Android Phone app crashes as soon as I run it on a phone

I'm trying to just create a basic android app, and when I load it onto a phone and try to run the app it just crashes. Can someone take a look at it for me?

My manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.workexp1"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity android:label="@string/app_name"
          android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
</activity>
    </application>

</manifest>

If you MainActivity does not live in the same package as the one specified in the manifest (in this case com.example.workexp1) then the dot notation won't work.

change this line

android:name=".MainActivity">

to

android:name="com.yourfullpackage.MainActivity">

java.lang.ClassNotFoundException: com.example.workexp1.MainActivity in loader dalvik.system.PathClassLoader[/data/app/com.example.workexp1-1.apk]

This exception means that there is no such class named MainActivity in your project. So check your project and see what's going on.
