caused by: java.lang.ClassNotFoundException - eclipse

Question

It is very frustrating that when running said app on a device or an emulator the "Unfortunately, app name has stopped" error came up. I believe that (by looking at the LogCat) I have pinpointed the problem to the error "java.lang.ClassNotFoundException". How I can fix this?
This is my manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.benchaful.newboard"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name="com.benchaful.newBoard.activity"
android:label="#string/app_name"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation" />
</application>
<uses-sdk android:targetSdkVersion="16" android:minSdkVersion="7" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
</manifest>
This is my main layout file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res/com.benchaful.newboard"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollview1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:layout_width="fill_parent"
android:id="#+id/home_layout"
android:orientation="vertical"
android:layout_height="wrap_content"
android:background="#000000"
>
There is some buttons here
<WebView
android:id="#+id/accesskey"
android:layout_width="fill_parent"
android:layout_height="100px"
/>
</LinearLayout>
</ScrollView>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
android:gravity="bottom"
android:layout_alignParentBottom="true"
android:layout_alignBottom="#+id/home_layout"
>
<com.google.ads.AdView
xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adUnitId="a151a7cc8c54403"
ads:adSize="BANNER"
/>
</LinearLayout>
</RelativeLayout>
And this is my LogCat

Answer 1

Check the name of your class in manifest file.
change com.benchaful.newBoard.activity to com.benchaful.newBoard.activity.ComponentInfo
activity android:name="com.benchaful.newBoard.activity.ComponentInfo"...
