SC 45.1: SC shows error when layer switched - stack trace

[pawlosck]

Describe how to reproduce it here:
I don't know. It happened, when I tried to see layers in SC. First, I checked lighting, next pavements and last I set to None (possible translations is wrong, but I am using non english SC). After pavements, SC started shows me popup to send email with this stack trace.
I saw this popup every time when I tried to open SC. After few minutes, everything works correctly and I can't reproduce it again.

Today, SC crashed with the same message. I lost few tasks.

Has it happened with overlay enabled? Has it happened in the same place?

Not really sure is it worth doing - but in case there is some weird corruption you can uninstall and install app again.

[pawlosck]

Today, it happened when overlay enabled, but yesterday, I am not sure. what do you mean the same place? You mean the same place in app? if yes, it happened in few different places.
Yesterday, it happened, when I tried to run app and SC started to find new tasks. Today it happenend when I tried to cut road. SC crashed.

[matkoniecz]

No, in the same place while mapping (maybe OSM data at specific location is triggering some bug? unlikely, but who knows)

[pawlosck]

I suppose 2-3 km. I can try to go other part of city and then I can confirm your suspicions.

[pawlosck]

The same problem. I had overlay disabled and SC still crashing. I checked in other part of the city.
SC crashed when I had new note opened and I minimized SC to see something in Android.
Currently, this app is extremely unstable.

Currently, this app is extremely unstable.

That is very strange; I've been using SC for years and have not seen such case of instability. It seems to be something specific to your device which is crashing inside tangram library used to display the map. Unfortunately debugging this more deeply is beyond me, but it seems to be crashing when trying to clear cached map data.

Could you share:

• from which location did you install the SC 45.1 ? GooglePlay? F-Droid? some specific GitHub page?
• what Android version are you using?
• is there anything special about your phone OS after you bought it (e.g. rooted phone, custom ROM, ... ?)
• what is the amount of Settings / Map cache size?
• what is the amount of free card space on the device (your OS file manager should be able to show that)?
• what phone/mobile device are you using?

What I would also try:

• go to Settings / delete cache. Does the app crash immediately? If not, does it solve the problem or does it reappear?
• if the above does not solve the solve the problem, I would try uninstalling and installing SC again. Perhaps something got corrupted in the past, and now app is unable to recover. Uninstalling and then installing again should fix that. Your score (stars, accomplishments etc) is tied to your OSM account and not specific installation, so it won't be lost. Just upload any possibly pending quests before uninstalling, in order to not lose them.

What I would also try:

* go to `Settings` / `delete cache`. Does the app crash immediately? If not, does it solve the problem or does it reappear?

Your suggestion is great. Yesterday, I cleared cache and today by few hours I was using SC and everything ok.
I hope, it solves problem permanently.
I checked with and without overlay enabled.

[westnordost]

Hmm, I think I found something. Fixed that.
