Map view empty in Öffi, other than Location Markers #8

Closed aphirst closed 8 years ago

aphirst commented 8 years ago

I see that there's another issue (#7) here about Öffi crashing, which I don't experience. Regardless I thought I should post a new issue regarding my own current problem. It relates to another app which doesn't have a Bug Tracker so I thought I'd document it here and then e-mail him with a link to it - I hope that's OK.

I installed the most recent .zip to my Android device running CM12.1 (so Android 5.1.1), also with microg installed from F-Droid (up to date, AFAIK). Before I did this, the "normal" builds of Öffi in the developer's own F-Droid repo refused to install - afterwards, the install was successful.

There are a few modes in Öffi that can display a map, e.g. the one for showing nearby stations. The map pane is visible along with a location marker (indeed, when in an appropriate route mode, other location markers are also visible, e.g. for your destination too), but with no map content. I wondered whether there was a setting or something that I'd forgotten to properly configure but as far as I can see there isn't a settings menu for this Maps "package".

I will have time later in the week to try to get some actual debug output, and once I do, I'll post that in a reply. Also if there's any other information that would be useful, don't hesitate to ask. I'll provide that too once I have the time.

Oh, first clarification, I have actually installed this from the other Github repo by the same author, as this repo does not have release builds as the Readme claims. I had actually "confused" the two projects, though I am (mostly) confident that they are in fact the same project.

I'm not sure whether the Öffi developer intends himself to post in here, but nonetheless he asked me the following question, which seems apt to post (translated) here:

Who is it that's actually providing the OSM-Tiles for the MapsV1 implementation?

Your symptom description makes me think there is a problem with the Google server authentication (Maps V1 API key).

@schildbach, potentially related or helpful: I got a crash when "playing" with the map view this morning (specifically, I was zooming in and out), and Öffi spat out a debug log of sorts. I saved it, and have just now extracted it from my device: http://sprunge.us/IKBf

@aphirst this is a known problem with the old mar-v-in/MapsAPI implementation with latest Android versions due to changes in SD-card access (tile cache is written to sdcard) The latest version (this repo) does not suffer from that problem, but has the problem described in #7, once it's fixed there will be a new release. Long term goal is to redirect Maps API v1 calls to Maps API v2, so we can have all its nice features and focus work on a single, vector-tile-based Maps implementation.

As this issue is present in mar-v-in/MapsAPI, but should not be in this repos release, I'll close here.
