android classpath
<p>In standard Java, the accessible classes are the classes present in the classpath or whose containing .jar file is in the classpath.
 By accessible, I mean that you can refer to these classes in your source code. By example, you can type <pre><code>
   System.out.println("hello");
</pre></code>
because the System class (or rather its containing .jar) is in the classpath.</p>

<p>Is there a notion of classpath in Android ?</p>

<p>What are the accessible classes ?</p>

<p>In particular, how can I make a class in an apk accessible to classes in other apks ?</p>
