Hi,thanks for the library. I'm having problem with understanding onRiggerBackPressed and onInterruptBackPressed. How can i let the activity's onBackPressed to execute when using onRiggerBackPressed ?

@Devspm if Activity want to interrupt onBackPressed method , you can define a method named onInterruptBackPressed in Activity and return true .

Fragment and Activity is a tree structure , you can choose to interrupt in any level , just return true in onInterruptBackPressed .
