How do I resolve the ActivityNotFoundException?

I'm getting an ActivityNotFoundException in my Android Application.. Here's the code snippet I have put to call the activity : 

Intent i = new Intent();
i.putExtra("NAME", username.getText().toString());
i.setClassName(getPackageName(), SecondActivity.class.getSimpleName());
startActivity(i);

my AndroidManifest.xml looks like this

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

<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA"/>

<application android:icon="@drawable/ic_launcher" android:label="@string/app_name" >
    <activity android:name=".firstActivity" 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:label="@string/app_name" android:name=".SecondActivity" />
    <activity android:label="@string/app_name" android:name=".WelcomeActivity" />
</application>

</manifest>

When I execute the code snippet with the intent, I get the following exception.

E/AndroidRuntime(731): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.rangde/WelcomeActivity}; have you declared this activity in your AndroidManifest.xml?

Can someone tell me what I'm doing wrong?

Intent intent = new Intent().setClass(Class1.this, Class2.class);

i.putExtra("NAME", username.getText().toString());

startActivity(intent);

instead of writing 

i.setClassName(getPackageName(), SecondActivity.class.getSimpleName());

try with

i.setClassName(getPackageName(), SecondActivity.class.getName());

SecondActivity.class.getSimpleName() returns only name of the class.

if u write SecondActivity.class.getName() get fully qualified class name(with the package name)

use this

 String packageName = this.getPackageName();
 i.setClassName(packageName ,packageName  + "." + SecondActivity.class.getSimpleName());

instead of

i.setClassName(getPackageName(), SecondActivity.class.getSimpleName());

Intent i = new Intent(this,SecondActivity.class);
i.putExtra("NAME", username.getText().toString());

   //set your classname here
  Intent i = new Intent(firstActivity.this, SecondActivity.class);
   i.putExtra("NAME", username.getText().toString());
startActivity(i);
