The screenshot is useless. You should look into the logcat output and post it here if you still can't find the root problem. — Neoh, Jun 17 '13 at 11:37
try un-installing the application, clean- build your project and then run the project.. — CRUSADER, Jun 17 '13 at 11:43

This is not the log output you need to look at. Here : how to open logcat in eclipse => http://stackoverflow.com/questions/3280051/how-to-enable-logcat-console-in-eclipse-for-android. then post the logcat stacktrace here. — Guian, Jun 17 '13 at 11:48

This shows that your application is crashing due to some reason. Debug your Main Activity in your case it is Welcome.java. Place debug point in your onCreate and other callback methods, i.e onResume(), onPuase(), Also provide complete stack-trace, what trace you have provided is useless. Please also privide code of your Welcome Activity.
