Android : My Android app crashes Unexpectedly

I am a beginner to Android Programming. I am learning it through the new boston videos. But every time i start my app it crashes "Unfortunately app stopped working" But when i click OK it takes me to the second activity in the app. I am not able to figure out why is it happening.

Here goes my Android Manifest:

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

<uses-permission android:name="android.permission.SET_WALLPAPER" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Splash"
        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=".StartingPoint"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.skm.firstapp.STARTINGPOINT" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name=".Menu"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.skm.firstapp.MENU" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
     <activity
        android:name=".Prefs"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.skm.firstapp.PREFS" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name=".TextPlay"
        android:label="@string/app_name" >
    </activity>
    <activity
        android:name=".Email"
        android:label="@string/app_name" >
    </activity>
    <activity
        android:name=".Camera"
        android:label="Camera Application"
        android:screenOrientation="portrait" >
    </activity>
    <activity
        android:name=".Data"
        android:label="Data App"
        android:screenOrientation="portrait" >
    </activity>
    <activity
        android:name=".OpenedClass"
        android:label="Data App"
        android:screenOrientation="portrait" >
    </activity>
    <activity
        android:name=".AboutUs"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Dialog" >
        <intent-filter>
            <action android:name="com.skm.firstapp.ABOUT" />

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

</manifest>
