Errors possibly associated with R.java

my android app development ran into the issue with the R.java file not appearing and causing a host of other errors. I believe that might be remedied or either will be after I fix these Console Errors:

[2014-05-03 18:13:58 - Tag] W/ResourceType( 1008): Bad XML block: node attributes use 0x161aa8 bytes, only have 0x14 bytes
[2014-05-03 18:13:58 - Tag] W/ResourceType( 1008): ResXMLTree_node header size 0 is too small.
[2014-05-03 18:13:58 - Tag] H:\android stuff\projects\Tag\res\menu\display_map.xml:6: error: No resource identifier found for attribute 'showAsAction' in package 'com.JTInc.tag'
[2014-05-03 18:13:58 - Tag] H:\android stuff\projects\Tag\res\menu\map.xml:6: error: No resource identifier found for attribute 'showAsAction' in package 'com.JTInc.tag'

I am not sure based on these what I should do. This the code for map.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.JTInc.tag.MapActivity" >

    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:title="@string/action_settings"
        app:showAsAction="never"/>

</menu>

So do I need to edit something on line 6? Would this be causing the resource file to not correctly work? All help is greatly appreciated. Thanks

Solution

Inside your <item> tag (which is on line 6), you need to change app:showAsAction="never" to android:showAsAction="never". In order for R.java to build properly, your XML needs to be error-free, which is why you get the R.java error.
