Fragment already added, dialogfragment?

Question

I have a dialogfragment which displays fine but some time when I try to display it I keep getting IllegalStateException

Below is the logcat

java.lang.IllegalStateException: Fragment already added: SelectPlan04Dialog{fa768dc #7 }

This is the code as how I am calling the dialog

if (selectPlan04Dialog == null) {
    selectPlan04Dialog = new SelectPlan04Dialog();
}
if (!selectPlan04Dialog.isVisible() && !selectPlan04Dialog.isAdded()) {
    Bundle b = new Bundle();
    b.putSerializable("moduleApi", module);
    selectPlan04Dialog.setArguments(b);                
    selectPlan04Dialog.show(getCurrentActivity().getSupportFragmentManager(), "");
}

Answer 1

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()

but is it ok to call executePendingTransactions ? I am experiencing ANR because of to many calls to show – Jeri

Answer 2

 modalBottomSheet.show(supportFragmentManager.beginTransaction().remove(modalBottomSheet),ModalBottomSheet.TAG)

Сall like this

This actually seems to work well – Rhinoscopy

Answer 3

Here is my solution, I have tried clicking "Show dialog fragment" by tapping the button multiple times 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();
}
