Missing icons for turn instructions

[mvglasow (2)]

Occasionally, the icon for the next turn instruction shows "unknown.xpm". Apparently, icons for some turn instructions are missing.

Tested with r4969 on Android; navit.xml extracted from the apk and stored in /sdcard/navit; the only change is that I commented out TTS settings as I was having issues with TTS on my phone.

As this might confuse users and they might think that navit is broken, I schedule it for hotfix.

Hmm, at least for the linux version, there is a icon. Can anybody please check this against the current Android SVN?

Replying to http://wiki.navit-project.org/index.php/user:usul:

More than just one icon, I hope :-)

Usually it works for me, only in some occasions I got the "unknown.xpm" icon for the turn instruction. Apparently it's just one instruction (or a few) for which the icon is missing.

It's been long since it last happened; if I remember correctly, one instance in which it happened was when Navit instructed me to do a U-turn onto the opposite carriageway (at the end of a dual-carriageway section with no turn restrictions). So the instruction in question must be something like "sharp left turn" or "U-turn left".

Where in the code would I find a list of all possible maneuvers, so I could cross-check that each has an icon? If there's really a missing icon, analyzing the code might be more helpful in tracking down the missing one than merely relying on try and error.

I've examined a similar sitiation using the test suite at ​https://github.com/mvglasow/navit-goodies/tree/master/scripts/routetest and the following test case:

Kruishoutem 3.4905054 50.9148007 3.5010574 50.9187998

The route involves a U turn onto the opposite carriageway. This generates the following maneuver on r5975:

<rtept lon='3.5005643849583628' lat='50.9120419983962549'><type>none</type><name>Turn really strongly left in 300 meters into the Olsensesteenweg N459</name></rtept>

The maneuver type of none explains why we're not getting an icon for the maneuver. This will be fixed as part of Project HighFive?; assigning to myself.

HighFive? has been merged, which should fix this. I did not encounter this issue any more (neither in my test set nor in real life), closing.
