Answer 1

Here my solution, I have try to click show dialog fragment by tap button multiple time and quickly.

        try{
            FragmentManager fm = getSupportFragmentManager();
            Fragment oldFragment = fm.findFragmentByTag("wait_modal");

            if(oldFragment != null && oldFragment.isAdded())
                return;

            if(oldFragment == null && !please_wait_modal.isAdded() && !please_wait_modal.isVisible()){
                fm.executePendingTransactions();
                please_wait_modal.show(fm,"wait_modal");
            }
        }catch (Exception e){
            e.printStackTrace();
        }

Answer 2

Fragment transactions are asynchronous.

It is possible that you have two or more calls to this code before the fragment transactions are executed. !selectPlan04Dialog.isVisible() & !selectPlan04Dialog.isAdded() condition is true and show() schedules another fragment transaction to execute later.

Some options for fixing this:

• Create a new dialog every time and don't try to reuse an old one
• Change asynchronous fragment transactions to synchronous with a call to fragment manager executePendingTransactions()
