Проект библиотеки Dx НЕОЖИДАННОЕ ИСКЛЮЧЕНИЕ ВЕРХНЕГО УРОВНЯ или ActivityNotFoundException

У меня есть проект библиотеки и обычный проект Android, который его использует.

Библиотечный проект:

папка src пакет com.myproject

MainActivity
ChildActivity

AndroidManifest.xml

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.project.library">
        <uses-sdk android:minSdkVersion="8" />
        <application>
            <activity android:name="com.myproject.MainActivity">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
            <activity android:name="com.myproject.ChildActivity">
            </activity>
        </application>
 </manifest>

Отдельный проект (является проектом Android и использует проект библиотеки):

папка src пакет com.myproject

ChildActivity

AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.project">
        <uses-sdk android:minSdkVersion="8" />
        <application>
            <activity android:name="com.myproject.MainActivity">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
            <activity android:name="com.myproject.ChildActivity">
            </activity>
        </application>
</manifest>

Чего я хочу достичь:

ChildActivity из проекта Android должен переопределить ChildActivity из проекта библиотеки.

Компиляция не удалась:

Если я изменю папку src в автономном проекте на com.myproject.standalone и изменю запись манифеста на

<activity android:name="com.myproject.standalone.ChildActivity">

Я получил исключение:

android.content.ActivityNotFoundException: Unable to find explicit activity class
