Before you change my question, because you do not see any code (a ridiculous reason for downvote), read it.
Problem
The problem is that even when I change my code and run it on my phone, it will be launched, but the application will not really be changed.
For example: if I had Toast that would say "hello world"in onCreate, but then I changed the text to "should be updated"and then ran it, the toast will still say "hello world".
What caused the problem
I updated my SDK tools and then updated Eclipse. I updated all my Android SDK tools that required updating in the SDK manager. Then I did this to update eclipse:, Help --> Install New Software...then I clicked Add..., then introduced the "ADT plugin" for the name and https://dl-ssl.google.com/android/eclipse/for the location. Then I updated and restarted Eclipse or something else.
Here is a screenshot of the loading of my workspace:

What i tried
- Uninstall the application on my phone and launch it
- Removing the application on my phone, changing the name of the application package, and then launching it (although I did not understand if this would work because Eclipse was so bad that it did not allow me to even run the application on my phone). I changed the name of the package before, and I know how to do it. Eclipse sucks, not me.
