The markup in the document following the root element must be well-formed and No resource identifier found for attribute ‘layout_width’ in package ‘android’

This error is in activy_main.xml. All code from activy_main.xml:

Answer 1

The problem is with your Relative Layout and you have given id of a button in it and then closed it…
Just Put this instead of your earlier Relative Layout and tell me if it works or not

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#000000">
