Manifest Merger not working
<p>I think the manifest merger doesnt work for me. Im running latest Android Studio 2.2.3</p>

<p>My Project has
:App - Application
:Library - Library Project</p>

<p>The Library has all activities. The app shall just use it and launch its default activity. Im just getting this error msg:</p>

<pre><code>Error running App Default activity not found
</code></pre>

<p>This is my apps manifest:</p>



<pre><code>&lt;manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="trainer.de.next"
    xmlns:tools="http://schemas.android.com/tools"&gt;

&lt;/manifest&gt;
</code></pre>

<p>The merged manifest shows not more, this is the report:</p>

<pre><code>Manifest Sources 
app main manifest (this file)
 Other Manifest Files (Included in merge, but did not contribute any elements) multidex:1.0.1 manifest
</code></pre>

<p>In the build.gradle of app im using the library</p>

<pre><code>...
dependencies {
    compile project(':library')
}
</code></pre>
