint_datafor_value);
            jsonParsed = (TextView) findViewById(R.id.jsonParsed);
            String abt = getIntent().getStringExtra("mobile_number");
            new loginAccess().execute();
        }

    class loginAccess extends AsyncTask<String,Void,JSONObject> {
        private String Content;
        @Override
        protected JSONObject doInBackground(String... arg0) {
            String abt = getIntent().getStringExtra("mobile_number");
            List params = new ArrayList();
            params.add(new BasicNameValuePair("mobile_number", abt));
            JSONObject json = jsonParser.makeHttpRequest(url,"POST", params);
                Content = json.toString();
                Log.d("Create Response", Content);
     /****************** Start Parse Response JSON Data *************/
                try {
                    JSONObject jsonResponse = new JSONObject(Content);
                   String hint   = jsonResponse.optString("hint").toString();
                    return jsonResponse;
                 } catch (Exception e) {

                     e.printStackTrace();
                 }
                return null;
        }
        protected void onPostExecute(JSONObject result) {
            //Parse and update the UI
               jsonParsed.setText( OutputData );
             }
        }
    }

Answer 2

Remove below line from doInBackground method

 jsonParsed.setText( OutputData );

You can not touch view from outside main thread.

Answer 3

jsonParsed.setText( OutputData );
You just put above line in onPostExecute method after hint_data.setText( OutputData ); line and you will get the perfect output.
And also delete jsonParsed.setText( OutputData ); line from doInBackground method.
