I am showing a toast for already processed items from my utils file.
The scenario I am facing is that if I scan 10 items, and I change my screen, the toasts are still in process and my app crashes with
Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@321daf0 is not valid; is your activity running?
Below is the code that I am using.
In Activity
UtilityMethods.showToast(this, "message"));
In UtilityMethods
public static void showToast(Context c, String s) {
Toast.makeText(c, s, Toast.LENGTH_SHORT).show();
}
What I tried
I tried adding a try catch block like this:
public static void showToast(Context c, String s) {
try {
Toast.makeText(c, s, Toast.LENGTH_SHORT).show();
}
catch (WindowManager.BadTokenException e){
e.printStackTrace();
}
}
But it is still crashing.
The full exception is below:
Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@321daf0 is not valid; is your activity running?

I also found some other solutions on SO but it did not work.
Please suggest what can be done in my case, thanks in advance.
