Android - exception when compiling and running the application

I am running a debug android application with eclipse and the simulator, and on a restarting of the app, I get this exception,

03-23 02:19:51.384: E/AndroidRuntime(605): FATAL EXCEPTION: main

But this doesn't really say where the error happened in my code. Any idea why this might be happening and how to prevent it?

and this is the entire manifest of the small application:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.problemio"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="15" />

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity

            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity

            android:label="@string/add_problem" />

            android:label="@string/create_account" />         

        <activity

            android:label="@string/problem_page_header" />

            android:label="@string/suggest_solution_header" />  

        <activity
            android:name=".SuggestedSolutionActivity"
            android:label="@string/suggested_solution_header" />          

        <activity
            android:name=".ViewSolutionsActivity"
            android:label="@string/view_solutions_header" />        

        <activity
            android:name=".TopicActivity"
            android:label="@string/topic_header" /> 

    </application>

</manifest>

Thanks!

The real solution to this problem is a folder permissions issue. Make sure you are operating in a folder that you can modify. I just fixed that same problem for my self by making sure I was in a folder with the right permissions.
