Two launcher activities

I have two activities marked with intent filter

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.package"

android:versionCode="1"

android:versionName="1.0" >



<uses-sdk android:minSdkVersion="7" />



<application

    android:name=".MyApp"

    android:icon="@drawable/ic_launcher"

    android:label="@string/app_name" >



    <!-- work order activity -->

    <activity

        android:name=".app.WorkOrderActivity"

        android:label="@string/work_order"

        android:taskAffinity="com.package.task_for_work_order_activity" >

        <intent-filter>

            <action android:name="android.intent.action.MAIN" />



            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter>

    </activity>



    <!-- inventory activity -->

    <activity

        android:name=".app.InventoryActivity"

        android:label="@string/inventory"

        android:taskAffinity="com.package.task_for_inventory_activity" >

        <intent-filter>

            <action android:name="android.intent.action.MAIN" />



            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter>

    </activity>

</application>

The problem is, that when I'm installing apk file, there is no activity shown, because, as I understood system can't specify what activity should be shown.

I just really need two activities shown in launcher, so please don't give advice about removing intent-filters from second activity, or if you do so provide me another way to show two icons in launcher.

Thanks in advance.
