+ * <strong>Note:</strong> Starting from {@link android.os.Build.VERSION_CODES#LOLLIPOP_MR1}, the
+ * behavior of this API is changed such that passing <code>null</code> as the <code>admin</code>
+ * parameter will return if any admin has blocked the uninstallation. Before L MR1, passing
+ * <code>null</code> will cause a NullPointerException to be raised.
