Ugly nine-patches, not scaling right

Question

A made some nine-patches for my buttons in Android but they scale in an ulgy way. The weird thing is that they are only ugly in one specific Android project.

I have no idea what cause the nine-patch to scale bad. This is the XML used in the badly scaled project, it is the same in the good scaled project.

<Button
    android:id="@+id/issueShare"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:layout_marginLeft="5sp"
    android:layout_marginRight="5sp"
    android:background="@drawable/button"
    android:text="Delen" />

Answer 1

I found the solution on a place I would never look. The problem was that in my Android Manifest I didn't specify the android:targetSdkVersion, only the minSdkVersion. After setting the android:targetSdkVersion the nine-patches scaled fine.
