Because you are removing a new fragment? That doesn't really make sense

Pretty sure you need to track your reference the fragment you want to remove by giving it a tag when you passed it into the stack

[vast trellis]

Can you please explain more? Or even give me the correct code?

[molten jungle]

One Google search could clear this out for you:

[vast trellis]

How can I find said tag or Id?

@molten jungle

[molten jungle]

Where are you adding the fragment

[vast trellis]

Inside an activity

Its a full screen fragment

[molten jungle]

Yes, you set the tag there

[vast trellis]

But what is the tag itself

Is it the name of the javafile? Xml?

if i try to do it crashes

        final FragmentTransaction ft = getParentFragmentManager().beginTransaction();
        ft.remove(getChildFragmentManager().findFragmentById(R.id.fragmentGallery));
        ft.commit();

    }```

[molten jungle]

how are you adding the fragment

please show that code

is it declared in XML already?

This doesn't show of what I asked

where are you initially setting the fragment that you are removing?

[vast trellis]

        new GalleryFragment().show(getSupportFragmentManager(),
                "fullscreen dialog fragment");


    }```

this inaide the activity

[molten jungle]

is that second string argument not your tag?

[vast trellis]

it is the tag

[molten jungle]

so fragmentManager.getFragmentByTag("fullscreen dialog fragment")

[vast trellis]

should i put it inside the activty or inaise the fragment

[molten jungle]

put what

that is how you get the fragment so you can remove it

remove it wherever you were before

[vast trellis]

No but like should I put the code on the activity java file or the fragment java file

[molten jungle]

what code

[molten jungle]

wherever this code was

[regal pawn]

what are you trying to do

well yeah it doesn't remove an object because you're not removing it

instead you created a new object and removed it

[vast trellis]

The code you just sent me

[molten jungle]

yes, I told you where to put it already

[vast trellis]

After you click a button, close the fragment

[molten jungle]

the problem was you didn't have a way to reference the fragment you wanted to remove. now you do so what's the issue?

[vast trellis]

I need to run it and see if it works

a lot of the online solutions don't work since I have a costum made fragment

[regal pawn]

instead of referencing the object that you want to remove

you're referencing a new object

that you made

you're removing an object that you made in the same line you're removing it

[vast trellis]

So what am I suppose to replace it

[regal pawn]

guess

you should have at least basic java knowledge before doing anything...

[vast trellis]

@molten jungle thanks it worked
