How Can I Fix This Intent Issue?

TL;DR: How can I give one intent a preference over another? If two intents are run at the same time, I want only one of those intents to start. My game has a 20 second timer runni

Solution 1:

do timer checking on user click event should do it. or you can use flag/boolean to maintain state.

i dont know your code, just use simple conditional if..

 if (timer <= 0){
      //open whatever u want and reset timer again..
 }

Solution 2:

I am suggesting you to take a global variable as a flag, let say int = 0 Now initialize it as "0" and on your both intents give condition as below:

 if(i == "0"){
    .
    .
    .
    //fire your intent..
i= 1;
    }

,And then flush that variable to "0" whenever you want.Hope you got idea.
