android ANR after switching to a new activity

I am making an RPG and I started by making the battle system, then I decided to make the overworld a seperate activity so I copied the Game loop class and made a duplicate, when I switch to the battle mode class, none of the buttons respond and then this error comes up

I believe it may have to do with the fact that they both have their own threads but something isn't right - can anyone help me?

We really can't answer this question without more information. What I can say is this, if you are new to game development I'd suggest you consider using one of the many excellent game engines out there. Two quite popular engines are:

1. AndEngine
2. LibGDX

They are both quite mature and have a strong community of users.
