setContentView上的另一个资源$ NotFoundException

Question

There are lots of Resources$NotFoundException questions on Stack Overflow and I've reviewed them and tried the various suggestions to no avail.

I had a perfectly working layout to display some graphics with some buttons underneath and I modified some of the buttons and started to get this error. I couldn't see anything wrong with my changes but just to narrow it down I deleted ALL the buttons, so now I just have a LinearLayout with an ImageView and I'm still getting the error. My Java:

    try  {
        setContentView(R.layout.graphics);
    }
    catch (Exception e)  {
        Log.d("DGraphActivity", "setContentView crash");   
    }

My XML:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">
   <ImageView 
      android:id="@+id/image2"
      android:layout_width="0px"
      android:layout_weight="2"
      android:layout_height="match_parent"
      android:scaleType="fitCenter">
    </ImageView>
 </LinearLayout>

The error says android.content.res.Resources$NotFoundException: Resource ID #0x7f030005 . In the R.java file that resource is identified with the graphics . . .

public static final class layout {
        public static final int addcomment=0x7f030000;
        public static final int areyousure=0x7f030001;
        public static final int downarrow=0x7f030002;
        public static final int downleftarrow=0x7f030003;
        public static final int downrightarrow=0x7f030004;
        public static final int graphics=0x7f030005;
        public static final int infofromoperator=0x7f030006;

I deleted the gen folder and did a clean the project with no improvement. I also rebooted my PC and did an explicit close of the project. There's nothing obviously wrong with the graphics.xml file - it exists in the same folder with all my other XML files; it's not write-protected or hidden. Eclipse doesn't flag any errors or warnings for it.

Thanks in advance.

Answer 1

I got the answer to this on the android-developers Google groups, where I also posted this question. The insightful programmer was "Bob Smith", just to give credit credit where it's due.

My bug was that the resource it was seeking was not in the correct res folder. My app runs in landscape mode on a tablet. In the manifest everything is constrained to run that way (in fact in the code it's constrained to run on one particular tablet that the company ships with their product). All the resource and layout files live in layout-land. Bob didn't know any of this but he asked the key question: were my resource files really in the right res folder?
