Although I had mentioned everything in my Manifest File. My manifest.xml file is as follows:-

    </application>

</manifest>

I had tried all other possible methods such as, Clearing the Projects, Adding External Jars. Restarting Eclipse several Times, but nothing has worked for me.

Note:- If I run the same project on Samsung Galaxy S3, no logcat output is obtained and the App simply crashes, whereas if I run the App on the Emulator it gives the LogCat output and crashes, Hence the LogCat output I did provided is of my Emulator.

Any help would be Appreciated.

Then your class name is com.thehealthsite.StoryListActivity (without ui) — Arno van Lieshout, Oct 15 '14 at 11:00
If the name of your class is StoryListActivity and the package noted above the class is com.thehealthsite then your class name is com.thehealthsite.StoryListActivity — Arno van Lieshout, Oct 15 '14 at 11:03
@Arno well i had created a new package for my ui widgets, there are around 8 packages in my parent com.thehealthsite package. com.thehealthsite.ui is my child package of com.thehealthsite. — Pravinsingh Waghela, Oct 15 '14 at 11:27
@Arno well there is no error in my class file as the class file is working well on my other apps to. I am just making a replica of already made App, with new name and new Package name. Same structure had worked well before. — Pravinsingh Waghela, Oct 15 '14 at 11:35
