Play store crash report: NPE in ATableViewCell.setPressed

[juliangoacher]

Following stack trace is because ATableViewCell instance gets null when calling getParentView() - how can a view which is capable of handling a touch event have a null parent?

Problem is probably with the list adapter, see following:

Hi, I have the similar issue as well with ADataTable where randomly happens, curious to know do you have any resolution yet?

[juliangoacher]

@sd2020 I haven't looked at this issue since my previous comment, but the problem is almost certainly to do with the data behind the list adapter.

[sd2020]

Appreciate your message, I will keep investigate on this issue. Randomly happen in S7, and LG, but all other devices is fine. Make debugging extreme hard... Worse case have to remove ADataTable view and write my own... I will keep you posted in case find any solutions or reasons.. Thank you.
