no map background

[jochen-01]

In StreetComplete there is no map displayed.
All tasks from StreetComplete are shown at the right places (as far as I can see) but without any streets.

How to Reproduce
On the somewhat old smartphone LG G4 with Android 6 the issue exists. Tried current version 57.1 as well as an old 34.2.

Versions affected
All versions of StreetComlete, at least the 2 I tried (see above).

What is your Android version? (see #5528 )

if #5528 is not an answer: Which version of map you are using? Are quest appearing? Is internet working for other apps? Can you open https://www.jawg.io/en/ ?

[jochen-01]

Hi, yes, I can open https://www.jawg.io/en/ Seems to be a site making money with maps. But if I navigate to the examples (e.g. île de la cité de Paris) the 3d map is shown. Google Maps is not installed, just Osmand with offline maps (works as expected).

Oh then it is https://letsencrypt.org/2023/07/10/cross-sign-expiration and #5528

It's 6.0.

Thank you for pointing me to that issue. I checked the mentioned let's encrypt certificates, the answer was "Die Zertifikatskette ist bereits vertrauendwürdig. Es muss kein Zertifikat importiert werden".

So, I think it's ok?
What do you mean with "which version of map you are using"?

[matkoniecz]

"Die Zertifikatskette ist bereits vertrauendwürdig. Es muss kein Zertifikat importiert werden".

autotranslates to

The certificate chain is already trusted. No certificate needs to be imported

And you are still not seeing the background map?

[matkoniecz]

"which version of map you are using"?

Answered by screenshot (which was hidden).

I see on screenshot airplane logo in top right. Have you enabled airplane mode? If yes, is map downloading when StreetComplete has internet access?

Seems to be a site making money with maps.

and they sponsor service serving OSM-based map tiles used as background by StreetComplete

[jochen-01]

Ok, what I have learned is: Android 7.1.1 is the minimum version required to use StreetComplete.

Would you please update the minimum required Android version of the apk from 5+ to 7.1.1?
Without background maps the app is useless.

Sorry, the phone is owned by a person from Germany.

And you are still not seeing the background map?

No. The phone has been in airplane mode but internet access was enabled. I checked again with airplane mode disabled - no difference.
I updated the screen shot.

This is a duplicate of #5528.

Note that you have to install that certificate for the Android system, not for your browser. (Can't offer guidance on how to do that though, I don't know where to do that.)

This would stop users who installed the certificates from using the app (see this user who is on 5.1)

[jochen-01]

I used CAdroid to import and install the certificate. Still not working.
Since I tried to help another user I give up now.
It's a pity that there exists such hidden dependencies. The app might be interesting for people even less experts than I am. ;-)

[westnordost]

I thought there is a system setting somewhere where you can just add a (root) certificate.

An app that is able to add a root certificate sounds suspect, because that sounds like a huge security vulnerability?

@ironspock could you share what you did to make it work?

[jochen-01]

@ironspock could you share what you did to make it work?

Now it works!
What I have done to make it working: Following the excellent support messages here.

I downloaded the 2 certificates ISRG Root X1 and ISRG Root X2. On the phone in question it could be done by selecting "security" --> "cerificates" in system settings, then "import from memory" (choosing the two .pem files I downloaded from Let's Encrypt).

Thank you for your help.

Edit: urls of the certificates added

This could be a topic that may be worth adding to the FAQ on https://wiki.openstreetmap.org/wiki/StreetComplete/FAQ

The FAQ is not maintained by me, instead everyone is free to contribute, most of the current texts are from @mnalis and @matkoniecz . For the 150+ users of StreetComplete still on Android 7.0 and below, it might be very helpful to have a brief and succinct instruction on how to solve this issue on their phone, certainly they would be thankful if you or someone else added that!

[mnalis]

I've added @jochen-01 instructions to FAQ: The background map is no longer visible after Feb 2024 (on Android versions lower than 7.0)

Improvements welcome, it's a wiki so feel free to contribute.

[ironspock]

@ironspock could you share what you did to make it work?

Sorry for the delay.
I've just exported the ISRG Root X1 certificate from a laptop and installed it on the Android device. However I wasn't able to import it into "Trusted system certificates". So it's (only) a "user certificate". When starting the device I get a related warning message.
