In LogCat you see that:

com.satyamdswt.agreader/com.satyamdswt.agreader.ContactsListActivity

I don't know why this happened two times.

For more I display my Manifest.xml here: Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.satyamdswt.agreader"

</manifest>

Please guide me where is Error.

ContactListActivity.java

public class ContactsListActivity extends ListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.contacts_list);
        setListAdapter(Adapters.loadAdapter(this,R.xml.contacts ));
    }

}

I've recreated your error. Problem is in your res/xml/contacts.xml file

Change this line:

xmlns:app="com.satyamdswt.agreader"

to this line:

xmlns:app="http://schemas.android.com/apk/res/com.satyamdswt.agreader"

It is right format of XML namespace of your app: http://schemas.android.com/apk/res/package_name

Upd: You shouldn't change other parameters in the <cursor-adapter> tag. Right form:

<cursor-adapter xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res/com.satyamdswt.agreader"
    app:uri="content://com.android.contacts/contacts"
    app:selection="has_phone_number=1"
    app:layout="@layout/contact_item">
