Android: keep task's activity stack after restart from HOME
My application has two activities, that I start in this order:

    HOME > A > B

Now I press HOME and launch "A" again. I would like to see activity "B" on a top of "A", but instead I get "A" - so the activity stack is cleared.

Manifest:

    <activity android:name=".activity.A" android:label="A" android:alwaysRetainTaskState="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    
    <activity android:name=".activity.B" android:label="A">
        <intent-filter>
        </intent-filter>
    </activity>

What should I do?
