Tengo un problema al trabajar con estos dos complementos juntos: en el AndroidManifest.xml ambos deben ser "android.intent.category.LAUNCHER"

<application android:icon="@drawable/app_icon" android:label="@string/app_name"     android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:debuggable="false">
        <activity     android:name="com.qualcomm.QCARUnityPlayer.QCARPlayerNativeActivity"     android:label="@string/app_name" android:screenOrientation="portrait"     android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientat    ion|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <meta-data android:name="android.app.lib_name" android:value="unity" />
            <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />
    </activity>
    <activity android:name="com.unity3d.player.VideoPlayer" android:label="@string/app_name" android:screenOrientation="portrait" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
    </activity>
    <activity android:name="com.facebook.LoginActivity" android:screenOrientation="portrait" android:configChanges="keyboardHidden|orientation">
    </activity>
    <activity android:name="com.facebook.unity.FBUnityPlayerActivity" android:launchMode="singleTask" android:label="@string/app_name" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
        <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />
    </activity>
    <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="\ 273811112771671" />
</application>

¿Hay alguna solución disponible para este problema? Creo que es muy común.
