问题 I'm having a problem with saving data permanently. It should be simple, I'm sending data to another Fragment and it works perfectly, however, I have no idea how to save data.

问题 In my MainActivity, I have three fragments. There is also a BottomNavigationView that handles what fragment to show. This is what I have in my MainActivity's OnCreate: fragmentManager.beginTransaction().add(R.id.content_main, mTrendingFragment, "3").hide(mTrendingFragment).commit(); fragmentManager.beginTransaction().add(R.id.content_main, mFavoriteFragment, "2").hide(mFavoriteFragment).commit(); fragmentManager.beginTransaction().add(R.id.content_main, mUpcomingViewPagerFragment, "1").commit
