Creating a trivia in Android Studio (6s trivia)

I'm currently working on creating a simple trivia game for Android phones. For now, I just made the algorithm of how the questions and answers work and "designed" the MainMenu with the point system you can see more or less in the gif.

My next step is to implement the firebase service to make a login with Google/Facebook and the database of xp for each player loggedIn.


Then working to the design a little bit better (icons or colors or..)

Then working on a mode that has like a little story behind.

Then adding like 30 000 questions.

One problem I think is gonna make me feel crazy, it's not reset the variables when changing from portrait to landscape and vice versa. If someone knows a better way, or faster way then take each variable and push it like manually, help me..pls


Even if the concept of a trivia game it's very easy, now I'm gonna resume how normal game works. You have 6 seconds to answer a question. For each correct answer you get 2xp + xp time points. You get 4xp time points if you answer in 1 sec. For each millisecond passed after the first second, xp time points decrease by 0.1xp until you have 0.1 sec left -0.9xp time points. If the 6 seconds have passed, you will get penalized with -2.5xp points. If you answer wrong it's -2.5xp too.

I'll update you on my progress. Any help would be appreciated
