Importing class from another project doesn't work
<p>I'm trying to use a class of another project in an app. In Eclipse I've added in the project properties under Java Build Path the other project and under Libraries the the class folder of the project. In the Package Explorer at Referenced Libraries the referencend class is visible under (default package).</p>

<p>While writing the code I could use the referenced class without problems and compiling the app throws no warning or errrors, but when the app starts, logcat shows the following:</p>

<pre><code>dalvikvm(16174): Could not find class 'de.project.myproject1.myclass', referenced from method de.project.myproject2.myActivity.onCreate

<p>So has someone a hint, what to do to solve the problem, I've spent the whole day without a solution?</p>
