IBM Worklight - exception when trying to open application in Android device

I am totally new to Worklight, and I am helping to work on a project which is shared on CVS. First time, my co-work help me set up everything and the app runs okay on my Samsung SII 2.3 version phone. But after I failed to change the apps' name and mess up the code. I re-download the project from CVS, I can't open the apps anymore and it forced me to close it.

Here is the error log:

I did some research about the similar situation, and most ppl said that will be caused by not adding the activity name to the AndroidManifest.xml, however, I don't know or think I have extra activity name need to be covered.

So, someone can help?

AndroidManifest.xml

In addition to what I have mentioned in my comment to your question, the most common cause to this is using Worklight 5.0.5/6.x in conjunction with ADT v22.

To fix the issue, follow these steps:

  1. Right-click on your generated Android project and choose "properties".
  2. From the left pane, choose "Java Build Path'
  3. Tick the "Android Private Libraries" checkbox
  4. Refresh the project / re-build the app

As for changing the name of the application, see instructions in this SO question: IBM Worklight - how to rename an application and change its icon, splash image
