No Activity found to handle Intent { act=com.application.activity.MainActivity }

I create 2 packges : one for mainactivity, another for login interface
Here's the file AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.application.activity"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.application.login.Login"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
        <activity
            android:name=".activity.MAINACTIVITY"
             android:configChanges="orientation|keyboardHidden"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="com.application.activity.MAINACTIVITY" />

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

</manifest>

here's the Login class :

package com.application.login;

import java.util.ArrayList;

import android.app.Activity;
import android.app.Dialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

import com.application.activity.R;

public class Login extends Activity  implements View.OnClickListener{
	
	ArrayList<Integer> tabid = new ArrayList <Integer>();
	ArrayList <Double> tabpass = new ArrayList <Double>();
	Button login;
	Button cancel;
	EditText id;
	EditText pass;
	int n= tabid.size();
	int m= tabpass.size();
	
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.login);

    

		DatabaseLogin db = new DatabaseLogin(this);
		db.open();
		tabid = db.getIdentifiant();//tableau contient  tout les identifiant 
		tabpass = db.getPassword();//tableau contient tout les mot de passe
	
		initialize();

		login.setOnClickListener(this);
		cancel.setOnClickListener(this);
		
		db.close();
	}

	private void initialize() {
		// TODO Auto-generated method stub
		login =(Button) findViewById(R.id.blogin);
		cancel =(Button) findViewById(R.id.bcancel);
		id = (EditText) findViewById(R.id.edtid);
		pass = (EditText) findViewById(R.id.edtpassword);

	}
	
	

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		switch(v.getId())
		{
		case R.id.blogin:
			

			boolean didItWork=true;
			
			
				String editid = id.getText().toString();
				String editpass = pass.getText().toString();
				didItWork = Verif(editid,editpass);//Verif is a method to compare the entry text in the editText with the value found in the database 
				if (didItWork)
				{
					
					Intent i = new Intent("com.application.activity.MainActivity");
					startActivity(i);
				}
			
				else {
					Dialog d = new Dialog(this);
					d.setTitle("Error!");
					TextView tv = new TextView(this);
					tv.setText("Error ");
					d.setContentView(tv);
					d.show();
				}
			
			break;
			
		case R.id.bcancel:
			
			break;
		
		}
	}
public boolean Verif(String editid,String editpass){
		
		boolean verif = false ;
		double id =Double.parseDouble(editid);
		double pass =Double.parseDouble(editpass);

		for(int i=0; i<tabid.size(); i++)
		{
			if ((id == tabid.get(i)) &&(pass == tabpass.get(i)))
			{
				verif = true;
				break;
			
		}
			}
		return verif;
	}
}

The Logcat display :

I resolve my problem, just change some thing in the file androidManifest.xml by this :

 <activity
            android:name="com.application.activity.MainActivity"
            android:label="@string/app_name"
             >
            <intent-filter>
                <action android:name="com.application.activity.MainActivity" />

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