Android manifest.xml problems

[Dennismn]

Following this: http://developer.android.com/training/basics/firstapp/starting-activity.html I am confused when editing the Android Manifest.xml file. It says that the file should contain this: \[code\]<application ... > <activity android:name="com.example.myapp.DisplayMessageActivity" /> ... </application>\[/code\]My android manifest.xml looks like this:\[code\] <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.nick.myfirstapp" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15" /> <application android:label="@string/app_name"> <activity android:name="com.nick.myfirstapp.DisplayMessageActivity" /> ... </application></manifest>\[/code\]and when I run the app everything goes fine except it says : "No Launcher activity found! The launch will only sync the application package on the device!" Is this something missing from the android manifest.xml file?
