Side drawer opening requires unpredictable touch zones

[Victor239]

When on an individual post:

• Swiping left-to-right from screen edge triggers the Android gesture navigation "back", which opens the "Exit the app?" prompt. Sometimes opens the side drawer too.
• Swiping left-to-right from the middle of the screen goes back one screen, takes you to the imageboard home. Consistent.
• Swiping right-to-left from screen edge triggers the Android gesture navigation "back", which opens the "Exit the app?" prompt. Consistent.
• Unpredictable area to open the side drawer from this screen. Best chance of doing so seems to me to be swiping left-to-right using the bottom 1cm from the screen edge, but this also usually opens the app switcher.

When on an imageboard home:

• Swiping left-to-right from screen edge triggers the Android gesture navigation "back", which opens the "Exit the app?" prompt. Sometimes opens the side drawer too.
• Swiping left-to-right starting from the left half opens the side drawer. Consistent.
• Swiping left-to-right starting from the right half opens the "Open boards" label. Consistent.
• Swiping right-to-left from screen edge triggers the Android gesture navigation "back", which opens the "Exit the app?" prompt. Consistent.

My ideal solution would be:

• Option to disable "Exit the app" prompts, instead open the side drawer when the swiping left-to-right from screen edge and triggering the Android gesture navigation "back".
• Don't open the side drawer AND start the Android "back" gesture simultaneously - choose one or the other.

It's also unpredictable the touch zones of reply overlays, but I haven't done a full analysis of that yet.

What phone / android version are you on? There is some API I still need to adopt for Android 14 predictive back. On my MI MIX 4, back gesture is always used in lower ~2/3 of both edges, and drawer is pulled open in top ~1/3 of left edge. And this is the same as in Kuroba-EX so I assumed it was working properly. Not an Android guy. So thanks for the feedback!

One difference actually is that the back gesture in a thread will take me back to the catalog, not prompt to exit the app.

Xiaomi Pocophone F1, Android 12 (LineageOS). Can't replicate the 1/3rd and 2/3rds behaviour you mentioned unfortunately but happy to test further.

[moffatman]

Could you do the same tests in some other app like kuroba? So we can isolate whether this is lineage specific maybe?

[Victor239]

Sure. What relevant settings do you use in KurobaEx under Behaviour?

[moffatman]

I think it's default. I didn't touch the gesture exclusion, and "allow screens to be swiped away", as well as "allow the thread screen to be swiped away" are enabled

KurobaEx:

On an individual post:

• Any swipe will take me back to the imageboard home

On imageboard home:

• Left-to-right or right-to-left on screen edge will do the Android "back" gesture icon and will minimise the app to the background.
• Left-to-right anywhere not on screen edge will open the sidebar.

I'm also having this problem. It seems totally random whether swiping back will ask if I want to exit the app, go back to the all threads view or open the side drawer.

Yes the back button handling has certain bugs, I've rewritten it completely now. So hopefully this gets better in the next update.
