Apk installed on the device but I don't see it in the apps

Question

I wanted to tweak a piece of sample code from API Demos group - GridLayout0. For it I created a separate project and copied GridLayout0.java into it. Now when I try to see the results of my changes, I get in the LogCat is

Uploading GridLayoutSampleTwicked.apk onto device '0388920542204257'
Installing GridLayoutSampleTwicked.apk...
Success!
/GridLayoutSampleTwicked/bin/GridLayoutSampleTwicked.apk installed on device
Done!

Apparently the apk is successfully installed on the device, but I don't see the app in the list of apps where I could launch it from (Wasn't it supposed to launch right after it was installed anyway?)

I am a noob, might have missed something.

If it matters, while creating the new project Eclipse asked me about the "root parent." I had to link it back to the API Demos package because Eclipse wouldn't let me proceed with the new project.

verify if this element exist in your main activity on manifest.xml :

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