black dots on 9patch image

Question

My app is showing the 9patch black marks. Why could it be?

That's my picture:

You can see the small black dots. The file name is "filename.9.png". I am using the 9patch program that comes with android sdk. That's my code:

<ScrollView
                    android:id="@+id/left_scroll"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" >

                    <RelativeLayout
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content" >

                        <Button
                            android:id="@+id/pic_coupon_calender"
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content"
                            android:layout_alignParentLeft="true"
                            android:layout_alignParentRight="true"
                            android:layout_alignParentTop="true"
                            android:background="@drawable/pic_coupon_news" />
                    </RelativeLayout>
                </ScrollView>

The background is "pic_coupons_news.9.png". What could be the reasons for such a thing?

Thanks!

It happened with me once too.

Just clean your project and rebuild. This should resolve the defect.
