Build errors while using Android library project

Question

I'm trying to use this library project on github:

https://github.com/pakerfeldt/android-viewflow

This Android library project provides horizonally swiping.

I will explain my moves how I'm trying to use this library:

1. I downloaded this project from github, and imported "viewflow" project with "Existing Projects into Workspace". (Eclipse gives some errors but I fixed them. It is not the problem.)
2. I created a new android project which name is "test".
3. I added viewflow project to the my test project's build path. (Using Java Build Path->Projects->Add)
4. Here is my main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res/com.example.test"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/header_layout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="vertical" >

        <org.taptwo.android.widget.TitleFlowIndicator
            android:id="@+id/viewflowindic"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dip"
            app:clipPadding="5dp"
            app:footerColor="#FFFFC445"
            app:footerLineHeight="2dp"
            app:footerTriangleHeight="10dp"
            app:selectedColor="#FFFFC445"
            app:selectedSize="12dp"
            app:textColor="#FFFFFFFF"
            app:textSize="11dp"
            app:titlePadding="10dp" >
        </org.taptwo.android.widget.TitleFlowIndicator>
    </LinearLayout>

    <org.taptwo.android.widget.ViewFlow
        android:id="@+id/viewflow"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:duplicateParentState="true" >
    </org.taptwo.android.widget.ViewFlow>
</LinearLayout>

But Eclipse gives these errors:

I imported its example project ( https://github.com/pakerfeldt/android-viewflow/tree/master/viewflow-example ), it just works fine!

The problem could be about namespaces but I couldn't fix this.

Answer 1

app:selectedSize="12dp" remove this line
