Android No Launcher activity found

Question

I am having this problem. I created a new xml layout (splash screen) and in manifest set it as Launcher category. I did this before tons of time but it never happened before.

When MainActivity is LAUNCHER categpry and I run Spalsh Activity via intent it works. Doing opposite I get error No launcher activity found.

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".SecondActivity"
        android:label="Second Activity" >
        <intent-filter>
            <action android:name="net.learn2develop.SECONDACTIVITY" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

No problem in this one, but if I modify it to

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".SecondActivity"
        android:label="Second Activity" >
        <intent-filter>
            <action android:name="net.learn2develop.SECONDACTIVITY" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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