I'm guessing it has something to do with the App Theme, which in our case is is Theme.AppCompat.NoActionBar.
I have used ZBAR library to scan bar code in my Application.

As you can tell by reading the stack trace, you have a StringIndexOutOfBoundsException, stemming from line 231 of your de.uvwxy.footpath.gui.Loader class, in its onCreate() method.
You're getting a StringIndexOutOfBoundsException in the Loader.java class at line 231. Check the substringing you're doing at that line.
Following the My First Triangle tutorial from this link: My First Triangle
the desktop version works perfectly fine, however when i deploy the android emulator version i get this error:
Unfortunately, MyFirstTriangleAndroid has stopped.
Any suggestions to help fix this problem? I'm using libgdx-0.9.4.

This tutorial is kind of outdated. Google decided to change the way dependencies are referenced, you need to go to your Android project's properties -> Java Build Path -> Order & Export tab, and make sure everything is exported (check the boxes).
I'd highly recommend reading this new article detailing the steps required to setup a libgdx project in Eclipse: http://code.google.com/p/libgdx/wiki/ProjectSetupNew?ts=1339344711&updated=ProjectSetupNew
Additionally i'd recommend going through the new developer guide wiki articles, here is the table of contents: http://code.google.com/p/libgdx/wiki/TableOfContents?tm=6
I'm going through the documentation at Hello, MapView to add a MapView to my Activity.
When I launch my Activity, I get an inflation error on the MapView.
Here is the MapView in my layout xml:
<com.google.android.maps.MapView
android:id="#+id/mymap"
android:layout_width="fill_parent"
android:layout_height="200dip"
android:clickable="true"
android:apiKey="withheld"
/>
Here is the code in my MapActivity (the class is named ActivityDetails and extends MapActivity) class:
MapView mMap;
mMap = (MapView) findViewById(R.id.mymap);
mMap.setBuiltInZoomControls(true);
Here is the error:

As far as I can tell, I've done everything correct as described in the documentation. I've set my build target to Google APIs, I've added the uses-library tag to my Manifest, I'm running in an emulator with the Google API target...
The problem was I was calling super.onCreate() after setContentView() in the MapActivity.
You are using the wrong xml for your MapView
The class extending the MapActivity should call setContentView() with the xml containing stuff like this
<?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">
<com.google.android.maps.MapView
android:id="#+id/racemap"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_x="0px"
android:enabled="true"
android:clickable="true"
android:apiKey="blahblahblah" />
</LinearLayout>
So instead of using layout_details.xml use layout.xml
Insert this on your xml declaration of the MapView
xmlns:android="http://schemas.android.com/apk/res/android"
