Android application doesn't appear on recent apps list

Question

i'm deploying an android application (Android 4.0.3) and when I press the home screen the application doesn't stay on the recent apps list. I've noticed that when I restart the application, it starts on the last screen i've navigated before press the home button. Anyone can help? Here is me Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.test"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="15" />

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

    <application android:icon="@drawable/logo_home"
        android:allowBackup="true">
        <activity
            android:name="com.test.activity.CommunicatorActivity"
            android:launchMode="singleTop"
            android:label="" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>
        <activity android:name="com.test.activity.InputActivity"
            android:windowSoftInputMode="adjustPan|stateHidden">
        </activity>
        <activity android:name="com.test.activity.SettingsActivity" 
            android:windowSoftInputMode="adjustPan|stateHidden">
        </activity>
        <activity android:name="com.test.activity.OutputActivity"
            android:windowSoftInputMode="adjustPan|stateHidden">
        </activity>
    </application>

</manifest>

I'm going to go out on a limb and suggest that this is your problem:

android:label="" 

In your root activity CommunicatorActivity you've set the label to be an empty string. This label is used to identify your app in the list of available apps and because it is empty, this may be causing it not to show up in the list of recent apps.
