Как я могу изменить активность на onpostexecute Android

Question

Итак, я попытался выполнить поиск в stackoverflow, но ни одно решение не будет полезно для меня. Я хочу получить данные с сервера, поэтому я отправляю запрос, а затем, если результат верен, мне нужно изменить активность.

package com.example.earchive; 

import java.io.BufferedReader; 
import java.io.InputStreamReader; 
import java.util.ArrayList; 
import java.util.List; 

import org.apache.http.HttpResponse; 
import org.apache.http.NameValuePair;

import org.apache.http.impl.client.DefaultHttpClient; 
import org.apache.http.message.BasicNameValuePair; 
import org.json.JSONArray; 
import org.json.JSONException; 
import org.json.JSONObject; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.AsyncTask; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 

public class LoginActivity extends Activity { 




    public String propertyNumber; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_login); 

    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.login, menu); 
/*** Work with login button ***/   
     final Button button = (Button) findViewById(R.id.login_bt); 
     button.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 

       FetchTask fetch = new FetchTask(); 

       EditText email = (EditText)findViewById(R.id.email); 
       fetch.email = email.getText().toString(); 
       EditText password = (EditText)findViewById(R.id.password); 
       fetch.password = password.getText().toString(); 
       fetch.v = v; 
       fetch.execute(); 

      } 
     }); 
/*** End of work with login button ***/   


     return true; 


    } 


    public class FetchTask extends AsyncTask<Void, Void, JSONArray> { 

     public JSONArray result_arr; 
     public String result_str,email,password,test; 
     public boolean is_loged; 
     public View v; 
     @Override 

     protected JSONArray doInBackground(Void... params) { 
      try { 
       HttpClient httpclient = new DefaultHttpClient(); 
       HttpPost httppost = new HttpPost("HERE MY LINK"); 

       // Add your data 
       List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 



       nameValuePairs.add(new BasicNameValuePair("em", this.email)); 
       nameValuePairs.add(new BasicNameValuePair("pa", this.password)); 
       nameValuePairs.add(new BasicNameValuePair("os", "android")); 
       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

       // Execute HTTP Post Request 
       HttpResponse response = httpclient.execute(httppost); 

       BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "utf-8"), 8); 
       StringBuilder sb = new StringBuilder(); 
       sb.append(reader.readLine()); 
       String line = "0"; 
       while ((line = reader.readLine()) != null) { 
        sb.append(line); 
       } 
       reader.close(); 
       String result11 = sb.toString(); 

       this.result_str = result11; 
       // parsing data 
       JSONArray arr = new JSONArray(result11); 




       return new JSONArray(result11); 
      } catch (Exception e) { 
       e.printStackTrace(); 
       return null; 
      } 
     } 

     @Override 
     protected void onPostExecute(JSONArray result) { 

      int auth; 
      if (result != null) { 
       JSONObject json_data; 
       try { 
        json_data = result.getJSONObject(0); 
        auth = json_data.getInt("auth"); 

        if(auth != 0) 
        { 
         startActivity(new Intent(LoginActivity.this, InboxActivity.class)); 


        } 
        else 
        { 

        } 
       } catch (JSONException e1) { 
        e1.printStackTrace(); 
       } 

      } else { 
       System.out.println("error occured"); 

      } 
     } 
    } 
} 

Моего InboxActivity класс

package com.example.earchive; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 

public class InboxActivity extends Activity { 

    public String propertyNumber; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_inbox); 

    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.login, menu); 
     return true;  
    }  
} 

Здесь мой код AndroidManifest (Рез/AndroidManifest.xml)

вот мой код из Реза/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.earchive" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="8"

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

</manifest>

Когда я запускаю мое приложение, и когда я отправить запрос пост я вижу ошибку "Unfortunately, APPNAME has stopped"

Что мне нужно сделать?

Спасибо всем!
