stackoverflow error on view drag drop update

Question

I am using ondragListener for view drag . My root is viewgroup with more viewgroup containers into the root and am adding views like imageview/textview inside the containers .

If I use the only container(ViewGroup) like linearlayout for drag and drop its working fine but if I start adding views like imageview inside these containers and still dragging point is containers only holding this view.

onActionDrop gets an stackoverflow error : stack size 8MB.

onActionDrop code is :

if (e.getAction()==DragEvent.ACTION_DROP) {
        final View view = (View) e.getLocalState();
        final ViewGroup from = (ViewGroup) view.getParent();
        from.removeView(view);
        final LinearLayout toView = (LinearLayout) v;
        toView.addView(view);}

Error Logs :

Your code seems right but the problem may be with the amount of visual components you´re moving from one container to the other, you may need to destroy and recreate the dragged view or something like that.

Can you show the full code, where you assign the `DragListener` to the `Views`, and the code for the `DragListener` itself? — yshahak, Oct 06 '16 at 07:47
I think you may have a cycle in your View hierarchy. A stack overflow on `resetResolvedLayoutDirection` often indicates this. This can happen for a variety of reasons (many documented here at SO if you search), depending on how you create/inflate them. — Turix, Nov 01 '17 at 05:04

I think you should be looking at the TransactionTooLarge exception instead of the StackOverflow one. TransactionTooLarge can sometimes be a hard one to track down but usually it has something to do with too much data being sent between Activity/Fragment or stored in savedInstanceState. As pointed out by @eduyayo in a comment above, you could take a look at this post:

What to do on TransactionTooLargeException

I experienced a similar error a while back and it was due to a huge list was being passed from an Activity to a Fragment and the crash itself occurred in a completely random place.
