App crashes on startup on android API 10 but not on API 16 because of Resources$NotFoundException

My app launches and starts fine on my Samsung Galaxy S3 phone running Android 4.1.2, but when I try to test the same app on my Motorola Droid X running Android 2.3.4 the app crashes before anything is even displayed on my Droid X screen.
My LogCat is below. Unfortunately, it does not point me to exactly what part of my code it is failing on, but it seems like something to do with my layout because of these exceptions:

Fixed!!
Looking into it more and it looks like it had something to do with the ArrayAdapter as well as my layout. I was using a custom layout (drawer_list_item.xml) for my ArrayAdapter which had some ICS specific code I am guessing, so I just had to remove some lines from that XML file and the app launched fine on Android API 10 (specifically Android 2.3.4). The lines specifically in my layout file that caused problems was:
android:background="?android:attr/activatedBackgroundIndicator"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
Here is the code in my SherlockFragmentActivity that was causing the layout exception/crash:
m_drawerList.setAdapter(new ArrayAdapter<String>(getSupportActionBar().getThemedContext(),R.layout.drawer_list_item, m_drawerNames));
OLD drawer_list_item.xml code:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"<!-- Deleted line-->
android:gravity="center_vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:textColor="#fff"
android:background="?android:attr/activatedBackgroundIndicator"<!-- Deleted line-->
android:minHeight="?android:attr/listPreferredItemHeightSmall"/> <!-- Deleted line-->
FIXED drawer_list_item.xml code:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:padding="16dp"
android:textColor="#fff" />

Are you using ActionBarSherlock or HoloEverywhere? I've experienced this problem a lot when using those libraries and trying to style/theme things.
Basically, some attributes are specified by default in ICS+, but are not specified in older versions of android. So, you have to mirror resources, as shown here:
http://actionbarsherlock.com/theming.html
Posting your code for the themes/styles might be helpful for us to see whats wrong.

Without more code I cannot tell you exactly why the app is failing. All we know is that you might use some feature available only for higher APIs. Post your xml-layouts and maybe your classes.
However, try to include the Support Library. That often solves the problem.

I have also tried every possible search here and tried resolving library dependencies but still can't get out of this error.
I am also attaching a screen shot of facebook sdk reference error, if it can help you in suggesting me a solution.1
If there is solution to this problem in another thread then please direct me towards the link.

It seems you renamed your mainactivity class and didn't update the android manifest.

Why does my program crash after I add Listview? Android

I am attempting to connect a listview lv to its id using
ListView lv = (ListView) findViewById(R.id.ImTrackingListView);
However whenever it hits this step my program crashes and sends it to the Source not found page.
Here is my code
public class ImTracking extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.imtrackinglayout);
ListView lv = (ListView) findViewById(R.id.imtrackinglistview);
I checked to make sure that there wasn't another id with the same name. Hopefully someone can help me find out why this is happening.
edit here is the xml (I changed the id to lowercase)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/imtrackinglistview"></ListView>
</LinearLayout>
Here is my logcat response

Try cleaning your project, for some reason the error contains a TextView.

There is a class cast exception in ImTracking file , post the error from log cat.Select E - and the last exception thrown would be in red , paste that.
