I can not understand what is wrong in my code, any help is appreciated

This is my complete code for Admin class. When I call this class from another class via Intent, app crashes showing no signs of error at all.

I checked the manifest and the build, and cleaned the project more than the words in this post. I have been banging my head for past hour for a solution and still couldn't find one. Please let me know what could be the issue. Any help is appreciated.

Regards.
