Owntracks (Android) crashes with csv format on the friends view

See original GitHub issue

App Build number: 23024 Android 10.0.1 (OxygenOS OnePlus 5T) latest official release

I use a little wemos with gps hat and your pico homie sketch, works great. As i want to have full data, i switched from json to csv format and since then, the android owntracks app crashed, when i switch to the friends view. (Info: I changed to lat/long coordinates somewhat for privacy reasons)

The log shows:

I thought it was mentioned, that csv is supported, was that an old information or is this a bug in the parsing code ?

Thanks, Ronny

Seems legit, i already did use the cards since some short time and tried the friends feature in the app a long time not. So this was not obvious to me. Many thanks for pointing me to this and sorry for duplicate report on this. Keep up the good work.

Aha! This smells similar to #984 - the app assumed that if it knew about a contact, then that contact has a valid location. Obviously, this isn’t necessarily true.

NullPointerException: Attempt to invoke virtual method 'java.lang.String org.owntracks.android.model.messages.MessageLocation.getGeocode()' on a null object reference is the key line, when displaying the contact, it tries to reverse geocode the location (for display). Sometimes, there is no location. Then it explodes.

It’s hopefully fixed in the next version. I should really get that released.
