Async and skipping frames
0
So I've run into an issue where I have an item that I click in a listview, it does a makes a few extras, and moves on the my next activity. I get an issue where my app goes to a black screen and the Console tells me
I/Choreographer: Skipped 630 frames! The application may be doing too much work on its main thread.
I've tried reading up on Async but I'm not sure how to use it in my code. So I'm posting my Main activity since this happens without interacting with the second activity.

Seems pretty likely that the problem is in the second activity. Is it loading any data to display after you click on the list item?

Nov 13 '18 at 20:09
yes give me a moment to edit it in
– Cristian Espaillat
Nov 13 '18 at 20:11
Hm, nothing jumps out at me (no network connection or db loading is obvious). If you comment out the wholeif (extras != null)block, does the problem go away? Obviously you won't see your items, but this might help verify that loading the items is the slow part.

Okay so it does let me get to the ItemList Activity. It was working earlier when the items were two textviews, but I changed it to one textview to be able to use a filter. might that've been the cause?

Seems pretty likely that the problem is in the second activity. Is it loading any data to display after you click on the list item?
– Ben P.
Nov 13 '18 at 20:09
yes give me a moment to edit it in
– Cristian Espaillat
Nov 13 '18 at 20:11
Hm, nothing jumps out at me (no network connection or db loading is obvious). If you comment out the wholeif (extras != null)block, does the problem go away? Obviously you won't see your items, but this might help verify that loading the items is the slow part.
– Ben P.
Nov 13 '18 at 20:16
Okay so it does let me get to the ItemList Activity. It was working earlier when the items were two textviews, but I changed it to one textview to be able to use a filter. might that've been the cause?

I figured it out. I accidentally made an infinite loop with while in the ItemList activity.
