Java.lang.IllegalStateException: The application PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged android

Question

I am trying to use a static class to pass value to a view instead of using intent as I have to pass a large amount of data. Sometimes I get this error and couldn\'t find out wha

Answer 1

Sometimes this error occurs.

Here is my suggestion:

In your DataResult->getData()

return a copy of the data.

DataResult is a singleton and holds the data. When your view gets the data, the view gets the data reference witch the DataResult is holding. Then setData() would change the data reference. Here comes the IllegalStateException.

Hope it would work :)
