Using android.jar in Java project - RuntimeException Stub?
<p>I tried to <strong>include android.jar</strong> into Java project, <strong>remove JRE from Build Path</strong> and run this code. It throws Runtime exception. Why?</p>

<pre><code>Exception in thread "main" java.lang.RuntimeException: Stub!
    at android.content.ContentValues.&lt;init&gt;(ContentValues.java:5)
    at JarTest.main(JarTest.java:5)

public class JarTest {
    public static void main(final String[] args) {
        final ContentValues values = new ContentValues();
        values.put("test", "test");
        System.out.println(values);
    }
}
</code></pre>

<p>Why is ContentValues used only in Android environment?</p>
